We are fitting a large commercial install at present and reasons beyond our control means we cannot fit an Energy meter to the incoming supply
This is a 3 phase install
We are wondering, is there a way we can buy 3 x 100A CT clamps and install one on each Multiplus and route these to the incoming supply (one each on L1 L2 and L3)?
I don’t know the answer to your questions about ct but:
why not use the internal measurement of the inverters ? I you route your energy through the mp2 you can use their internal current sensors. Energy meters (and maybe CTs ?!?!) are only needed in case of using energy between grid and mp2.
I guess that you can’t, for some unknown reason, use a 1-fase MID certified kWh meter on each MultiPlus or a 3-fase kWh meter on the supply line to the MultiPlusses?
