Understanding battery vs IQ8 options for grid outage backup

Located in Colorado. I’m building a home and as soon as its done this summer I’d like to put in a solar system and I’m evaluating some options for possible backup power during a short term grid outage. In my research the most likely time for a grid outage here is going to be peak heat summer days, where rolling blackouts might be employed here as soon as Summer 2024. For this reason I was researching originally a backup battery like the Enphase 10 but then realized it only outputs about 3.8KW which wont be enough to run even one of my two AC compressors.

Then I started researching IQ8 microinverters which would allow me to self-power during a grid outage. I’m guessing I’ll have a ~10-12KW system so at the peak part of the day assuming no cloud cover or other issues I’m guessing I’ll be able to generate 6-8KW to power the house. That should be enough for at least 1 compressor but maybe both depending on load/timing.

Ultimately I may need both the battery 3.8KW + solar of 6-8KW to fully power the house during a peak heat summer short term grid outage? With the benefit of during non-sun or non-peak heat outages the 3.8KW battery could serve some of the critical loads in the house like a fridge, lights, etc.

Am I thinking about this the right way? What is the right strategy to employ here – especially if I am on net metering, is just the IQ8s in my hypothetical example enough to keep the AC on + avoid peak demand rates?
