My wall is made of drywall with light-weight aluminum framing. The structure of the house is welded steel.
I'm thinking about using nuts and bolts to mount my components to horizontal strips of 2mm thick steel.
My components:
MPPT 250/100 TR
Mutliplus 48/5000/70
50cm wide metal cabinet that houses CerboGX, Touch 50, busbars, some cables, etc.
On the floor, below these components, I'm going to place 4 Pylontech US3000 in their proprietary rack
