Storm Protector

We bought this 22kw about a year ago as our 20kw oil pump failed during a week plus ice storm running 24/7 continually due to extreme trees/down/ice power outage. Had no choice but to replace. We live in Northerm Michigan and Generac IS A MUST!

Best generator on the market

I researched all kinds of generator and decided that general was the best one for what I wanted to use it for. I could not ask for anything more,it runs the whole house.

Completely Reliable Generator

Our generator went on automatically during the five power failures (too many) in the past year. The longest of those failures lasted several hours. The generator gives us the protection we needed.

Excellent workmanship

Experienced power failure since installation. Generator kicked in and powered up entire house as advertised.. Scheduled weekly test runs have been occurring on time. Great investment. Mobile link should be built into equipment.

Peace of Mind

It is very comforting to know that the generator is installed and ready to go. One of those things you would rather have and not have to use, than need and not have.

A very professional looking package

The unit is compact and is much smaller than I expected. I expect its quality and efficiency to match the obvious quality of its design as well as the components supplied. The installation by a local contractor went smoothly.

Excellent Product

Very pleased with the installation and operation of our 22kw Generac back up generator. Everything is operating as expected and we are actually kind of excited to have our first power outage! Well done.

Great Unit

The only issue I've had with the unit is the engine surging up and down when we have high humidity. When the air is dry and we have low humidity the unit works great.

Generac Home Generator

We purchased our generator in March of 2026. Although we have not had a need for it yet, we are confident when we do need back up power it will work as designed. We were very happy with Storm Electric who did the installation.
