- Load: The make and model or type of load.
- Quantity: The number of of that particular load.
- Watts: The power rating in watts for the load.
- Total watts = quantity × watts
- Duty cycle = Rated or estimated duty cycle for the load. If the load has no duty cycle a value of 0 should be used. A load with a duty cycle of 20% would be inputted as .2
- Surge factor = Rated or estimated duty cycle for the load. If the load does not have a surge requirement a value of 1 should be used. Common values are between 3-5.
- Power factor = Rated or estimated power factor for the load.
- Volt-amperes (VA) = Total watts ÷ Power factor
- Hours per day: The maximum number of hours the load(s) will be operated per day. If the load has a duty cycle 24 hours should be used.
- Days per week: The maximum number of days the load(s) will be operated per week.
- Average daily AC watt-hours = Total watts × Duty cycle ÷ Inverter efficiency × Hours per day × Days per week ÷ 7 days
- Total average daily AC watt-hours = sum of Average daily AC watt-hours for all loads
- Total VA = sum of volt-amperes (VA)
- Total VA with surge watts = sum of Surge watts for all loads + Total VA
