Estimate the total generator load in watts by combining running wattage of appliances, surge allowance for motor starting, demand diversity, and a recommended safety margin.

Estimate the recommended generator size in kilowatts for a whole-house backup system based on home size, HVAC load, electric appliance count, desired backup coverage, and startup surge allowance.

Estimate the generator energy capacity needed in kWh based on total running load, surge factor, runtime, and desired reserve margin.

Estimate the recommended generator size in watts for your home based on running load, starting surge, backup duration, and a reserve margin for future or unexpected loads.

Estimate the generator wattage needed by adding the running watts of your appliances, accounting for additional startup surge, and applying a safety margin for reliable operation.

Estimate the generator size you need in running watts based on the total running wattage of your appliances, the largest motor startup surge, desired reserve capacity, fuel type efficiency, and altitude adjustment.

Estimate the recommended generator size in running watts by totaling appliance loads, startup surge, and a safety margin. Use this to size a portable or standby generator for home, jobsite, or RV power needs.

Estimate the recommended generator capacity in watts based on the number of essential appliances, their average running wattage, startup surge, and desired backup hours.

Estimate the recommended generator size in kilowatts based on total running load, largest motor starting surge, desired load headroom, fuel type derating, and site altitude.

Estimate the recommended generator size in kilowatts based on total running wattage, starting surge wattage, desired safety margin, and power factor.
