Standby generators are a lifesaver during power outages caused by breakdowns, storms, and other factors. Most malls, hospitals, banks and businesses require an uninterrupted power supply around the clock.
The key difference between an ordinary generator and a standby generator is that the standby turns on automatically.
How Standby Generators Work
A standby generator works like a normal generator, converting the internal combustion’s mechanical energy engine into electrical energy with an alternator. These standby generators come in different shapes and sizes. They can run on different fuel types, such as diesel, gasoline, and propane.
The main difference is that standby generators consist of an automatic transfer switch to function automatically.
Automatic Transfer Switch
An automatic transfer switch is at the core of your backup system. It senses and disconnects from your power grid and transfers the load to connect the generator to provide emergency power automatically in the event of an outage. Newer models also include power management capabilities for high-current loads and appliances.
This process takes up to three seconds; provided that your generator has sufficient fuel supply and is functioning properly. When the power returns, the automatic switch also turns off the generator and transfers the load back to the utility source.
Power Management System
Facilities have different high-voltage devices, such as heaters, air conditioners, microwaves, electric dryers, etc. If any of these devices were on at the outage, the standby generator might not have the power capacity to manage the complete load depending on sizing.
The power management option ensures that high-voltage devices only run when there is sufficient power. As a result, lights, fans, and other low-voltage devices will run before the high-voltage ones. With power management systems, loads get their share of power according to priority during an outage. For instance, a hospital would prioritize surgical and life support equipment and emergency lighting over air-conditioning and other ancillary systems.
The advantages of a power management system are enhanced fuel-efficiency and protection of loads at lower voltages.
Generator Controller
A generator controller handles all the functions of a standby generator from start-up to shut down. It also monitors the performance of the generator. If there is a problem, the controller indicates it so technicians can fix it in time. When the power returns, the controller cuts the generator’s supply and lets it run for about a minute before shutting it down. The purpose of doing so is to let the engine run in a cool-down cycle in which there is no load connected.
Why Every Business Needs Standby Generators？
Here are six reasons why every business needs a standby generator:
1. Guaranteed Electricity
24/7 electricity is essential for manufacturing plants and medical facilities. Having a standby generator gives peace of mind that all critical equipment will continue running during outages.
2. Keep Stock Safe
Many businesses have perishable stock that requires fixed temperature and pressure conditions. Backup generators can keep stock such as groceries and medical supplies safe in an outage.
3. Protection from Weather
Humidity, high-temperatures, and freezing conditions due to power outages can also damage equipment.
4. Business Reputation
Uninterrupted power supply ensures you’re always open to keep your business running. This benefit can also give you an edge over your competitors.
5. Saving Money
Many commercial businesses purchase standby generators so they continue operations without losing contact with customers.
6. Ability to Switch
The ability to switch to emergency power systems offers an alternative energy plan for business. They can use this to lower their bills during peak hours. In some remote areas where power is not consistent or is supplied by another means like solar, having a secondary power source can be critical.
Final Thoughts on Standby Generators
A standby generator makes good sense for any business, especially in those areas where power outages occur regularly.
