How to connect solar panels and batteries?
When the solar cell and the battery are connected, it is best to use a photovoltaic charging controller, which can control the output voltage of the solar cell, protect the battery from being overcharged, and prevent the battery from flowing back when the solar cell does not generate electricity at night. .
The connection method is as follows:
Solar battery----Photovoltaic controller---Battery --- DC load.
While the solar energy is charging the battery, it is completely feasible to supply the battery to the outside. In this case, the power used by the load will preferentially use the power of the solar battery directly, and the remaining charge is charged into the battery; on the contrary, if the solar battery is insufficient Will take power from the battery at the same time.
