It varies. Most of the time, the 3kw inverter generator I already have is fine, but I occasionally need something bigger, and usually hire one in the 15-20kw range. Fine for planned stuff but not very useful for un-planned.
If I could DIY one cheaply using an existing engine and a suitable s/h alternator then great, but that size generator are expensive to buy, especially for only occasional use!
