Recently I've noticed, that individual phase regulation behaviour changed. In my installation (now V2.85~1) it was working well till let's say September / October 2021 (V2.7x). Then in winter I can't tell because of low PV power my system does not reach the working point of interest. Now as PV power is considerably higher I see that the behaviour is different than before winter. Maybe it changed with a GX firmware during winter time. That I can't tell for sure because I've not tested with older firmware yet.
What I can tell so far:
Individual phase regulation performs grid feed in and discharging the battery at the same time when PV power and consumption is roughly equal.
When I change to "Total of all phases" the behaviour is immediately better and like it should be.
Find attached two screenshots showing both scenarios where I have tried to catch almost the same situation while the only difference is the multiphase regulation setting.
Usually I have activated the settings "Limit charge power" and "Limit inverter power". For taking the two screenshots I've turned them off to make sure they have no effect.
Now running on "Total of all phases", but would like go again with "Individual phase", so I would be happy if you could have a look sometime. It's not an urgent matter - uufff why I'm writing that? ;)
If testing this issue with an older firmware can help please let me know. For this I consider going back to V2.6x and V2.7x, but rather the latter first.
Best regards
