Yeah rather stick to sine as I don't want to be limited by what I can run, ex: some motors like it some don't, easier to just get sine and not worry. But modified sine ones can be quite cheap and beefy for same price... so it is an option. Most of the permanent loads will be lighting anyway which won't care about modified sine.
I was looking at this inverter:
https://www.amazon.ca/gp/product/B00AYH6AK8One review does say it runs a 15 amp mitre saw so that is promissing. Using mitre saw as example here as it's probably one of the more aggressive normal tools when it comes to startup load, maybe compressor would be a bit worse. I'd probably be running that and a circular saw. Maybe weed whacker, but probably upgrade to a battery one.
Low 1k range is as high as I want to go though, I would be splurging more if this was for an off grid cabin/house and going with the ferroresonant one though and ideally a redundant setup. One thing I've kinda gave some thought for off grid is that I could probably run a bunch of "grid tie" ones too to add redundancy and extra power. At least I think that would work. As long as the main one is running.
The blow dryer idea sounds interesting too for the saw... maybe I can just modify my saw and add a load coil with a switch to turn it on and then off to start the cut. Or I could build a separate device that it plugs into, that might be a better bet as it will be more universal.
Basically this is more for an experiment, I want to see if I can build my deck with just solar. I think it can be done as long as I get a good inverter. But even after this project is done then I'll probably add various solar circuits throughout the house so be nice to be able to run big loads if I choose to. The solar system is only 400w so obviously I'm not going to run big loads for a long time, but like in an emergency I could probably still run the microwave or something for a few minutes.
