I've just remembered an old inverter that I'd forgotten. It's was made by Avel-Lindberg and made 200W at 240v from 24vdc. It has a fairly hefty transformer in it, and a set of 2N3055's on a big finned heat-sink. Weighs about 30lbs. I used it last in 1987 after the gales, when the power was on/off/out, to run the C/H electrics. I think I'll dig it out and start playing!

Of course it'll work. (It hasn't caught fire yet).

Oh boy.  The transformer will be so well made, sell it quick!  Those 2n3055s will be cooking at full load, dropping the efficiency right off.  Probably bullet proof, though.  Takes a lot to kill those transistors.
