In this step you need to list all your AC (Alternating Current) and DC (Direct Current) loads.

Make a list of the appliances and/or loads you are going to run from your PV system. Find out how much power each item consumes while operating. Most appliances have a label on the back which lists the wattage. If an appliance is rated in amps, multiply amps by operating voltage (120/240) to determine watts. Specification sheets, local appliance dealers, and the product manufacturers are other sources of information. We have provided the list of typical, common devices which you can use as a guide. You can open the list and select the load by clicking "Select Load" button. And elsewise you can use "Add Load" button to add as much custom AC or DC load fields as you need.
