Outstanding Generator

I'm a generator mechanic by trade (military) and I know quality when I see it. I am very impressed with the attention to detail. From the oil drain line to the control panel battery charger to the extra large fuel tank. Every aspect of this generator is excellent, to include all the parts needed to perform the first scheduled oil change and maintenance. In that kit was also a funnel, towel, spark plugs, oil, oil filter, air filter, foam pre-filter, etc. The frame is extra heavy duty and looks as though it would take the worst of abuse. Some other noted features: spin-on oil filter, idle control switch, fuse protected control panel, a wide variety of fuse protected power outlets, extra large muffler, electric start, never-flat tires, and an incorporated lifting eye. The instructions were easy to read and initial setup took only 20 mins or so. After hooking up the battery (came 100% charged) and filling with oil, one short push of the start switch and it was up and running. Smooth idle and steady clean power top it all off. This is an outstanding generator and I can tell that people (engineers, designers, etc) put a lot of thought into its design. I definitely recommend this generator to anyone looking for reliable backup power and/or portable power.

This product runs great and has great safety features

Recently we went through a 90 hours power outage and this generator combined with the Generlink transfer switch got us though this outage with minimal inconvenience. Only had to use this generator a few times since i purchased it two year ago but it has been a life saver

This generator was a God send

My house caught fire and was unlivable. But we had 2 freezers with LOTS of food in them. I bought this model generator, at a reasonable price, to keep my freezers running until I could get my house livable again. It’s the perfect size and wattage for me, affordable and it runs for ever on a tank of gas. Thank you Generac!!

Portable replacement for a standby

No major loads put on it yet, but so far so good on this generator. Starts easy, not too loud. Nice that it came with a start up kit, wheels, and a handle which seems to be extras on other brands. Idle control when running with no load would be nice, but it wasn't a deal killer. I like the steel fuel tank and the quality of the fuel shot off valve. Went with the portable unit with manual transfer switch when the old standby failed. Will be nice to have it in the garage, out the elements, ready to go when when needed.

The Little Generator that Could

During Hurricane Sandy we were without Power for 13 days. My friend got power back in five days so he lent me his Generac GP 6500 and it powered my four bedroom house for 8 days without a problem running about 20 hours a day. So I went out and bought one for myself. My neighbors with bigger generators were very impressed with my little generator that could.

Worth every dollar invested!

After losing power for 9 days during Sandy, and just missing the bullet during the winter of 2014, we decided to quickly purchase this generator to avoid future problems. Based on earlier research I looked for a Generac and found one by luck at a local dealer. The generator is VERY easy to start and use, and powers almost our entire home - no need or a full house unit! Excellent price - including transfer box installed about $2000 total - well worth it for peace of mind!

At least the rope start is easy, the battery didn't last 3 months.

The GP8000E is a very capable machine. It can run our whole house and never falter. The electric start was a requirement so my wife could crank it up. There is the first weak spot. The machine is just 4 months old and has 3.2 hours on it and the start battery has cracked and is leaking. Yes, I recommend the unit, but I recommend that you plan to replace the starting battery very early. The 20amp cord that comes with some is of marginal utility, I suggest that you look a 14-30 cord if you chose to do much at all.

User friendly

We purchased it on the morning of the day that Irene was to hit. Set up was easy. We lost power the next day for about 8 -9 hours. Easy start. Hooked it up to sump pump immediately. Eventually hooked up our fridge. Plenty of voltage left over if we wanted to hook up more. It is ready to go if we have power outages during this winter.

Not impressed with Generac equipment and parts

Bought GP8000E in Feb 2025. Only had to use 4 times, had no problems until now June 20, 2025. Now one of the GFCI output units keeps tripping after 7 seconds with nothing plugged into it. The reset button keeps popping out. Tried pushing the reset button also. The GFCI is bad, this problem should not be happening after only 4 uses. The unit is only 5 months old. Generac reports they have none of these GFCI units in stock and do not know when they will be available to ship. Generac service dealer tells me I need to leave the unit with them and possibly in 2 to 6 weeks they may get an new GFCI unit. UNBELIEVABLE !!!

????

I used my generator once up to this point. It powered my house for a day. It’s a duel fuel generator, I wanted to use the propane option, read and reread the manual numerous times, but could not get it to work. I used gas. In order to get it looked at I’d have to lift the generator into my suv, which is impossible. I feel it’s ridiculous that I can’t get someone to my house to look at it, get it working properly.
