I'm trying to use ESS "Keep Batteries Charged" mode but want to make sure my Multiplus doesn't use the grid to charge the batteries (i.e always prefer solar).
I've disabled the "charger" from VEconfig and confirmed it is indeed disabled :
However, this has had no effect - the Multiplus still uses its charger to charge the batteries (when there's no sun, which I don't want).
How do I ensure the multi's charger is *really* disabled?
Any ideas?
I have DVCC on (so there's no option to disable inverter charge current unlike when DVCC is off)
My overall setup is..
- Multiplus 48/3000
- MPPT 150/70
- BMV-702
- 48v 200ah lifepo4 (custom built, third party bms, no connectivity to VEbus) - so ESS is setup with "LifePo4 with other type BMS"
