EM330 - EM340 in 3x230VAC grid wrong readout

We installed an energy meter EM340 (in-line) grid meter and in another application an EM330 with current clamps. We see that if we program the meter to a 3P grid (3x 230VAC and no N), which still exists a lot in Belgium, that the Cerbo Measures 0VAC as line voltage. Therfore the internal calculation of power and consumption is not correct. Could this be a software issue from the Victron side? Because in the meter itself all values are correctly displayed.

Kind regards and thanks for the help.

Victron does not connect to delta connections.

They needs a neutral connection to work, so not likely able to reference without it.

Dear Alexandra

Thanks for your answer. We don't put the inverter in 3-phase config, we only use a single phase inverter in this case. The L of the inverter is connected to L1 and the N to L2 or L3.

What we would like to obtain is the phase-compensation regulation of Victron in this configuration, because this could help us store the PV-inverter energy which is somtimes connected to a different phase or phases.

So we would like to know if there is anything to be done about the wrong read-out of the values from the Energy meter itself.

Thanks and kind regards

Going to follow this as I'm design my system in the same setup (3x230V, no neutral, single phase ESS)
