So i have a recently installed diy off grid 24V solar system comprised of 4 230W panels, a 60amp charge controller, a 3000W inverter/charger and 8 6V batteries wired in series/parallel. One set of batteries is new and the other set was 90%. I am having a hard time understanding why my voltage readings from charge controller, inverter and meter are all over the place. An example...this morning under load the CC reads 60% (24.6V),the inverter says 83% (25V) and my voltmeter reads 24.8V which is mid-way between the two. Which one should i trust for an accurate reading of SOC? The voltmeter?
Anyone experience this?
thanks
