Briggs & Stratton 12KW Installed Generator

Gain the peace of mind, and quiet that comes with owning the new 12kW generator by Briggs & Stratton. Now 60% quieter* and 50% smaller than our old 12kW, you don’t have to compromise your homes curb appeal to get the protection of automatic backup power. With its sleek, compact profile, the 12kW Home Standby Generator adds new dimension to “Powering More for Less.” Perfect for smaller to medium-sized homes, the new 12kW Generator by Briggs & Stratton combined with our Symphony® II Power Management System allows you to meet the power needs of your whole house, (including up to two 4-ton air conditioners).


Why the Symphony® II Power Management System? Well, not all appliances are powered equally. Some, such as your central air conditioner, electric clothes dryer, electric stovetop, oven, or whirlpool tub, require a large amount of power to start up or operate properly.

The Symphony® II, featured on the 12kw generator, orchestrates these high-demand appliances with lower-demand items to give you true whole-house power with a smaller, more affordable generator. The package also includes one of the best comprehensive parts and labor warranties in the business – 5 parts and 3 year labor year limited warranty your guarantee of quality and performance.

We Recommend Based on Reliability

Dunn Electrical Service chooses to work with only two generator manufacturers for a reason. When it matters most you can rely on Briggs & Stratton and General Electric brand generators to deliver power when your service area experiences a power outage. You can shop based on price however, we recommend based on experience.

Dunn Electrical Service stands behind these recommendations based on hands-on experience being on-site with customers when an (alternate brand) generator fails to deliver power in an emergency. Your safety and the convenience of having continuous power is a matter of reliability and confidence rather than which generator is the lowest price. Lower priced products can often set you up to fail when it matters most. Call or contact us to today to discuss your needs, so we can make a solid recommendation to meet or exceed your emergency power needs.
