SolarEdge S440-1GM4MRM PV Inverter

The SolarEdge S440-1GM4MRM is a 440 W SolarEdge S-Series power optimizer designed for residential PV modules, delivering module‑level optimization when paired with a SolarEdge inverter. It supports PV modules up to 440 W and a maximum Isc of 15 A, with SolarEdge’s updated guidance listing a rated input DC power of 490 W for installations after April 1, 2024. The optimizer incorporates a DC‑DC stage to maximize power from each module and communicates with the central inverter to coordinate power across the array, helping improve energy harvest under shading, soiling, or module mismatch. Its output leads are configured with a 2.3 m positive lead and a 0.1 m negative lead to connect to the SolarEdge system in typical residential rooftop installations. As part of the S-Series, the S440-1GM4MRM is intended for residential deployments and is designed to work with SolarEdge inverters that support module‑level optimization, with compatibility considerations that include solutions for higher‑power modules and, in appropriate configurations, bifacial modules. This compact optimizer enables granular monitoring and performance gains at the module level while maintaining the streamlined system architecture SolarEdge is known for.
