How the Daily Energy Load Calculator works
Enter each appliance's watts and its hours of use per day in the same order. Daily Wh = sum of watts × hours. This is the load figure you need before sizing solar panels, batteries, or a generator. Appliances with motors cycle on and off, so use an average draw. Example: with the default values, daily energy comes to 3.06 kWh.
