Ease of setup and operation

After delivery, the Generac 7000 was easy to prepare for operation, easy to start ( electric start). Our house has transfer switches ( 6) and with our electrician we tested the system and the 7000 to make sure all was running in order. Everything was perfect the first time. I recommend having an electrician go over everything, especially with the built-in transfer switches. The peace of mind living here in Maine, that we can have heat, refrigeration, lights and some comforts is reassuring, especially if the power goes out. This will probably lead to the purchase and installation of a stand-by unit down the road. Thanks for building a safe, easy-to-operate, sensible power source in case of outages which can happen especially here in Maine. I like my comfort and this is real, real PEACE OF MIND.

Lots of power

Bought the 6500 in 2015 after losing power for 5 days after a storm. I went with Generac because of the trusted name and reviews. Recently lost power in a winter storm for two days. This baby ran for 48 hours straight through a transfer switch and powered my heat, two refrigerators, three tv's, all my lights no problem! Best $800.00 i ever spent.

99% Happy

This generator was easy to assemble and fired-up immediately. Quieter than I expected based on neighbors' units and some of the chatter online. Easy to move the generator around. The 1% unhappiness is based on the difficulty to add the oil. The generator is designed to receive oil at an almost 90-degree angle, so you need to spend a crazy amount of time carefully adding little amounts at a time or go buy a funnel with a flexible line. Also, the oil supplied does not indicate the type/weight of the oil and neither does the generator's manual. You can find it online at generac.com FAQ section. It's easy to see why it's an FAQ.

Great Home Generator. Manual leaves a few things out.

Although we've only had the generator for a couple weeks it's already proved its worth. Sturdily built this champ can take it. We opted for a portable instead of a whole house so we could take it to our homestead in MO. Took me awhile to get power running because it wasn't clear the 240 circuit breaker was the breaker for the entire electrical panel not just the 240 breaker. *facepalm* I wanted to get a maintenance kit but couldn't find the one I needed for my particular model. Anyone know?

Ran for 4 days straight

This seems to be a good generator is provided backup power for me for 4 days straight. The only thing I wish the generator had was a percentage used of power as other generators offer that feature. The only feature offered on this is the hour meter which is very good for maintenance

Love the generator!!

I purchased my GP6500 primarily to run power tools. I have a large lot which makes it impractical to use an extension cord. I opened the box and followed the instructions on assembly which was easy (putting oil in the machine, wheels on etc.). I put gas in it and it started flawlessly. I have run a 15 amp table saw and shop vac simultaneously with no problem. In addition, I plugged in a power washer and ran it for hours without an incident. When you start it and hear it run you can tell it is a quality machine. It has a lot of power and runs very smooth. I even use it when I have access to power because I like it so much.

Great buy

With all of the weather associated power outages occurring these past years, I decided it was time to purchase a portable generator as a back-up . After looking at what was available, I chose the Generac because of its reputation as a reliable machine and at a price I could afford. Love my purchase and I'm not having any worries about its capabilities and performance. I'm now in ready-mode !! / Bonne achat pour me sécurisé en cas de panne d'électricité !!

A workhorse

I bought THIS generator because of the past experience with the brand, AND because this unit had a larger engine than most of the similarly sized generators. The typical 15kw genset has an 18 to 22 horsepower engine. This model has a 30hp engine!! That extra horsepower means greater power margin for starting loads like HVAC compressors. I calculated that I needed 10kw, and this units 22kw starting capacity exceeded that substantially... But in my experience I need more than the minimum because if the hvac computer crashes because of voltage drop, then starting will fail. You mush have excess power during the starting of the compressor to keep the computers happy. So I picked carefully, and while this one has much more power than I require, the price point and performance thresholds were met by *only* this generator. So I did my first test running the whole house, and this generator handled the load with few problems, but the power was very noisy, very high harmonic distortion. Some things in the house ran fine, but things powered on transformers did not like the power. The home thermostat was inoperable, the computer in the dishwasher crashed, several of the UPS systems did not like the power and complained, and my smart LED lights were very unhappy. Sensitive loads did not like this generator at all... But once I got the thermostat bypassed, the HVAC compressor seemed to run fairly well, though the compressor was noisier than normal. So to meet my needs I decided to buy the largest inverter generator that I could fine to run the house and electronics, and the Generac GP15000E is dedicated to the HVAC compressor *only*. The HVAC blower and electronics run on the inverter generator where they are fed a true sine wave. I didn't set out to buy this much excess capacity, but I still paid less than I would have if I had bought a similarly sized whole home generator, and I have a reconfigurable power plant now so I can handle any need.

It is Loud but Works Well

Like others, I do find this generator to be a little on the loud side. I also have an older Generac 4000XL that is nowhere near as loud. With that said, I am very happy with the generator so far. I have run it only about 20 minutes but fully intend to give it a break-in workout this weekend. First impressions are it is substantially more than the 4000XL in ways far beyond just the wattage ratings. I like the electric start, the tank filler screen, the fuel line filter, the metal fuel shutoff valve, and many other details that just make me feel this generator is considerably more solid. I do wish it was a pressurized oil system and filter on the engine, but I could not justify the price increase to get that feature. All in all, I find this generator to be an excellent value. Yes there are trade-offs, but it will serve my home backup purposes well.

A really fine product

Ordered my Generac GP17500E after researching on-line and talking with friends who have Generac generators. To my surprise, it was ready for delivery in 1 day. Uncrated and assembled it in about 2 hours (instructions were good but could be more user friendly) and was impressed with the quality of construction. The supplied oil, spare filter, spark plug, etc., were added value. Very pleased with this generator and have recommended Generac to family and friends.
