SolarEdge P404 Optimizer (405 W, 1.2 m cables)

The SolarEdge P404 power optimizer is designed for 60-cell and 72-cell modules in short strings, offering input power up to 405 W. The device provides independent monitoring of each module and voltage reduction for safety during installation and in case of fire.

The SolarEdge P404 power optimizer is a device designed to work seamlessly with inverters of the same brand. It maximizes energy yield by reducing losses caused by PV module mismatch or partial shading. The IP68-rated design ensures reliable outdoor operation in a temperature range from -40 to +85 °C. Using optimizers in a PV system can generate up to 25% more energy.
