Likewise, a fire in the vicinity of the equipment can cause the storage system to catch fire, releasing the contents of the battery modules. Observe the warnings about the risk of injury/burns due to the escape of electrolyte (see section.5 pg. ). In the event of a fire in the vicinity of the product or in the storage system itself, proceed as follows: Only firefighters with appropriate protective equipment (safety gloves, safety clothing, face guard, breathing protection) are permitted to enter the room where the burning storage system is located. There is a danger of electrocution when extinguishing fire while the storage system is switched on. Therefore, before starting to extinguish the fire: Switch off the storage system. Switch off the mains fuses in the building. If the storage system and/or mains fuses cannot be safely switched off: Observe the minimum distances specified in DIN VDE 0 for the extinguishing agent used. The storage system works with an output voltage of 00 V (AC) and is therefore considered a low-voltage system. A storage system fire can be extinguished using conventional extinguishing agents. Water is recommended as an extinguishing agent in order to cool the battery modules and therefore prevent thermal runaway in battery modules which are still intact. Page 0 of 5

11 Safety Information on the battery modules: The battery modules have a nominal voltage of 5. V (DC) and therefore fall into the range of protected extra-low voltage (under 60 V DC). The battery modules do not contain metallic lithium. Further information can be found in the following document: Merkblatt für Einsatzkräfte Einsatz an stationären Lithium Solarstromspeichern (Information sheet for electricians Use on stationary lithium solar energy storage systems, published by the German Solar Association, or BSW Bundesverband der Solarwirtschaft e.v.). Regulations (directives, laws, standards) Observe all relevant, currently applicable national regulations, especially the following: Regulations of the local power supply companies. This list presents only a selection and does not claim to be exhaustive. The authorised electrician is responsible for knowing and observing all of the regulations relevant to their work..5 Warnings This section contains specific warnings that must always be observed when working with the product. DANGER Danger to life due to electrocution! Touching components inside the storage system poses a danger to life due to electrocution. WARNING CAUTION DANGER Do not touch any components.

16 Product description. Functional description.. Basic principle Figure : sonnenbatterie function 5 6 Public electrical mains Measurement of generation PV system Storage system Measurement of consumption Consumers in the building (e.g. washing machine, hob, lamps, refrigerator, etc.) 6 5 The storage system () constantly measures the current power generation () of the PV system () and the ongoing consumption (5) in the building. Generation > consumption If the generation of power is greater than the consumption, the surplus power (difference between generation and consumption) is stored in the storage system. The battery is charged. For example, if 000 watts are generated and 700 watts are consumed, the battery is charged with a power of 00 watts. Consumption > generation If the consumption is greater than the generation of power, the deficit (difference between consumption and generation) is provided by the storage system. The battery is discharged. For example, if 500 watts are consumed and 000 watts are generated, the battery discharges a power of 500 watts. or of another generator like a wind turbine or district heating plant, for example.

L V A K ex A N Figure 7: Self-consumption switch When the output is activated ( V on terminal 0) the contactor Kex switches and the connected load is powered. The coil connection A of contactor Kex can be joined to terminal 8, 9, 0 or of terminal block X. The maximum current over terminal 0 is 500 ma. Page 8 of 5

49 Electrical connection Connecting combined heat and power unit The connection described here refers solely to a combined heat and power unit (CHP) that produces constant electric power. Modulating generators (with uctuating power) may not be connected in this way. The storage system controls energy flows in the household. If it is to work optimally, the power from a CHP must be registered. For a CHP producing constant power this is possible by terminal, enabling the storage system to determine whether a CHP is momentarily active or not. The power output of the CHP can be entered via display. The entered value is added to momentary generation if the CHP is active. Set the power output of the CHP under Settings-Producer-CHP. Wiring depends on whether or not the CHP has a floating operating contact. CHP with floating operating contact The + Vdc potential can be picked off terminals 5, 6 or 7. +V Figure 8: CHP with operating contact +V U V W PE G Figure 9: CHP without operating contact If the CHP has no floating operating contact, you can connect it as illustrated left. The + Vdc potential can be picked off terminals 5, 6 or 7. A current relay enables you to detect whether the generator is momentarily active. This information can be sent to the storage system by a floating make contact of the current relay. Current relay CHP Page 9 of 5

50 6 Electrical connection 6.6. Connecting heat pump Installation of the two-rate meter must be carried out by the power utility or network operator. A heat pump billed by its own two-rate meter is located in a separate circuit, where control of the storage system cannot consider consumption of the heat pump. The Control heat pump option enables the heat pump to be switched to the circuit of the consumed power meter. Consumption of the heat pump is then registered and considered in control of the storage system. Connect the circuit as in the Figure overleaf. Terminals 8, 9, 0 and are all on GND potential. Join the coil connections A of K0 and K0 to one of these terminals. On the touch screen under Settings-Behavior-Behavior change the button Heat pump operation over battery from No to Yes. Operating principle Contactors K0 and K0 are connected on the outputs of the storage system. Actuating the button Heat pump powered by battery activates output and switches K0, which in turn causes contactor K to pick up. K separates the heat pump from power through the public grid. Approx. 5 seconds after activation of output, output 5 is activated to switch K0, which in turn causes contactor K to pick up. K connects the heat pump to the circuit of the storage system.

52 6 Electrical connection DANGER WARNING CAUTION Notice Connecting PV reduction The PV cutout output of the storage system must not be used if the output power of the PV inverter can be reduced to 0% by PV reduction. The latest PV systems may be subject to feed-in power limitation, e.g. 70% of rated power of the installation at the point where it ties to a grid. There are a variety of measures for this purpose. One measure is reduction of PV power, by communication with the PV inverter across terminal pairs 6/7 and 8/9. Damage to relays K7 and K7 by overload! Only load 6/7 and 8/9 up to a maximum voltage of 50 Vac and current of 6 A. 6 7 K7 8 9 K7 Figure : K7 and K7 Page 5 of 5 Step K7 K7 0 off off on off off on on on Relays K7 and K7 are installed in the storage system, which take different states depending on power limitation. No limitation is necessary in step 0. Both relays have not picked up. If power limitation is necessary, the system changes to step. And if this is inadequate, step is activated, etc.

53 Electrical connection 6 Figure : Connection without and with solar data logger PV inverter Solar data logger You can connect the storage system (X) to the PV inverter () direct (support by the inverter) or by a solar data logger (). The electrician must select which state of the output terminals corresponds to which output power of the inverter, or it depends on the supported values of the inverter. Examples of advisable output power are as follows: Step Output power 0 00 % 60 % 0 % 0% Page 5 of 5

54 6 Electrical connection Connecting PV cutout Cutout of the PV system by a relay (as described here) is unnecessary if the output power of the PV inverter can be reduced to 0% by PV reduction. The advantage of reducing PV generation to 0% compared to cutting out by a contactor is that the PV inverter is ready to operate again faster. The last measure to implement feed-in power limitation is cutout of the PV system by the storage system. For this purpose there is terminal on terminal block X, activated (+ V applied) as soon as cutout of the PV system becomes necessary. PV cutout is through a relay (K in the following diagrams). Coil connection A of the relay is joined to terminal (the maximum current across which is 500 ma). Coil connection A is joined to terminal 8, 9, 0 or (all on GND potential V) of terminal block X. On three-phase PV inverters it is adequate to interrupt a phase conductor to completely cut out the inverter. PV cotout variant In this case relay Kex out the PV inverter directly by separating phase conductor L of the inverter from the public grid.

56 6 Electrical connection DANGER 6.7 Installing the battery modules WARNING Risk of burns! CAUTION The following must be observed when working with the battery modules: Notice Very high short-circuit currents are possible. The battery module is activated when the fuse connector is plugged in. The voltage runs between the plus and minus contacts of the battery module (nominal voltage of battery modules: 5. V DC). The battery module is deactivated when the fuse connector is unplugged. No voltage runs between the plus and minus contacts of the battery module. If all interconnected battery modules are deactivated, it is safe to work on a battery module. When working on the DC circuit: Set aside metal jewellery. Switch off the storage system. Switch off the series fuse. DANGER Remove the orange fuse connectors on all battery modules. WARNING CAUTION Notice Damage to battery modules due to short circuit! If a short circuit occurs when installing the battery modules despite great care to avoid this, proceed as follows: Do not install the affected battery modules under any circumstance. Notify the service team. Page 56 of 5

57 WARNING CAUTION Electrical connection Measuring the battery module voltages Damage to battery modules due to high compensating currents! Notice Differing battery module voltages lead to high compensating currents when the storage system is switched on. Measure the voltages between the internal plus and minus poles of all battery modules (see figure below) and note these down. The battery modules are only allowed to be installed if the maximum deviation between the measured voltages is less than V. If the deviation is greater than V: Notify the service team.

59 Electrical connection DANGER Connecting the DC lines WARNING CAUTION Risk of fire due to high contact resistances and short circuit! Incorrectly connected DC lines can cause a short circuit and thus high heat generation. Improperly connected DC lines can also create high resistance at the point of contact. As very high currents flow through the DC circuit, this high contact resistance can lead to great loss of energy (electrical energy is converted into heat). This can have the following effects: Notice Cable fire: The area around the affected point of contact is heated above permissible temperatures. A fire breaks out and hazardous substances are released. Damage to the battery modules: The high contact resistance generates various high battery module loads. Battery modules may be damaged or destroyed by this. Therefore, proceed as follows: Check all plug connections. Only red lines are allowed to be plugged into red sockets. Only black lines are allowed to be plugged into black sockets. Figure 0: Ensure that all DC lines are Correctly connected (top) and plugged into the sockets all the way. incorrectly connected (bottom) DC line DANGER Danger to life due to electrocution if DC lines are incorrectly connected! Each battery module has a nominal voltage of 5. volts. The battery modules are connected in parallel using the supplied DC lines. The battery modules must never WARNING CAUTION be connected in series, as this could result in life-threatening high voltages from the series connection. The high voltage can also lead to damage/destruction of components. Ensure that all battery modules are connected in parallel, i.e. all plus poles of the battery modules are connected together (red to red). Likewise, ensure that all Notice minus poles of the battery modules are connected together (black to black). Page 59 of 5

60 6 Electrical connection Connect the DC lines as shown in section 5. (pg. 05). Observe the following: Starting from F connect the plus lead to the plus pole of battery module 0.

62 6 Electrical connection Attaching the fuse plugs Prerequisite: All DC lines and BMS communication lines are correctly connected to the battery modules. Attach the fuse plugs on all battery modules. Figure : Attaching the fuse plugs Entering the battery capacity/nominal power on the type plate DANGER Tools: Permanent marker Mark off the correct battery capacity and nominal power on the type plate of WARNING the storage system. The type plate is located on the outside of the storage system. The battery capacity and nominal power can be determined from the technical data (see page ). CAUTION Notice 6.8 Subsequent battery add-on Damage to battery modules through high compensation currents! When the storage system is switched on, diering voltages of the battery modules can lead to high compensation currents. Charge the storage system to 85% before installing newbattery modules. Measure and note the voltages of the individual battery modules before installation. Only install battery modules if the maximum deviation between measured voltages is less than V. New battery modules come with 85% charge. This is why older battery modules must also be charged to this level before installing new ones. Page 6 of 5

63 Electrical connection Full charging of storage system (day before) On a full charge the display of the charge state calibrates. Meaning that after a full charge the displayed charge state corresponds precisely to the actual state. So you should fully charge the storage system on the day before the planned battery extension. On storage systems operated together with a PV system it is best to fully charge at approx. 5:00 h. Normally the storage system will have a high level of charge at this time. So for a manual full charge little energy has to be drawn from the public grid. Proceed as follows to start manual full charging: Navigate to Function page. Press Charge then Auto. You need not fully charge manually if the storage systemwas already fully charged in automatic mode on this day Charge to 85 % Normally the charge drops below 85% during the night. In the morning hours of the day on which you plan to add battery modules the charge has to be increased to 85 %. Proceed as follows: Navigate to Function page. Press Charge, then Standby. Navigate to the start screen to observe the change of charge state. Deactivate charging at 85% (+/- %) by pressing Standby Installing battery modules Shut down the storage system. Install the battery modules as decribed in section 6.7 (pg. 56). Page 6 of 5

As long as the test is not conducted, you see the (i) button on the screen in the top right corner of the start page. Press (i) and you see the message Selftest to run. If the selftest is successful the message disappears. If the selftest was not successful the start screen shows the! button top right. After pressing this button a further window appears in which dierent error messages are shown. These and instructions for correcting the particular error are explained in what follows. The battery modules are minimally charged for the selftest. So conducting the selftest is not possible if: The battery charge is too high. There is no energy from the public grid. In these cases the selftest is conducted as soon as it is possible. 7.. Addressing battery modules The following error message appears if the test detects incorrect addressing: Check battery modules addresses Proceed as follows to correct this error: Shut down storage system. Check the position of the rotary switches on all battery modules. Possible errors: The addressing does not commence with communication address zero. The same communication address is set on more than one battery module. Check termination switch The schedule switch (switch ) must be OFF for all battery modules. Only on the battery module with the highest number must it be ON. The selftest cannot detect all addressing errors. Consequently it is possible for an error to exist but no error message appears. Page 66 of 5

67 Starting up Cabling battery modules Correct cabling is also inspected by the battery conguration test of the DC circuit and the cabling of the BMS communication lines. If the test is not successful, the following messages can appear: Check battery module communication cables and addresses! Check DC cabling of battery modules!

71 Operation 9 9 Operation 9. Operating status The storage system may be in one of the following operating statuses: Standby Charge Discharge Emergency power Off The operating statuses are explained in more detail in what follows. The gures illustrate the energy ow possible and not possible in the particular status. Energy flow possible Energy flow possible 9.. Standby operating status Figure : Standby 9.. Standby keeps the system in a monitoring function. The battery is neither charged nor discharged. On a low charge status there may be brief charging of the battery, however, to prevent exhaustive discharging of the battery modules. Energy may be imported from the public grid to support charging. The remaining energy ow in the household is monitored and controlled. Charge operating status Charge stores electrical energy in the battery. In automatic mode the charging power depends on the available generated surplus and the charge status of the battery. Manual charging uses constant power, possibly also with emergency power. Figure 5: Charge Page 7 of 5

72 9 Operation 9.. Discharge operating status Discharge delivers energy stored in the battery into the home network. The power cannot exceed the consumption required in the household. If the battery is unable to serve the entire home consumption, the remainder comes from the public grid. Figure 6: Discharge 9. Operating mode The storage system controls the energy flow and thus the operating status in the household depending on the activated operating mode. For continuous operation select automatic mode. 9.. Automatic mode In automatic mode the storage system automatically changes to the right operating status. The basis for control in automatic mode is continuous measurement of consumption and generation. If generation exeeds consumption for a certain time, the battery commences charging of free capacity. Depending on the setting the consumer connected by the self-consumption switch is additionally cut in. Also, depending on the setting, the optional wireless socket outlets can be cut in. Once the storage system is fully charged, it changes to standby status. Surplus energy is fed into the public grid. If generation is less than consumption, the battery switches to discharge. This is only an amount needed in the household. Note that necessary switching times of the system can lead to slight controlling delays. Energy management in automatic mode In automatic mode all energy flows are controlled automatically. Depending on generation the storage system switches between charge and discharge. While energy is being generated it is distributed with the following priority:. Consumers in household. Charging of storage system. Feed-in to grid While there is no generation (e.g. nighttime) the consumers in the household are supplied by the storage system up to maximum battery capacity. Extra energy needed is imported from the public grid. Page 7 of 5

73 Operation 9 Automatic connection of consumers Connection of consumers is possibly preferable to feed-in into the grid. This may be a washing machine or a heater for instance. There are two possibilities for automated connection of consumers:. Integrated self-consumption switch. Optional wireless socket outlets 9.. Manual mode Standby As long as Standby is selected manually, the system is in standby status. The storage system is neither charged nor discharged. Floating charging guards against a critical charge status. Select standby to keep the charge status constant. Charge If Charge charge is selected manually, the system is in charge status until the battery is fully charged. Then the system changes to standby or automatic mode, depending on choice. On manual charging the battery is charged with constant current. If generated power is inadequate, additional energy is imported from the public grid. Page 7 of 5

96 Internet access.. Using the graph page The graph page shows all relevant energy flows in a graph. The values displayed are subject to measuring instrument tolerances and rounding errors. The only information that is relevant in terms of your energy bills is the data taken from the utility company's meters. Elements of the power graph The power graph presents the different energy flows in relation to time Clicking on the day, week, month or year button defines the timeframe () shown in the graph. Clicking on the magnifying glass activates or deactivate full-screen mode. The power is shown in watts (W) on the y-axis. The abbreviation k stands for the prefix kilo.,0 k therefore corresponds to,0 kilowatts or watts. Time is shown on the x-axis (in the above example, the timeframe shown on the x-axis is one day). This legend shows which energy flows are displayed in which colour in the graph (consumption is shown in blue, for example). Clicking on the desired energy flow (e.g. consumption) shows or hides this flow in the graph. Clicking on one of the buttons below the graph allows you to navigate to previous or later timeframes Clicking on the button provides the option of printingout the displayed graph. Clicking on the input field to the right of goto allows you to select a date. Clicking on the button > confirms the date selection. Positioning the mouse cursor over the graph shows the exact values for the energy flows at this time. By clicking and dragging, you can select a smaller timeframe in the graph. Page 96 of 5

97 Internet access Analysis of power diagram Given the high density of information, analysis of a power diagram is not too simple. For better understanding, some points in time of a power diagram are analyzed in what follows. Figure 50: Analysis of power diagram It is dark (no generation (yellow)). Consumption (blue) and discharging (red) have the same value. Consumption is therefore covered by the discharging of the storage system. Generation (yellow) is approx. 000 watts. This is used to cover consumption (blue). The intelligent charging management system has postponed charging; the charging buffer is needed to avoid breaching the feed-in limit. The energy that is not required is fed into the grid. Generation has increased to approx. 00 watts. This is used to cover consumption (blue) and charge the storage system (green) at a minimal level. Charging with higher power is prevented by the intelligent charging management system. This function ensures that storage capacity is kept free in order to store part of the midday peak in the storage system later. Consumption (blue) exceeds generation and must be supplemented by the storage system. A breach of the feed-in limit is no longer expected. PV generation covers consumption (blue) and the surplus is stored in the battery (green) so that it will be fully charged by evening. From this point PV generation is no longer sufficient to cover consumption. The difference is discharged from the storage system. The storage system discharge (red) covers total consumption. The storage system is discharged and consumption is covered by usage from the public grid. Page 97 of 5

98 Internet access Analysing pie charts Two pie charts are shown below the power graph. The pie charts always refer to the timeframe shown in the power graph. Generation pie chart Generation, shown in yellow, symbolises the electrical power gained by the generator in the analysed timeframe. The fed-in power is marked in light yellow in the chart. The dark yellow part represents selfconsumption. Self-consumption is the part of the generated power that has not been fedin, but has instead been stored temporarily in the battery or consumed. Consumption pie chart Consumption, shown in blow, symbolised the power that was required in the building during the analysed timeframe. Purchased power (taken from the mains) is marked in light blue in the chart. The dark blue part represents self-production. Self-production is the part of the consumed energy that was not taken from the mains. Page 98 of 5
