PV performance optimization at module level. Specially designed to work with SolarEdge residential inverters.

S-Series power optimizers have an excellent efficiency of 99.5%. The S440-1GM4MRM mitigates all types of module mismatch losses, from manufacturing tolerance to partial shading.

Faster installation with simplified cable routing and easy installation with a single screw.

Detects abnormal PV connector behavior and prevents safety issues. Module-level voltage shutdown for installer and firefighter safety.

The S440-1GM4MRM power optimizer is compatible with bifacial solar modules. It is not allowed to combine S-series and P-series power optimizers in new installations.
