Confused about what size generator you need? Use our free Generator Power Calculator to quickly determine the ideal wattage for your home, RV, or job site. Avoid underpowering or overspending by accurately estimating your running and starting watt requirements.
Formula:
The required generator power is calculated by summing the total continuous running watts of all your appliances and adding the highest starting/surge watts of any single motor-driven appliance.
Formula: `Required Generator Power (Watts) = Total Running Watts + Largest Starting Watts`
Where:
- Total Running Watts: The continuous power (watts) consumed by all appliances operating simultaneously.
- Largest Starting Watts: The momentary peak power (watts) required by the largest motor-driven appliance (e.g., refrigerator, well pump, air conditioner) to start up.
