Fronius International has achieved a high-efficiency rating for two of its hybrid inverters in the annual Energy Storage Inspection by the University of Applied Sciences in Berlin, Germany.
The European-manufactured Fronius Primo GEN24 6.0 Plus and the Fronius Symo GEN24 10.0 Plus hybrid inverters received an energy efficiency rating of “A” in the 5kW and 10kW categories, respectively.
The annual Energy Storage Inspection compares residential photovoltaic storage systems and provides installers and customers with an independent measure of products on the market.
The 2023 assessment saw 18 energy storage systems from 11 manufacturers receive a System Performance Index (SPI) rating.
High-efficiency systems are indicative of low energy loss, which delivers higher yields and a shorter payback period.
“Fronius GEN24 Plus brings the power of the sun from day into night with the highest degree of efficiency, making best use of available resources,” says Martin Hackl, global director, business unit solar energy, Fronius International.
The Primo GEN24 6.0 Plus, together with the BYD Battery-Box Premium HVS 7.7, achieved an SPI of 92.6 per cent. The Symo GEN24 10.0 Plus with BYD Battery-Box Premium HVS 10.2 produced an SPI of 95.4 per cent.
Fronius International – a family-owned, Austrian-based company with 29GW of installed inverters worldwide – credits its Multi Flow Technology as a major contributor to the hybrid inverters’ high-efficiency rating in the university’s assessment. It enables the intelligent management of energy flows, permits simultaneous current flows in all directions, and AC and DC coupling of battery storage.
