1500V 1.25MW Grid-Connected PV Inverter EA1250KHV


Compared with traditional centralized 1000V inverter, EA1250KHV is featured with high DC side voltage (Max. 1500V), it reduces DC side current, cutting down the investment cost of DC cables and DC combiner box, and increases the output voltage of AC side, reducing current and power loss, that increases efficiency of the system solutions and decreases costs of total solutions.
