*'''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|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|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|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
