[RE-wrenches] Storage Batteries for dwellings -Canadian Code

[Dan Fink]

I wonder how this code will apply to the new SonnenBatterie system, which
uses a high-voltage lithium battery bank adapted to an Outback Radian
integrated into the cabinet. I'm guessing it will be the same...the
user-accessible side will be 48VDC.
