Generac Whole Home and Commercial Stand By Generators – “Keeping Life Normal”

Whole house generators are the proactive way to ensure electric supply at any time. Generac models come in a range of sizes, and can power an entire home or the circuits you want. Generac is the world’s leading manufacturer of residential backup generators, and sells five times more products than all other makers combined. Diederich Electric has been in business since 1991 and offers a number of reliable home, commercial, and portable generators.

A standby generator serves as a backup to a home’s electrical system, and operates in the event of a power outage. Most Generac generators use natural gas or liquid propane as a fuel source which allows them to turn on within seconds of a power outage, and then off once power is restored.
