Why is it that even though my battery is 100% charged (99% now), that with a house load of 3kWe, solar generating 1.5kWe, I'm pulling 1.5kWe from the grid rather than from the battery?

What work mode is your inverter set to? It should be Self Use, it sounds like it might be set to Backup?

What version of Master are you using?
I had this problem as well, and it was resolved by downgrading the firmware version.

I've got this same issue too.. how do we go about downgrading the firmware? or surely they'd be an update to resolve this firmware issue?
