I am NOT fond of the Chinese generators, the AVR is lousy and problematic and the generators use brushes.
For low power less than 10 KW one may think about a 20-25 HP motor and convert it to a generator. Or to buy a brushless American, European or Brazilian generators. An ELC will be required in any case to maintain the output voltage regulated and/or the frequency.
