We are using two ET340 Meters, one for the incoming Grid and one for the PV.
The calculations of AC Loads and Critical Loads are very obviously wrong.
With no PV
With just L1 Enphase inverters on:
With all 3 phases on:
If we change the Meter programming to AC Input (intentionally wrong but just testing):
Incorrect load showing on critical (as expected because the PV is physically on the AC output.)
It seems that the loads are being calculated wrong. L2 and L3 are showing critical load when there is no MultiPlus on there phases and the total calculated plus the grid export is higher than the Production by nearly double.
Try turning “Inverter AC output in use” which removed the Critical load calculation and the AC Load calculation still reads wrong values.
Anything else we can try?
