Solar battery charge is measured in terms of state-of-charge (SOC) – otherwise known as the voltage within the battery. If you want to know how to check what charge your solar battery has, just keep reading! What is the state-of-charge of a battery?

How do you charge a solar battery?

The first way to do this is the easiest: first, charge the deep cycle batteries within your solar battery bank fully. Next, check the voltage of each battery using a multimeter and make a note of each level, then let them sit without a connection to any solar panel for a few days.

Can You overcharge a battery using a solar panel?

Yes, you can overcharge a battery using a solar panel. Most photovoltaic panels that are 12v will produce around 16 to 20 volts, and most deep cycle batteries will only need about 14 to 15 volts to be fully charged. As we touched on above, a solar charge controller is used to ensure a battery does not get overcharged.

Are solar charge controllers causing battery drainage?

Many people think that solar charge controllers or inverters are responsible for battery drainage, especially at night. However, solar charge controllers actually prevent battery drainage. So, it is highly unlikely that your solar panel or other components are causing the battery to drain.
