We have an installation where a MultiGrid measures/calculates bogus power values.
The powers to the left (grid, pv and battery) are all correct.
However the AC loads value is way off.
Strangely, the inverter measures negative power values on both ACin and ACout.
However, nothing is connected to ACout at all!
We have tried to "redetect system" as described in the FAQ, but that didn't help.
What could be the problem here?
Thank you
Ivo
