Sucks

I bought one of these generators for a backup for my Ryobi generator and it’s so frustrating!!!!!! It takes forever to get the thing started vs my 10+ year old Ryobi to start. I can start my old Ryobi with 3-5 pulls and it has well over 100 hours on it as it’s over 10 years old! But my generac is much harder to get started and it’s got maybe 10 hours of use on it! I wish I had bought 2 of the Ryobi generators at the same time!!! You say you’re one of the best out there but even Coleman is easier to get started than generacs! I would give it a lower rating but once you finally get it running it does its job. I don’t think I will ever buy another one again unless it’s the cheapest option in a pinch. Good job generic!!

Does exactly what is advertises.

I purchased the gp3000i to use with my rv. It starts and runs the a/c with no issues with the standard battery charger working and the fridge running on electric. It fires right up with gentle pulls and is easy on fuel considering the output. Did I mention that it is quiet, so quiet that at full load you can stand right over it and have a conversation, without yelling. Nice package and light enough to move easily, well done. I'd buy it again, wouldn't hesitate at all.

Quiet unit

Bought two inverters first one display did not work returned to stored for exchange unit. First trip out after two hours of running shut off for the night and went to start in the morning to find no output from electrical. Hope this isn't a sign of what is to come with these units warranty fixed waiting to try again. I've owned Generac generators before and loved them this is my first inverter.I did a lot of research and found for the money this was a good deal

Out of the box

Fresh out of the box it was great. I am a senior woman yet I could lift it, understand the operation, and start it. It is perfect for my camper. I will probably go ahead & get another one along with the kit to do parallel operation. It is quiet, efficient and obviously well made. I am happy, happy, happy with everything about it.

Lasted 10 hours

Was thrilled to get this unit and did a ton of research before purchasing. I ran this unit for approximately 10 hours and the digital screen stopped working. This was under a minimal load and under normal weather. After I shut it down for the day there was fuel leaking out of the case and onto the ground. I haven't been able to identify the leak but I suspect its likely carburetor related. I am currently working on locating a service repair dealer which is much harder than I thought it would be. The only dealer I have found listed on the Generac website who actually does repairs is 16 weeks out. I might have got a lemon of a unit but regardless its frustrating that there is no great repair options.

Love It !!!

I purchased this portable generator for use around my farm and as a power source when camping. I was pleasantly surprised at how quite it operates and the Fuel Gauge, Time to Run and Power Usage read-outs are wonderful. I removed from the box, put in oil and pulled rope twice to make that initial start. A big plus is my wife likes it too. Great Product, Excellent Reputation, Top Notch Quality

Broke down after 3 hours

Bought this generator for California’s wild fire power outages, after 3 hours of runtime the generator started running rough and not producing power. Contacted Generac to fix it under warranty, Generac referred me to a local repair shop, I’ve been waiting for 6 weeks now to find out what’s wrong with it. I have a $1000 generator that has spent half it’s life in a repair shop without any answers.

Brand new out of the box and to the shop!

We ordered this Generac generator because of the positive reviews but sadly are disappointed. We had to order two and neither one of them worked as they should. The first one the exhaust blew white smoke and a strong odor of fuel/oil. We followed the instructions in the owners manual. We ran it several times hoping it would go away. It was suggested by Generac customer service to send it back. We ordered a second one with high hopes that this one would be good. However, after prepping it as recommended in the owners manual, the green ready light did not come on. We plugged lesser expensive equipment in to the unit and it worked. However, if the ready light isn't working properly, how do we know the overload and oil lights are working. This time Generac customer service suggested we take it to a certified place of service. So we have a brand new out of the box Generac generator at a service center, never been used. Very disappointing. It's been 5 weeks since we ordered the first one and we have yet to have a working generator.

Super quiet!

Bought this portable for my camper as a backup and for state parks where there isn’t any electrical hookups. Went with Generac because i also have a 17KW on my home. Excellent brand! I was surprised by how quiet this guy is. You walk 10 feet and it is like its barely audible. I recommended it to my friend who was looking for one. He bought the same model (iq 3500) and he is also thrilled! I can highly recommend this generator for performance, affordability and looks.

All gasoline generators

I recommend on using recreational Fuel in all gasoline portable equipment. And if you are going to let it sit for an extended amount of time , run a stabilizing additive In the fuel tank and start engine for about a minute or so. To be on the safe side if the unit is not going to be in service for months I would drain fuel tank then start engine to run fuel out of all lines and also drain carburetor fuel bowl.
