December 15, 20223 yr Hi guys, I have a Deye 12KW 3 Phase inverter with 2 x 5.1kw batteries. The system runs with PV panels in support. I have been receiving the following error on the system - F33 AC_OverCurr_Fault This seems to kick the power out for a while and then the power comes back on as normal. This happens on and off during the day. Any ideas?
December 15, 20223 yr Looking at the support group, there seems to be plenty of 12K 3phase inverters throwing that error. Firstly, check to see that you have the latest firmware. Secondly, try to adjust grid parameters to have more latitude. If all of this fails , log a call with Sunsynk in the UK.

Restarted and all good again Thanks Edited April 14, 20233 yr by ZaydS

Proper distribution of load can help.
