Of course this could be a great collaboration. SMA whilst back on track, and by some measures still the leading solar inverter manufacturer in the world, face stiff and growing competition from Chinese giants Huawei and Sungrow in their core solar market. SMA are already well established in storage too, so they'd be a great partner for VW.

Whether that works both ways, should the talks advance, is to be seen. Clearly VW have a great deal of work to do to rebuild their brand and reputation after dieselgate. I'm still not convinced that auto-manufacturers in general really understand the pace of change in automotive and energy storage markets, despite the daily news and announcements, and some big names I fear will miss the boat!
