SolarEdge Power Optimizer S440

SolarEdge Power Optimizers enable the maximization of the amount of energy each solar module produces and mitigate diverse types of module mismatch loss, from manufacturing tolerance to partial shading and aging.

The S-Series Power Optimizers provide advanced safety features, simplified wiring for faster installs, and smart remote monitoring. They also continue to boost module-level power generation with DC optimization and allow users to experience 100% system visibility with module-level monitoring.

The specific Power Optimizer analyzed in this EPD is our S-Series S440 Power Optimizer. It supports PV panels up to 440Wp, has a maximum input voltage (Voc) of 60V, and has a weighted efficiency of 98.6%.

SolarEdge’s smart energy solutions offer both design flexibility and performance reliability at the level of individual solar panels, ensuring operation at the highest efficiency at all times, independent of string length and temperature. SolarEdge module-level power electronics (MLPE) technology is designed to generate energy more efficiently over the system’s lifetime than traditional string technology. This allows higher energy yields by overcoming module mismatch and shading losses.
