He's running TWO ac's from the inverter. I don't think it matters how many batteries you have, that's a lot of power. I'm pretty sure he's not even running the compressor, and it's just the fan as someone else pointed out. It happens on our venom toyhauler all the time.
Btw ... I do find it kinda annoying that the power management system will shut down the compressor if loads are too high but still allow the fan to run. If I turn on all 3 AC units one of those the power management system will shut down and only the fan runs. When I installed my two 3000w inverters I had to trick the power management system into thinking the generator was running by applying 12v to one of the pins on the power management panel. Otherwise, it thought I was running on 30a and restricted me to just one AC unit.
At one point I had the two inverters running splitphase (120v@30a x 2 each shifted 180 degrees from one another). This is how 50a service is configured, two 50a 120v legs 180deg out of phase which prevents the common from carrying the potential 100a combined load. The problem I was running into was that one inverter alone was not enough to run two AC units. That configuration let me run the living room AC on L1 and one of the other ACs on L2. I could not run the two ACs on L2 at the same time. I reconfigured the inverts to be stacked (120v @ 60a shared across L1 and L2) and can now run any two ACs. The power management system and the 50a breaker I have on the inverters prevents me from running all 3. But I do have the horse power to pull it off between my two Honda’s , solar and the two inverters.
