Can I run three big freezers off of this? Can I plug them all into the generator?

Asked by Birdie March 22, 2021

Answer

Since each application is unique, we are unable to properly size a unit remotely. We do have a sizing calculator online that can help you get an idea on what generator may be needed, but we strongly recommend working with a dealer to ensure the proper generator is picked. Our sizing calculator can be found here: https://www.generac.com/for-homeowners/home-backup-power/build-your-generator, and all of our local dealers can be found at www.generac.com/dealer-locator.

What is the decibel rating for this model?

Asked by Hunter March 18, 2021
1
Answer

Because there is no industry standard way to measure sound output on portable products it makes it very hard to compare brand to brand. Generac does not list the specific decibel level for our portable products for this reason. This is an open engine similar to a lawn mower so it does not run as quiet as our automatic home standby generators, is comparable if not quieter than most other brands.

If I use this to power my panel through an interlock via 50 amp outlet that i had installed-do i need to ground this gen to the house grounding rod?

Asked by DA February 18, 2021
1
Answer

Your 50A. outlet has to be a 4-wire outlet (2 hots, neutral, ground). Your wire to the generator has to be 4-wire (white, red, black, green) and rated for 50A or more. The ground wire in this system is carried from the generator to your panel through the wiring that connects them together. Your main panel is grounded to a ground rod, and is therefor connected to the generator through the green wire, and no other connection is allowed or needed.

This is a great product. It is just the right wattage for my needs. It's the right size and weight for me to move it around easily and it's fairly quiet. I've only had it for a week but I did have another Generac generator in the past and it was totally reliable. I keep it in a 3' x 5' shed and leave the doors open when it's running. It certainly meets my expectations.

After doing some extensive research The Generac GP 6500 is a top quality Generator for all your power needs. Whether your a contractor or home owner looking for an emergency power source this generator fits the profile. It is a pull start motor and started on the first pull. Instructions on assembly and operation are clear and easy to understand. I took me about a 1/2 hour to assemble with some sockets and wrenches. Your pretty much assembling the handle and wheels. Everything else is factory assemble and ready to go. All you have to do is add the provided engine oil and add 87 octane or above gasoline. On a test run I was able to power my interior lights, 28 cu.ft.refrigerator, 7.0 cu. ft. freezer and according to my calculations should have plenty of watts to fire up my oil burner and Amitrol water heater. For a more permanent solution I have purchased a Generac Home Link Transer Switch. Highly recommend this generator.

Generac builds a first class portable generator. This unit is simple, but packed with the features you really need. It is manual start with a recoil pull cord. Mine started on the very first pull. The unit requires very little assembly, just the wheels and handle to attach. You do have to add oil to the crankcase before the first start, but they include all the supplies to do it. Comes with a 1 liter bottle of startup oil good for the first 30 hours. Also included is a funnel for adding the oil. Very thoughtful. After that, use a good synthetic oil and change after 100 hours. Uses regular gas, 87 octane. Has a runtime clock and alarms to alert when service is required. Five separate electrical outlets with separate breakers available for the loads you need to supply. Instruction book includes a guide to determine how much load and how many appliances you can run simultaneously. This is a high quality unit.

The Generac GP6500- 6500-Watt Gasoline Powered Portable Generator is a solid performing back-up power unit that has been easy to start (usually 1 crank), is very portable, runs smoothly under no-load and loaded conditions and offers a top tank gas gauge that indicates remaining fuel left. With a 10ft 10AWG NEMA L14-30 Cord, a NEMA L14 weather proof internal installed outside Plug and a NEC Article 702 ANSI\NFPA 70 generator 2-pole El. Panel Interlock kit, was able to provide whole house generation (with minimal power management) while running a 12K BTU window unit, 2 refrigerators, 1 freezer, a gas dryer and all of the lighting in a 2800sf home! From unboxing the GP6500 to ready-to-power the home only took an hour for wheel\leg, dual carry handle installs, adding engine oil (1L provided) and gassing up the tank! After powering our home for 3 hours for generator break-in and testing power usage circuits, under no-load conditions closed the gas tank valve to allow the carburetor to run dry...now ready for monthly test runs or future power outage emergencies!!

It was very easy to put together and it started up right away when I tested it. It handled everything in the house. We have a total electric home. Only problem we had is I ordered a Generac cover after double checking with the person that it would fit. It did not. We purchased a barbecue cover a 52 inch grill and that worked perfectly.

I bought this model back in 2005 after the 2004 hurricanes hit Florida hard. I really haven't used it until now other than to run it periodically to make sure it fires up when needed. I've kept fresh fuel in it and always shut off the fuel valve and let the carb run dry when I'm not going to run it for a while. Hurricane Irma hit Florida last Saturday night. I've been without grid power for a week now. I've got this generator hooked up to my house using a range cord on the 50 AMP outlet to a sub-panel. It is doing a great job at keeping my well, lights, entertainment and air conditioning going in my home. As hot and humid as Florida is at this time of the year, we would be miserable without it. I tried to sell it a few years ago before I moved back out to the country. I'm glad nobody wanted to buy it at that time because I'm really happy to have it until my power is restored.
