Also - some boiler pcbs are not well designed (to say the least) -

"dirty" mains might kill the pcb, be warned

I know inverters don't produce a true sine wave

Some do, some produce a "modiyfied sine wave" others are square wave
releying on the connected kit to "shape" it.

- but wouldn't a basic generator be pretty good if kept within its
ratings?

Probably but when a (reactive?) load switches off (ie a motor) there
can be quite a large voltage spike until the genset throttles back.
Similary when a load comes on a dip until it throttles up.

Not quite like the gensets we are used to Dave, 100kVA with only a
30kVA load, even banging a 5k on is taken up by the fly wheel... B-)
