i recently installed a solar system. i have a 8kw growatt inverter (model SPF 8KT HVM) and 4 lithium batteries (48v 100ah).
the system would charge the batteries until full (batteries show full lights) but the inverter shows 66% full and stops charging the batteries at that point. (it shows 66% both on app and inverter screen). when discharging, it discharges from the 66% point and switches off at 20% battery capacity according to the inverter, which is in reality 54% battery capacity. so basically there is 34% of the battery charge that i cannot access. as you can see in the attached pictures, when it hits 66%, only 74w go to the battery and the pv panels only generate enough power to cover the consumption.
i contacted growatt and they were not helpful. i hope someone here would help.
