HV330 Inverter for PV Pump In some areas, people still use inefficient, energy waist to obtain water for domestic and irrigation, such as waterwheel, diesel pumps, manpower pumping, or manpower carry. Along with the technology improved and the environment protection demand, the PV water pumping system is perfectly meet the requirement of people’s demand of water. And solar is renewable energy, green and clear with no pollution, is meet the demand of environment protection as well. PV water pumping system is that, make the solar energy convert to electric energy (DC) through photovoltaic panels, then access the direct current to the inverter, and drive the pump, make the water from lower place to higher place to stored for use of life, agriculture and industry. And the inverter could adjust the drive frequency according to the intensity of the sunlight, and automatically star and stop according to the water level of the wells and the water tank, totally smart control. Features: 1. Max Power Point Trace (MPPT) Technology, which maximize the PV power generation efficiency. 2. Adjusting the pumping speed according to the sunlight intensity. 3. Automatically detecting the water level of the well, and stop running when it is at the low water level, which prevent the pump idling. 4. Automatically detecting the water level of the reservoir, that star running when water level is at the low point, and stop running when water level is at the high point, which prevent the water overflow in the reservoir. 5. It could access to external power – such as electric power or diesel engine – as the backup power source, when it is in the rainy days or the sunlight is weak, the inverter could switch to the backup source immediately. 6. Intelligent thermal protection design for IGBT module, which ensure the reliability of the product. 7. Complete protection system - over/under-voltage, over-current, short-circuit, phase-loss, over-heat, low water level auto-stop, etc. 8. Powerful inverter management software – HVManager, which could be realized the function of programming, debugging, setting parameters, monitoring, etc. If you want to know some information about our company,pls check our website: www.hopewindelectric.com
