Hey Everyone!
My Growatt is displaying fault 08: high bus voltage anytime the panels (3 x 440W bifacial in series) are in direct sun during peak hours. I don't know anything about anything but it seems like my panels are overwhelming the Growatt.
My battery is custom built LiFePo4 with no BMS (photo attached).
Is there a setting I'm missing that would prevent this fault from happening? Thanks!
Settings:
01: SBU
02: 60A
03:APL
04: Sds
05: US2
06: auto restart enable
07: enabled
10: Number of series batteries: 2 (very uncertain about whether this one is right!)
11: 30A
12: 24.5V
13: 27V
14: CUt
18: bYD ( overload bypass disabled... Maybe this has something to do with it? I don't know what "line mode" means in the instructions)
19: 29.2V
20: 29.2V
21: 24V
22: SbE
Everything else default settings. Thanks again!
