The rapid adoption of photovoltaic (PV) systems has accelerated integration of technologies such as water electrolysis into distributed energy systems. However, the variability of renewables impedes stable operation of PVs. To address this problem, this study proposes PV-battery-inverter-based energy management that provides a highly renewable-based power supply for hydrogen production. The control strategy prioritizes battery charging during high irradiation, then transfers PV and battery energy to the electrolyzer via an inverter and uses the grid as a backup source during low irradiation. Experimental verification over a five-and-a-half-hour operating window confirms that hydrogen is produced using about 97% of PVs, reducing grid dependence to 10 min. A comparative analysis confirms the system's operational stability and high efficiency. Furthermore, a Levelized Cost of Hydrogen (LCOH) analysis of system estimates the hydrogen cost at 22.6 USD/kg. These findings demonstrate technical robustness of the proposed architecture under varying operating conditions and highlight its methodological contribution to PV-driven hydrogen production systems.
