HK300E-PV Series Solar Pump Inverter

The Hznon HK300E-PV series is the high-power solar pump inverter of the range, combining MPPT (Maximum Power Point Tracking) with dedicated motor drive technology to maximise the power delivered by the solar array. It works with both AC and DC input and its AC output drives normal AC pumps, automatically switching to single-phase or three-phase AC input such as a generator or the grid when solar power is unavailable or the sunshine is too weak. The HK300E-PV series covers 1AC 220-240 V pumps from 0.4 to 5.5 kW, 3AC 220-240 V pumps from 0.4 to 11 kW and 3AC 380-460 V pumps from 0.75 to 1000 kW, making it suitable for large irrigation schemes, community water supply and desert control projects. MPPT efficiency reaches 99.9%, the output frequency range is 0-600 Hz, and the enclosure is IP20 as standard with IP54 optional. Built-in self-checking covers dry running, weak sunshine and full water level, with motor soft start and speed control, up to 30 general fault protections and detailed fault recording with automatic reset. Optional remote monitoring reports all operation data and fault information of the inverter.
