Q: I have 200 amp service with a heat pump and all other appliances are electric. Will I be able to have my whole house work with this model?
by Vincent Generoso from South Carolina on June 30, 2016

A: Thank you for visiting Electric Generators Direct.

In regards to your question, proper sizing of the generator is crucial to the success of any installation and requires a good working knowledge of electricity and its characteristics, as well as the varying requirements of the electrical equipment comprising the load. When analyzing the electrical load, consult the manufacturers nameplate on each major appliance or piece of equipment to determine its starting amperage.

The following formula can help determine the starting wattage. (Starting Amps x Volts = Watts) When choosing the generator output select a rating that is approximately 20 to 25% higher than the peak load (for example, if the load is about 8 kilowatts, select a 10 kW generator).

A higher rated generator will operate comfortably at approximately 80% of its full capacity and will provide a margin of flexibility if the load increases in the future.

certified electrician should be consulted for proper sizing and installation of any generator.

I have attached the Generac estimated sizing calculator to help you get started.

Electric Generators Direct Recommended

Sometimes, air cooled generators just aren't good enough.

The Generac QuietSource Protector 22kW is the ultimate "entry-level" whole house generator.

First, it features a high-quality automotive-style (instead of lawn-mower style) engine. Instead of running at 3600 rotations per minute, it runs at 1800 RPM. By running at half the speed, the engine is a lot quieter, consumes less fuel and lasts much longer.

Secondly, the QuietSource includes WhisperTest technology. When... more

Extended Warranty And Product Review
Since we just purchased and had installed our new Generac 22kw, a few weeks ago, we found out about your free 10 yr. Extended warranty program. We would like to apply for that, please send us the information.

This is our second Generac Generator. Our first gave us good and dependable service for our home in the Sierra Nevada Moutains in California. We moved to a very remote home on the shore of TableRock Lake in Southwest Missouri. Occasionally,There are power outages and we want to be... more

"Our Generac Generator was shipped on time and received in perfect condition on a wood pallet and enclosed in a large heavy cardboard crate! We had a professional electric company hook it up as it sits proudly on a large concrete pad we had built just for it! We don't wish for a power outage, but we're not afraid of one either!"

I Am Very Happy With This Generator
I am very happy with my new generator. I wanted the automotive engine and that is what made me decide on this model. I am very happy with my purchase. It is quiet and it runs everything in my house. My test run on a power failure it started and transferred flawlessly. I haven't had a major power outage yet, but I'm ready when I do. I expect no problems. I would recommend this generator.
Pros: Easy To Use, Quiet, Exceeded Expectations, High Quality
Cons: Heavy, Expensive
