Hi
have installed Quattro 8kva with 8kW Fronius AC coupled with a CCGX 800Ah of batteries. It is an off grid installation with PV inverter assistant on.
The problem is my battery is completely discharged, but the SOC still reads 82%. My SOC when bulk charge is complete is 85%. I also noticed that when charging, once the SOC rises to 85% the quattro light switches to Absorption. it takes less than an hour for it to reach 85%.
It wasnt like this originally, the SOC used to go as low as 60% but never below, this started after i added more panels to my setup. i have tried all the charger settings and nothing changes. Also i feel because of this, my battery bank is never fully charged. After spending 30mins in the bulk stage, it stays in the absorption stage for more than 8 hours , and after this the SOC is still just 90%.
I have no other battery monitor connected and no other load is connected to the batteries aside th Quattro.
