Problems solved by technology
[0002] Photovoltaic water pump system is a system that directly uses the photovoltaic effect of solar cells to generate electricity, and then through a series of control and execution links such as power electronics, motors, and water machines to achieve water pumping in rivers, lakes or deep wells. It does not need to lay power grids, construction planning Simple and other characteristics, the photovoltaic power generation threshold corresponding to the start-up threshold of the pump head in the existing photovoltaic water pump system is relatively high, so that the photovoltaic water pump system needs strong sunlight to operate normally. In order to solve this problem, the conventional solution is to increase the amount of photovoltaic modules , however, the input cost will also increase accordingly, and the excess power cannot be fully utilized in an environment with high light intensity. Therefore, it is necessary to propose a photovoltaic water pump control method
