Description

technical field [0001] The invention relates to a protection circuit for a solar controller, in particular to a circuit for preventing reverse connection and reverse charging of a solar controller, and belongs to the technical field of solar controllers. Background technique [0002] At present, solar energy is the first choice for green, environmental protection and sustainable development in new energy sources. Photovoltaic power generation technology has attracted more and more attention from all countries in the world and has developed rapidly. The solar controller converts the electric energy converted by the solar cell into the optimal charging mode to realize the charging and discharging management of the storage battery. However, in the actual use process, often due to improper use by the operator, it is easy to have the reverse connection of the positive and negative poles of the solar battery at the input end. In this way, during the charging process, the solar bat...
