Can you link me to those patents then, because I didn't see them at the time. all I read was that they tested 4 types of batteries, and picked the best one, then wired them up. You had to buy the other equipment seperately to plug them in to your home solar. There was nothing of value in the patents at the time they released the Powerwall.
