This generator is really nice and powerfull.

Live in northern Florida, city of Ocala out in horse country and our power grid goes down at least once a month and we also are affected by hurricanes. This generator will power your whole house if required, starts easy, runs quiet for its size. It's real heavy to move around but manageable, I am using the 30A and 50A outlets in tandem to feed my single home electrical panel because the single 50A only gives you 12KW of usable power.

Generac Stood Out against the others

After going few days without power we decided to start shopping for a generator. I looked at many different types, makes and models. Generac stood out in the reviews I read in terms of function and reliability. I found the information available on the Generac website helpful in determining what type and size generator to purchase. Should I need service there are many authorized service representatives in my area. This too has been a discriminator in choosing Generac over some of the other brands. Assembly instructions were clear and the quick start instructions are an excellent idea. It took no time at all to assemble and start the generator. I choose to buy a portable rather than stand-by so that I can have power to do remote construction projects. I'm happy with my choice so far. I'll follow up later after I've had an opportunity to exercise the unit.
