Rated 5 out of 5 by from Reliable I purchased this Generac generator about 6 months ago and have had great experiences with it so far. I purchased the unit from Home Depot but had a Generac dealer in my area install it for me. This unit can back up my entire house with the 200amp transfer switch I purchased with it. I also had to purchase the battery and made sure to get the engine warming kit. I run it off my current natural gas line so I dont ever have to worry about running out of fuel. This unit tests itself automatically once a week so you know it will work when there is an actual outage. Great peace of mind!

RE: Installation

If I purchase this unit will Home Depot Install it with the AT Switch? i.e. Generac 20Kw system???
Asked by: Anonymous
Currently Home Depot does not have an installation program for Generac standby generators. Instead you can simply purchase the unit from Home Depot online or in a store and visit Generac.com and use our "Find a Dealer" link at the bottom left of the screen to find a dealer closest to you who can install it.

how much propane would the 20 kw generator use in 24 hrs off operation and can it be set on a timer so it only runs on weekend when were at the cottag

Asked by: Anonymous
At full load on propane this unit will consume 106 cubic ft/hr or 2.90 gallons/hr or 10.98 litres/hr. At half load it would be 69 (1.89) [7.15]. It cannot run on a time; it can only be set to "auto" where it kicks on right when utility power isn't present, "manual" where you manully start the unit whenever you please, or "off" when you don't want it to run at all.

What is included with your generac generator 20 kw?

Is the transfer switch included with this unit? if not what is the cost? does the unit come with a batterie? If not what is the cost? does the unit include winter package? if not what is the cost
Asked by: nine137
This 20kw comes with: composite mounting pad with base fascia, a 1 foot flexible fuel line connector, and a 3 year warranty. The transfer switch, battery, and winter (cold weather packagae) are not included. The battery is available online (model # 5819, just type this in the search box on HomeDepot.ca and it will find the product for you). The cold weather package is model 5948 and the type of transfer switch depends on what you need. Does your home's service have a 100amp or 200amp service? Does your switch need service disconnect or not? If you need help making a selection for your transfer switch please feel free to call us at 1-888-Generac.

will this unit run the entire house, 200 amp entrance

Asked by: Anonymous
It's tough to answer that question without knowing how big your home is and what appliances are in it. Go to Generac.com and click on "Residential Generators" and then click the "Select the right generator for you" link to help give you a rough estimate on what size your home might need.
