Essential Equipment

Get this generator! Here in northern New Jersey power outages are a fact of life. Some last minutes, others last WEEKS. Our Generac kicks in automatically after only a few seconds and powers the entire house. We have our heating, cooling, lights, communications, and even our entertainment. But what is truly priceless is the peace of mind we enjoy knowing we have reliable and always-ready backup power. Generac is the king of generators for one reason - they're the best!

A must have!

I purchased a 20 kw generator with the Nexus Smart switch. I live on the water on Long Island's south shore. I was hit with Frankenstorm Sandy and my generator was swamped with salt water. when the storm ended I doused it with fresh water and WD40. I had it turned off as the storm hit. I removed the spark plugs and pumped out the water. I also changed the oil. I charged the battery and to my surprise I was able to start the generator. With fire extinguisher in hand I energized it and it was putting out electricity. I had it running for 13 days straight because I knew it would not start again. The starter was ruined. It ran like a top and never burned a drop of oil. Thanks Generac you made a great machine!

Exactly what I needed for my home office!

After being without power for over a whole week during the Northeast Blizzard of 2010, I promised my family that I would do whatever it takes to make sure that we didn't have to experience that situation ever again. Thank goodness for my wife and her willingness to melt snow on the outdoor BBQ grille so we could have water to flush our toilets with. NEVER AGAIN! My new Generac 20kW generator keeps my well pump running, my A/C humming, and my home office buzzing. My longest outage since installation has "only" been about 6 hours, but just the peace of mind that it gives my family makes it worth EVERY DOLLAR that I spent to have the system setup for me. THANKS GENERAC!

Reliable, dependable generator

We live on top of a mountain in SC, where we lose power during an ice storm once or twice a year. Having a reliable, dependable generator makes all the difference! Once, both my husband and I were recovering from surgery. Losing power would have been dangerous, but thanks to our generator, we were safe and comfortable. Well worth the money for the security & peace of mind!

On backup now

I have had the 22kw gen for three years now on a 5500 sq foot home. Initially we installed for partial usage but wired for whole house. With 3 ac units, two refrigerators and all lights on the gen is using 80 percent max current! I have had only one shutdown event when it was 103 degrees outside and I tried to run two ac units, it overheated. Wish the home link was more real time (delayed) and was more interactive otherwise great backup gen!

Quiet Operation, excellent product.

Very impressed at quiet operation of the 20kw Generac generator. The case adds to the overall appearaance of the property. I would highly recommend it to anyone. In the trial we were very satisfied with he way it kept a steady flow of current when the test was ran.

Wonderful Generator!

I just bought this Generator and had it installed and I must say that I am quite amazed at not only its sleek look and quietness, but at it extreme efficiency and the way it works. I don't seem to have to worry about a thing and I love that! Thanks Generac!!

Excellent product

I purchased the 20KW Guardian Series in October of 2013. I have it serviced twice a year, and it has never let us down. It does its own weekly test and there are coloured LED indicators on the side of the generator that will indicate the "state" of the generator. We had an outage for 18 hours on Christmas Eve last year......and we didn't care!!!

Excellent Product

Although my generator is only a week old, it was called into action during another South Carolina thunderstorm. As the lights flickered, my wife and daughter both asked: Will that generator work???? In just a few seconds, all was well and we were thanking our great provider for doing such a wonderful job for us. As the texts from neighbors rolled in, I was happy to tell them that we were COOL and safe!!!!! The generator is pretty quiet and looks great with its low profile. We are ready for hurricane and thunderstorm season!!!!!

Very satisfied with unit & Metro Electric installation Crew

More than pleased with the efficient manner of the installation team that installed my unit. They have the procedure down and worked very well together. So far the unit has only run on the maintenance schedule and has performed as required. Waiting to see if it will perform as required on an actual power outage.
