Guy Stewart mentions in this webinar https://youtu.be/Fm6FdpClLBo?t=3541 that you should not use Fronius Smartmeter in a ESS system but then in the diagram right after it's shown, is that a mistake ?
My house is running 3 phase system and consumption is across those 3 phases which is normal here Denmark. I was planning getting a one phases Fronius Primo 3kw and a Multiplus II 3000VA. Install the Fronius on AC IN meaning on the grid directly (not on the AC OUT) and of course a grid meter EM24 Ethernet that is recommended so both Fronius and Multi are one phase. The ESS documentation states to place the Multi on L1 but the fronius should be on what phase ? Doesn't matter ? Is there a required of a second energy meter in this setup ? In denmark most of us have new grid meters from the energy company which summs up on all phases so consuming on one phase 1kw and producing on another phase 1kw yields 0w usage e.g no penalty or cost therefore no need for 3phase inverter.
