SolarEdge P405-4NM4MRM-NM25 405W Power Optimizer – MC4 – North America

The SolarEdge P405 Power Optimizer is a module-level DC power optimizer designed for use with compatible SolarEdge inverter systems. Rated for photovoltaic modules up to 405 watts, the P405 features a substantially higher input-voltage capability than many standard SolarEdge P-Series optimizers, making it particularly suitable for thin-film and other higher-voltage PV modules.

Installed at the individual solar module, the P405 performs module-level Maximum Power Point Tracking (MPPT), helping maximize energy production and reduce losses caused by shading, module mismatch, soiling, aging, and variations between individual solar panels.
