Commercial Generator Services

A strong storm, a power line accident, or a power surge are all possible phenomena that could cause a power outage for a business. In Maryland, Northern Virginia, Washington, D.C., and Pennsylvania, high winds or accidents could hit any year. When managing your business during such events, you are responsible for preserving the well-being of many more occupants and supplies than you would in a house. That’s why TriStar Electric provides commercial generator services in Maryland and surrounding areas. Learn more about our commercial generator services below, and see how we can help your business thrive with or without power.

Commercial Generator Installation, Maintenance, & More

TriStar Electric is an Elite Level Generac® Dealer authorized to distribute and install commercial generators. We have installed and maintained residential and commercial generators for decades, and there is no better brand to do it with than the country’s largest generator manufacturer. Generac’s generators are famed for their reliability and ability to get you through the entire power outage and not just a part of it.

TriStar is happy to install, maintain, and troubleshoot your business’s Generac generator. We do not offer an emergency repair service, but our maintenance service will ensure that your generator will work when you need it to. If you have any questions, please contact us for more information!

Types of Commercial Generators

Generators vary based on different fuel sources, sizes, and control types.

For power, you can find these types:

  • Diesel
  • Natural gas
  • Propane

Different sizes range from 10kw-200kw. For commercial generator installation, TriStar will evaluate your property to assess which generator size is best.

Generators can also be controlled automatically or manually. Automatic electrical backup systems will, as the name implies, keep your electrical devices running even if the power goes out. You can program it to power certain sections or the entire building. Meanwhile, manual electrical backup systems give property managers some control over if and when they want to keep on the power during an outage.


Who can benefit from our commercial generator installation, maintenance, and troubleshooting services? If you operate a commercial property, you want a reliable commercial generator. We service the following industries:

  • Groceries
  • Warehouses
  • Data centers
  • Office buildings
  • Schools
  • Retail stores
  • Hospitals
  • Senior living centers
  • And more

Why Are Commercial Generators Essential to Businesses?

Businesses must continue operating as seamlessly as possible, even if a power outage happens. Without electricity, companies can lose data, inventory, and productivity. To put it simply, commercial generators help with the following:

    • Preserving data on computer systems
    • Keeping business up and running
    • Keeping produce from perishing, if it is a grocery or any business selling produce
