The SolarEdge P370-5RM4MRM is a photovoltaic power optimizer designed to maximize the energy output of individual solar modules through advanced module-level MPPT (Maximum Power Point Tracking) technology.

By continuously optimizing the operating point of each panel, the P370 minimizes energy losses caused by partial shading, dirt accumulation, module mismatch, aging, and varying environmental conditions. This allows each module to perform independently, improving the overall efficiency and energy yield of the photovoltaic system.

Designed for use with compatible SolarEdge inverters, the optimizer also enables advanced module-level monitoring, providing detailed performance data for each connected solar panel.

The unit features integrated photovoltaic connectors and a built-in mounting bracket for fast and reliable installation.
