11 SMA Solar Technology AG 3 Product Overview 3 Product Overview 3.1 Functions Together with SMA inverters, the Fuel Save Controller is a system solution for the installation of PV diesel hybrid systems through the integration of PV power plants into local utility grids based on gensets. The Fuel Save Controller continuously monitors the power output of the SMA inverters as well as the operating state of the gensets and loads. On this basis, the SMA Fuel Save Controller controls the SMA inverters and adjusts its output power, where necessary. This will ensure a stabile operation of the PV diesel hybrid system. SCADA AC Data transmission Internet Modbus TCP Measurement SENSOREN FUEL SAVE CONTROLLER DATA ACQUISITION MODULE SUNNY CENTRAL STORAGE * SMA PV INVERTER WITH PV ARRAY GENSETS UTILITY GRID (OPTIONAL) LOADS Figure 1: Regulation principle of PV systems with Fuel Save Controller The Fuel Save Controller performs the following tasks: Monitoring the power and operating state of the gensets Monitoring the loads and state of the local grid Calculating suitable s for the maximum power of the inverters according to defined parameter settings and the current status of gensets and loads Control and communication interface to the inverters Internal logging of all relevant system data (e.g. for local and remote monitoring) Emergency shutdown of the PV inverters under fault conditions in the PV diesel hybrid system The basic configuration enables communication with one higher-level genset control system and inverters of the Sunny Tripower and Sunny Central CP series. Further devices (e.g. inverters of the Sunny Central Storage series) can be installed in consultation with SMA Solar Technology AG. To ensure system stability at all times, the Fuel Save Controller uses Modbus/TCP or CAN to monitor whether the gensets are connected to the local utility grid and what level of active power and reactive power the gensets are feeding into the grid. The Fuel Save Controller is equipped with a Modbus/TCP interface for local and remote monitoring as well as for the communication with peripheral devices. Depending on the configuration, it is possible to communicate with the following peripheral devices: A higher-level control system with up to eight gensets User Manual FSC20-BA-en-22 11

12 3 Product Overview SMA Solar Technology AG Controllers for up to eight gensets The power management and the communication interface of the gensets must be compatible with the Fuel Save Controller for optimal operation of the PV diesel hybrid system. Therefore, the combined use of the Fuel Save Controller and the gensets must be coordinated withsma Solar Technology AG (see technical information "Gensets in PV Diesel Hybrid Systems with SMA Fuel Save Controller 2.0"). up to 64 inverters a remote monitoring system (SCADA or user interface/ftp) The Fuel Save Controller is also equipped with a CAN interface for communicating with up to eight gensets. Ensure that all communication between the Fuel Save Controller and the gensets takes place via either the Modbus/TCP interface or the CAN interface. The Fuel Save Controller is not designed to communicate with gensets via the Modbus/ TCP interface and CAN interface at the same time. In combination with the system specifications defined during commissioning and the data from the load measurements and grid analyses, the Fuel Save Controller calculates power s for active power and reactive power suitable for the inverters. The power s are transmitted as setpoints to the PV inverters. For local and remote monitoring, the Fuel Save Controller logs data on the power and operating state of the inverters and the loads, and the power and operating state of the gensets. The logged data is saved in CSV format for 100 days and can be accessed via the integrated FTP server. The Fuel Save Controller is equipped with up to three internal measurement modules. Each measuring module has one measuring system for voltage measurement and two measuring systems for current measurement. All measuring systems records the measuring s via three conductors. During network analysis, the Fuel Save Controller uses the measured s. Further measuring systems can be implemented via an optional Data Acquisition Module in consultation with SMA Solar Technology AG. During commissioning of the Fuel Save Controller, the user has the possibility to activate various functions for stable and reliable operation such as minimum genset loading and power control range. In addition, it is possible to remotely monitor all relevant measurement data, process data and the current system status by means of SCADA or a webbased interface. 3.2 Structure A B C D Figure 2: Design of the Product Position A Designation Key switch 12 FSC20-BA-en-22 User Manual

The system network can be overloaded due to unauthorized customer communication with the inverters. Control commands of the Fuel Save Controller cannot be sent to the inverter anymore when the system network is overloaded. This may lead to reverse currents and the destruction of gensets. Only operate the system network as documented in the acceptance test during commissioning. The inverter data can only be requested via Fuel Save Controller. Procedure: 1. Configure the system router in such a way that the secure VPN connection is enabled for Service. 2. Make sure that the product-internal router has established an Internet connection. 3. Call Service (see Section 13, page 103). Service will check whether the product-internal router has established a VPN connection. User Manual FSC20-BA-en-22 27

46 7 System Monitoring SMA Solar Technology AG Configuring the Operating Mode NOTICE Damage to the PV inverters, gensets, or loads caused by the input of incorrect setpoints In Manual mode, the setpoints for the PV inverters and the reserve power to be kept by the gensets are specified via the user interface. If the specifications are incorrect, the technical thresholds of the PV inverters, gensets, or loads can be exceeded. An exceeding of technical thresholds can lead to damage of the PV power plant, gensets or loads. For continuous operation of the PV diesel hybrid system, always use the automatic operating mode. Only activate the manual operating mode in temporary and exceptional situations (e.g., when carrying out maintenance). In the operating mode, verify that the technical thresholds for PV inverters, gensets, and loads are being adhered to: For the manual operating mode, at least 2 persons must be present at all times and must be trained in the use of the manual operating mode. Both persons must continuously monitor the adherence to technical thresholds during manual operating mode via the user interface. If the Fuel Save Controller remains five minutes in the operating mode Manual and no user is logged in, the Fuel Save Controller switches automatically to the operating state Standby via the SLOW STOP mode. Requirement: You must be logged in as Installer. Procedure: 1. Choose the menu Plant Overview via the page and menu selection. 2. Choose Operations > Mode via the page and menu selection (see Section "Overview of Operating Modes and Setpoints", page 43). 3. Select the [Activate] button in the Activate automatic mode bar to activate Automatic mode. 4. To activate Manual mode, select the [Activate] button in the Activate manual mode bar. 5. To deactivate Manual mode, activate Automatic mode or select the logout button in the header Specification of Setpoints for PV Power Plant by SCADA System When this function is active, a SCADA (Supervisory Control and Data Acquisition) system specifies the setpoints for the PV power plant and the reserve power to be retained by the gensets. The Fuel Save Controller checks these setpoints. Should the setpoints issued by the SCADA system jeopardize the stability of the PV diesel hybrid system, they will be corrected by the Fuel Save Controller. Finally the setpoints are forwarded to the PV power plant by the Fuel Save Controller. For information on which Modbus registers are supported, see the technical information "SMA Modbus Interface" at For information on which of the supported SMA inverters support the Modbus interface of the Speedwire/Webconnect data module, refer to the datasheet "FSC20_Modbus-DB-en-10.xlsx" at Procedure: 1.

Only give the password for the user group Installer to qualified persons. Change the default passwords as soon as possible. Read the description of the parameters carefully and follow all instructions relating to the settings options of the parameters. NOTICE Destruction of gensets due to insufficient reserve power Once the SMA Fuel Save Controller and PV power plant have stopped, the PV power plant is no longer available as energy supplier. Now only the gensets supply the loads. If the current reserve power of the gensets is insufficient for supplying the power required by the loads, the gensets become overloaded Sustained overload of the gensets can result in failure of the power supply and destruction of the gensets. Prior to stopping the Fuel Save Controller, always check whether the current reserve power of the gensets is sufficient to cover the requirement of the loads. If the current reserve power of the gensets is insufficient, switch off the loads or connect additional gensets. This increases the reserve power of the gensets. If the power management and the communication interface of the genset are not compatible with the Fuel Save Controller, power management must be deactivated on the Fuel Save Controller. In this case, the gensets must be monitored to ensure that sufficient reserve power is retained.
