I have found that many square-wave inverters will not work with a microwave, as it needs to full peak voltage to run the magnetron. A microwave is actually very efficient in that almost all energy is used to cook. I had a 'turbo' microwave that is both a microwave and a turbo-oven, so both very useful and efficient for cooking. Anyone use one of those?
I have a microwave pressure cooked, Nordic something, and it works very well and is very efficient. Anyone use those?
Any 12v microwaves? I was working on building one, seems straightforward to me, but testing with 2000 volts was putting me off!
The 'turbo' microwave was not an above range model, that seems like what would work best to vent outside, I read everyone talk about how this is an issue when cooking inside a small space, and seem to depend on their ceiling fans for this. I don't plan to have one because like a boat I don't want holes in the hull, and for a camper, don't want any holes in the roof. ;)
