Is there any reason to Multiplus II not charging Pylontech Batteries at maximum charge settings?

Configuration
2 paralel Multiplus II 5000/70
2 Pylontech UP5000 batteries
Can Bus Cerbo
DVCC
Update FW

Despite AC Input limit from Grid or Generator allow charging batteries at Max Charging Limit capability (CCL and DCL showed in VRM), real behaviour is that charging current never achieve Limit and keep below 10 to 25% below limit. DVCC Max Input AC and Maximum Charge Current are properly configured, but charging current doesnt achieve CCL and AC Input current keeps below configured limit.

Multiplus Charger is set to Adaptive+Batterysave, but I read that these settings should be ignored if DVCC is in control
Any comment on the issue?

If you're not getting the max charge rate, chances are there's either high resistance, batteries not accepting, ac input being restricted.

Actual numbers through the whole system would help a lot, as well as a screen shot of your charging settings.
