I had an older Briggs & Stratton home standby generator and it failed many times. I spoke with the dealer who said it’s old and should be upgraded. I purchased a new 12kw unit last summer. Just lost power and guess what, the new unit failed. Has an AVR fault. If you want reliability, don’t buy a Briggs and Stratton.

Just the right size
[This review was collected as part of a promotion.] We’ve had our standby generator for 6 years. Peace of Mind and the ability to maintain our life style are priceless.

[This review was collected as part of a promotion.] Turn key installation. My power company put it in. Runs on LP gas from a 500 gallon tank, so we should have plenty of time if the power goes out. It exercises itself once a week for 20 minutes.

Looks nice, runs quietly
[This review was collected as part of a promotion.] The unit looks nice and runs quietly. We have yet to have a power outage so that has not been tested yet!

Love it
[This review was collected as part of a promotion.] This generator came with the house when we purchased our home. This is a must have! During the summer months when there are brown outs this kicks on seemingly.

Plan for The Worst
[This review was collected as part of a promotion.] We had several outages last year, one for 55 hours so it was time.

Evolution in Standby Generators
[This review was collected as part of a promotion.] Installers have finally finished the Symphony II Transfer Switch to my 12KW B&S Standby Generator. Electrician is stunned at the cleverness of this system - easy to install and whole house (using modules) service! My wife and I are thrilled and can hardly wait for a power outage!

awesome
[This review was collected as part of a promotion.] I bought this 3 years ago, always nice to know when the power goes off I have lights in about 15 to 20 seconds. Running natural gas is the best. My only complaint is just a couple of months after my purchase they started gving a 10 year warranty, I only have 6 years.

Very reliable
[This review was collected as part of a promotion.] Very small footprint compared to other brands but more difficult to access the filters and other normal maintenance requirements. The ability to connect to my NG service was extremely important.

how do you switch it to LP. Is it a orifice that needs to be changed or just a button switch?
