SolarEdge S1000 / S1200 Power Optimizer – 25-Year Warranty, 99.5% Efficiency, Module-Level MPPT

The SolarEdge S1000 / S1200 Power Optimizers are engineered for maximum ROI in commercial and utility-scale solar projects. With 99.5% peak efficiency and module-level MPPT, they maximize energy harvest from every panel — even under shading, mismatch, or complex roof layouts. Designed to support high-power and bifacial PV modules, they enable higher string currents for greater system output per string. Built-in SafeDC™ automatically reduces DC voltage to touch-safe levels during grid/inverter shutdown — ensuring installer and firefighter safety. The integrated SolarEdge Sense Connect enables continuous connector-level monitoring to detect overheating from installation issues or wear. Flexible design allows up to 2x longer strings and 50% fewer cables, fuses, and combiner boxes — slashing BoS costs. Supports connection of two modules in series with easy cable management. Remote, module-level monitoring enables pinpoint fault detection and time-saving troubleshooting. Backed by a 25-year warranty — the smart choice for scalable, safe, and cost-effective solar systems worldwide.
