Install Schneider XW Pro (6848 Inverter/Charger) for an emergency back-up at home.
I have finished in 2020, but, Just found an installation photo.
I have add 2/3" Plywood on the wall to hold the inverter, it is so heavy (137lb),
And, prepared back-feed to main breaker panel for whole house power.
Inverter / Conduit Box / Gateway / SCP / Extra electric parts (wire / breaker / interlock / conduit / .....),
Total cost is around $5,000
