Rated 5 out of 5 by from Generac 17500 is great but owner’s manual poorly written The good: Powerful generator provides enough amperage for entire 2300 sq ft house including a/c and 2 electric waters heaters. The bad: Owner’s manual - parts list, item descriptions and assembly descriptions do not match what comes out of the parts bag. C’mon Generac - you can do better! Overall: I am pleased with the generator. It is a fine piece of engineering. I also like the relocation of the 50amp outlet from underneath back up onto the front panel where it was on my old 15kw - nicely done!

Rated 4 out of 5 by from Great Features and Value, but lacking in Documentation I really think you did a good job designing this product. The Maintenance will be quite easy based on how it;s designed. I really like that the Oil Filter, & Air Filters are VERY EASY to access. Changing Oil with the attached discharge hose will be Easy & Clean. That being said, I really don't understand what you provide such useless Documentation. The assembly details are so Tiny I had to use a Mangnifier to be able to see them. Additionally the Hardware defined in many locations was not the Hardware required. It's really no n=more expensive to provide GOOD Documentation than it is to provide Poor Documentation. Additionally, I was missing Hardware, and had other Hardware that was not used. The instructions are Vague & unclear for anyone who has not assembled oner of these already. That part really needs to be rewriten!

Rated 3 out of 5 by from A few disappointments with the 17500W generator purchase I have not started the generator yet but in getting it ready I've identified a few disappointing aspects. First and probably the biggest disappointment is the requirement to measure valve clearance at every 50 hour interval. The owners manual informs you this is pretty complicated (without describing the procedure) and suggests you have a qualified dealer do it (...did I mention the requirement for every 50 hours of operation?). The generator came with a note indicating the unit is "shipped without oil" and they supply 2 quarts for the required 1.7 quart capacity. When I poured the first quart in, the oil level was well above full on the dipstick ….indicating the engine was not even close to empty of oil. I also found the assembly instructions to be near non-existent because the exploded view of the assembly was so small in the users manual; also - it did not reference torques for any bolts or wear lock washers vs. nylon nuts should be used. I also noted two wires stretched very tight across the oil filter - which needed to be disconnected and re-connected following a less stressful path. I truly hope the generator will work well despite these initial findings.

Rated 5 out of 5 by from This Generator meets all my expectations. With the exception of one part missing in the shipment, the generator went together easily. The instructions were clear and well written. The missing part was sent quickly with no hassles. It runs my home with no problems.

Rated 5 out of 5 by from excellent product I purchased the GP17500E to replace a Generac 15KW/22.5KW generator that I purchased new over 15 years ago. It is noticeably quieter than my old unit ( which still functions perfectly and is now my emergency backup ). Being that we live in S. Florida, having a reliable generator is extremely important. I had numerous brand options, but chose to go with a brand that has served me flawlessly for over 15 years through many hurricane related extended power outages. When you really NEED a generator to work; you will be glad you purchased a quality brand like Generac. I now own 4 Generac units. Two GP3600's for running several small window AC units 24/7 and my big GP17500 and my older 15KW model. Due to limitations on fuel storage, we only run the big unit 4-5 hours a day.. the little units will keep us at a comfortable temperature all day and night powering the window AC units using much less fuel.

Rated 5 out of 5 by from Piece of mind I opted to buy a portable home back up generator opposed to a built in because of the versatility. It will do the job of a built in but I have the option to use it for other things as well as loaning to someone else if I haven’t lost power in the event of a hurricane or other natural disasters. Upon delivery I was impressed with the ease of set up and overall performance of the generator. I expected it to be very loud but was actually surprised that it was not unbearable. Overall very happy with the purchase and not as anxious with the upcoming hurricane season starting.

Rated 5 out of 5 by from The GP 17500 is a GREAT UNIT Decided to go with this unit instead if a whole house generator.This unit will supply the power we want plus it's portable. A lot cheaper that installing a whole house generator.
