I did not mention the inverter generators as price could be an issue and noise is not .
I bought cheap an old used Yamaha 1000 inverter generator that is still operated a couple of weeks per year to power the cpap machines at hunt camp.
Retired Neighbour used to run it 24/7 at his trailer from spring until fall for over a decade . Very conservative amount of hours would be 7500 and closer to 12,000. Pretty much worn out and burns oil so 60wt Amsoil motorcycle is used . This allows two tanks of fuel can be used without the gender tripping off on low oil level.
Can not see the sense in purchasing a genset that can not carry at least 1600watts continuous .
