5KW Inverter F39 Fault Code
Hi all.
I have a Sunsynk 5KW inverter with Sunsynk 5.32kw Lithium battery installed and started receiving F39 DCLLC Overcurrent fault when battery is fully charged by solar.
What is the root cause and how should it be solved?

Hi there
Just came here looking for advice on this same fault code F39 - DCLLC_Over_Current So far has only happened once at 14:03 today with my SunSynk 3.6kW inverter plus 2x SunSynk 5.12kW batteries. Batteries are at 100% charge but have been like that throughout the day.
Otherwise the installation appears to be working well, still generating PV, serving the load in the house, and exporting a small surplus. Any ideas anyone?
