FAQ

What are the benefits of using commercial generators? + -

Commercial generators are designed to provide a reliable power source in case of power outages. They are built to handle heavy loads and can power essential equipment in commercial settings like farms, construction sites, or retail stores. They also come with features like automatic start and fuel efficiency that make them convenient and cost-effective.

How do I choose the right commercial generator for my needs? + -

Choosing the right commercial generator depends on your specific power needs. Consider the wattage requirements of the equipment you need to power during an outage. Also, consider the type of fuel you prefer (diesel, natural gas, or propane), as this can affect operating costs and maintenance requirements.

What is the difference between portable and standby commercial generators? + -

Portable generators are designed for temporary use and can be moved around easily. They require manual setup and operation. Standby generators, on the other hand, are permanently installed and automatically start when they detect a power outage. They can provide uninterrupted power for longer periods.

How often should I perform maintenance on my commercial generator? + -

Regular maintenance is crucial for the longevity and performance of your commercial generator. It's recommended to check your generator weekly for any visible issues and run it at least once a month to ensure it's working properly. Professional servicing should be done at least once a year or as recommended by the manufacturer.

Can I install a commercial generator myself? + -

While it's possible to install smaller portable generators yourself, larger standby generators should be installed by professionals due to their complexity and the need for proper safety measures. Improper installation can lead to performance issues and may void the warranty.
