It was up and running 20 minutes out of the box. This generator delivers more than enough power for my home during blackouts. Having the 240 output gives me even more options. And having a remote control, well that's just cool to have.
User manual says not to run unloaded for "extended periods" [ not sure how long that is ] to prevent engine damage, and there is no auto idle. I have a Genrac that is less then half the size and 20+ years old and it has it. I think it would good for economy and noise, and apparently engine life. Just got it today, and have not even put gas in it yet, but am trying to get to know the unit read and study the manual before I do something wrong. It look like a super addition to my home, super friendly so far.
