- 2 paralleled MP II 48/5000s
- Single phase
- ET112 energy meter
- All loads on ACout1
The current reading of the ET112 is quite different to that of the MP II current sensor. The differences point to possibly a calibration and a scaling issue. It appears that ET112 is correct when compared to a clamp meter, which means that the MP II is most likely incorrect.
- Blue circles are when the grid fails, and both read Zero
- Magenta circles highlight examples of variances
The same phenomena are being seen on other systems as well, with various versions of inverter firmware. Single and 3 Phase systems, all with the MP II 48/5000
How can this be fixed?
