Hi all,
I am testing a setup with a LifePO4 battery, Multiplus II 48/5000 and Cerbo GX Mk2 (as well as RPI 3 with Venus for testing software). I still have to decide to go for the 1 phase or 3 phase MP setup.
I have a 3 phase grid with AC-in coupled PV on 2 phases. I also have some SDM630 energy meters (installed 2 years ago) and an ET340 which is not yet installed. I have configured a 0 grid consumption on the ESS which seems to function fine, however I have a problem with the grid consumption counters that I am only experiencing with the Victron interter. When I am feeding 1kW in the grid for 1 hour to compensate 1 kW consumption, the SDM630 is counting 1 kW import and 1 kW export. I already switch phases to have the Victron on the phase with most consumption but the behavior is exactly the same. If I just count (estimate) the consumption base don the reported power of each phase, the import consumption is approx. 0. I am not experiencing the same behavior with the Solar Inverters (old SMA HF), the meter is reporting the excess solar production as export and the net consumption as import correctly. Has anyone any idea what could cause this?
