When connecting solar panel and batteries, it is best to use a solar charge controller, which can control the output voltage of the solar cell, protect the battery from being overcharged, and at the same time, also at night when the solar cell is not generating electricity, to prevent the battery's electricity backflow.
Connections are as follows:
Solar Battery ---- Solar Charge Controller --- Battery --- DC Load.
Solar panel and battery connection method
First of all, prepare materials: a solar panel, a solar power controller, a battery, a number of connecting wires.
Solar panel wiring method:
1, first of all, use the connecting wire to connect the solar power controller and the battery, the positive pole of the solar power controller connects to the positive pole of the battery, the negative pole of the solar power controller connects to the negative pole of the battery.
2, and then use the connecting wire to connect the solar power controller and the solar panel, the positive pole of the solar power controller connects to the positive pole of the solar panel, the negative pole of the solar power controller connects to the negative pole of the solar panel.
3, so that the solar panel wiring is connected successfully, the need for external loads can be connected directly to the solar power controller output can be.
