Functions

Together with SMA inverters, the SMA Fuel Save Controller is a system solution for the installation of photovoltaic
diesel hybrid systems through the integration of PV power plants into local utility grids based on gensets. The SMA Fuel
Save Controller monitors and controls the SMA PV inverters and allows stable operation of the photovoltaic diesel
hybrid system. To ensure this, the SMA Fuel Save Controller continuously monitors the operating state of the gensets
and loads and adjusts the output power of the SMA inverters accordingly, where necessary.
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 values 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 photovoltaic 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
• 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 photovoltaic 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 SMA Fuel Save Controller is also equipped with a CAN interface for communicating with up to eight gensets.
Ensure that all communication between the SMA 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 values for active power and reactive power suitable for
the inverters. The power values are transmitted as setpoints to the PV inverters.
For local and remote monitoring, the SMA 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 values via three conductors. During network analysis, the Fuel Save Controller uses the
measured values. Further measuring systems can be implemented via an optional Data Acquisition Module in
consultation with SMA Solar Technology AG.
