Abstract: This paper proposes a novel grid-connected SAF/PV-H 2 topology in which a single three-phase multifunctional inverter simultaneously provides renewable power interfacing, energy storage integration and shunt active filtering. The system integrates a photovoltaic array, proton exchange membrane electrolyser, hydrogen storage tank, and proton exchange membrane fuel cell on a common DC bus for coordinated energy conversion, hydrogen production, storage, and reconversion. An extended instantaneous p-q-theory-based current identification method, combined with DC-link voltage regulation, is developed to achieve harmonic compensation, near-sinusoidal source currents, and stable DC-bus operation. A rule-based energy management strategy supervises power flow according to photovoltaic generation, load demand, and hydrogen storage level. MATLAB/Simulink/Simscape Electrical simulations under representative operating conditions demonstrate effective DC-link regulation around 800 V, appropriate surplus PV utilisation for green hydrogen production, fuel-cell support during low-irradiance periods and THD v and THD i reduction from about 1.3% to 26.01% to about 0.14% and 1.99% respectively satisfying IEEE 519 limits.
