This 20KW is a great whole house generator. It is tied in my main panel, and powers everything. I have the wireless monitor in my kitchen to keep an eye on the Heartbeat of the unit. The only thing I would change would be to exchange the trickle charger that comes with generator with a better quality, like a Battery Tender brand. LMartin from Kuttawa,KY

I have had our 20kw Generac Aluminum generator for over 5 years and she has never missed a beat. Compared to an older 15kw steel jacketed generator we had at our last home this unit stll looks like new. It has the automatic transfer switch which also has never failed us. We live in the heart of Hurricane country but I trust that my Generac will be at the ready when the time calls. Maintenance and oil changes are a snap and I could not be happier. I am thinking of installing one at a home in Colorado which also has many power outages.

Coastal Living is better with a backup power source during times of severe weather. My automatic 20KW propane-fueled Generac provides the power to run my entire home. The system self-tests once a week and hearing the generator start and run automatically is reassuring to this coastal homeowner. Working with my local electrician, Aaron's Electric, the installation and testing of the unit went smoothly. The unit was shown to provide the power to run all the appliances in my home. The power changeover to generator power takes about 10 - 15 seconds once the unit is running and outages are less than 1 minute during the transition. I am very happy with quality of the unit and the ability to keep my household running during times of severe weather. Generac power systems work well and provide the backup needed during power outages. I recommend this product for all coastal home owners.

This 20Kw Guardian powers one half of my home: 2 bedrooms, den, kitchen, breakfast area, laundry room, garage, covered porch. This include: heat pump, 2 refrigerators, freezer, washer, dryer, stove top, oven, microwave, Rinnai water heater, 3 TVs, computer. I have had the unit for 1.5 years and it has performed flawlessly!

Our 20 KW Guardian ran and provided power to our whole house for 156 straight hours. This was in the aftermath of Hurricane Laura here in north central Louisiana. Came on automatically 10 seconds after the grid died and we never missed a beat. We installed this unit when we built our house 10 years ago and it has always been reliable. We live rurally so we've had to rely on it on multiple previous occasions. The longest prior to this was 4 days after a tornado. Some neighbors will be getting Guardians soon. Just have it installed and serviced by professionals recommended by Guardian and you're good to go!

Great item, installed by a Master electrician works great. No problems som far. Owned itnforn 2 years.

Installation was quick and easy for the contractor. Price was great. No reservations to recommend to others.

Unit has performed as advertised. After first long run (28 hours) noticed oil leak. Had a cracked head which dealer repaired and serviced at no cost. Since repairs no issues. Generac stands behind their products.

Had our Generac guardian in stalled 5 years ago. It has ran perfectly. Many times we have had the power go out and our home has been the only one on the whole area lite up with lights. It runs the whole 7,000 square food with A/C units and all.

I am in a wheelchair, and this Power system with auto on/switch over is perfect, and I would recommed this to all, and I have. We a very, very satisfied owners.
