4 SOLPLUS Inverters S series 1-phase SOLPLUS 15 S SOLPLUS 40 S2 SOLPLUS 50 S2 More information can be found on our download page at SOLPLUS 15 S 2 Operating conditions The transformerless inverters stand out thanks to their small and compact design and a focus on key communication interfaces. By combining several of these inverters in one PV installation, it s possible to make optimum photovoltaic use of small roof areas that face in different directions and have different shadowing conditions, especially in the case of the SOLPLUS 15 S. Power ratings SOLPLUS 15 S: 1.5-kW rated AC output SOLPLUS 40 S2: 4.0-kW rated AC output SOLPLUS 50 S2: 5.0-kW rated AC output Operating principle and installation planning The SOLPLUS 15 S is a transformerless, single-phase, gridconnected inverter equipped with a boost converter. By contrast, its big brothers, the SOLPLUS 40 S2 and SOLPLUS 50 S2, are kitted out with two MPP trackers and are capable of combining different roof alignments and varying degrees of shadowing as a result. The wide input voltage range of these inverters also enables a broad selection of modules to be connected. The inverters operate even when insolation is relatively low and they therefore make the most of the sunshine available. Grid monitoring All SOLPLUS inverters are equipped with a software-controlled, grid and installation protection function that measures the grid frequency and grid voltage at regular intervals. The requirements differ from country to country and installation settings can be easily adjusted to comply with national requirements and the peculiarities of national grid systems by means of the Setup menu. The safety-relevant parameters are protected by various password levels. Communications model The inverters are equipped with a built-in Ethernet port that offers an inexpensive and fast way to read out the data of large installations via the internet. When it comes to communication, SOLPLUS S series inverters are equipped not only with a display, but also two M12 plug-in connectors that can be used to network several SOLPLUS inverters by means of RS485 ports and to integrate external devices (e.g. SolarLog, SOLCOMBOX). And it goes without saying that a data logger, annual energy logger as well as a fault and alarm memory are integrated.

18 SOLPLUS Inverters 2-phase SOLPLUS 60 2P SOLPLUS 80 2P More information can be found on our download page at SOLPLUS 60 / 80 2P 16 Operating conditions These inverters are suitable for installation in small and mediumsized systems. Their compact design means that they are simple and fast to install and easy to service. In combination with the DE-ICING BOX 2P, SOLPLUS 60/80 2P inverters can also be used in feedback mode. Power rating range These inverters cover nominal AC power ratings from 6 to 8 kw. Principle Solutronic s SOLPLUS 60/80 2P inverters are transformerless, two-phase, grid-connected, solar inverters. Each phase has its own MPP tracker, so that each MPP tracker can be assigned individually. This in turn enables the inverters to be used in installations in which the modules are installed on differently pitched roofs. Grid monitoring All SOLPLUS inverters are equipped with a software-controlled, grid and installation protection function that measures the frequency and voltage of each phase at regular intervals. Monitoring of the grid is performed separately for each phase. The country-specific grid requirements can be set by means of the Setup menu. The safetyrelevant parameters are protected by individual passwords. Approvals/certification See data sheet Languages All language versions offered by Solutronic are integrated in every inverter. You set the language you want by means of a selection menu. Enclosure The enclosure of the inverters is compact. Thanks to their high level of efficiency, the inverters are cooled solely by means of their heat sink. The enclosure fulfils IP65 and all connectors also comply with this degree of protection when plugged in. We also supply suitable mating connectors as accessories for making an IP65-compliant Ethernet connection. DC connectors We supply our inverters with LC4 connectors from Lumberg (MC4- compatible). Installation instructions During the development and design phases, importance was attached to keeping the enclosure lightweight in order to make it easier to handle. To simplify installation, simply mount the inverter mounting bracket to the wall first and then attach and secure the inverter to the bracket. The inverters can be mounted without having to ensure a minimum lateral clearance between them and other inverters because they are cooled by means of vertical convection.

22 SOLPLUS Inverters 3-phase SOLPLUS More information can be found on our download page at SOLPLUS Operating conditions These inverters are suitable for installation in medium-sized and large-scale systems. Their compact design means that they are quick to service even when part of large installations. Such string inverters enable largescale systems to be set up cost-effectively, while guaranteeing high yields and optimised servicing. In combination with the DE-ICING BOX 3P, SOLPLUS inverters can also be used in feedback mode. Power rating range These inverters cover the nominal AC power ratings 8.0 kw and 12.0 kw. Principle Solutronic s SOLPLUS inverters are transformerless, three-phase, grid-connected, solar inverters. Each phase has its own MPP tracker, so that each MPP tracker can be assigned individually. This in turn enables the inverters to be used in installations in which the modules are installed on differently pitched roofs. Grid monitoring Monitoring of the grid is performed by monitoring the phases connected, even in the case of installations with a nominal AC power rating <30kW. In the event of unfavourable circumstances, utility companies must be able to reduce the output of installations with a nominal AC power rating >30 kw. This is done by means of the master-slave network and a SOLCOMBOX with Power Reduction Card. Approvals/certifications See data sheet Languages All language versions offered by Solutronic are integrated in every inverter. You set the language you want by means of a selection menu. Enclosure The enclosure of the inverters is compact. Thanks to their high level of efficiency, the inverters are cooled solely by means of their heat sink. The enclosure fulfils IP 65 and all connectors also comply with this degree of protection when plugged in. To ensure this level of protection, suitable dummy plugs (included in delivery) must be fitted if DC connections are not used. We also supply suitable mating connectors as an option for making an IP 65-compliant Ethernet connection. Selecting DC connectors To make it easier to connect the inverters to the connections on the solar modules, we currently offer two different DC connectors options: Tyco and Lumberg 4 (compatible with MC4). All inver-

Installation instructions During the development and design phases, importance was attached to keeping the enclosure lightweight in order to make it easier to handle. The actual inverter weighs 40 kg, far less than other inverters of the same power rating. For safety reasons, we recommend installation be carried out by two people. The inverter is mounted to the wall with the aid of a bracket, which should be mounted to the wall first, to simplify installation of the inverter. The inverters can be mounted without having to ensure a minimum lateral clearance between them and other inverters because they are cooled by downward convection from top to bottom. However, we still recommend a clearance of 15 cm on either side of each unit in order to make servicing the inverter installation easier. Software updates Software updates can be loaded either on site or remotely using our SOLPLUS+ software. How to order All inverters are supplied with a Setup menu that enables you to select your language and set country-specific grid codes.

30 Com munication and installation monitoring SOLCOMBOX More information can be found on our download page at The SOLCOMBOX is an accessory that has been designed specifically for use with SOLPLUS inverters. If performs a number of different function depending on the hardware option cards installed in the box. 1. Sensor connection and energy management In its standard form, the SOL- COMBOX facilitates the connection of sensors and the integration of energy management solutions by means of relays and digital outputs. 2. Communication and other RS485 ports SOLCOMBOX (delivery contains nontransparent enclosure) GSM or analogue modem cards can be installed directly in the SOLCOMBOX to enable the data of PV installations that cannot be retrieved via the internet (TCP/IP) to be still be retrieved remotely. If you also wish to install other methods of data retrieval, such as a large display on which to visualise the data, an additional option card with a RS485 port is also available. 3. Grid and infeed management requirements Power reduction The power reduction functionality of the system is controlled by the power utility. The PRC (Power Reduction Card) option card is then responsible for forwarding the power reduction command to all of the inverters of the installation (so far as they are networked) by means of ripple-control signals. Controlling the cos phi value The cos phi option card is used to control the cos phi value of the installation in accordance with analogue values specified by the power utility. Controlling the Q value The Q/100V option card enables the Q value to be controlled by means of a 100 V tap at the transformer. Transferring the installation s output values The analogue values option (4 20 ma) allows the output values of up to 32 inverters connected to the installation to be transferred to the power utility by the SOLCOMBOX. Installation instructions The SOLCOMBOX is available with degree of protection IP65, i.e. dust-tight and protected against power water jets. It should be installed close to the inverters and terminate the master-slave network of the installation. Connections An M12 connector is attached to the SOLCOMBOX for connecting the inverters. Two thread glands are provided for running the connecting cables of the option cards installed out of the SOLCOMBOX s enclosure. These can also be used to run a standard-assembled patch cable into the unit. If your power utility have specific requirements with regard to grid and infeed management, please contact our Service team. We will gladly examine the feasibility and practicability of these demands and draw up an offer tailored to your and your utility s requirements. 28 USB/RS232 adapter USB/RS232 adapter for reading out the data of an inverter connected to the RS232 port via the USB port of the PC.

32 Yield monitoring with master-slave networking More information can be found on our download page at 30 This is a software-controlled monitoring feature that is built into every SOLPLUS inverter. Depending on the type of system and the functions you want to use, the use of these functions necessitates the setting-up of a master-slave data network and setting of the network s parameters. The yield monitoring function is based on the comparison of yield data from an installation comprising at least two inverters that are networked by means of their RS485 ports. Requirements All inverters must have the same firmware version installed. The PV generators connected to the individual inverters of the installation must be as homogeneous as possible, i.e. not or only minimally positioned in the shadow of a building, tree or the like, have basically the same geographical orientation, the same roof pitch and degree of back ventilation, and comprise the same modules or cell types. Differences in one or more of these criteria can lead to the tolerable variation in yield having to be set to a relatively high value, which would mean that real deficits in yield would no longer be able to be reliably detected. Additional information would then have to be evaluated. Setting of the master-slave data network The master-slave data network must be set up using the RS485 cabling, and an inverter selected as and configured as the master inverter. How it works The nominal DC output of the PV modules connected to each inverter in the installation must be entered and a communication master defined. The master inverter then collects the data of the slave inverters in the network, compares them and outputs an alarm if necessary. Alarms If the master inverter detects a yield variation, it continues to function but immediately outputs an alarm both visually and acoustically. The serial number of the slave concerned is then displayed in the basic (start) screen. Our SOLPLUS+ program allows you to make a graphical comparison of the yields of the individual inverters. If you do have and enter the activation code, an automatic check takes place and an alarm is output if necessary. You can request the code from Solutronic. Automated handling and forwarding of yield alarms from the inverter is possible via SOLPLUS+ Professional and SOLVOLT. Installation instructions The master-slave data network is set up using the RS485 port each SOLPLUS inverter is fitted with as standard. Depending on the type of inverter, different hardware solutions are used to make the connections. The connection accessories required are listed in the documentation that accompanies each inverter.

33 Yield monitoring with the aid of the Sensor box Sensor box Technical Data Input 0 5 V via port to inverter Mechanical system Operating conditions -20 to +70 C Degree of protection IP 65 Dimensions Weight 145 x 83 x 39 mm approx kg This is a software-controlled monitoring feature that is built into every SOLPLUS inverter. The yield monitoring function is based on the comparison of yield data from a single inverter or of the yield data of a master inverter of a system in the master-slave network and a module-temperature and insolation sensor connected. This sensor can be connected directly to SOLPLUS inverters but has to be connected to SOLPLUS S-series, SOLPLUS 2P-series, SOLPLUS inverters via the SOLCOMBOX. Requirements Suitable installation position and geographical orientation for the sensor box (same inclination, orientation and shadowing as the modules) Configuring the inverter Configuring the inverter involves entering the module efficiency, the surface area of the PV modules connected, the module temperature coefficient and the number of days. These pieces of data are then used to determine as of when an alarm is to triggered. Owing to the different design and the cell type of the sensor, it may be necessary in the initial phase of use to calibrate by adjusting the parameters. How it works The inverter records the day yield of the sensor for every day of the year. This memory is cyclical, i.e. after a year, it overwrites the old values stored. By comparing the sensor with the yield of the inverter, you can detect variations and errors, such as module failures, string failures, shadowing or soiling. Alarms If the inverter detects a yield variation, it continues to function but immediately outputs an alarm both visually and acoustically. The cause of the alarm is displayed in the basic (start) screen. Our SOLPLUS+ program allows you to make a graphical comparison of the yields of the individual inverters even if you do not have the activation code. If you do have and enter the activation code (which you can request from Solutronic), an internal check takes place and an alarm is output via the inverter. It is not at present possible to remotely transfer the alarm. Automated handling and forwarding of yield alarms from the inverter is possible via SOLPLUS+ Professional and SOLVOLT. How to order Mounting and installation instructions of the sensor box Please follow the mounting instructions included with the box. There are two different methods of connecting the sensor to the inverter or SOLCOMBOX: - plug connector for 25-pin D-SUB, with soldering cups and housings - adapter with elbow plug (max. height 25 mm) to fit the connections to the inverter Depending on the connector option you want, please order the sensor box as follows: Connector variant Order reference Sensor box with connector for soldering: SB-SUBD Sensor box with connector for clipping on: SB-KL 31 Subject to change without notice. Errors excepted.

34 SOLPLUS+ basic functions and Comfort version More information can be found on our download page at 32 SOLPLUS+ is the communication program for evaluating, receiving and transmitting data output by the SOLPLUS family of solar inverters. Its user-friendly GUI lets you monitor all kinds of PV installation quickly and easily. Not only the entire contents of the yield memory but those of the data logger, too, can be displayed graphically. SOLPLUS+ also allows you to configure all relevant inverter settings in the same way as you can via the display. SOLPLUS+ can be adapted to the requirements of the various types of user group. And it goes without saying that SOLPLUS+ integrates all the special functions SOLPLUS inverters have to offer. Evaluation of a sensor integrated into the system can be displayed graphically, as too can ownenergy consumption as recorded by the Pulse-meter connected. The program can be used to retrieve data from installations that are connected directly by means of a RS232 (serial connection with USB SOLCOMBOX adapter), a RS485 data network, modem (analogue or GSM) or Ethernet (TCP/IP). Solutronic recommends remote retrieval of inverter data via TCP/IP. Thanks to the Ethernet port built into all our inverters as a standard you have the ability to read out the data directly or over the Internet. SOLPLUS+ Depending on what the customer wants to use the software for, Solutronic offers three different versions of SOLPLUS+. PV module PV module PV module SOLPLUS 50 RS485 SOLPLUS 120 RS232 GSMI/GSME AMOI (Analogue modem) Telephone line GSM SOLPLUS 50 RS232 RS232 RS232 TCP/IP TCP/IP TCP/IP TCP/IP Network cable Mobile phone RS485 SOLVOLT W-LAN Network cable Internet Router PC: PC SOLPLUS Modem Network cable 1. SOLPLUS+: The basic functions The free version of SOLPLUS+ offers end customers a quick overview of their installation. You configure your PV installation on the administration page just the once after installing the program, and all information stored and data retrieved are saved ready for access whenever you want. You initiate reading-out of you system s data when and how you want. Yield monitoring The yield monitoring function of the program gives you a quick overview of the yield figures, displaying the yield of the entire installation or those of each individual inverter in the form of bar charts. Yield logger information is saved to an endless-loop ring memory and kept stored in the inverter over a full 12 months. As a result, it would in principle be sufficient to call up the yield data just once a year in order to save and archive it. Data logger Customers can select up to 8 parameters they want the data logger to record. The data logger window allows you to choose which data from which SOLPLUS inverters are to be displayed. By opening additional, new windows, you can also compare inverters at a glance. Graphic functions It goes without saying that SOLPLUS+ incorporates all commonly available graphics functions. Data logger charts can be displayed as line or scatter diagrams. Zoom functions enable you to study details. Every graphic can be exported and printed out.

35 Enhanced yield monitoring This is performed by means of visualising specific yields in the master-slave network or by means of a sensor. By comparing the specific sensor yield with the actual yield of the entire installation, you are able to detect long-term module, installation and shadowing problems. Exporting service data This function enables you to send all installation data to Solutronic or your dealer for servicing purposes. Software update With the exception of SOLPLUS inverters, all units can be updated with the latest firmware version simply and conveniently via the Administration page of SOLPLUS+.

37 SOLVOLT The SOLVOLT Web Portal SOLVOLT is a web portal that enables you, the user, to access your PV installation from anywhere and at any time, and to read out the very latest data stored. Solutronic recommends SOLVOLT as an intelligent way to monitor small and medium-sized installations. Any subsequent detailed fault analysis and diagnosis can be carried out using the graphical evaluation program SOLPLUS+. Requirements To be able to use and access your data via SOLVOLT, your PV installations must either be connected to the internet using the TCP/IP protocol or be equipped with a GSM or analogue modem. The data of installations located outside Germany can only be accessed via SOLVOLT using a TCP/IP connection. We strongly recommend connection via the internet for all installations, including those in Germany, because it enables you to read out the data of an unlimited number of inverters both quickly and cheaply. To this end, we have built an Ethernet port into all our inverters as a standard feature. Registration Once you have registered your installation with Solutronic, we then download the data of the installation directly onto a server of our own and send the yield data of each individual inverter, the entire installation and the sensor to the SOLVOLT web portal. Display The data are then used to generate graphics in SOLVOLT, with a range of different views (overall view, detail view of inverters) and data-recording time windows from which to choose. All yield data are also displayed in the form of a table and can on request be exported for use in other applications. Function SOLVOLT lets you quickly monitor the yield data of the entire installation and each individual inverter. In the case of installations with several inverters, Solutronic recommends that you enter the nominal DC power connected to each inverter. By doing so, you allow SOLVOLT to display the final yield at the click of a button, enabling module/system problems or potential shadowing problems to be picked up on and analysed quickly. If the installation is equipped with a sensor, SOLVOLT can provide a quick comparison of the yield calculated by the sensor with those of the installation or individual inverters. This sensor, which is specifically customised to match your particular installation, gives you an independent reference source that enables you to analyse and monitor the installation s output over a longer period. Yield and warning s You can set SOLVOLT up to send you yield and/or warning s: Yield s are a daily status report that contains information on how much energy your installation is generating (from today/yesterday up to the point of data retrieval). A warning is only sent if there are no yield data stored for an inverter or the final yield deviates from the desired value set. What will SOLVOLT cost you? We will charge you a one-off installation fee per installation. Once you have paid this fee, you can then access SOLVOLT and retrieve the data of installations with an installed DC output of up to 12 kw for free as long as you do so via the internet (TCP/IP). If you are operating installations larger than 12 kw, there will be an additional monthly charge that depends on the installed capacity and the communications route (TCP/IP or modem) you use. For more information, please contact our Service Team. 35 SOLVOLT table with yield data SOLVOLT user interface Subject to change without notice. Errors excepted.

38 SOLPLANT SOLPLANT is a dimensioning tool for planning and configuring solar plants equipped with Solutronic inverters. Unlike its predecessor, DIMENSOL, SOLPLANT can be used not only to configure individual inverters but also to plan complete installations. Easy to use and adapt SOLPLANT is easy to personalise and to make more effective as an additional advertising medium by adding a company logo. The ability to save and retrieve projects also simplifies the task of managing several large-scale installations simultaneously. Saved data The data of all SOLPLUS inverters are already built into SOLPLANT and can be called up directly. The program can also be used to configure the SOL- Energymanager. The module data can be updated on a quarterly basis simply by downloading them from Solutronic s website. And it goes without saying that you can also add additional modules yourself whenever you want. Configuring and planning When you enter the number of modules to be installed in the PV system, the program automatically runs through a range of possible inverter configurations and shows them on the screen. Based on the location data entered, the tool then checks the MPP voltage limits, opencircuit voltage, the generator current and its voltage against the modules selected, as part of the dimensioning process. You can then choose which system configuration best suits the PV installation to be built. All the technical parameters of the various configurations possible are displayed in the program to give you all the information you need to make your decision. When you actually choose the configuration you want, the tool immediately calculates the cable losses. A final, easy-to-understand printout to present to the customer contains all the figures and dimensions. Currently being planned We are currently planning adding a single-inverter dimensioning function and integrating our communications accessories into a total-installation planning tool. 36 SOLPLANT Homepage View: Module Selection

39 Communication and network accessories More information can be found on our download page at All SOLPLUS inverters are equipped with an Ethernet port that enables their data to be read out in two different ways. Web server: Each inverter is equipped with a web server that provides the user with simple HTML pages with no graphics. The data of each individual inverter can be retrieved remotely from anywhere in the world using a browser installed on a PC. All that is required for the inverters to be appropriately parameterised. Files can be downloaded and settings configured. However, it is not possible to evaluate the data and display the results in the form of graphics. Data retrieval using SOLPLUS+: The communication program, SOLPLUS+, lets you retrieve, that is, read out, the data of inverters that are connected to the network via their Ethernet port. SOLPLUS+ evaluates and displays this data in the form of graphics and provides a fast and convenient overview of the yields generated by the installation. Inverters whose data are to be capable of being read out via their Ethernet port (TCP/IP) must be parameterised and integrated in the network. You can choose either to assign a unique IP address to each inverter or use a router or UMTS router to integrate each inverter in the network. Another option is to set up a master-slave data network in which only the master is integrated in the network. accessories. As part of our service package, you can order the communication accessories for your installation from Solutronic, together with the inverters. We would like to point out that we offer commercially available equipment you can also procure yourself. The samples illustrated are examples. The equipment we supply may differ with regard to its exact appearance and colour. Remote Support Solutronic will shortly be launching a secure VPN connection via the internet, through which we will be able to offer you even better remote support. This service will be available via cable or wireless (GPRS/UMTS) connections. It will bring the following advantages: Reduced costs Faster data retrieval Coordination to the size of the PV installation Secure connection via a VPN tunnel Multiple use accounts possible per customer Multiple installations accessible from one use account Updating of portal data (SOLVOLT) several times a day If you want to take advantage of the added benefits of this tailor-made remote support solution, please send an to: service@solutronic.de Patch cable For making an RS485 connection for SOLPLUS inverters equipped with patch adapters and for integrating all inverters.

40 DE-ICING BOX More information can be found on our download page at Snow sliding off PV module 38 The DE-ICING BOX is an accessory specifically designed for use with SOLPLUS inverters that enables your PV system to operate in reverse. The DE-ICING BOX starts the inverter and switches the inverter to feedback mode. The actual process of converting the energy (from AC drawn from the grid to DC in the PV generator) takes place in the inverter. This functionality of SOLPLUS inverters is used to heat up the PV modules so that the snow begins to melt and slides off. Afterwards, the PV generator can resume normal operation feeding into the grid. How it works The level of energy fed back into the grid is controlled by means of the software to match the inverter connected and as a factor of the voltage and current levels. The polarity (i.e. positive and negative) of the modules remains unchanged in DE-ICING mode. It should be pointed out that the load on the solar generator that arises when it is being heated is equivalent to the load during grid-feed mode, because the generator, i.e. the modules, is also heated up by the energy being generated and output. Owing to the fact that each solar cell is actually a largearea semiconductor diode, the maximum load to which they are subjected during reverse operation is their own rated current. We recommend that you set the current level to just 80% of the generator s rated current because this is the level of current that also flows when the generator is operating at no load under normal insolation conditions. Under standard test conditions (STC), too, the entire rated current generated by the photo-electric effect of a cell discharges via the cell s own diode path. This means that the total load of a reverse flow generated by the inverter in DE-ICING mode is at most equal to the load on the module during periods of insolation and no load. It goes without saying that any solar cell at no load is capable of withstanding this load, irrespective of the manufacturer or the technology employed. Please read our warranty conditions, which are valid only as long as this mode of operation is complied with. If you have any doubts with regard to the compatibility of the DE-ICING BOX with your PV installation, please contact the manufacturer of your modules. Reverse operation in order to use the generator as a heating surface is a permissible mode of application for the generator. The DE-ICING function is only suitable for crystalline PV modules whose open-circuit voltage is less than 750 V at -10 C, because otherwise the full heating performance will not be obtained. The reason for this is that the maximum possible DC heating voltage is 835 V (for SOLPLUS 25 55) or 850 V (for SOLPLUS 60/80 2P and SOLPLUS ) and the PV modules require a higher voltage in feedback mode. You can expect the modules to heat up by approx. 10 C.

41 Recommendations for use Whether all of the snow slides off the modules or not depends on the design (e.g. the pitch) of the roof, how the modules are installed and the ambient temperature. Roof pitch To facilitate optimum functioning of the DE-ICING BOX, we recommend a roof pitch of at least 25 degrees or more. Roof area Prerequisite for use of the DE-ICING BOX is that the area below the solar modules is free of obstructions so that the snow can slide off unhindered. Safety Owing to the fact that the DE-ICING BOX, when in use, leads to snow sliding off the PV modules and the roof, safety is a top priority in the area below the edge of the roof. We recommend you fence off the danger area in some manner. Owing to the way it operates, an activated DE-ICING BOX consumes up to 100 W of power (depending on your PV generator) if the inverter has not yet been switched to de-icing mode. Always switch the DE-ICING BOX off when it is not required: The de-icing function can only fulfil its purpose if its use is carefully thought through and planned. For this reason, we recommend that you keep a detailed log of when and how you use it and of the results achieved (especially during the first winter period). 39 Subject to change without notice.

44 Energy management with SOLPLUS Inverters SOLPLUS inverters offer a costeffective solution to metering and controlling in-house consumption. There s no need for extra, elaborate, external equipment if you ve installed SOLPLUS inverters: In the case of SOLPLUS inverters, the energy management system is connected directly to the inverters. With all other models of SOLPLUS inverter, the energy management system must be connected via a SOLCOMBOX.

45 Optimum utilisation of one s self-generated electricity is based on three equally important components: 1. Metering in-house consumption Before a household can control its own consumption in a responsible way, i.e. manage its energy usage, the individual consumption behaviour of the household in which the energy management system is to be employed has to be determined first. The energy consumption of a household depends on the electrical equipment and appliances in use, how many of them there are and the habits of the people who belong to the household. In-house consumption is metered by installing an inexpensive impulse meter in the meter box and connecting it up to one of the inverters of the photovoltaic system. In the case of SOLPLUS inverters, the meter is connected directly to the inverters, whereas a SOLCOMBOX needs to be interconnected when connecting to SOLPLUS S series, SOLPLUS 2P series, SOLPLUS inverters. Electricity consumption is evaluated using Solutronic s analysis tool, SOL- PLUS+. SOLPLUS+ helps you identify power saving potentials (power wasters). 2. Comparison in-house consumption vs. PV output The share of self-generated electricity consumed in-house and that not used by yourself can only be calculated by comparing your consumption figure with the amount of power your PV installation has generated. SOLPLUS+ helps you change your consumption behaviour, for instance, by installing timers for your electronic equipment. 3. Controlling the electrical consumers via the inverter Each SOLPLUS inverter or SOLCOMBOX can have 2 relays and 2 digital outputs connected to it. If relays are used, the inverter is connected to the consumers by interconnecting either a 1 3-phase contactor or a plug-in power socket switch, depending on the type of the consumer. If digital outputs are used to make the connection, the consumers are controlled by an interconnected electronic load cut-off relay. The appliances can be connected to the inverter by means of a cable connection (current- or signal-carrying). Alternatively, we also offer a wireless solution in which a transmitter connected to the inverter sends the signals output via the relay to a receiver connected to the appliance. If longer distances need to be bridged, we can also supply you with a wireless repeater that amplifies the radio signal. This wireless solution can only be used with appliances that are controlled via the relay. Configuration options Electrical consumers can be controlled in accordance with various principles and by means of simple ON/OFF control: Activation of a consumer at a preset time and for a fixed duration. Activation of a consumer as of a preset PV output and with a specified output-dependent deactivation threshold. Activation of a consumer as of a preset PV output level, but at the latest at a preset time and for a fixed minimum duration. Activation of a consumer as of a preset temperature threshold and/or as a factor of the installation s power output level, for a preset duration or with a temperature-dependent deactivation threshold. Configuring the electrical consumers via the inverter using SOLPLUS+ Our SOLPLUS+ software enables you not only to display your own power consumption in the form of charts, but also to configure the relays and digital outputs of the inverters or the SOLCOMBOX, respectively. 43 SOLPLUS+: in-house consumption and PV output SOLPLUS+: Relais and appliance configuration for in-house consumption management and monitoring Subject to change without notice.

46 SOL-Energymanager More information can be found on our download page at Terminal box for fuses and service connections Touchdisplay Battery inverter Energy management control unit Solar inverter (behind cover) Battery SOL-Energymanager 44 One of the challenges faced in the effort to expand the use of renewable energy sources is to find a solution to the problem of decentralised storage and intelligent management of solar energy. The energy generated by the photovoltaic modules on the roof also needs to be available at times when the sun isn t providing the energy required to generate electricity. This is where the SOL-Energymanager comes in a mini solar power plant comprising a PV inverter, battery inverter, energy management system and Li-ion battery. The purpose of the SOL-Energymanager is to source as little electricity from the grid as possible and to maximise the amount of self-generated power consumed. It s designed and configured to give the end customer maximum economy. Customers are supplied with a compact, single-unit system. No complex, standalone pieces of equipment are necessary. The unit is ready to use immediately after installation. The system is connected to the electricity system of the building by means of a meter box integrated into the cabinet, and it manages in-house consumption fully automatically. There s no need for the owner to carry out any manual adjustments. Energy flow directions Viewed in its pure form, energy flows in different directions in the SOL-Energymanager system. PV electrical consumers: the PV current supplies the electrical consumers directly. PV grid: the energy generated by the solar generator is fed into the grid. PV battery: the energy generated by the solar generator is fed to the battery. Battery electrical consumers: the consumers are supplied with power from the battery. Grid electrical consumers: the consumers are supplied with power from the grid. Battery grid: the battery feeds energy into the grid.* Grid battery: energy from the grid is used to charge the battery.* * Owing to our goal of achieving optimum usage of selfgenerated power, these energy flow directions are currently not provided for. In reality, it s more of a mixture of these modes, depending on the direction selected for the flow of energy and the availability and amount of electricity required in the building. In keeping with the aim of increasing the amount of self-generated energy consumed in-house, the system gives priority to supplying the in-house consumers over feeding power to the grid. If we look at the battery s state of charge, the following statuses are possible depending on the size of the consumer and the level of insolation: Battery fully charged: Power goes to the consumers Excess power is fed into the grid Battery not fully charged: (depending on the level of insolation) Power goes to the consumers Excess power is fed to the battery Subject to change without notice. Errors excepted.

47 Battery efficiency and capacity utilisation The efficiency of the battery depends on the battery s own internal resistance. This is influenced not only by the state of charge and state of health of the battery, but also by its temperature.to optimise the battery s efficiency and its longevity, it s utilised to max. 80% of its charge capacity and its power output (for supplying the electrical consumers) is limited to max W. Outputs higher than 1500 W are always supplemented by drawing power from the mains. In this way, we achieve battery charging efficiency (charging and discharging) of 97% (including cell losses and contact resistance). System efficiency = nighttime efficiency The energy generated by the solar generator is fed to the battery during the day and then transferred to the power system or to the electrical consumers, later (during the night). In this system, the DC/DC converter of the solar inverter achieves up to 99% efficiency. The solar inverter itself is up to 98% efficient. The electrically isolated battery DC/DC converter reaches peak efficiency figures of up to 98%. All in all, the full storage process (from the PV generator to the battery and into the grid) chalks up an overall nighttime efficiency rating of 90%. To further optimise the system as a whole, care has been taken when designing the enclosure to ensure that the waste heat from the battery does not dissipate in the direction of the inverters, so that they remain as cool as possible. Moreover, the SOL-Energymanager also achieves excellent levels of efficiency at the low end of its output range when providing electricity at night, even though it has to operate below its rated output point. The SOL-Energymanger is based on the system of a central, intermediate DC link. This offers the following advantages: a compact unit thanks to a compact enclosure (weight/size) a central control unit no need for a redundant DC/AC inverter maximum efficiency PV inverter controller String 1 AFI Inverter (SP 40 S2E) Production meter Existing electrical installation of building String 2 DC circuit breaker DC/DC converter controller DC/DC converter Connection for additional inverters Local visualisation & control Power meter Emergency power relay 45 Purchasedenergy meter and export meter Grid Li-ion modules Appliance controller Building automation interface Ethernet

48 SOL-Energymanager Battery size and design The SOL-Energymanager is a system designed specifically for households with an annual electricity consumption of up to 6000 kwh. Panels with a combined maximum DC output of 4800 W can be connected to the solar inverter that comes with the system, which means even small roofs are suitable. The design target when dimensioning the battery storage capacity (taking into account annual consumption) is to see between 70 and 90% of self-generated electricity consumed during the months from spring to autumn. At wintertime, the battery principally serves to cover daytime power consumption. The battery can, however, also be used as a kind of night storage power supply, being charged with off-peak electricity for use during the next day.* The size of battery required to provide the maximum possible in-house consumption depends on the household s load profile: at what times of day are the inhabitants at home, what electrical loads are in use and whether they can be controlled, and how high the annual power consumption is. The bar chart (fig. 1) shows how to calculate the size of battery required for three different types of consumer, based on their annual consumption. These calculations were made on the assumption that the battery holds it charge throughout the night in spring and autumn. Provided there is a certain level of daily consumption (that matches the insolation profile), a 5.4 kwh battery fits the bill in the majority of cases which is the size supplied with the standard configuration of the system. We will be offering an optional addon comprising additional storage modules, each with a capacity of 1.8 kwh. Communication concept The various components that make up the SOL-Energymanager system communicate with each other via serial ports. Customers can read out all the relevant data regarding insolation, in-house consumption and battery charge level on the integral touchscreen. And if the SOL-Energymanager is connected to the internet, its data can also be accessed remotely using a PC and the Web Portal.
