Customer Questions & Answers

Does this come with an exercise clock so it turns itself on and off automatically?

It turns on (maintenance cycle) weekly for 20 minutes. Once you set the time, it will do this automatically every week at the same time.

Will this unit cover a 2,300 sq. ft. home?

Asked by: Anonymous
Hi Lane, Thank you for your question. According to the manufacturer This generator will cover a typical 2300 sq. ft. home with mostly gas appliances. However the deciding factor is the number of electrical appliances in the home. With the GE symphony II system you can manage those appliances to make sure you never overload your generator and still have access to everything in your home. The unit will have one module in the package. Hope this helps!

Does the unit come with a propane or natural gas tank?

Asked by: Anonymous
Hi Semfan, Thank you for your question. The generator does not come with any fuel tanks. The Standby generators are typically installed with the homes already present fuel source. This generator can be run on Natural Gas or Propane. Hope this helps.

How long can this generater run during an extended power outage, where you are out of power for several days or over a week?

Asked by: Anonymous
Hi PRJCHOAAY, Thank you for your question. Yes, the generator can run for days without stopping. And the manufacturer however recommends oil changes every 100 hours to maintain peak performance. Once that is completed the unit is ready for another 100 hours of run time. Hope this helps!

Customer Reviews

20,000-Watt Home Standby Generator-DISCONTINUED is rated 4.7 out of 5 by 3.
Rated 5 out of 5 by from GREAT UNIT! My wife and I purchased this unit for our home in the mountains in San Bernardino, CA. We have had the unit since January, 2011. I have MS and I am disabled, we have chair lifts in our home and God forbid I need to be on a ventilator it would save me. The unit self test for 20 minutes every Saturday. It is quiet and really is white noise. We have had several power outages in the past year the longest lasting 5 hours in the middle of February in a huge, cold, snow storm. The generator kicked on right away and ran our whole house with no problems. It runs on natural gas so with natural gas you only get 18000 W but more then enough to run everything in our house and then sum. If you have the means and the need I highly recommend this unit!!
