Lots of questions about what they're doing with so much power, but it really isn't all that much, especially if you want HVAC.
We have 2925W of solar and 22.8kWh @ 48V (equivalent to 1800AH@12V) LiFePO4 and I know of a few with larger systems. We run our AC and/or heatpump via thermostat while boondocking (30K mini-split) and only run the generator on rare occasions of extended inclement weather. So I'm not sure what that one guy is doing, but that's what we're doing with a fairly sizable (but definitely not the largest out there) system.
Even with the size of our system, the math doesn't work out if you have rooftop AC units.
Right now we're also providing power to a neighbor's rig that is having issues.
