Battery charger

I have had this unit for three years now and fortunately have not needed it......yet. I do maintain it regularly and it seems to run well One question......is there a specific position that the start switch should be in when the generator is stored and the battery is charging (supposedly)..? The push start will not work any time that I try to start it....I always have to resort to the pull start. This will be hard for my wife if I am at work when we lose power.....one of the reasons I chose this unit. I store it with the battery charger plugged in as recommended but the battery never has enough to start the unit. Any help would be appreciated.

Outstanding Generator

I'm a generator mechanic by trade (military) and I know quality when I see it. I am very impressed with the attention to detail. From the oil drain line to the control panel battery charger to the extra large fuel tank. Every aspect of this generator is excellent, to include all the parts needed to perform the first scheduled oil change and maintenance. In that kit was also a funnel, towel, spark plugs, oil, oil filter, air filter, foam pre-filter, etc. The frame is extra heavy duty and looks as though it would take the worst of abuse. Some other noted features: spin-on oil filter, idle control switch, fuse protected control panel, a wide variety of fuse protected power outlets, extra large muffler, electric start, never-flat tires, and an incorporated lifting eye. The instructions were easy to read and initial setup took only 20 mins or so. After hooking up the battery (came 100% charged) and filling with oil, one short push of the start switch and it was up and running. Smooth idle and steady clean power top it all off. This is an outstanding generator and I can tell that people (engineers, designers, etc) put a lot of thought into its design. I definitely recommend this generator to anyone looking for reliable backup power and/or portable power.

Nice Generator

This is a great generator as long as you keep the battery fully charged. 1. Keep the generator battery charged. It will not pull start with a dead battery. Use the battery charged that comes with the generator. 2. If you can't keep the generator on the charger install a battery disconnect between the battery cable and the battery. My battery would drain when sitting for 2 weeks or more. The switch solves the problem. I really like the generator..

Easy assembly & powered up quickly

This generator weighs over 200# but with the wheels on, it is easy to move around. Assembly was easy and I had it running in no time. Took my time, made sure all connections were secure and it fired right up. Pluged in a light and it worked just fine. Haven't had to use for emergency power yet, but now I am ready.

This product has great features

So far I only have had it for a week. It is smaller and lighter when moving it around compared to my old generator. I am slowly checking out all of the cool features it has. I especially like the ability to charge the battery just by plugging it in. and the light that will show when the battery is low. Larry

Hurricane Power source

During the recent power outage caused by Hurricane Sandy we used our GP7500E to power our entire home through a transfer switch. Refridgerators ( 2) , sump pump, Fan for gas heat, lighting, bathrooms , TV, kitchen appliances all working no problem. Unit ran 12-15 hours a day for 7 days. Changed oil at 32 hours then every 50 hours after that. Great unit. Purchased unit during the summer and this was the first big tryout. It passed with flying colors.

Easy to use, reasonably priced, Gets the job done nicely!

I already had to use my generator, because the local substation near us was shut down for about eight hours. had it up and running in about 15 minutes and ran 80-90% of the house without interuptions. Very pleased with this generator! I would highly recommend this generator!

You absolutely need this!

[This review was collected as part of a promotion.] Y'all!! This generator is huge! Built to last and so quiet to use! Being able to use 3 fuels makes it accessible! Was so easy to assemble and easy to maneuver with its handles and wheels! It powers our big farm house with ease! Definitely going to be a big help during power outages or whenever we need added/extra power!

Great product

Purchased for 2800 sq for single family home in south Florida. Fortunately the only time we’ve used it is to start it up every month to ensure everything is running properly. During the test start up’s everything is working properly and running all electrical necessary. Would highly recommend

Great Generator!!

I purchased this generator after doing some research and felt this to be the best generator by far for quality, features and price. I had used a John Deere that I paid almost 1500.00 dollars for after we were hit by a severe ice storm in 2003. The John Deere was junk compared to this Generac. The John Deere will not stay running if left in the rain or if snow blows in on it. Also the quality of the John Deere was cheap!! It had a plastic gas tank, no electric start or anything to keep it off the ground. The Generac comes with the electric start (which is great), wheel kit, a solid frame and a handle to move the generator around with. Shop around and compare you will end up buying the Generac!!
