Issue with MultiPlus 48/5000/70-100 connected with Fronius Symo 8.2-3-M

I just installed the multiplus on the ACin of 1 phase of the fronius symo with pylontech batteries for backup and solar energy storage.

I.m not allowed yet to feed excess energy In the grid so fronius is set not to feed excess energy In the grid. A fronius smart meter needing installed.


The fronius and multi are connected via venusGX



1. 1st issue is that when I lower the SOC of the batteries the fronius is being throttled down and power is being supplied only from the batteries.

2. 2nd issue with charging the batteries. The fronius will not ramp up to provide additional power for the charging.

Any ideas why this is happening?

I have only 1 multi installed. And I.m leaking power to the grid on the other 2 phases most probably. Not sure how to proceed. If anyone has an ideea.
