Residential and Commercial generators - Install, Sales, and Service 

Unlike a portable generator, you don't have to go outside, run a maze of extension cords or bother with gasoline, because an automatic standby generator operates on your LP gas or natural gas supply. Plus, when utility power returns, the generator automatically shuts down and waits for the next outage. 

  • No gas cans 
  • No extension cords 
  • Totally hands-free operation 

Owning a GENERAC automatic standby generator has never been more convenient or affordable. 

Powertech Electric offers a wide line of residential and commercial generators that can keep your home or business running when the power goes out. 

From helping you select the right size generator, to installation and service down the road, you can rely on the Powertech team to keep your power on!
