@Teeniiola@WoliagbaI Also depends on the years you’ve been using your batteries, they might not be effective as they’re when you first install them.
You can seek out an installer advice on what really is going on
@Teeniiola@WoliagbaI firstly we are experiencing low sunshine at this season which could reduce the rate at which the batteries are charging. The solar panels surface might be dirty also which could also reduce its efficiency. And depends on the types of solar panels you’re using as well..
