1x Multiplus 5000/48 VRM Shows wrong Values

Hi,

got a question, i run a single phase Multiplus 5000/48 in a 3P Country (Germany). As Energy Meter i use the EM24 and VRM shows the following:

As you can see the battery is discharged with 2.7kw, Grid shows 14, but the total loads is way too much. It seems the L1 gets added or so?! Any configuration i missed? Thanks

Phase compensation means it tries to make the total close to 0W.


Look at the individual phase values not the main total for grid as @Matthias Lange - DE suggested it will make more sense.

Did you check if you were actually feeding back on L3?

Yes, we have another grid meter. this we read with loxone home automation.

The Setup is as follows:

grid -> EM24 -> Victron -> SDM620 Meter -> House

I have the same setup with 3x multiplus II for the three phases, there everything is correctly calculated.

There one can see the Critical loads are close to Battery Discharge.

At first I thought it was the ET340, read something about 3p and Germany. But we changed it to EM24. But same result.

You have a load of 3284W on L1, 808W are coming from the grid. The rest of 2476W is coming from the MultiPlus. To deliver the 2476W the MultiPlus has to pull 2711W from the battery, that's an efficiency of around 91-92%.

Du hast eine Last von 3284W auf L1, davon kommen 808W aus dem Netz. Der Rest, also 2476W, kommen vom MultiPlus. Um diese 2476W liefern zu können zieht der MultiPlus 2711W aus dem Akku, was ein Wirkungsgrad von etwa 91-92% entspricht.

Hmm but the values are wrong. The AC Loads should show something around 2800 W and not the 3284W.

Effizienz war nicht so das Thema, mich interessiert jetzt eher so wieso er das halt falsch anzeigt?

Er zieht ja gerade im BIld nur 14w aus dem Netz und keine 808w. Sieht man ja auch am Grid.
