Tips on Choosing the Right Generator Size for Your Commercial Space

 

Calculate the Full Load Capacity by Measurement

This is the most standard procedure used for determining the full load capacity in your commercial area. You can estimate the required capacity by taking the full-load current measurement during peak usage from the service panel. The generator size can be determined by adding the full load kilowatts (total ampere x supply voltage / 100) with the reserve capacity (full load kilowatts x 0.25). This calculation will give you enough power to support your commercial space based on the accurate calculation.

 

Check the Full Capacity by History

Some people don’t want to complicate things by calculating the power required. Simply look at the billing system for finding their maximum power usage. This monthly bill usually includes the peak demand in your busy days. You can analyze the power usage in your billing system and then add about 25 percent for the reserve capacity. This method is suitable for those who operate commercial spaces for 24 hours a day. If you have any equipment running for 24 hours a day, for example, refrigerators, AC, or freezers, you can consider this method.

 

Look at the Full Load Capacity with Extensive Motor Use

To do this calculation, you should find the starting current for the biggest motor inside your commercial space. You also need to add the total watts required by all of your motor loads or non-motor loads inside your commercial space. Don’t forget to add about 25 percent of the total watts for the surge or reserve capacity in your commercial building. This calculation can help you find the right generator size depending on your needs.

 

Check the Square Footage Measurement

This calculation is suitable for you who want to install a generator in your retail areas, such as restaurants, convenience stores, grocery stores, and any other commercial properties. You can simply calculate the generator size required by using this calculation. For retail applications, you can use 50 kilowatts + 10 watts every square foot. For other commercial applications, you can use 50 kilowatts + 5 watts for every square foot. Although different commercial properties may have their requirements, you can still use this calculation for helping you find the right generator size for your needs.

 

Look at the Type of Business you Have

This is another important thing to consider. You also need to take a look at your business type before you decide to select the right generator size for your commercial properties. If you have a tech-related company, you may need to use a large size generator. Tech companies tend to use a lot of energy for supporting their daily activities. Therefore, they usually want to use a large generator in their commercial spaces. Different business types may require different generators with different capacities, so you have to compare all available commercial generators before you decide to buy the best one for yourself.
