Sunsynk Hybrid Bi-Directional Inverter Fault Code
Two weeks ago I had a solarPV system fitted which included the relatively new Bi-Directional inverter. I have 4.56kWp of Q-Cells fitted pointing East and South and connected via a Fireman's Switch. No battery (yet).
For several days all went okay, but the last 5 days I've been getting the error code F15 SW_AC_OverCurr_Fault.
The manual does not mention this code. Can anyone enlighten me please?

I did precisely that several days ago. I got an email requesting the Serial Number but nothing since. Oddly, the day after they requested the Serial Number, it hasn't faulted once. Is it possible for Sunsynk to log on to my inverter just with a Serial Number and make adjustments without me knowing? They haven't contacted me since but it seems odd it's not faulted since either.
