Thanks for pointing out that the SUB does not only use PV when there is enough PV to cover the load.  As said that is not what one would have believed.

Yes it made thing how many ppl that dont know to tinker in settings are still using utility power when they shouldnt.

Hi, Tnaik

Did you ever get a fix for this issue? I have the Kodak 10kW model, and does exactly the same.

Considering to use 3rd party (Solar-assistant) on a rasberry pie, to be able to use SOC for changing between Line and Battery mode. Hope it will fix this issue as well?

I have it set to solar+utility but utility never charges batteries unless there is zero power from solar, if i use USB than utility  charges batteries at the same time as solar, why not with SUB though? 

The whole SUB mode isnt working as i was thinking it should work.

Hello, 

Did you find a solution for this issue?

I do not see it as an issue. That's how it is designed. Refer to the charging options as in the manual. In the 1st if you have Any solar it will not charge from the grid.

Hi again,

my inverter is Axpert MAX II TWIN 11KW, I attached the options i have in the charging priority configuration (16).
SNU only works at night when there is no light. during the day, it works as its on CSO which means it only charges from the panels.

and that is the issue.

The problem is stated in the 1st post. When Inverter is in SUB mode it don't want to use the solar power available to power the house. (Mine only do this when the battery reach 100%). Then it's like noon with full sun, and inverter takes all power needed from utility instead of Solar panels. Have anyone tried to upgrade firmware, to fix this?
