Generac 6500

I had previously owned a Generac 6500 and needed another unit due to the worst ice storm to hit in decades. I found a unit 3 hours away. It was worth the trip. I cut open the box, added the oil, handle and wheels. Put gas in the tank, and it fired up on the first pull. Quality I knew I could trust. It was worth the trip to bypass the lesser known brands.

Great Portable Generator

I have supplied the house through 3 power actual outages since 2013 Dec for short duration's under 12-hours. Run the GP1750E every couple months to make sure it works when needed. Starts up on no more than 2=pulls / and right away when using the electric start. Load Test Run with 3-HP LPAC [Low Pressure Air Compressor 150 psig] for the sand blaster and other lights and equipment in pole barn. Also run Simulated Power Outage Load Test to supply the house VITAL LOADS connected to our 100 Amp Sub-Panel Load Center about 4 times a year. [[Main Breaker Panel is 200 Amp --- Sub Panel is 100 Amp for fuel-oil heat, well water, sump pump, electric water heater, freezers/refrigerators, appliances in kitchen, various lighting circuits.]] Have TV, Computers, MODEM-Router, Printers on their own UPS [Uninterrupted Power Supply] to give me time to setup generator to supply electric to house. Can set-up and power house in about 5-10 minutes. Great Generator for the $$$ --- only regret was I didn't get a 15-KW Generac automatic Stand-By unit --- but I live in the rural area without natural gas and didn't want to invest in propane just for a generator.

I believe it is the best value for the money.

This unit is very easy to set up and use. Ran the electrical system to my breaker box and it does an excellent job. the exhaust is a little noisier than I would like but well worth the money. Very neat machine and no rattles. I would like to see the battery cables re- configured to make the battery easier to hook up because I keep the battery in our home where it is warmer. Maybe clamps instead of the small bolts and nuts for the positive and negative terminals on the battery.

Smooth as Silk!

Two weeks after installation of the generator and the GenTran switch we were hit with the "great November snow" in New England. Some people in CT were out of power for 9 days or more. We were out for the 10 minutes it took for me to wheel the generator out, plug it in, start it, and shift circuits to it. SMOOTH! Never a hitch or a glitch. I LOVE it!

Recommend the GP8000E to power a home

The GP8000E works well for running our whole house. We had an outage for 2 days and were able to run our whole house without any issues. We have a well water pump, AC, refrigerator, freezer, lights, etc. We did not encounter any issues. The portability works well for moving and storage.

Works as expected, very happy

Purchased for house backup. Needed portablity with power for my situation. Unit performs as advertised when tested at 12kw , no-load to full load and v-v <3% voltage or freq variation w/ <5%thd. Runs my 4ton ground source heat pump ( has soft start) and 2 refrigrators plus rest of house minus range and dryer easly using the 50 A. connector. Power is clean and well regulated for sensitive electronics in house. Portablity is good since i lift it with tractor loader to move from house use to other areas. Thanks.

Very useful

[This review was collected as part of a promotion.] This generator is easy to use and is very convenient. Yes, it takes up some room in your garage and you might not use it frequently, but in Houston hurricane season it is worth it to be prepared. This won’t power your whole house, but it will keep the refrigerator running and a couple other things powered in the event the electricity goes out.

Great generator for power backup

I purchased the GP7500E to replace a smaller 3250 generator to provide backup power for my house. Last December we had a power outage in the middle of a winter storm, the smaller generator worked for a few items, but I wanted to power more circuits in the house. I installed a transfer switch so I can power the furnace, refrigerator, TV, computer and several lights in the house I assembled the generator, added oil, gas and connected the battery. It fired up right away! I definitely like the battery start! I did a test run on the house and everything powered up as expected, now to wait for the next power outage.

Generac is #1

Gererac was my first choice, spent a lot of dark days before I purchased the GP6500E. Plenty of features, easy setup. I chose this model especially for the Electric Start feature, and the efficient fuel consumption rate. I also matched this generator with the Generac Transfer Switch kit.

Amazing quality and great value

[This review was collected as part of a promotion.] due in no small part to recent events on the eastern seaboard, we felt it necessary to purchase a portable generator given to volatile weather here. we decided to go with the best name in the business: Generac. we were certainly not disappointed. the 8000 Watt Standing and 10k Startup wattage were plenty for our home. that and the Package coming with a Battery and an electric startup were all key features that pushed us towards this brand. we did not have much knowledge in Generators and even less in hooking them up. I love the 25 foot chord it came with and also the ease at which it is transportable via the super heavy duty tires. we went with a professional to hook everything up which cost about 200 Dollars. though I could have probably done it, as the directions were super easy and everything was marked and easily understood, we felt having someone with experience to install it was wise. overall we are very happy with this new model and even happier with the performance. it is not loud (like a Starship taking off) as the exhaust is pretty well muffled. love that feature. we recommend this to anyone with potential power issues.
