Hi Guys,
I'm having a really rough time. We were camping some weeks ago and came home to no power. In the morning when the sun came up it charged for about an hour. The sun stayed out but the charge controller suddenly reported that the solar was pulling zero watts. The battery voltage was around 11.3 so should still be charging.
It's a fairly new setup other then the leisure battery. We have an expensive 180w back reinforced solar panel going into a smartsolar mppt 75/15.
I've just replaced the battery with a 100Ah lithium LiFePO4.
To my despair it still behaving the same way. The brand new battery is at 13.17 volts but the state still says off. It's a nice sunny day and the solar panel says 0W.
Any pointers? I'll be hugely grateful.
