Very impressed with quality of this product

I ordered the GP3000i. I had not actually seen one in person. It showed up on my door step earlier than what had been projected. I am extremely pleased with the appearance and quality of this product. Started on first attempt. I will be using for home back up and my RV. My main concern beside reliability was portability. I couldn’t be more pleased. Thx

Customer Service and Warranty issues

I bought this generator after doing my research and wanted to get one with a great warranty and a company that would stand behind their product. I got neither. Long story short had an issue with the generator after initial break in process. Oil was coming out of the top end and most places where it shouldn’t be, I have it well documented. Took it in to certified retailer to get warranty work done and Generac refused to pay for a dime. I have had issues contacting their customer service reps and so on.

GP3000i a great purchase

I initially intended to purchase the new 2500 but went with the 3000 thinking more is better and the retailer had a promotion on the 3000. I have used it almost daily with power tools since purchasing 3 weeks ago and absolutely no regrets. A friend has a Honda 2200 inverter and the GP3000 is every-bit as quiet as the Honda if not more-so. It has started on the first pull every time. It appears to be fuel efficient although I have not run it dry so I cannot speak for hours on a tank of gas. I do wish it had a fuel or hour gauge. With a full tank of gas the unit weighs around 66 lbs. which is a heft for me. The Generac literature implies the inverter unit all have the outlets protected by a dust cover - this is not true for the 3000. I do wish they would include a protective cover for the GP3000i for protecting the case and controls from dings and dust when transporting or storing. My research indicates the units are made in the USA - Wisconsin. I considered units by 4 other manufacturers and I am very comfortable with my decision to get the GP3000i.

Great Unit!

I wanted a quiet unit that would power several items while doing BBQ competitions and events. I am very happy about how quiet this unit is and it has more than enough power to run all my equipment. I was also pleased on how easy the pull start was on this unit. I would gladly recommend a GP3000i to anyone looking for an inverter generator.

Great product

I tossed around the ideal of getting a portable generator so I wouldn't have to lug around my other larger ones. I was convinced that the Honda eu2000 was the best and quietest on the market until I started reading about the Generac iq2000 and watching some videos. I just couldn't make myself spend 900.00+ for a Honda. So I purchased the Generac iq2000 last week. It arrived extremely well packaged, with manual, engine oil and funnel. Added the engine oil and some gasoline and it fired right up. This unit is quiet !!! performs well and I love the features it has. Well done Generac !!!

Part of My Readiness Plan

As a resident of earthquake country, and a member of our local Community Emergency Response Team (CERT), I needed to complete my preparedness kit by adding a home generator. Unlike other users who have reviewed this model, I am not a camper, I don't regularly need portable power for tools, nor do we have an unreliable power grid. However, I don know what will happen when we have a large earthquake and that power will be unavailable for days, perhaps even weeks, following such an event. As a CERT member, we practice for such situations all the time and I have seen plenty of portable generators in use during these exercises. I'm impressed by the cost/benefit ratio of Generac and trust that the IQ series will be just what I need for my home. I regularly run it as part of its maintenance schedule, place an electrical load on it, and am very satisfied with its performance. As I live in a townhome complex, my neighbors appreciate that it runs quietly.

Not Quite Adequate for RV AC

Despite it saying it will power a single rv ac, NOPE‼️ At least not here in Moab Utah. Keeps throwing a engine code on the control panels. Unit stays running but doesn't generate any power. And it doesn't throw the units breakers. My 30yr old Makita 3500 watt powered it just fine, but, it was much louder and thought the quieter unit would do the trick...WRONG‼️

Never worked under load

My neighbor brought this new and it never worked since new. She gave it to my and I contacted warranty department and the said to take it to a city repair shop. The shop could not get help from the company. Thankfully I didn’t get a whole house generator. I have paperwork to show lack of help from manufacturer.

It runs the RV AC and it's quiet.

The Generac GP3000i is a great little generator. I almost didn’t buy it because I couldn’t find any reviews. I’m glad I did - It’s quiet, light weight, easy to operate, and powerful enough to run the 13,500 BTU A/C unit in my Airstream. I can’t comment on reliability or durability yet, but Generac has a good reputation so, I’m not worried about that. This is the second generator I bought this summer. The first was a lower cost open frame generator (NOT a Generac) which leaked oil like crazy and was so loud the campers in Shenandoah National Park applauded when it turned off. In looking for a replacement, I really wanted something quiet and powerful enough to run our RV A/C. So far the Generac meets all my expectations. Light weight ~ 59lbs. It’s pretty similar to lifting a dumbbell. It can be done with one hand. Super Quiet – is an accurate description. At 20 feet it’s slightly louder than ambient noise. Power – it barely surges when starting the Airstream A/C (2-3 second surge) and then normalized almost instantly. It had no trouble running the A/C and everything else in the trailer concurrently (running the microwave at the same time as the A/C is too much). Easy to start – typically starts in one easy pull. My only complaint (and this is small) is that I had to buy a RV 30 amp adapter to connect to the Twistlock Outlet. It was ~ $12.

Began positive

I have had several carb issues. I worked where we sold Generac generators, and always spoke highly of them. I owned a GP5500 prior w/ few problems. I always kept ethanol free gas or gas w/ Stabil in my IQ3500 . Which purchased 9/2019. I had one carb replacement a year ago ,after a month wait for parts from Generac. It would start but not run and the ECO setting would shutter and shut the engine off. Now it is repeating problems, after only being run on ethanol gas for less than 1 hour. We used it to run the 13.5K A/C or to run heater fan and charge RV batteries. We were able to do one or the other at a time. It was never able to pull the 25 Amp specs.
