Hi folks, so I got a 840ah Trojan battery bank, about 2yrs old. I have a battery extra desulphating unit connected all the time. My Victron energy meter is set up correctly I believe. I have an auto start generator set to come on at 11.05volts. However, my %SOC usually states this is just 84% of my capacity. I know voltage is a tricky way to judge the discharge, as if I take a high draw,say 800w coffee machine, the capacity has to be over 95% for the voltage not to drop below 11v. We leave our inverter on 24/7 to run a germicidal lamp for our water system. So my question is: if I set the generator to come on at say 10.5v is that going to damage my batteries if it is still saying I’m above 50%capacity? Today the Generator came on at 84% or -156ah. I don’t seem to be making full use of the capacity of the batteries. I find looking after the batteries a minefield of difficult judgements!
Any help much appreciated!
