I have a residential Solar system with batteries. Most days the grid is not needed and the inverter statistics show zero energy purchased, however the electricity provider's meter, and my own independent meter shows that I'm purchasing around 1kwh/day. I've been through all of the inverter settings with my solar installer and we can't find a way to stop the power draw, without physically throwing the main power switch. I'm looking for a way to automatically cut the mains power based on battery charge. For example, disconnect from the grid while using PV or battery, when the battery gets low and there is no sun, reconnect to the grid until PV or battery is available.
I was thinking of a solar charge controller with contacts to control a contactor, or an ATS (I have an ATS that isn't being used) using only one input of the ATS and the other input with no connection. The problem I have with these options is I can't find a solar charge controller with load output controllable by battery level.
Is this a viable option, or is there a more suitable option available?
