Covered outlets provide added protection from the environment and rugged working conditions

Hour Meter tracks maintenance intervals.


1-¼ inch hardened steel tube cradle for added durability and strength

Rated 5 out of 5 by from Great quality product Bought prior to Hurricane Michael. Our home never lost power so we carried it to my wife's mother's house which was without power about a hundred miles from us. We unboxed it and installed the wheels and pull handle which was very easy. Filled it with gas, turned dial to choke pulled once and engine fired right up! Was able to get my wife's 89 year old mother temporary power for her house and well pump. I am very impressed with Generac generators.

Rated 5 out of 5 by from Great machine I use this unit often for the house during storms or at job sites. I purchased a natural gas conversion kit from Amazon and now like during The aftermath of Micheal, it’s running 24 hours a day without me having to refill it with gasoline

Rated 5 out of 5 by from Great product - quality - performance excellent I purchased the RS5500 for use with Hurricane Florence. Put it together, gave it oil and filled it with gas - it started right up on the first pull. Excellent user manual - told me all I needed to do. Highly recommend it. We were without power for 20 hours so I definitely got use out of it.

Rated 5 out of 5 by from One of the best mid-sized generators. We bought this before Florence came, to replace a slightly smaller unit. We wanted the 30A capability, as we’d had a breaker and receptacle wired into the panel box when we built our new home last year. This thing is exceptional. We had used our son’s identical model through two previous hurricanes, and knew what we wanted. It assembled easily, starts instantly, and powers what we need it to well. We alternate between using the water heater, shut it off, then turn on the well pump. Simply staggering things works well. This powers a portable 12K btu a/c, two refrigerators, lights, TV, etc., and we couldn’t be more happy with it. Maybe the best mid-sized generator out there.
