Regardless in the following article, we will discuss how to check if your battery is getting charged, why is your panel not charging your battery, more about system wiring fault, faulty battery and charge controller settings, and how to fix each of them in detail. . Today I noticed the MPPT was not sending any more electricity to the batteries. It seemed to be treating 88% charged as if it were 100%. When the pump was on, I could read the (-) amp draw from the battery bank, and when. . Got the victron display to read 83% though, which is an improvement from the 82% it was stuck on. even if I get to above 75% and then after that have 5kWH of unused energy in the day. . So by year 10, you only got 63% of rated capacity, ie 6. 3kWh and the actual available power is closer to 5. 5kWh due to BMS self consumption.

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?
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.
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.
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.
