MPPT - Separate Battery Charger Managment

All,

I have an MPPT and an inverter/charger. When connected to shore power, how can I adjust the settings so that the inverter/charger only activates when the MPPT stops working (no solar input), or when the battery charge drops below a certain voltage, say around 30%? My goal is to prioritize using solar energy and only switch to shore power if there’s no solar input. I believe it’s possible to configure the charging profile to achieve this. I’m working with a 200Ah lithium battery bank.

thanks,
Marcus
