EM24 or ET340 -> ESS on 3phase grid, 1x Multiplus 2, Belgium (slimme meter)

Which is the best meter for the Belgian market in Flanders?

- 3 phase grid
- 1x Multiplus 2 5000W
- 1x Cerbo GX
- 1x Cerbo touch 50 (because it can)
- 1x ET112 (for monitoring solar panels, mono phase inverter)
- EM24 or ET340 ? (net monitoring)


I am talking about the 3 phase "smart meters".
I definitely want to use phase compensation!
So the sum of the consumers of the 3 phases must be fed back over 1 phase to the grid.
(which the Multiplus 2 is connected to)

Which meter is the most suitable? (EM24 or ET340)

In a system with 3-phase grid and only 1-phase ESS you should use an EM24.
With the ET340 you would get visualization errors (but the system would work as good as with the EM24).

I have the same setup in Belgium. but have used an et340 as grid and an et112 for the pv. the data on vrm are not correct in any way. would this be solved with an em24?
