How to Use the Industrial Generator Calculator
Configure Site Conditions
Start by entering your facility's Voltage (e.g., 480V), Altitude, and Max Temperature. This establishes the baseline for calculating environmental derating, which ensures your generator won't be undersized for local conditions.
Enter Electrical Loads
Add each major load (Conveyors, Pumps, Lighting). For Motors, specify the Horsepower (HP) and starting method (e.g., VFD or Soft Start). The calculator uses this to accurately determine the heavy surge current required to start them.
Review Sizing Logic
Check the Sizing Logic funnel in the results panel. It visualizes how your base load, starting surges, and environmental factors combine to determine the final recommended kW/kVA rating.
Estimate Fuel Needs
Use the Fuel Estimator to see approximate consumption for Diesel or Natural Gas. This helps in planning fuel storage for extended outages or prime power applications.
