SolarEdge S440: Reliable Optimisation for Residential and Commercial PV

The SolarEdge S440 Power Optimizer enables enhanced panel output by providing module-level MPPT and performance tracking. It ensures each panel operates at its maximum capacity regardless of shading or mismatch—delivering a smarter, safer solar system.

Maximise Output Across Every Panel

The S440 allows solar arrays to perform better in partial shading or challenging layouts. Each unit connects directly to a single panel, ensuring maximum power harvesting at the module level. It's especially useful for rooftops with different orientations or when using high-output PV modules.

• Rated for up to 440W STC PV modules
• Module-level MPPT for optimal yield
• Reduces impact of panel mismatch or shading

Improved Monitoring and Safety

By connecting the S440 with a SolarEdge energy meter, installers and users gain precise, real-time insight into system performance. In addition, automatic panel shutdown features increase onsite safety.
