RV Plugged in to AC - Want to Prioritize PV and DC inverted power to specified SOC or Voltage

Hi All - 

I have a reasonably stout power system in my RV, 1600W of PV panels, Midnite classic 150 CC, Victron 24/3000 inverter 450Ah @ 24V of Lithium based battery, and the miscellaneous other parts to make it work. 

As summer kicks in in the southwest it is getting hot and AirCon is a must. With my system I can run the AirCon for about 8 hours from 90% SOC to about 35% SOC in my battery bank, and then I want the AC power I am tied to to kick in and start running AirCon and other AC loads and if there is amperage left over start charging batteries. 

Victron as a supplier is AWFUL at helping customers, we might as well not exist; they push you to a dealer that may or may not be helpful. So I am reaching out to the community for suggestions, maybe someone has some Victron experience ? I have RTFM, and it was not much help. I would be grateful for the knowledge and insight this great community might have.

Cheers !

    if you have grid/shore power, isn't it cheaper than cycling your batteries ?

    @mike95490, Honestly I haven't done the math, but it probably is cheaper to just grab grid power. Now look what you have done, I have to do math...
