HI Dan,

Do you have any links on info on the battery?

A quick search didn’t find anything.

Yea I know given SMA time, I’ll be long retired when it comes out but still.

Except the doctors get their CEUs for free to learn how to diagnose and prescribe those meds, we have to pay all travel, lodging and workshop expenses to learn how to responsibly sell, install and retrofit PV systems for grid tie battery backup.
