Solar inverters are becoming more and more popular now. Now that oil and electricity prices are rising, free, environmentally friendly and recyclable solar energy has become the best choice. For agriculture, irrigation used to be mainly carried out by manpower, which was inefficient and had low yields. With the popularization of modern agricultural machinery, water pumps are widely used to irrigate crops, which are highly efficient and can release human resources. However, water pumps require electricity to power them. In Southeast Asia and Africa, the main cultivated land is often in remote areas, and the national power grid cannot be extended to the cultivated land. So the solar water pump inverter was born. Solar energy can be directly used to power the water pump, solving the power supply problem of the water pump.
