MPPT limit charge power instead of exporting to grid

Hi, I have some problem with ESS

3 x MP 2 + 1 Fronius symo 5 + 2 x mppt

When charging phase switch into absorption or float then MPPT limits power from PV instead instead of exporting to the grid. It is quite strange because it is wasting solar energy;)

There is no additional limits in configuration. It looks like ESS use power from Fronius to charge battery (higher priority?) and limit mppt charger.

after few minutes MPs charge bateries from Fronius instead of from MPPT.

I have found similar problem on forum but there was information that problem has been resolverd year ago. All devices updated last firmware.

Did you find a solution?

I had this working in earlier Version of Victron, but since an Update it does not work anymore and I cannot find a good solution ndoe this. My grid Export is limiter by a fuse from the grid-maintainer, so if i do not Limit my Export proberly, the fuse drips.
