Just runs and runs

I'm no Nor Cal and have been experiencing the PG&E Power Safety Shutoff. My neighbor had one of these 8000's and I was fortunate enough to find one as well. Electrician came and wired it into my panel and wow...my whole house just runs like it's on PG&E. Some little weird stuff to get used to, like when the well kicks on, the LED lights in the kitchen flicker for a second but no big deal. Hot showers (propane hot water heater), lights, etc. I go into a room and turn on the light...just like normal. Only complaint is it's loud so getting it away from the house is important but we just close up the windows and deal with a bit of a hum to have power.

Amazing

[This review was collected as part of a promotion.] This Generac Generator is amazing!! We live snack dab in the middle of Florida and get so many hurricanes each year. This powers most of our home and runs for a long time. Highly recommend this generator!!

Delighted

Just received the new GP1800. It was easy to setup, manual is easy to follow with good diagrams and explanations, and above all it was easy to start. We have been hit with some terribly bad weather this winter (and flooding in summer) and I was determined not to be without power again. This unit will provide enough power for the primary needs. Wish it had a couple of more outlets but will manage fine. It is reassuring to have a good unit like this always available for use!

Reason to buy product

We bought this portable generator for the pending hurricane season. Nothing worst than being in a home for 1 week without power to run refrigerator and freezers. We researched and found Generac to be the best generator on the market. Hopefully we will not need it, but it's nice knowing you are covered if you do.

I love it.

I bought it almost 2 years ago, I haven't had to use very often, only when power is going to be out for a while, but it runs EVERYTHING in my home. No need to shut of anything, just hook it up, push the electric start, and throw the switch in my breaker panel. It's not one of the quiet ones, so I keep it about 100 ft from my home inside my barn and I don't hear it at all.

This product quit working

It only ran for 4 hours and stopped producing ac power to our house. When we needed it, it failed. I called and was given a number of a dealer that could fix it. It is now in the shop. I am waiting for it to return, fixed I hope. After my experience with this generator I would NOT recommend anyone buy one.

Co sense is garbage

I only have two hours on mine, however my bro-n-law bought one same day. He put 52 hours on his and it quit running. We brought it back and they told us we were the 38th returned generac that day. They said the co sensor will not reset so that's why they stop running. It was outside in the yard, not inside....so yeah. Safety features aren't safe when you have an elderly mother about to die from Louisiana heat and you depend on a generator and a window unit. Now question is how long will mine last, I have power back and won't know until or next hurricane. Mom-n-law surving off my coleman with Subaru motor that I bought during Katrina in 05. Almost 20 years old and still running like a champ. This generac couldn't make it 52 hours.

Bring on Winter

[This review was collected as part of a promotion.] We live in the country and we have had some hard winters when the electric has been out. We have been wanting a generator for a good while, and finally got one. I didn't know anything about this brand, but "wow"! It had very little assembly out of the box. It is very sturdy and came with large wheels and a handle that uses both hands to keep it balanced, which makes it easy to maneuver. The handle locks in place and folds down when you don't need it. I was really surprised at the features it had. It had 4 plugs, and a 220 volt plug for larger appliances, like a washer or stove. Of course it's not winter, but when the power goes out we will be ready! We hooked it up to our power washer and was able to go beyond what we can usually do around the house. It started with the first pull and had the power to run various items that we tested it with, such as the power washer, welder and we even plugged it into a small camper to run the lights, etc. We are almost wanting a hard winter, just so we can use it. I am very happy with this generator and feel that it will last a lifetime. There is nothing flimsy about it and I think they thought of just about everything with this. I realize we didn't get to try it out for very long, but I can't think of any cons to this generator.

Better than the rest.

After extensive research, IMO this unit has all the spec's I require to run my home in an emergency power outage. After Irene and Sandy leaving me out of power for a combined 25 days, I don't have to split wood any more. This unit was more than adequate for running the 240v essentials in my home, furnace, water pump, water heater and my son's fish tanks. I suggest getting a unit that is a little more than you need. This one is 50 amps, My new GP15,000E was a lot quieter than I expected and the idle switch is great, only runs engine to speed as power is required. Generac should do a DB sound test on these units and post the results as it would no doubt better persuade folks to purchase these portable generators. It should also come with 4 locking wheels.

Ample power and easy start

[This review was collected as part of a promotion.] This generator is perfect. Has a quick start button to make it easy for me to start. It operates off gas, propane or natural gas. It is quiet during running which is a great plus. Has a handle and wheels to make it simple to move around to where it is needed. Large enough to keep me in civilization during power outages.
