Meet the brains behind your home generator. The ATS is always monitoring your home’s power.
During an outage, it automatically transfers power from the utility to your generator. The ATS restores your home power to the utility grid and turns off your backup power when the main power comes back on.
A home generator plus installation can start at $6000. Your total cost will vary based on your installation and power needs. When shopping for standby generators, your checklist should include generator installation, costs, accessories and permits. No need to worry, your KOHLER dealer will handle all the details, so you don’t have to.
Power outages can be expensive. Extreme weather is the leading cause of power outages in the United States. Over the last ten years, power outages have become more severe. We’ve seen more frequent and longer-lasting blackouts, which can cause loss of time and money.
These surges have caused damage to properties and homes. This has resulted in physical, emotional, and financial difficulties for many Americans.
Home insurance rates may be lower. Insurance companies may offer lower rates for homes well-protected against theft, flooding, and severe weather. Your backup power keeps the lights on, the security system working, and the sump pump running smoothly. This provides peace of mind for both you and your insurer.
