250/275kW V2, 1500Vdc String Inverters for North America

The 250/275kW V2 high power CPS three phase string inverters are designed for ground mount applications and include integrated PID mitigation to help reduce or eliminate Potential Induced Degradation. The units are high performance, advanced and reliable inverters designed specifically for the North American environment and grid. High efficiencies, wide operating voltages, broad temperature ranges and NEMA Type 4X enclosure enable this inverter platform to operate at high performance across many applications. The SCH275KTL inverters include a selectable Active Power of either 250kW or 275kW (factory default) with 12 MPPTs and are available with either 36 fused PV string inputs or 24 unfused PV string inputs. The CPS FlexOM solution enables communication, controls and remote product upgrades.
