Dc Inverter Heat Pump

  The water pump inverter is usually composed of a rectifier unit that converts alternating current into direct current and energizes a direct current intermediate circuit or a direct voltage intermediate circuit, and an inverter that is fed by the intermediate circuit. The inverter eye can output the chord-stop voltage with the desired frequency and interval. When driving the three-phase AC motor of the inverter, it can provide the motor with stepless acceleration from zero to rated speed without reducing the torque.

   Because the water pump frequency converter will generate strong electrical interference signals on the motor power line, it is usually necessary to shield the water pump frequency converter. In addition, a sine wave filter can be installed between the water pump inverter and the pipeline booster pump motor to convert the PEM wave output by the frequency conversion into a sine wave.

The solar pumping inverter obtains DC power directly from the solar panel and converts it into AC power to supply the water pump to pump water. According to the intensity of sunlight, adjust the real-time output frequency to obtain the maximum power point tracking (MPPT) and maximize the use of solar energy.

Based on the design concept of developing environmental protection and economic photovoltaic products, water storage is used instead of electricity storage. Without battery device, water pump is directly driven to lift water. The reliability of the device is high, and the cost of construction and maintenance is greatly reduced.
