Make home standby backup power more affordable. Apply here for financing.



Home Backup Systems opened in 2006 to serve the local Fort Atkinson and surrounding areas with quality standby generator sales and service. Since that time, we have added additional offices in Appleton, Mosinee, Elcho & Rhinelander and our territory has grown to include all of Wisconsin, northern Illinois, and the Upper Peninsula of Michigan. We have also expanded to serve as the generator service provider for a large number of Home Depot and Costco stores across Wisconsin. Here at Home Backup Systems, we know choosing a standby solution is a complicated process, so we spend a lot of time prior to any sale, ensuring our customers have a complete understanding of how it works and all of the options available. This helps us to partner with our customers to ensure they are getting exactly what they need. We offer full installation services, parts, warranty service and repairs along with annual maintenance service and agreements.

Home Backup Systems were fantastic to work with! Mariah who quoted the job, Allison, Steph who coordinated the project had great communication. The installation with Dave the electrician and the Home Backup guys Seth and Nolan went smoothly. They did a great job communicating, were very friendly during the install to answer all of my questions. I was given an overview of the Generator, how it operates, and felt very comfortable when they left. An awesome install crew who work great together. I highly recommend Home Backup for your Generac installation.

From start to finish, the staff did an excellent job. The office staff kept me informed on time lines and schedule. The installers of our new generac were extremely friendly, helpful and knowledgeable. Hats off to them for working outside on a very cold and windy day. Very pleased!

Could not be happier with the service from HBS. The gentleman that I met for the estimate was professional and knowledgeable, the install crew was excellent! They were very friendly, and patient with me (I know I tend to hover when projects are happening 🤣). They did a phenomenal job and cleaned up very well after themselves. I was pleasantly surprised that start to finish the install only took about 4 hours and everything looks very well done. Hats off to you guys!!

Needed to resolve an issue with my generator and called HBS. They were quick to get here and the service was outstanding! Highly recommend!
