Generac 20 Kw
The power here has been going out at least once a mouth,sometimes for 2 to 3 day. With my old diesel portable one I would have to go out to the pole building, hook it up get it running, it was a real problem. I wanted something that would do all that, plus I have 4 cancer so if something happen to me my wife wouldn't have to all that stuff. Its a really good feeling knowing she'll have power. Thank you
Pros: Durable, Quiet, Exceeded Expectations, Reliable
Cons: Heavy, Packaging

Worked Fine!
On July 5th.. lost power 4 times, in about 18 seconds after loss, Generac kicked in and worked fine. All 4 losses of power within an hour..I do need a video telling me how to operate the Control Panel. Instructional Manual not Clear. Also Maintenance Video would help a lot !
Pros: Fast, Reliable, High Quality, I'd Buy It Again
Cons: Difficult To Use, Bad Instructions, Nee

The Surest Way To Prevent A Power Outage
After experiencing a 24 hour power outage last winter, my wife finally agreed to the purchase and installation of a whole house emergency generator system. I had been advocating for years, and had a portable 7000w standby generator that never worked when we needed it. The tipping point came with a large snowstorm that prevented travel to her office and loss of power at the same time. She had no computer access!

We have natural gas for all utilities but most(other than range) won't work... more

A Piece Of Cake
The generator was installed in November of 2009 and worked problem free from then. When the yellow light came on, I had to go to the manual to find out what the light indicated.

Ordered the maintenance kit on line and had it in my hands within 4 days. I was impressed!

The directions and illustrations were top shelf and the installation went without a problem. I will have to come up with something else to hold the old oil rather than the gallon milk bottle I tried initially. I want... more

Annual Service Parts For Generac 20kw Home Standby Generator
The dealer wanted $200 to do an annual service on our generator which is not a bad price. But, as a DIY person I was able to complete the task with the parts from Electric Generators Direct in 30 minutes and $30, with factory parts that I was unable to match from the local Walmart or Auto parts store. Worked out well.
Pros: Price, I'd Buy It Again

Good Company!
Installed the Generator about a year ago. Has been great up to about a month ago. Now I'm getting a low voltage warning and I cannot get a straight answer as to what part I may need. The service folks can't even give me a straight answer. I firmly believe they know what the fix is but want to fix several things just to run the tab up. Otherwise we love the generator. It still runs fine when the power goes out and it runs fine on the weekly test. I would recommend generators direct to everyone.... more

Problems W/initial Installation.
Opening to insert battery into the compartment was difficult due to the tight opening. Required my using a board and hammer to force it thru the opening (and yes I had the correct battery).

Also the locking mechanisms required that I file the holes where the latch goes thru needed widening. A flat file fixed it with approx 1mm being filed away.(Right side when facing generator only).

Other than that, it runs good and performs well. Fortunately, we have not had any lengthy outages. I... more

Maintenance Kit
Excellent price and delivery; I did the maintenance myself for the $20 the kit cost plus oil. All of the Dealer Prices around here for maintenance ranged from $200 to $350 to change the oil and filter. It took me 20 minutes total. Thank you Electric Generators Direct.com.

Hurricanes
I live on the coast of NC. Subject to the occasional hurricane(Irene on the way). Power is frequently out. I've been contemplating a standby generator for years and finally did it. Ordering from EGD was simple with good help. Delivery was smooth with the help of my neighbor and his fork lift.

My electrical contractor co. was well versed in the generator and had been to "Generac School". they set it up and wired in the smart switch and did a test run after the gas man connected the... more
