  • VISION FRONIUS ENERGY CELL

    / The Fronius Energy Cell system concept stores energy which is 100% harvested from solar.

    / 1. Power is generated by photovoltaic modules. Surplus energy is transmitted to the Energy Cell.

    / 2. Hydrogen fuel and oxygen is generated by electrochemical water splitting.

    / 3. Hydrogen fuel is stored and converted back into power and heat on demand.

    / 4. The inverter transforms DC current into AC power.Inverter
