The Kehua SPI60K-B is a three-phase grid-tied inverter designed for all-weather industrial operation. It has 4 independent MPPT inputs with the ability to connect 3 strings per input. MC4 input connectors. The inverter has built-in class II AC and DC surge protection devices (SPD). It is equipped with island operation protection, reverse polarity protection and overheating protection. The integrated DC circuit breaker guarantees safe operation of the PV system while remote monitoring provides convenient configuration and supervision over system operation and energy export.

The inverter features an intelligent, automatic software update function. It is easy to upgrade and maintain. Another important advantage is its low harmonic distortion with THDI of less than 3%. For safe and efficient operation, the inverter automatically recognizes faults and analyses its own and the system’s failures. It intelligently identifies and positions malfunctioning PV modules.
