Growatt still giving "03" error (battery overcharged)

Thanks, I will try USE and see if there is any difference. I think I have gotten rid of my fault codes and error since I adjusted the voltages.

My last remaining problem which might be a little more difficult to get rid of, is that when I have my inverter on SBU, after the sun goes down and it goes to battery only, my lights start to flicker after an hour or two. I usually switch the inverter to UEI(utility) and that solves the problem. It happened tonight and the battery SOC was 82%. I am not getting to use my battery and maximize the savings on my electricity bill.
