Great product!

I purchased this 09/03/2025 and I have been very pleased with the Generac 14KW unit so far. During the "daylight" hours, I didn't even notice that the power went out until I heard the Generator running. The first time that happened, I called CMD Power Systems all in a panic because I thought the generator was running for no reason. Embarrassing enough, the Generator was doing its job! I felt so foolish and apologized for being such a "new" panicked customer.

Reliable Backup Power When It Matters Most

A major storm knocked out our power for days, so I finally decided it was time to invest in a generator. Just having it sitting there gives me a sense of security—like no matter what the weather does, we won't be left in the dark again. We haven't needed to run it fully yet, but when the next storm rolls in, I'll feel a lot better knowing it's ready to go.

Aesthetically pleasing

I installed the unit myself completed the install at the end of August 2026. To date we have not had to rely on it for power but I'm confident in the fact it will perform as intended

Poor installation

I bought the unit a month ago and I had to contact the salesman about the poor installation. The generator was bouncing across the pad when it came on. The crew came back the next day with Billy to add more dirt underneath the pad and added anchor screws to hold the unit on the pad. Billy promised he would come back to landscape the dirt to prevent erosion. But nobody has returned and recent rains are washing the dirt away!

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.

Generator works fine - WiFi unreliable

The Wifi connection had to be replaced with a module that allowed for Ethernet connection cable. All customers I talked to tell me the same issue. The Wi-Fi will not connect and stay connected. When we have had shorter power outages, I would like the generator to wait at least 20-30 minutes before going back to Utility. It has to be much harder on the equipment going on and off too many times an hour. It has operated fine otherwise.

Happy with our Generac

We purchased our Generac from Calibre Electric in Burlington, Ontario. The install was done quickly and the techs were courteous and showed me how to set up the Generac Mobile Link on my phone so I can monitor the machine. A few weeks after the install we had a half day power outage, the generator kicked in promptly and my wife had AC so all was well. It runs a little noisy but with the windows closed we didn't mind. I would recommend to gardeners that you not locate your machine close to plants, as the heat from the exhaust will not be kind to your garden.

Generator performed perfectly.

We had a bad thunderstorm yesterday and lost power for a couple of hours. Our generator came on and worked perfectly. We would not have known the power was off and the generator had taken over if it had been for us hearing the generator running and the light blinking. I gave a 5 star rating because of the way the generator has performed even though I am still not happy about being put off about the damages,

Great product and must have

We purchased this unit in August 2025 and are very pleased with its reliability and performance as we have had five power outages with no issues. Highly recommend this product
