Manufacturer Review
20kW PowerProtect Generator
By Tim L. 
Briggs & Stratton Sales Manager
Review Posted 02/08/2022
With no deration on natural gas, this is a true 20kW generator making it the most powerful in its class. Sleeker, quieter and more powerful than ever before, these units are designed to keep your whole home powered no matter what's going on outside.

The 6-Year limited warranty includes parts, labor and travel for the entire term of the warranty making it the industries most comprehensive warranty.

Review Posted 12/05/2023 
This 20kw unit is very powerful and a great value. Its smaller footprint vs other generators companies sizes makes it easy to install. The no special tools feature to remove panels and get to all the components is niceI and I like the new weekly exercise feature. it only runs once a week for a quick less than 30 seconds test. Saving money on propane vs traditional 10-20 minute test runs like other companies. I like the 6 year non-prorated warranty. Meaning unlike other companies, B&S covers the unit for a full 6 years!

This generator runs excellently and during the weekly exercise, less than 60 seconds testing it runs at half RPM's and is super quiet. The 6 or 10-year warranty is fantastic, it's not prorated like some other companies.

I saw that someone else wasn't happy with some troubles they were having. Yes, there were some software updates that needed to be done and our service guy had the right computer tools and software to update the control board and the voltage regulator the same day. It was something about the weekly exercise glitch, but bam this guy knew what he was doing and the issue was taken care of.

It's like getting a new computer and once you turn it on from the factory it pops up and says "hey new software update is needed." Glad we have it! PS we replaced a Generac unit for this Brings and Stratton.

Overpriced And Fails Weekly Exercise Tests
By J. A. T.

Review Posted 10/11/2022 
I have the "new" 2022 version and mine keeps failing its weekly exercise with an AVR Fault. Service techs have downloaded new software, still fails. It is a piece of junk. Would not recommend. It ran during a recent power outage & the engine did not sound right. The technician couldn't find anything wrong with it.
