We bought a used T@b400 with a victron 712 already installed. It does not seem that the state of charge is reading correctly. I shut off the battery and let it sit a few hours - the hand volt meter we are using says 14 volts which is similar to what the victron says for volts but the SOC is saying 27%.
The battery is a C235 so we did set the battery capacity at 235 instead of the default of 200 and we set the full charge V at 13.7
We are not able to see that any power is coming in to the batter either even on a sunny day- it does have the factory solar
We are a little lost with all the technical info on all this but it does not seem that the SOC Is correct or are we not testing that correctly? My husband is putting the volt meter on the leads going from the battery to the converter not directly on the battery - is that ok or should it be right on the battery like you read your car batter?
