The world’s largest PV-diesel hybrid power plant with a battery storage system is currently being built in the Bolivian province of Pando. SMA has been not only selected to supply the PV inverters for this project, but also SMA’s Fuel Save Controller, which recently won the Intersolar Award in the PV category. SMA was also selected to provide four newly-developed inverters for large-scale battery storage systems using lithium-ion technology.
The SMA solution for solar diesel hybrid systems, with the Fuel Save Controller as its central component, has been introduced with rave reviews including winning the Intersolar Award in the Photovoltaics category. To learn more what this does, how it works in a PV-diesel hybrid system and what makes it so special, I turned to Product Manager Johannes Weide.
With SMA’s Fuel Save Solution for large industrial applications, PV can be easily and efficiently integrated with diesel generation. The Sunny Tripower and Sunny Central inverters convert direct current from PV modules into alternating current and feed it into power supply systems. The SMA Fuel Save Controller intelligently manages the PV feed-in and diesel genset. The result: an achievement of up to 60 percent of PV-supplied electrical capacity compared to relying solely on an installed genset’s capacity.
Energy-intensive operations in areas with non-existent or poor infrastructure often rely on gensets (diesel generator sets) for their electricity supply. In regions with a sufficiently high level of solar irradiation, the additional integration of photovoltaics in the power supply system can prove worthwhile.
