Commercial String Inverters

14/20kW Grid-tied PV Inverter for North America

The CPS SC14/20KTL-DO grid-tied  transformer-less PV  inverter is an  ideal building block for 600VDC commercial  three phase applications. The integrated and flexible wiring box eliminates the need for DC combiner boxes in the field. Dual, and independent, MPPT’s enable granular power conversion and design  flexibility. The unit  is easily serviceable with a  replacement unit  in  the  field, signifcantly improving uptime over the life of the system.
