SolarEdge Power Optimizer S440 Product Description The SolarEdge Power Optimizer S440 brings module-level power optimization to your solar PV array, ensuring maximum energy harvest and advanced safety. Designed specifically for use with SolarEdge inverters, the S440 tracks the maximum power point (MPPT) of each panel individually, overcoming losses from shading, mismatch, or differing roof orientations. Intelligent monitoring and SafeDC™ technology ensure both performance and peace of mind, making it ideal for demanding residential solar systems. Module-Level MPPT: Extracts the maximum power from each panel to maximize overall system output. Superior Efficiency: 99.5% peak efficiency, 98.6% weighted efficiency. Advanced Safety: SafeDC™ automatically reduces voltage to safe levels when the inverter or grid is switched off. Flexible Design: Allows for longer and uneven strings, supporting multiple orientations and panel types. Compatible with High-Power and Bifacial Modules: Supports up to 440W modules and advanced panel technologies. Rugged Reliability: Designed for use in extreme environmental conditions. 25-year warranty. Quick Installation: Toolless rail or single-screw mounting and simplified cable management.
