GUARDIAN 11 KW GENERATOR FEATURES AND BENEFITS

  • Generac OHVI® EngineYour Guardian Series generator might have to get you through days—or weeks—without utility power. Generac’s OHVI® engine, specifically designed for generator use, provides the reliability to power through the most severe outages.
  • True Power™ Technology - Best-in-class power quality with less than 5% total harmonic distortion means clean, smooth operation of your sensitive electronics and appliances.
  • Evolution™ Controller - The next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons.
  • Certified for 18" Installation to the Home - Third-party certified to NFPA standards to be installed as close as 18” from the home’s exterior wall, provided it is located away from doors, windows, and fresh-air intakes, and unless otherwise directed by local codes.
  • Easy Installation - When combined with a pre-wired transfer switch or Smart Switch, re-engineered connection points, and composite mounting pad that eliminates the need for a poured concrete base (unless specified by local codes), the Guardian Series 11 kW generator is easy to install.
  • Rated for Operation in Areas with Low Natural Gas Pressure - In areas with low natural gas pressure, the Guardian Series 11 kW generator can operate on natural gas pressures of only 3.5” of water column.
  • All-Weather Steel Enclosure - Our durable powder-coat finish helps make the sturdy, Galvanneal steel enclosure perfect for all weather confitions. It’s also able to withstand 150 mph winds. Optional aluminum available, recommended for salt-air locations.
  • Tool-less Fuel ConversionSwitch between natural gas and LP fuel in the field in a few seconds, without the need for any tools.
  • Quick, Quiet Exercise Test - Standby generators require a short run-time periodically, known as exercise, to test and ensure the system is functioning properly and ready for an emergency. The Guardian 11 kW self-test runs for only twelve minutes. Choose your schedule - weekly, bi-weekly or monthly.
  • Mobile Link™ Compatible - Take advantage of Generac’s Mobile Link cellular remote monitoring system and check on your generator’s status using your computer, tablet or smartphone, even when you are away. Sold separately.

Excellent product for the price and reliabilityReview by Jeffrey55
Quality
Overall
I purchased 4 generators for myself, community well and two neighbors. All are satisfied with the reliability, price paid and functionality provided. In 2.5 yrs I have never had a problem with the uniit and have had to rely upon it in all seasons --particularly a New England winter. It started, ran and stopped just as advertised. Easy to install and service. I change the oil, plugs and filters as required and it takes less than 30 minutes. A great machine that is reliable and the best part is that when the power fails--I don 't have to do a thing. The transfer is almost seamless. The lights, furnace, etc stay on. Best idea since the wheel was invented. (Posted on 8/4/2015)

After several outages, two of which were thirty-six hours, this unit has paid for itself.Review by docfps
Quality
Overall
We live in a suburb of Chicago which in the past had very few power outages. In recent years, the outages have increased. After an outage last year which lasted for two days, and for which we used a portable generator, we decided that we needed an automatic unit. We have ceiling fans, so we decided not to get a unit that would handle the air conditioner for our two story home.
This year we didn't have a worry in the world when within a two week span we had two outages, both of which lasted about thirty-six hours.
We have recommended the Generac Guardian to our friends, neighbors, and relatives. We couldn't be happier with this purchase! (Posted on 8/2/2015)

THis product Saves The DayReview by Spoonman
Quality
Overall
We purchased this unit after having endured the major ice storm which struck the Northeast in December 2008. It was extremely cold then and we were fortunate that our power came back on after 36 hours as others waited up to two weeks. The next summer I ordered this unit and it's been wonderful every since. Our longest outage since I had it installed during winter has been 19 hours and our Generac has performed flawlessly. On a number of occasions during the summer it has powered up when our electricity has been out and run a couple to as much as 6 hours. Since we both work at home, its ability to start delivering power within 10 seconds has meant no shutdown of our personal computers and that has allowed us to remain productive and meet our clients needs.

I recommend these Generac units strongly based on our personal experience - they are the best! I will never have another home without one. (Posted on 7/31/2015)

Installed July of 2010 easy installation. Only ran for the exercise cycle for most of the first year, never lost power. In May of 2011 lost power for 30 hours generator never skip a beat, People in the area lost everything they had in their refrigerators. Went out to check on generator after running 30 hrs and noticed it had a small oil leak. In the process now of trying to get it fixed before winter arrives. (Posted on 7/20/2015)

Worth its weight in gold!Review by suzycrampton
Quality
Overall
We live in a rural area that loses power a couple of times a year. The last time we lost it for 4 days, with the power coming back on Christmas Eve. When we lose power, we lose more than just lights, heat, we lose water, and sump pump power too. If we are home, we will have power, if we are gone, we don't have to worry about the basement flooding. It blends in with the house, does not stick out like a sore thumb. Love seeing it sit there with the green light on! The generator not only gives us power, it gives us peace of mind too. (Posted on 7/16/2015)

I used to have a smaller Gas Generator. When the power went out I had to get it out, set it up, gas it up, all the usual
checks before starting. Then hook up the electrical devices I wanted to powerup during the power loss.Time consuming!!
Then when the power came back on, the same rigamarole in reverse.
I'm older now and don't need the problems.
I bought my Generac from lowe's, had it professionally installed.
Now everything is automatic, my wife and I love it. It has not failed to operate when it was called for..... Wonderful!!!! (Posted on 7/15/2015)

Quality
Overall
Albeit, this is a very new review, but we are exceedingly pleased with our new generator. Install went easy, delivery (from Lowe's) was super excellent. All in all so far this has been a good experience. I would recommend this product to anyone.

Only complaint, if you can even call it that is we ordered back in October 2011 and just received in March 2012. I understand due to the increase in bad weather everywhere. Maybe generac has resolved this problem by hiring more people, based on increased demand.

I guess this is evidence of a good product though. Thanks. (Posted on 7/1/2015)

Peace of Mind ... Only change one thingReview by Snafflehound
Quality
Overall
My father bought a 15kW propane Generac 20 years ago in NC and it has performed flawlessly through numerous ice storms and outages. When we moved into a new home in a Seattle suburb known for outages due to downed trees on power lines, I bought 10kW Generac and have hardlined into gas lines. It has performed wonderfully for seven years through quite a few outages. Only time it didn't was when battery died. It'd be nice if there was an alarming feature that let's you know when battery is too low or that the weekly exercising it does failed. We have a son with disabilities so need power for medical reasons. Its a relief to know my wife will have power within 20 secs if there is an outage and she doesn't have to wheel one out, plug it in and keep it gassed up. Well worth the money.

The one feature I'd change more flexibility in managing the power during an outage. When we had it installed, we had to choose to power either the washer/dryer or double ovens. It'd be nice to have the ability toggle back and forth during an outage and use one or the other but not both simultaneously. (Posted on 6/16/2015)

I am sleeping through the night..Review by SleepingAgain
Quality
Overall
Moved into our dream house only to find out that the entire neighborhood loses electricity 3-5 times per summer. With a sump pump that never quits, this is totally unacceptable. End result, we are stuck at home sleeping with one eye open waiting for the power outage and the sprint to a generator at best, the bucket and pails at worst...
Installed the Generac 10kw and lost power in just over a week. I was in the shower getting ready for work. I paused for a minute to listen to the generator kick in and resumed my life. This is the way life should be...
It has run 4 times since. It runs hot, but that seems necessary. I thought it would be a bit quieter, but this seems like a small complaint compared to the sense of peace it has brought.
Only time will tell about maintenance and longevity. But if you are looking for peace of mind, go buy it. (Posted on 5/21/2015)

Great during Hurricane Irene in CTReview by Sam S
Quality
Overall
Hurricane Irene hit CT on August 28th, 2010. That morning at 7 am we lost power. The unit detected the power outage and kicked in as scheduled 15 seconds later. Then it ran... and ran... and ran... until August 31st at 1 am. After all that time it burned through only 40% of two large propane tanks (80 gallon tanks) and it could have run another three days easily (6 days total). Since it is on propane, it is relatively quiet to the other units in the neighborhood. It was trouble free and gave very even output no matter what the load was on the unit with its 20 circuits. For a 3500 square foot home, including the basement, it powers about 65% of the devices (lights, water pump, septic system pump, electronics) and makes staying in the home easy while my neighbors either (A) went to hotels or (B) struggled with their portables, refilling their tanks every 6 to 8 horus of use. I recommend this unit as you will be hard pressed to do better. (Posted on 2/25/2015)

Hurricane IreneReview by cullinan18
Quality
Overall
I just got power back after 54 hours of downtime from Irene. I was the only house with power those 2+ days and since we all have septic and wells, I offered showers and water to the neighbors. My sump pump worked overtime and I didn't flood. Having a standby generator was the best idea.

This is an internal combustion engine. It makes noise. You will hear it running. It won't make your ears bleed, but you will hear it drone and it can be annoying overnight. Hey, turn it off if the noise bothers you. It's much quieter than a lawnmower and it saved my house and make my family comfortable. I recommend generators to all my friends and family, especially to those bailing water out of there houses. (Posted on 2/16/2015)
Great product... and FYI ...Review by Hank14
Quality
Overall
My house runs on propane, so the generator is hooked directly to the propane system. It has been in place about two years and works great! Have gone through several outages, and it kicked on flawlessly. The weekly test run is set at 10:30 AM (11:30 in daylight savings time) on Mondays. I checked with the local Generac agent who installed it to ask how much propane the generator uses per hour. He said (if I remember right) it uses 3 gallons an hour. I have a 500 gallon propane tank so if I ever have an extended outage, I plan to turn it on and off over time. The refrigerator and freezer will chill back down, everyone will rush to get a shower, etc.

The FYI is ..
I have a checkoff list to prep for vacation trips (stop the mail, etc), and I added turning the generator off to the list. Otherwise, a days-long outage could deplete my propane tank. An owner should consider how to handle such a situation. My answer was to turn it off, others might want to have friends monitor it. (Posted on 2/12/2015)
Every home should have oneReview by James B
Quality
Overall
Although I have most of the house on the system, I bought this unit primarily because I have a high ground water issue to deal with most of the year. I have 4–3/4h.p. pumps in my crock and at certain times during a wet and rainy spring thaw all of them may be running. Prior to getting the generator, I have had varying degrees of basement flooding to deal with a few times and the amount of anxiety could be overwhelming when a storm is in the forecast and the pumps were working hard to keep up with the water flow. Now I can sleep without the worry.

As far as installation goes, most electricians are going to charge anywhere from $1000 on up and then the plumber isn't cheap either to hook up the gas line. Gas has to be lead to the unit, so unless you have an existing gas line already in place, the plumber has to lay pipe and your natural gas supplier may have to upgrade the meter for the extra required gas flow to run the unit. My utility did the meter upgrade for free but the plumber had to install limiters on the water heater and furnace. Total cost for install was just under $2000.

The unit looks great, self tests every week, and providing I maintain the unit, it should last my lifetime and improve the chance of selling my home to the next owner. As far as value for the price.... a total investment of just under five grand isn't cheap but does allow for peace of mind. What 10K generator priced at $2700 is a bargain? Probably none, but there are few other options available. (Posted on 2/3/2015)

Great Backup GeneratorReview by SEK450
Quality
Overall
This unit was purchased and installed 2.5 years ago. It still works as advertised in a residential area. It has been been needed and used approximately 24 hours in this time frame for anything as short as 10 minutes to 4 hours. I have all essential home equipment and services on backup as well as many non-essential services. I also have exterior plugs available to run extension cords from for neighbours if need be. I suppose noise could be an issue however, I feel it is a matter of priorities. As I do live in NS, Canada a cold weather kit is essential to ensure proper operation in the winter. I have a 3500 sqft 4 bedroom home and this meets all of our needs. At most I would recommend a 17KW unit if you can get one at little above cost. Costco in Canada now has them and I am considering swapping to the larger unit. Overall, our experiences with this unit have all been positive. Great deal, quite satisfied. (Posted on 1/21/2015)
Got us through Hurricane SandyReview by 1zondo
Quality
Overall
After being without power for 6 days following Hurricane Irene, we decided to invest in a natural gas powered house generator. It was our best investment ever! Following Hurricane Sandy, we lost power for 8 days, and our Generac generator made it bearable. We had heat, water from our well, hot water to shower, didn't lose any food. We were taking in lots of our neighbors. So happy we made this decision. Highly recommend! (Posted on 12/30/2014)
A great unitReview by inkycat

Overall
We installed a Guardian backup system in 2002. It has operated flawlessly for a decade. The only maintenance has been oil changes and air filters. We have replaced the starting battery twice. We are thinking of moving up to a 17 kw unit. My only regret is that a stainless steel housing was not offered as an option. (Posted on 12/24/2014)

Being on oxygen 24/7 it was impossible for me to set up a portable generator and keep it fueled. In the three outages since it was installed, my Gererac has run flawlessly and has provided great peace of mind. (Posted on 12/14/2014)
This is the Best GeneratorReview by Modar
Quality
Overall
Well the only down side was the electric contractor I hired to install this generator. They made a 4 hour job into a 8 hour job (WTG). Other than that, the generator preforms like a dream. During the test they shut off my electric and within 10 secs the generator kicked in and the whole house had power up. When they turned the power back on you could hardly notice that the switch took place. It was smooth and quick unlike the electric contractor. Before you hire someone to install this, be sure to check around and ask lots of questions. Like: Do you know what your doing and get it in writing. This is the best though even though I had to put up with that part of it. Here in Alaska you have to get the cold weather package...a real must. I'm loving it. (Posted on 12/9/2014)
This generator has performed as advertised.Review by Happy in NY
Quality
Overall
We installed this in the Fall of 2010 as a back-up for our basic electrical circuits. I travel for work and it gives us the peace of mind that my wife will have power in the event of an outage. It has only been needed on a few occasions for up to an hour, but it came on when needed. I like the idea that it runs once per week and lets us know if it did not function properly.

It was installed between our house and the neighbor's and noise is not a problem. It runs quieter than most portable generators.

I would recommend a Generac generator to anyone looking for a stand-by unit. (Posted on 12/8/2014)

After my basement flooded twice I added more sump pumps, but if the power went out we still had problem. The stand by generator has solved that problem. It really gives us peace of mind, and works great. (Posted on 12/2/2014)

We've had several short (less than five hour) outages since buying our Generac. It has performed flawlessly. I no longer worry about an ice or wind storm leaving us in the dark for days as has happened years ago. (Posted on 11/30/2014)

The auto transfer switch is great. we are very pleased with our purchased. Highly recommend generac generators. (Posted on 11/20/2014)
Poor first impression; time will tellReview by windham8
Quality
Overall
Unit installed and tested ok, but during several subsequent weekly tests it would not start, and showed the "stopped-alarm-overcrank" notice. The installer found that the unit shipped WITHOUT its air filter, and that the butterfly valve for the choke was damaged and had to be replaced. This took several weeks and calls, and one power outage when it did not work. This was extremely stressful, and for weeks after we dreaded the weekly tests. It has been several months now and we are hoping all is well but we were not at all impressed with this unit for the first few months. We don't blame the installer; the air filter is hidden away and there was no reason for him to question if it was there or not.
Love the concept of a generator that runs on LP gas, turns on automatically, and all that simplicity, but it would take a different initial impression to give me the confidence to recommend this to a friend or neighbor. Many are in the market, after Irene. (Posted on 11/18/2014)

The quality of this product far exceeded my expectations. I found the installation a little confusing since it had no detailed instructions for hook up using the Nexus 200 amp whole house transfer switch. My unit was slightly damaged during shipment (no fault of the Manufactor). I actually wondered if maybe I was missing some of the installation materials and or instructions since the unit had been opened, but I did not check to see if my thoughts were correct.

I wish I would have gotten this sooner. It is nice to have the piece of mind. The 10K unit does everything I need and more. Typically outages are a day or less but we had a 4 day one. I really appreciate knowing my family has everything they need in an outage. The unit is very quiet compared to portable units. I would definitely recommend this to anyone in the market for a back-up generator. (Posted on 11/3/2014)
Great product for home emergency powerReview by Rad

Overall
I have been quite happy with my Generac generator. It has been reliable, easy to operate and maintain. The one feature I wish it had was the ability to set how often it ran for its regular operational check. Weekly operational checks may make sense during the winter (stormy) period but are too frequent for the late spring and summer periods. (Posted on 11/2/2014)
