hi all. I used the motorhome at the weekend. I checked the solar controller and all lights were full as if the batteries were fully charged but an hour or so later my inverter signalled low battery. does anyone think this could be the batteries or the controller? the batteries were new 3 years ago and they have always been fully charged whilst parked up using a battery charger plugged into it

You really need to disconnect the solar and charger if hooked up and wait an hour or so with everything turned off before checking the battery voltage at the batteries
Checking with the panel and hookup connected will show the charge voltage, not the true battery voltage
