Xantrex Truecharge2 Reliability?
Hello all, New member here with a 2015 Rockwood 2306 that we picked up June of 2018. We're upgrading from the terrible group 24 battery to a set of two Trojan T-105 batteries. I'm looking for a sui...

Yes, but when recharging the voltage has nothing to do with SOC, so that leaves SG.
With AGMs you don't have SG, but now you do have an ammeter (Trimetric say) to tell when they accept 0.5a/100AH at 14.4 as your marker for full. Not voltage.
But other times you can just use voltage for a general idea of SOC when loads are mostly not running. EG, off-grid your "morning voltage" with the furnace off at the moment, and no lights on, and before solar comes on to jack up the voltage, you can see it is say 12.1 and that means you are at about 50% (Trojans--some others 12.2) so you need a recharge. You don't need an SG reading for that.
Compare your voltage with the AH counter to see if they "match" for approx. SOC. If they don't match, you have a clue to look for why. Such as you left the converter on when on inverter. :(
Don't believe your battery monitor Percent SOC. Believe the SG. (At home--you don't need to take an hydrometer camping--you never get to true full while camping off-grid so who cares if you stop the gen at 89 or 91 SOC?
