Choosing the Right Generator Size for Your Facility
How to calculate the correct generator capacity for your power needs.
Selecting the correct generator size is critical for efficiency and cost-effectiveness. Follow these steps:
- List all loads: Make a list of all equipment and appliances that need backup power.
- Calculate starting and running watts: Some loads have high starting currents; account for both.
- Consider future expansion: Plan for additional loads that may be added later.
- Choose a margin: It's wise to oversize by 20-30% to handle unexpected loads.
- Consult a professional: Work with an experienced dealer to ensure you select the right model.
