[RE-wrenches] Energy Storage and Working Spaces for Other Equipment

[Jason Szumlanski]

100kWh/day of consumption is pretty typical during hurricane season in
Florida for the type of client that can afford battery backup and enough PV
to keep the frozen margarita blender going. My clients don't want to change
their lifestyle. After all, they don't have to with a whole house
generator. Why would they with solar/battery. Even 60kWh is a tough ask to
get through the night with 85F nightime ambient and 95% humidity in August.

Telling a grid-tied client that wants whole home backup with solar/ battery
that they still need a backup generator is a non-starter. So we need really
big batteries here (and a lot of roof space). Some of the new battery
players just don't get that. I won't name names, but 40kWh or less max
parallel capacity just isn't marketable here.
