The Fronius Energy Cell
Ensuring a year-round autonomous energy supply involving photovoltaics was previously only possible by having environmentally-damaging diesel generators to fall back on. Fronius has found a new solution - the Fronius Energy Cell. In future, the energy cell can be used to convert excess energy into hydrogen for storage, converting it back into useful power when needed.
Please note that the Fronius Energy Cell is not yet certified according to UL.
