AU battery backed photovoltaic (PV) hydrogen production system shows several advantages over non-battery systems, especially in cases in which the PV array is not totally dedicated to hydrogen production. The use of battery state-of-charge (SOC) and time of the day limits as control parameters to optimize hydrogen production in au battery backed PV-electrolysis system may increase the annual H-2 Production by more than 10%. Through shunt resistor regulation of the electrolyzer current, au high system efficiency may be maintained even if the power of the PV array well exceeds that of the electrolyzer.
