The series of centralized inverter (without transformer), installed along with DC power distribution cabinet, AC high-voltage power switchgear, medium voltage step-up transformer, communication tool box and other ancillary equipments within one single tailor-made room, can help reduce the internal installation and wiring procedure. The inverter, with its lower cost, easier installation and commissioning, especially fitting for dusty, Gobi, high-altitude and extreme cold environment solar PV plants.
