About This Product
The SolarEdge S500B 500W/125V Power Optimizer is a module-level DC power optimizer designed for use with compatible SolarEdge inverter systems. It provides individual solar panel maximum power point tracking (MPPT), helping each connected module operate independently of the performance of other modules in the string.
The S500B-1GM4MBM supports solar modules rated up to 500W and features a 125V maximum output voltage rating. It is supplied with MC4 connectors for integration into compatible PV installations. This optimizer must be installed with qualifying SolarEdge inverters, with system sizing and optimizer quantities determined by the PV array configuration and inverter specifications.
