Introducing the New S-Series Power Optimizers for Residential Installations
Who This Product Suits
The SolarEdge S440 is intended for residential and light commercial PV installations using a compatible SolarEdge inverter and modules that fall within the optimizer’s electrical limits. It is suited to installers who need module-level power optimization, monitoring support, and SolarEdge SafeDC functionality. Module, inverter, string-length, and optimizer compatibility should be verified using current SolarEdge design requirements before installation.
Specifications Explained
- 440W rated module power: Designed for compatible PV modules with rated input power up to 440W.
- 60V maximum input voltage: The connected module must remain within the optimizer’s specified DC input-voltage limit.
- 14.5A maximum input current: Module current must be checked against this limit when selecting compatible panels.
- MC4 connectors: This S440-1GM4MRMU variant is supplied with MC4 connectors for compatible PV connections.
- Module-level optimization: Maximum power point tracking is performed individually at each connected module rather than only at the inverter.
- SolarEdge system integration: Designed to operate as part of a compatible SolarEdge optimized inverter system and support module-level monitoring and SafeDC functionality when correctly configured.
System design and installation should follow SolarEdge requirements and applicable NEC provisions, including the requirements relevant to rapid shutdown and PV source-circuit wiring.
