Good value for a high quality product

This unit has everything I need for home backup. It's a heavy machine but the pivot handle makes it easy to move around. I also like the never flat wheels. The only drawback is the lack of clear instructions for changing oil and draining fuel. The instructions are vague for a novice like me. I need more detail and better drawings. Well worth the price I paid for home backup.

Very easy to setup and use.

Everything with this product met my expectations and functions were easy to use. However the only thing I have to complain about was the products packaging was perfect but the product was damaged inside the box. The fuel line nipple was broken at the back of the control valve and was leaking fuel. The problem was the fuel line was cut too short and pulling on plastic nipple.

Solid & Effective

A portable, reliable, economical, means of standby power. It is a bit louder than I like but wear earplugs if you are bothered by the noise level. This machine is used for jobsite applications such as a vacuum,portable halogen lighting and misc. charging. Follow the wattage charts for appliance applications to ensure you have the right size generator to handle the load required. Do not overload any machine even a Generac.

Great Generator

Purchased the gp6500 after a lot of research. It offered the best power for the price. We only had to use it for a little over 1 hour for the first 7 months we owned it. We have been faithful in starting it about every other week or so and ran it with a load for about 20 minutes. We have kept the tank full of gas treated with stabilizer. Well sure enough we lost power this week do to freak March snowstorm. Started on the second pull. It ran over the course of three days for 29 hours. Worked flawlessly. Really a lifesaver, especially with three kids and the wife. Ran 3/4 of the entire house including a well pump, two refrigerators and a deep freezer. We have a Woodstove in the basement so no need for it to run a heat source. Bottom line... Awesome product, great value and so far seems durable. If you're debating this generator, go for it!!!!

happy customer

I would definitely recommend this generator to anyone who is in the market for back-up power when the need arises. We just recently bought ours, and I can say without hesitation that I wish we would have done it along time ago!! Great product, and a well made investment.

Nice and Quite

Had to replace my old generator (That was not a generac) that had for the last 15 years. Bought this from a local vendor. The unit started right up. I already have a generac home standby but It really uses the propane to run all night. I use this to just run fridge and furnace at night. The home standby was the best purchase ever. Soon as the power goes out the standby will start right up. I have the 6500 run just a few circuits when don't want the standby running. The 6500 has electric start which is nice. I was without power when 1st bought and it ran for 16 hours straight. No problems. I would recommend the generac name to anyone. After bought my home standby my inlaws bought one and love it. Highly recommend the portable 6500E.

Nice generator.

Just the right size with the right features and at the right price. Wired it in myself with a Reliance generator transfer switch. Bought a GenTent for wet weather use. Had to use it twice already and it worked out great. I'm very happy with my GP3600.

GP series Generac

Great Looking Unit! The electric start is why I chose this unit. I installed the wheels, handle, put the oil in & connected the SUPPLIED BATTERY, put the gas in, hit the start button and it started right up. No more pulling the rope for this old guy! It does have a backup pull rope by the way. The unit even comes with charger to keep the battery charged also when not in use. Didn't see that with the other ones out there. This is a great generator and I'm glad I bought this one!

Generac GP18000EFI

The generator is being used to charge batteries and run a small cottage at the same time. No complaints about weight and size as it's expected. It fired right up and started going to work. The only problem we have encountered is the 30AMP breaker keeps tripping if we run small window air conditioners (5AMP) or anything at 1,500 watts=12.5AMPs for a brief 5 min. The offgrid includes four banks of 48V AGM batteries. We set the Magnum inverter down to 80% and AMPs down to 38. This seems to be helping but we can't put a larger load on. So we installing a 50AMP plug on the house with a cut off and bipass, essentially we will be running the 30AMP plug to charge the batteries and the 50AMP to run the house. Typical charge on those batteries is around 4 hours. If you plug an appliance at 12.5 AMPs direct to the generator - there's no difference in load sound. As a building contractor we designed our own off grid system and will be writing a book with as much detail as possible.
