Kehua SPI125K-B is a three-phase grid inverter designed for industrial use in all weather conditions. It has 9 independent MPPT inputs and H4 connectors. The inverter has SPD AC and DC overcurrent protectors. It has anti-island, reverse polarity, short circuit, and overheating and shock protectors. The inverter also has integrated DC switch which allows safe usage of the PV system, and remote monitoring which provides easy configuration, viewing the system’s operation and energy export. To increase efficiency, the inverter has PID protection and, for safety, a fault detection function for its own electrical systems.
