24v is a whole lot easier on the amps draw. Should be fine for a few minutes' use, but I woudn't be firing up the a/c just yet.
By the way, what are you using for charging?
Yes, with 24V, I like the fact that I can double my Inverter wattage and not have to touch the cables.
But another good reason for switching to 24V was my 30A mppt solar charger. With only 12V at 30A I wan't getting the max possible peak A out of my 700W of solar. Assuming 90% efficiency, 0.9*700/24V = 26A, well within the charger's 30A (actually >31A) limit. Or I could even add ~125W of matching solar if there was space.
We're charging only with solar for now. No generator. We go for days boondocking, sometimes only partially charging the batts with 700W solar. Then when I get to shorepower, the solar is used solely to recharge and possibly equalize the batts. With 12V batts I once or twice used a 120V battery charger to supplement the solar, but it really wasn't necessary.
The Rogue solar mppt charger is so much more sophisticated than most 120VAC chargers that I'm spoiled. If I do need a 120V supplemental charger in the future, I'll probably just get an adjustable power supply that can go to 32V.
