1. What is Watts Calculation?

The Watts calculation helps determine the appropriate size for a home generator by considering both the running watts (continuous power needed) and starting watts (extra power needed when appliances start up).

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Running Watts — Continuous power required to keep appliances running
• Starting Watts — Extra power needed for initial startup (typically 2-3x running watts for motors)

Explanation: This calculation ensures your generator can handle both the continuous load and the temporary surge when devices start up.

3. Importance of Proper Wattage Calculation

Details: Accurate wattage calculation prevents generator overload, ensures reliable operation during power outages, and helps select the most cost-effective generator size.

4. Using the Calculator

Tips: Enter the running watts and starting watts for your appliances. Many appliances list these values on their labels or in manuals.

5. Frequently Asked Questions (FAQ)

Q1: How do I find running and starting watts for my appliances?
A: Check appliance labels, manuals, or manufacturer websites. Many appliances list both values.

Q2: What's a typical starting watts multiplier?
A: For motor-driven appliances (like refrigerators), starting watts are typically 2-3 times the running watts.

Q3: Should I add a safety margin?
A: Yes, it's recommended to add 10-20% to your total calculated watts for safety and future expansion.

Q4: What happens if my generator is undersized?
A: An undersized generator may fail to start appliances, shut down from overload, or be damaged over time.

Q5: Can I run everything at once?
A: Consider staggering startup of high-wattage appliances to stay within your generator's capacity.
