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.
