The Setup:
Multiplus II 10KVA, Loads and AC coupled PV on AC IN 1 and I have the optional CT for MP II on the Grid perimeter
Initially the dashboard was slightly wrong and the PV production was cancelled out by the AC Load, I understand the MP II has no way to show this so the Dashboard was correct based on what the MP II could see. I decided to add a Meter to the PV to be able to see the PV Production.
I added a EM24 (ethernet) on the PV Inverter up in the loft. Since installing I am now experiencing
As quoted in 1.2 of ESS Guide
"In particular, without a grid meter:
- When renewable energy is being provided on the input side, the grid value will be wrong (too low/negative); and
- The AC Load value shown will be too low (and will show zero where there is a surplus of renewable energy)."
I thought the built in MP II CT (option) and Energy Meter where equivalent however I’m now thinking this is not the case. Can someone confirm this or have I missed a setting somewhere?
