F34 - AC_Overload_Fault

Why am I getting F34 - AC_Overload_Fault?

When inverter is off and not supplying any AC current.

I have two 8kw units which will be run in parrallel when I have the Batteries which are on order, delivery mid October. I have one connected to supply from half of the panels solar energy to our load set as standard inverter via Grid in/out, Load ouput isolated. (grid, through CT, Load, then to inverter) When solar enargy stops at about 18.46 the inverter switches to off, I assume this is correct then just after about 5 minutes I get a notification F34 - AC_Overload_Fault and again at 22.17 another notification F34 - AC_Overload_Fault, this has occured on the two days it has now been running.

How do I solve this?

I had the same error. Once the battery was connected it hasn’t appeared since
