My solar panel has died I think. (It’s only 5 years old) Before August the control panel shoed green light indicating it was supplying electricity to the battery.
August holiday control panel showing red lights for leisure battery circuit (and on main battery circuit which isn’t even connected e up!) I know Leisure battery is on its last legs as it doesn’t hold charge for very long. (Leisure Battery also charges from split charger when on the move). Red lights eventually went out and I ran a meter over the connections and nothing coming out of controller to battery. Nothing coming in from solar panel.
Any thoughts before I tear the whole lot of and start again?
Have you tried an alternative panel? I have a couple of spares you could borrow, not very big but enough to prove if the panel is at fault else it is the controller.
Did you test at controller end or panel connection end? Could it just be a cables been nicked on the way out from the panel to the controller rather than the full panel failing altogether?
