Intended Use

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.

Only use gensets in conjunction with the Fuel Save Controller which fulfill the reverse power limits of the
Fuel Save Controller (see Section 11 "Technical Data", page 51).
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 with SMA Solar Technology AG (see technical information
"Gensets in PV Diesel Hybrid Systems with SMA Fuel Save Controller 2.0").
The current and voltage measuring of the SMA Fuel Save Controller is designed for four-conductor utility grids with
three line conductors and one neutral conductor as well as for three-conductor utility grids with three line conductors. If
another grid type is used, the connection of the current transformers must be coordinated with SMA Solar Technology
AG.
The SMA Fuel Save Controller has a Modbus/TCP interface for communicating with peripheral devices. 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 product is suitable for indoor and outdoor use.
Use this product only in accordance with the information provided in the enclosed documentation and with the locally
applicable standards and directives. Any other application may cause personal injury or property damage.
