I'd be very cautious about getting too cosy with any of these battery companies, it seems their only aim is to get bought. Sonnen was acquired by Shell Oil, Pika by Generac. I'm a generac dealer so I am exploring what their intentions are. I doubt Shell will be gung-ho to continue to support solar, so where does that leave my Sonnen customers? Make sure your customers are aware you don't know where this is going and whether any of these guys will stay the course. Companies like trojan and Outback are going to be around, but Fortress? Unlikely.
