I love the automatic start!

Would Recommend

I have had it running for about year and a half, I do like the generator in general, starts and switches very smoothly, and shuts down once power comes back up very well, great protection. The App I have not been able to connect to generator.

Great except the battery

It’s great to have a backup whole-house generator for emergency situations. The only negative is the battery only lasted one year. I have a five year warranty and the battery isn’t covered.

Not the first, wont be the last!

Would Recommend

Our most recent purchase was a replacement unit for fhe original used unit we had for 10 years. We did not even hesitate when it came for the replacement. Our first unit was about 5 years old when we got it and it lasted another 10 years and was an absolute blessing when we needed it. So happy we installed a whole home generator shortly after we moved in!
