It is crafted by combining 2-6 Energy Sensor Location Cards in a Crafting Table. These cards must have the coordinates of the Energy Units you want to display, attained by right-clicking an Energy Sensor Kit onto a BatBox, etc. (it will not work if you cheat the item in from NEI). When the Energy Array Location Card is put into an Industrial Information Panel, it will display information from each Energy Storage Unit you chose.
Above recipe can be made with 2-6 Energy Sensor Locations Cards.
