Solar cells use the photovoltaic effect to convert solar energy into electricity. The water pump designed to adapt to the output characteristics of solar cells is called photovoltaic water pump. It is different from the conventional submersible pump. In order to optimize the best match between the motor water pump and the solar cell, and to ensure the long-term unattended high reliability performance of the photovoltaic water pump, the electromagnetic parameters of the motor and the overall structure are different from the conventional submersible pump.
Conventional submersible pumps driven by three-phase AC asynchronous motors can be controlled by frequency conversion and speed regulation by general frequency conversion inverters, so as to achieve the purpose of energy saving and protection of motor water pumps. It converts the commercial power with fixed voltage and frequency into AC power whose voltage and frequency vary with the load in the form of AC-DC-AC or AC-AC, while the photovoltaic water pump driven by three-phase AC asynchronous motor uses solar cells For power supply, since the output of solar cells is direct current that changes with the intensity of sunlight, it is not enough to control this photovoltaic water pump only by frequency conversion and inverter technology, and the output characteristics of solar cells must be considered.
