SMA FUEL SAVE CONTROLLER

The SMA Fuel Save Controller (FSC) is a key component of the SMA solution for photovoltaic/ diesel hybrid systems. It allows the use of cost-efficient solar energy to generate power in order to lower fuel consumption from diesel generators. As the interface connecting the diesel generator, the PV system and the load, it manages need-based PV feed-in according to load and generation profiles of the system as a whole. The FSC performs comprehensive grid management functions, ensures maximum operational safety, and minimizes operating expenditure and CO₂ emissions. The second generation of the FSC is available for system sizes of 100 kW to 50 MW. Hybrid systems with SMA technologies offer modular expansion at any time and optimum system control through remote monitoring.

The SMA Fuel Save Controller is available in the following versions: M, L and customized

Tailor-Made

• The modular concept allows system setups where long distances between the PV system and the gensets must be covered
• The PV system can be expanded at any time
• An optional battery-storage system including the Sunny Central Storage battery inverter can be integrated as well
• Both central and string inverters can be used

High Yields

• High PV penetration of up to 75% lowers total energy costs
• An optional storage integration with the Sunny Central Storage battery inverter increases the PV penetration level and reduces the number of must run gensets
• SMA's Technical Consultants support the customer by designing the system for maximum fuel savings

The modular design of the FSC allows for individual adjustments according to project requirements. Please contact your SMA contact person for more information.
