How do I make sure my solar panel is charging the battery correctly?

To test that the solar power supply system has been installed and performs properly you need a multimeter set to “Read Current” mode.

Step 1

To begin with you should check if the output from the solar panel is correct. You should do this on a sunny day (Please connect the multimeter as shown in the drawing below).

Step 2

Now check that the regulator is charging the battery. There are lEDs on the solar regulator helping you to indicate if the regulator is charging the battery. But to be sure you should check with the multimeter (see drawing below)

In addition to dimensioning the solar power supply system correctly, it is important to position the solar panels appropriately for maximum electricity production.
