[RE-wrenches] Morningstar new battery backup , more comments and opinions

[Mac Lewis]

Hi Chris,

I think this would be a product mainly used in existing grid-tied
retrofits.  If there is an existing grid-tied only inverter, you could
route the DC conductors through this transfer switch first giving the
homeowner a grid-tied or off-grid option if the grid was down.  You'd still
need another battery based inverter with an AC transfer switch, critical
load panel etc.
