Can’t prevent overnight battery charging
Posted: Wed Mar 18, 2026 8:08 am
I’ve had an installation with a Fox H1-G2 6kW inverter + EP11 battery for more or less an entire year now. Early on, I set the battery to be force charged 00:00-07:00 every night using the ‘Charge From Grid’ settings.
This has worked perfectly, but I’ve reached a point with my import tariff where it’s no longer beneficial to do this. So for the last two weeks I’ve been trying to stop it charging - I can’t do it!
I’ve tried:
- Turning off the Charge From Grid Setting
- Wiping out the times on Charge From Grid even though it’s disabled
- Setting Charge From Grid to be 00:01-00:02
- Modifying the tariff setup in the app in case that was causing ‘intelligent’ behaviour
No matter what I do, including using HA to force a max SOC cap, everything is overridden and it charges from the grid 00:00-07:00.
What am I missing??
