@Hawaii Sloper and I upgraded from my DIY power setup from the previous years.
Picked up a DJI Power 1000 (1024wh) and a foldable 200w solar panel
Its a little different than other batteries of that style. Had to buy some adapters for things i wanted it to do, like xt60, car accessory and solar input. But it was on sale for like $400 so pretty awesome.
Its kind of crazy, it can output up to 2.6kw. Its actually the fastest way to recharge dji drone batteries i guess. It has an alternator charger you can get that will do 1.3kw back in. So full charge in 40minutes.
and you can hook up to 6 solar panels into it at a time for 800w input total.
Based off my testing it should power the iron for 5.5 hrs without any power back in from solar.
Assuming we have clear skies somewhere near our tent that should keep up with the iron usage.
@Red already volunteered generator usage too, i think it will do 50% charge in an hour.
mainly though im looking forward to not almost throwing out my back everytime i have to move that stupid car battery.
