Sunsynk inverter with AGM lead acid batteries.

[spence65]

How are Sunsynk's SOC figures calculated for AGM batteries? I have 24 of 2v batteries in my system. 50v would be appox 50% soc. But the figures are nowhere near this and it is always different, because of this I've had to set the batteries to control on volts which isn't a problem. It bothers me why the SOC % Is so far out.

Also when charging the voltage never drops off from absorption. With the batteries claiming SOC 100% or >55v the charge is still>57.5v. Float is set at 55v. Which would suggest the batteries are always being over charged. All settings are correct for battery type.

Any help appreciated

Also this is is a typical day of charging. Surely double the charging to discharging doesn't make sense?

It might be the setting problem
If the manuel shows how to correctly set the inverter to the Lead battery ?
