Survivability in a hurricane prone area

I previously had a portable emergency generator that helped me through a few hurricanes. I retired a few months ago & built a house on my rural property 100 miles away. Two years ago that area suffered a couple of bad storms & the community was without electrical power for weeks. I now have my own well & electrical system. Storms as we have in Southeast Georgia will not affect me as much in the future.

Great product

Bought this generator about 6 weeks ago. The install was completed without any issues or concerns. Final connection was completed after gas company upgraded the meter. We had a power outage about 2 weeks after the install and never noticed the power going out. The generator started so fast there was never a flicker of the lights.

Easy Set up

I had a 5000 watt generator( 13 horse Briggs and Stratton ) I bought for Y2K and this is a huge upgrade for me and I only have to hook it up once this time. 😊. It's always ready for me now. Thx. 😊

Should have done it sooner

We thought about getting a generator for many years but it seemed like a lot of research and a lot of money. After 20 years we finally put one in last spring. It was a considerable investment but so far we are pleased. Ours comes on every Wednesday morning and does the trial automatically which gives us some confidence. We've only had a few brief electrical outages and it did come on as needed but wasn't needed for a long time. When a larger outage occurs I feel confident that it will work and that our home can be the gathering spot for those without electricity.

Very reliable

My unit has kicked in multiple times since our purchase, be it minutes are hours. There is a minimum loss of power from outage to generator transfer. When power restored, there is no "blink" to indicate house power back on. Once a week , as scheduled, it starts up to run a five minute test.

Priceless...

When we lose power here it's generally for an extended period of time (several hours). After dealing with a portable generator for years, we finally purchased a Generac 22kw automatic generator. Now there's no wheeling the portable out, filling it with gas, hooking it up and hoping it will crank, most often doing all the above in lousy weather. The very day the installation was completed we lost power for 10 hours. The Generac came on during that time and ran flawlessly. On top of that it was so much quieter than the old portable that it could barely be heard. We love it. I only wish we had made the commitment to purchase years ago. I highly recommend the Generac.

Great "Insurance Policy"

At this point, my review can only address the installer and the installation of the generator. We've not had a power outage since its installation, and frankly I hope we never have to use it. It's an insurance policy against what has happened all too often causing distress over not having water (well pump) and the potential loss of food in 4 freezers & 5 refrigerators and the further annoyance of not being able to turn on the TV & see the news. Expensive insurance - Yes, but it's comforting to know that when (not if) the power goes, our Generac will come alive!

Love it more every time it's activated.

We live in a wooded area and power goes out frequently. I love the peace of mind that our Generac generator provides. If it goes off at 4:30 in the morning, it activates quickly enough that our alarm clocks don't even need to be reset. Very reliable.

My Generac Emergency Power Unit

Actually, aside from it looking good, We have no idea how well it works. We have not had any type power outage since installation. Further, we have attempted to "be there" when the unit initiates its bi-weekly "process". As yet have we heard it start up. Therefore, we're unsure if it works. We've contacted the consultant and he checked the time & date and the schedule and pronounces it "good to go". so, at this time, we are in a "wait & see' mode.

6551 buy / diy install first review

Pretty straight forward install. My actual costs were about half what a pro quoted not including chasing parts and my labor. Commissioning was straight forward also. Notable notes: Im not 100% satisfied on the auto start. The engine start takes longer than i like and it stumbles a bit. Plan to recheck gas service. Its also a bit louder than expected. From pre buy conversations with local dealers i dont expect much support either because i didnt give them the total sale. Consider that before you buy from a wholesaler.. I will review again after the first power loss.
