How Do I Determine My Power Needs?
Steps to calculate the right generator size for your equipment or jobsite.
Overview
Before selecting a generator, it's important to understand the total power your operation requires. This guide helps you calculate the correct load and choose the right ANA generator to match your demands.
Step 1: List Your Equipment and Estimate Load
- Identify all devices or tools to be powered (e.g., pumps, compressors, lights, welders).
- Gather running and startup wattage for each item.
- Add the total wattage to estimate your continuous load.
- Factor in startup or surge load for heavy-duty equipment.
Tip: Use nameplates or product manuals to find wattage requirements.
Step 2: Understand Your Load Type
What kind of usage will your generator support?- Steady Load: For operations with consistent power use (e.g., lighting banks).
- Variable Load: For jobsites or tools that power on and off during the day.
- Backup Load: For emergency power applications with intermittent use.
Each scenario affects the generator size, SmartLoad™ compatibility, and runtime needs.
