SolarEdge S440 1GM4MRM Solar Power DC Optimizer

The SolarEdge S440-1GM4MRM is a module‑level DC power optimizer from SolarEdge’s S‑series, designed to maximize energy harvest from a single PV module while feeding optimized power into a compatible SolarEdge inverter. It accepts 8–60 VDC input and is intended for PV modules up to 440 Wp (S440), with a PV short-circuit current rating up to 16.5 A and a maximum input current of 15 A. The output cable length is approximately 2.3 meters, enabling flexible string configurations in typical residential rooftops. By delivering per‑panel MPPT and real‑time performance data to the inverter, it helps optimize overall system efficiency and provides module‑level monitoring for maintenance and fault detection. The S440‑1GM4MRM designation identifies this specific variant within the S series, with the article code S440-1GM4MRM, and it is designed for straightforward integration with SolarEdge residential inverters to optimize system performance within the stated voltage and current limits.
