Hurricane Power source

During the recent power outage caused by Hurricane Sandy we used our GP7500E to power our entire home through a transfer switch. Refridgerators ( 2) , sump pump, Fan for gas heat, lighting, bathrooms , TV, kitchen appliances all working no problem. Unit ran 12-15 hours a day for 7 days. Changed oil at 32 hours then every 50 hours after that. Great unit. Purchased unit during the summer and this was the first big tryout. It passed with flying colors.

We trust Generac to provide well made, reliable equipment to protect and serve our home.

Our portable generator is the perfect size for our current home needs. We purchased it to run our home in emergencies. We have lost hundreds of dollars in freezer food in the past due to outages. We bought our portable Generac to make sure we can function in any kind of emergency; at home or, if we have to relocate temporarily for some reason, it can go with us. We also plan on getting a larger permanent Generac in the near future, to monitor our home all the time and run it when needed. We trust the Generac name and feel safe and protected knowing it is here.

It does what it's supposed to

After 35 years at the same address and typically dealing with 1 or 2 mostly short outages per year, we experienced an 8 hour outage and a 5 hour outage within 2 months. My wife said we need a generator! We looked at whole house backup but that seemed like overkill and very expensive. After lots of online research we settled on a Generac in the 6500-8000 watt range. Because we have a well, we needed 230v output. The price difference between 6500 and 8000 was so small, we opted for the GP8000e. The installer put a lockout on our electrical panel so we can switch between generator power or electric service but the generator cannot backfeed the incoming electric. Yesterday we experienced a 5 hour outage. After 30 minutes, I rolled the generator out of the garage and onto my patio. It fired up with electric start even though I had not charged the battery since the initial startup 4 months ago. I hooked up the 30amp cable to the receptacle on the house, switched the lockout on the service entrance to generator power and we had power. In addition to the well pump, furnace fan, and fridge, we ran the microwave, an electric cooktop (not at the same time), and all the lights we wanted. My only complaint, though not unexpected, was the volume. It is loud! My phone sound meter app registered 90db at about 10' away. It was about 8' from our family room and even with the windows closed, it was too loud to watch TV comfortably so we retreated to the basement. It's also quite heavy but I had no real trouble wheeling it around the house from the garage to the patio. Overall, I'm very pleased with it and my wife was happy that we had water and a cold refrigerator during our 5 hour outage.

Great value

Bought this product as emergency back-up generator for home to provide power to refrigerator/freezer and well during outages. Excellent value and dependability. Will upgrade to home standby generator next year to power whole home and move this to garage for powering tools.

Excellent!

Ran this generator for almost 5 months everyday after Hurricanes Irma and Maria. Was the only thing that kept the family from going insane. Absolutely trustworthy and it never skipped a beat. The electric switch stopped working but with the manual start we never went a day without power. Heard a lot of people complain about their generators but we never had a problem.

Life saver during power outage

We was dealing with a major power outage, after looking at several other brands, I went with this brand and size, because everything I have heard, I trusted it. This unit was perfect, it provided power for my side by side fridge, and two upright freezers with plenty to spare. While others were sitting in the dark, we was sitting in a well lit living room eating supper. Love my new Generac generator.

Very nice generator for a great price!

I researched generators for a while and this unit is perfect for what I need and the price was excellent. I set it all up and tested it out, everything works fine. I don't really want a storm or power outage but until that happens, I haven't fully tested this unit yet.

Easy Start, Easy Connect, Generator and CO Protection!

A Great Friend brought me a Generic GP6500 he just bought that he only used for 2 hours. My Coleman hit the dust during the heavy rain of Florence. House was wired for generator and the GP6500 powered my freezer, refrigerator, lights and a portable AC unit during Hurricane Florence. Power has been out for a week with no problems. Rated at 40 amps the breaker lets you know when you are turning on to many circuits that add up quickly. Using LED lights through out your house helps on the wattage load.

Cranks easy

I bought the 6500e to run my heat pump, I have a generac 17kw standby unit but the guy that hooked up find the wire the heat pump in and was less trouble to wire it outside for a portable unit. This unit fires up in a half a turn with the electric start and pulls the heat pump with ease!

Dissapointed with dealers / service reps in CT

I purchased this unit (GP17500E) for home backup power for my CT home. I have been trying to get a dealer / service rep to assemble the unit at my house - for a fee- and spare me the effort of having to lift a 400 pound unit to assemble the wheel kit (I have a bad back)....So far all the service reps in CT have turned me down. One told me they are not taking any more portables...Just be aware that if you purchase this product you'll be on your own trying to assemble it...
