Great for whole house use after tornado

I just survived a devastating tornado in Chattanooga in April 2020. I actually bought this generator in 2013 for emergencies but had not used it much until now. When my areas grid was completely wiped out I rolled out the GP1500 and ran it for over 3 days to keep my house running and food frozen, Many of my neighbors lost all their food and with the Covid crisis going on that is a serious time as we are on lockdown here in Tennessee. The GP1500 powered my house and kept my family safe and fed and warm etc until power was restored. What a great product and it never flinched with the hot water heater, or HVAC etc running. All I had to do was be careful and not try to run everything all at once. Thanks Generac you saved us in 2020.

Should do what it is designed to do

It was a gift from a son-in-law. I have started it but have not used it as we are still trying to get our house wired for it. One complaint was that the manual with it was not very good so I had to down load one from the web site. Also it arrived without the axle but when I called Generac they shipped one right away.Since it is so heavy I had to get help in installing the wheels and axle. The Generac people(Power Solutions ) in Jasper, GA did send a man over and he did the work for me and made all the proper assembly needed and was very friendly. This generator is to be used in case of power outages that we have often..

Great Generator

This is a great unit. I live in a colder climate in a home with base board electric heat. The unit handles the house load well. I had no problem with the 2 ton heat pump/air conditioner. Assembly was easy enough, but instructions on wheel assembly could be improved with larger diagram. This unit is heavy. The pneumatic tires are good. the only negative is the wheels should be bearings instead of bushings. This could make the unit a little easier to move around. Unit is a little loud, but that can be expected with a 30HP engine. A second muffler attachment could help if it didn't place to much back pressure on the engine.

Great Portable Generator

We lost power due to a storm and it was going to be at least of couple of days before it came back. I bought this one in a pinch but hindsight I'm really glad I did. Very easy to operate and starting was a snap. I was easily able to run my two refrigerators and three freezers, with room for more. I'll get this tied into the house and be able to run my well and furnace as well. Great product!

Good machine but no load monitor

Assembly was rather easy, unit started right up with the electrical start. Was disappointed that the unit does not have a load monitor that tells you how much of output is being used. This should be an important addition to the unit. The breaker switch technique just tells you when you have over loaded the unit.

Great Features

Good value for the money. Will take stress away from power outages. Protect my home from water freezing in pipes and damages thereafter during winter months. Comfort for family during outages. Can't rely on Power Company to get power back in reasonable timeframe, less than one day. Have had outages lasting 1 - 3 days. Power Company continues to get worse every year due to their lack of maintenance, outage prevention, manpower reduction.

Only generator I considered buying.

Great product, well made, starts immediately with electric start. I only ran it for a short time after installing the house electrical transfer panel. Generator handled everything with no problem. I do wish that there would be an oil filter for the engine. I know someone with a 10,000 watt generator and that has an oil filter.

Excellent generator. First time owner, couldn’t have been easier!

[This review was collected as part of a promotion.] I haven’t used a modern generator before - last one we had was 25 years old, was noisy, shaky, and we’d wear ourselves out getting it to start. Oh, and then there was the exhaust, smoke and low current. Not anymore! This thing is a dream. Arrived well packaged and was a breeze to set up. Basically you attach the wheels, front rests and handle and it’s ready to go. Well you add oil (included, along with a handy funnel) From there, startup instructions are well documented in the book AND on the generator itself. I really appreciate that there are easy to follow graphical steps on the unit itself for starting and running the unit. A few quick pulls and it was purring like a kitten. I haven’t had a chance to put too much load on it, but so far it’s easily powered everything I’ve thrown at it! The unit is heavy, feels like everything is high quality, and I expect it to last a long time. Definitely recommend!

NOT USED YET

GOT MY GENERATOR, HAD NOT BEEN FOR HAVING A CHAIN HOIST , DOUBT THAT I WOULD HAVE BEEN ABLE TO PUT WHEELS AND FOOT ASSEMBLY ON. SOME PARTS WERE MISSING SUCH AS WASHERS, NOT A BIG THING, ONE SPACER FOR THE WHEELS HAD TOO BE GRIND DOWN TO FIT. THIS SHOULD NOT HAVE BEEN? ALL OTHERS THING WORKED , START UP ETC. HAVE NOT YET A CHANCE TO PUT IT TOO THE TEST UNTIL NEXT POWER OUTAGE. SO PERFORMANCE CANNOT BE COMMENTED ON. GENERATOR QUITE HEAVY BUT WAS ABLE TO PUSH AROUND IN SPITE OF MY AGE OF 65. UP HILL GRADES A DIFFERENT STORY.

This unit has everything I need to keep the essentials of my home running during an outage!!!

This has been a great unit right out of the box. Easy to assemble, simple easy to read starting and usage instructions, portable and enough power to maintain my home in a safe and functional state during a power outage. Easy electric start for my wife if I am away on business. Great generator, bought 2 more for my children's homes.
