Hello, I have a 330w LG Solar panel connected to a Victron 100/30 controller which in turn is connected to 2 110ah Banner batteries. The controller app has been, for 4 weeks now, showing the state to be off. I have discovered my leisure batteries are on their last legs. Could this be why? If not any ideas why it is not turning on? I am not techie in any way so simple terms would really be appreciated. Many Thanks
