Solar priority - for summer

I have a 15kva Quattro with Solar, Batteries and a Generator.

It’s , set up to start the Generator at 6 kva.

I also have a decent 4kWp of solar connected to the system.

If it is super sunny and gaining 3kWp and the base load is 6kVa, I want the system to Use Solar + Batteries until 8-9 kva, and then the Generator....

How do I prioritise this?

Hi @Mister R
Is your solar DC or AC coupled?

Without a Venus Device this is difficult, as the inverter doesn't know how much power the MPPT is putting into the battery.

Your best bet I think is to also use battery voltage as a factor.
