They recently stated they have trials with multiple customers. This ad was for multiple sales people in Chicago, East coast, West coast, and southern U.S. Hopefully in the next financials and conference call they will add some color to this situation as well as details on their fifth customer and maybe announce their residential storage customer's name.
