Chint Power Systems > 50,000 Watt 480 VAC 3-Phase Grid-Tie Inverter for Commercial Applications with Standard Wire-box
50kW-480V, 1000Vdc String Inverter with Standard Wire-box for North America, Commercial String Inverter
Note: Inverter and wire-box often ships separate. Ships via freight direct from manufacturer.
The 50kW (55kVA) medium power CPS three phase string inverters are designed for ground mount, rooftop and carport applications. The units are high performance, advanced and reliable inverters designed specifically for the North American environment and grid. High efficiency at 98.8% 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.
This CPS 50kW inverter ships with the Standard wire-box. Tigo or APsmart Rapid Shutdown wire-box versions also available. CPS SCA50KTL-DO/US-480 inverter is fully integrated and separable with touch safe fusing, monitoring, and AC and DC disconnect switches. The integrated PLC transmitter in the Rapid Shutdown wire-box enables PVRSS certified module-level rapid shutdown when used with the Tigo TS4-F/TS4-A-F/TS4-A-2F products, APS RSD-S-PLC/RSD-D products. The CPS FlexOM Gateway enables monitoring, controls and remote product upgrades.
