SolarEdge S1200 Commercial Optimiser - Extended

The SolarEdge S1200 Commercial Power Optimizer is a premium DC‑DC converter tailored for large-scale PV installations, handling two high-capacity or bifacial panels in series. Featuring module-level Maximum Power Point Tracking (MPPT), it maximizes system energy yield and eliminates losses from shading, soiling, mismatch, or aging—critical in rooftop, carport, and ground-mount arrays.

Built for safety and durability, the S1200 includes SafeDC™ shutdown to reduce DC voltage to <1 V during grid or inverter faults and Sense Connect™, continuously monitoring connectors to detect overheating or arcing before issues arise.

Its robust IP68/NEMA 6P enclosure and compatibility with harsh environments make it ideal for commercial use.
