Who This Product Suits
The SolarEdge S440 is suited to residential and light commercial PV installations designed around compatible SolarEdge inverters and S Series optimizers. It is particularly useful where module-level optimization, monitoring capability, and SolarEdge rapid-shutdown functionality are required. System designers should confirm optimizer-to-inverter compatibility, minimum and maximum string lengths, module electrical characteristics, and permitted DC-to-AC sizing before installation.
Specifications Explained
- Rated input power: The S440-1GM4MRMP variant supports PV modules up to 650W DC.
- Maximum input voltage: 60V DC, so the connected module’s electrical characteristics must remain within the optimizer’s permitted input limits.
- Maximum input current: 15A, supporting modern higher-current PV modules when correctly matched.
- MPPT: Module-level maximum power point tracking allows each connected module to be individually optimized rather than relying solely on string-level performance.
- Efficiency: Up to 99.5% maximum efficiency and 98.6% weighted efficiency.
- Rapid shutdown: Designed as part of the SolarEdge PV rapid-shutdown architecture and compliant with applicable NEC rapid-shutdown requirements when installed in a correctly designed compatible system.
- Connections: MC4 input and output connectors are provided for standard PV wiring integration.
- System design: The optimizer must be used with a compatible SolarEdge inverter and installed within SolarEdge’s specified string-length and connected-power limits.
