You can add extra fields by selecting the add appliance button and scrolling thru the extensive list, or just type in your appliance or medical device. Most of the drop-down listings have the average loads filled in, so you need only add the estimated hours of use and number of days used per week.
Because some items are not used every day, the calculator automatically calculates the watt hours per day over the entire week. For example: if you only use your hair dryer three days a week, it will spread the calculated watt-hours over 7 days.
"More information" gives common appliances with the average loads and runtimes based on our experience, having designed over ten thousand off-grid systems.
