ESS Single Phase grid feed-in not working

Hello I have an EM24, Multiplus2, cerbogx and a mppt 150/70.

The MP2 is connected to L1.

If I now switch the ESS grid metering from inverter/charger to the EM24 and 1000 watts are consumed on L3, for example, it starts to feed into L1. But I do not want this. It should only feed into L1 if enough is being consumed here. Gridsetpoint is 100W and it makes no difference if I set Multiphase regulation to Total of all phases or Indivbidual Phase.

Grid feed-in is completely switched off.

EDIT:

I have checked in: https://www.victronenergy.com/media/pg/Energy_Storage_System/en/multiphase-regulation---further-information.html that With the "Single Phase" option selected, the (single phase) ESS uses the battery to balance only L1 to 0W. L2 and L3 are visible on the CCGX but are not used by the ESS in any way.

This is exactly what I want. But it doesn't work like that...

Please help. Thanks
MrYoshii

Hi. Complex issues are not easy to triage on the internet. As much as victron staff frequent this forum, it’s not an official support channel, that only happens via your distributor.

Sometimes you get lucky, sometimes not.

Have you changed the phase compensation setting?

do you mean this setting?
I have tested both, but I still get a -500 or -1000 watt feed to L1 when 500 or 1000 watts are consumed on L3.

I don't know why but I have activated everything again and now it no longer feeds in when power is needed on l3 or l2.
