   Utterly befuddling.
   
   Double-conversion UPS manuals that warn not to use with an alternator generator. Other equipment for power correction by the same company carrying the same warnings.
   
   wtf is one supposed to use then? Are they just expecting one to melt the generator for scrap and buy an inverter one instead?

     @lispi314 They have junk filtering, therefore you can only supply power with an inverter generator.
     
     There is the option of putting a power conditioner in between, but those are is expensive.

     @lispi314 I guess for really dirty power they can't do much and therefore they say not to use it for that, so you can't come back and complain that their product doesn't work and you didn't tell them.
     
     A double conversion UPS converts to DC to remove noise etc (decent quality DC convertors don't really care what power or what frequency you give it), thus if it doesn't work with an alternator generator, it's junk.

     Yeah, in theory and practice that should work, but I'm weirded out by the manuals for conditioners warning against that use. Whatever else do they expect them to be used for?
