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
