SolarEdge S500B S-Series Power Optimizer (125V / 15A) The SolarEdge S500B Power Optimizer is a module-level power electronic (MLPE) designed for high-power and high-voltage PV modules. IMPORTANT: This optimizer is designed to work exclusively with SolarEdge inverters. As a cornerstone of the advanced S-Series, the S500B mitigates module mismatch—from shading to manufacturing tolerances—ensuring each panel operates at its Maximum Power Point (MPPT). With a 125V maximum input voltage, the S500B is the ideal solution for high-efficiency modules, providing industry-leading safety with Sense Connect technology. Verified SolarEdge S-Series Documentation Download SolarEdge S500B Datasheet (PDF) Key Benefits & Compatibility Exclusive Ecosystem: Engineered specifically for use with SolarEdge Inverters only to utilize fixed-string voltage technology. SolarEdge Sense Connect: Advanced safety that monitors PV connectors for overheating, preventing potential electric arcs. High Voltage Support: Compatible with high-power modules featuring an Absolute Maximum Input Voltage (Voc) of up to 125V. Maximum Energy Harvest: 99.5% peak efficiency ensures minimal energy loss across the string. SafeDC™ & Rapid Shutdown: Automatically reduces DC voltage to 1V per module during inverter shutdown for NEC PVRSS compliance. Module-Level Monitoring: Real-time performance data is transmitted via the SolarEdge inverter to the Monitoring Portal.
