Commercial String Inverters

100 & 125kW, 1500Vdc String Inverters for North America

The 100 & 125kW (111 & 132kVA) medium power CPS three phase string inverters are designed for ground mount and carport applications at 1500Vdc. The units are high performance, advanced and reliable inverters designed specifically for the North American environment and grid. High efficiency at 99.1% peak and 98.5% CEC, wide operating voltages, broad temperature ranges and a NEMA Type 4X enclosure enable this inverter platform to operate at high performance across many applications. The CPS 100/125kW inverters ship with either the standard or “centralized” wire-box. The standard wire-box includes touch safe fusing, surge protection, AC and DC disconnect switches. The new “centralized” wire-box is designed for sites benefitting from DC combining near the array and locating the inverters closer to the point of interconnection. Both wire-box versions employ the CPS separable, “quick connect” wire-box design saving time installing and servicing the product. Inserting the CPS FlexOM Gateway in either version wire-box enables communication, controls and remote product upgrades required in today’s PV plants.
