We found that even a well made Honda petrol genset was highly unstable feeding volts into a UPS for a machineroom. They are good at lights. They are good at a cooker. They suck at anything which expects regulated, non-noisy volts.
Lots of homebrew 'you can plug this magick cable I made' methods to supply volts across the fence to neighbours houses when the power goes down are really bad: behind the meter is just as lethal as in front of the meter, if you get it wrong.
