Shenzhen Hznon Solar Technology Co., Ltd.

Shenzhen Hznon Solar Technology Co., Ltd. (Hznon) develops and supplies solar pump solutions built around its own solar pump inverters. A complete Hznon solar pump system consists of a solar array, a solar pump inverter, an AC water pump, a solar DC combiner box and a water tank, using the solar cell as the power supply to lift water from deep wells, rivers, lakes and other water sources. It targets areas that lack water or have no reliable power supply. The inverters adopt MPPT (Maximum Power Point Tracking) and dedicated motor drive technology to maximise the power harvested from the solar panels. They accept both AC and DC input, and the AC output drives a wide range of normal AC pumps from 0.4 kW up to 1000 kW. When solar power is unavailable or the sunshine is too weak, the inverter switches automatically to single-phase or three-phase AC input from a generator or the grid, so the water supply keeps running. The platform offers 99.9% MPPT efficiency, an input DC range of 150-450 V on 220-240 V models and 250-900 V on 380-460 V models, a recommended MPPT voltage of 320 V or 550 V, 0-600 Hz output and an IP20 enclosure with IP54 as an option. Protection covers up to 30 general faults plus solar pump specific functions for dry running, weak sunshine, full water level and water level sensor failure, with motor soft start, speed control and automatic fault reset. Optional remote monitoring reports all operation data. Applications range from daily water supply and irrigation to desert control, livestock drinking water, sewage treatment, fountains and swimming pools.
