Commercial String Inverters

36kW, 1000Vdc String Inverters for North America

CPS is excited to add the new 36kW three phase string inverter to its product portfolio for North America.  The medium power series of grid-tied, transformer-less  inverters are cost effective, efficient and flexible modular inverter building blocks for rooftop and large ground-mount solutions.   The 36kW is an extension of the existing 23kW and 28kW inverter line and features a dual MPPT design with up to 98.6% conversion efficiency and wide operating window of 240-950Vdc.   An installer friendly and integrated wire box simplifies installation and reduces BoS costs.
