What will a 1000 watt inverter run? Not a hair dryer, toaster, micro.

Wondering about that. Our new hair dryer has a low power setting that uses ~670W. Haven't tried it yet with our 1000W PSW inverter, but hopefully it works without blowing that expensive 75A DC fuse.
It would definitely be preferable to turning on the furnace and kneeling on the floor next to a vent, or turning on propane range and roasting my head over it (covering the flame with a cooky sheet).
I imagine the batteries will have to be well charged though, as I still only have 220AH in 2x6V GCs. The voltage drop could be substantial.
Once we get our tongue weight limitations fixed, I aim to replace those batts with a set of 4, doubling the AHs. Haven't decided on 6V or 12Vs yet, but will avoid AGMs as we're hard on batts. What with no generator, but 700W solar, they can be undercharged for days at a time when the weather/season is off. Like/need to equalize them asap afterwards. (Sadly, LiFePO4 is still too expensive for us).
Good, true deep cycle, flooded 12Vs might be the best replacements as our inverter usage seems to be increasing. Might even get a 2000W inverter some day!
I have a Xantrex PROwatt SW 1000 sine wave inverter wired with 6' of #0 wire (through a 150 amp fuse) to a pair of Interstate GC2-XHD 6V, 232 amp hour batteries charged by 355 watts of solar panels (usually skip the portable panel & only 195 watts during the high angle sun during the summer).
For breakfast, I can make 5 cups of coffee with a 600 watt drip coffee maker & toast an english muffin after drawing down the batteries by 25 amp hours overnight. I may get a couple of alarm beeps from the inverter towards the end of the coffee brewing (a 65 amp draw & about the same for the toaster) & about 10 amp hours draw for both, but the batteries will be back to 12.5 - 12.6V after the coffee is done.
During the summer the batteries are back to full by early afternoon, by evening in winter.
While I agree that a pair of 12V batteries with the same amp hour ratings as the 6V batteries would make the inverter happier, the 6V system works, and is less expensive.
