This is a fresh purchase so have not had a chance to operate it as of yet. Looks to be a well built machine and am hoping for a good experience owning it. My main concern is that I can plug it into my double throw auxiliary power and feed power to multiple buildings. The neutral bonding should allow for this. My past gen. Had neutral bonded to fram and would not function this way without throwing the breaker on the gen.

After going few days without power we decided to start shopping for a generator. I looked at many different types, makes and models. Generac stood out in the reviews I read in terms of function and reliability. I found the information available on the Generac website helpful in determining what type and size generator to purchase. Should I need service there are many authorized service representatives in my area. This too has been a discriminator in choosing Generac over some of the other brands. Assembly instructions were clear and the quick start instructions are an excellent idea. It took no time at all to assemble and start the generator. I choose to buy a portable rather than stand-by so that I can have power to do remote construction projects. I'm happy with my choice so far. I'll follow up later after I've had an opportunity to exercise the unit.

I have used a Generac generator ( XL4500 ) for over 20 years and have been very happy. I purchased your new 6500 and will use the old generator as backup. Your 6500 starts easily, works well, and handles my power loads very well. The generator uses a bit more fuel than I thought it should. An idle mode when not in heavy use would be helpful to conserve fuel. Also, I have had many problems with the CO sensor tripping off, even when the generator was fully outside. With swirling winds it has shut down for CO sense too many times. Installing a bypass switch for the CO sensor, with appropriate instructions verifying that you are not protected from CO, would be helpful for places where people need to run the generator close to a building or under a roof away from rain/snow. It can be an easy redesign. I will use my generator in bypass mode successfully for a long time.

This is for the GP7500E. I can't do an operation review because I just finished setting the unit up and have not used it yet. It was purchased as a backup electrical source for our home. Setup was easier than reviews led me to believe, specifically putting oil in it. You do need a funnel to add oil, and I did use a funnel and hose that I already have, but a funnel with a long neck would work fine. The first unit I brought home was replaced by Tractor Supply after purchase because the spark plug boot was broken. TS was going to replace the unit with another unit in stock but the other unit also had a broken boot. They replaced it with a unit from a different store. Might be a coincidence. I opened the box and checked the boot before I brought this one home. I'm sixty years young but didn't have a problem putting it together, although it is heavy. The only piece missing was one of the little bolts that hold the battery terminals on. The unit looks good, though. I have intentions to fire that puppy up and put a load on it to make sure it puts power out. I don't know if I'll be allowed to do a second review after using it, but that's the plan.

I have been waiting for someone to come out with a generator large enough to have “whole house” capabilities in a portable configuration. I am a self-employed semi-retired electrician and have installed a number of generators, but this one is by far the biggest and best. I bought this one for my own house, replacing a 12,500/9,500 generator that was not quite big enough to run my entire house, especially in the summer with AC. This generator, with 26,500 starting watts and 17,500 continuous duty watts, will run most any normal size house. The only drawback with this is the physical size and weight. It really is too heavy for even 2 people to lift. The saving grace is it’s perfectly weight centered lift ring. I picked it up with a tractor and put it in the back of my truck just to fill the very large gas tank the first time. This really is a 5 star product from a well known and quality manufacturer of generators.

The generator was ready to gas up and start up when I picked it up at the dealer. It started immediately on the very first try and ran like a top. We installed the transfer switch and tested the generator with the same load I would expect during a power outage. It performed flawlessly! I have a good comfort feeling knowing we will be comfortable during our next outage.

It's kinda scary purchasing something you hope you never have to use, but for this generator ... that's the case! I expect good results sometime in the future; and I base my expectation on the homework I did on Generac Products. I think the best way to assure its reliability if I do not use it for 5-10 years, may be to simply store it as purchased ... but I have decided to run it 30 minutes every month instead. I'd like very much to give you all another review every 5 years !!

A third storm power loss this year and my old generator simply gave up. I am very pleased with the purchase of the Generac. It has the power to run several circuits that my house is wired to be run by a backup generator. It powers my well pump, refrig, freezer, hot water tank, and several light circuits. Its economical to run and easy to start with the battery back pack. My only con, is the oil fill is a little tight to fit a quart bottle.

This is a great generator for our entire house. No shortage of power and seems to be built solid. I really like the fact that it came with a battery charger to ensure its always ready to go. It's a little loud but not outrageous. Great generator dollar for dollar. We are ready for another ice storm with this Generac.

OK LET ME START OUT WITH MY DISCLAIMER, I JUST GOT THIS AND RAN IT FOR A LITTLE WHILE AFTER SETTING IT UP SO I CANT SAY MUCH ON THE LONG HAUL. FIRST IF YOU BUY THIS BEAST, DRIVE DOWN TO HARBOR FREIGHT AND PICK UP A CHEAP SHOP CRANE, I PAID $129 FOR MINE. THE UNIT HAS A LIFTING EYE ON TOP AND WITH THE SHOP CRANE I CAN EASILY PUT IT IN MY TRUCK OR ON A TRAILER. AND I ALSO LET IT HANG WHILE I INSTALLED THE WHEEL KIT AND FOOT. THIS THING IS PUT TOGETHER NICELY AND ALSO COMES WITH THE MAINTENANCE KIT FOR YOUR NEXT AIRFILTER AND OILFILTER CHANGE AND THE INITIAL OIL IS INCLUDED ALONG WITH CHARGING CABLES FOR THE BATTERY. I BOUGHT THIS AS A BACK UP FOR MY HOME HOWEVER IF ANY FRIENDS OR RELATIVES NEED IT AFTER MY POWER IS BACK ON IT WILL BE OFF TO THERE HOUSE. MY HOME HAS A WELL PUMP, ELECTRIC RANGE, HOT WATER, SEWAGE EJECTION PUMP, ETC, ITS ALL ELECTRIC, SO IF THE POWER GOES OUT WE HAVE NOTHING.
