Until the app updates to this new look my system was working great. But now I'm getting power bills and its not wiring how it used to. I have 2x5kw hybrid inverters each with 22kw of batteries. We have cheap power from 11am till 4pm. I have force charge set for this period and grid charging enabled. It starts charging at 11 am as expected and finishes filling the batteries mid afternoon at some point. Horace as soon as the battery is full the related inverter turns off. Eventually both inverters turn off and no solar comes in and the system sits idle until 4pm then goes back to normal. Previously it would run the house from solar and export to grid. Now it just powers from the grid until 4pm hits. I've rebooted the inverters. Updated to newest firmware on everything and still no good. This is frustrating the he'll out of me as my bill went from 30$ a month to over 200!
I had my battery system installed in March 2026, and it has been operating exactly as you described from day one - PV is disabled after the battery is fully charged during "Force Charge". To maximise the benefits, I have to manually switch to “Self Use” or “Back-up” after the battery is fully charged each day, clearly not ideal.
I am unsure whether this is a firmware bug or intended behaviour by Fox. However, I cannot see any reason why PV should be disabled while I am purchasing power from the grid. It is good to know that the previous system strategy was more “clever.”
There are some similar discussions, but there does not appear to be an easy solution so far.
