Key Considerations When Buying a Standby Generator – Part 3

Part 3 will discuss Transfer Switches, Accessories, Equipment Maintenance, and Warranty.

7) Transfer Switches

Emergency standby systems are usually equipped with automatic transfer switches. Manual transfer switches are available for certain systems, but downgrading to this won’t save much money. Your electrician will determine the transfer switch’s size (amperage rating) and its location. They will be guided by whether the standby generator will need to power the entire facility or only emergency loads. 

For systems intended to power the entire building, it may be required for the transfer to have a service entrance rating incorporating a utility disconnect capability inside the . Transfer switch features for commercial and industrial applications include closed transition, bypass isolation, and programmed transition.

8) Accessories

A standby generator’s accessory options will depend on its type. Generators built for residential or light commercial systems usually provide an optional remote annunciator panel located indoors that indicates generator status. Remote monitoring and cold weather kits are also commonly offered. Industrial systems come with many more options, which involve communication, enclosures and their lighting, load centers, alternator strip heaters, and more.

9) Equipment Maintenance

Similar to cars, standby generators require proper maintenance to make sure they function as expected in the event of a power outage. Unfortunately, the tendency is to neglect generator maintenance for long periods. Lack of maintenance will cut service life, reduce reliability, and make equipment failure more likely at critical times. In addition, regular maintenance for a standby generator is required to keep its warranty valid.

10) Warranty

Depending on the type of generator, its warranty duration will range from one year to five years. While residential generators have standard two to five-year warranties, an industrial generator may have a standard one or two-year warranty with options for upgrades. It would be wise to have a solid understanding of the warranty duration and coverage of the standby generator you have installed. In addition, request information regarding options for increased coverage as they may be suitable for your needs.
