Looks good, all the wiring looks to be secured well and organized.


A few suggestions for improvements.

If the system has any fuses I would figure out some kind of mounting bracket to have spares there for a quick fix without having to go hunting for them. Also a flashlight mounted on the wall with a quick release of some type would be nice. Again so you don’t have to go hunt it up.

I would put the paperwork in a zip lock bag to protect it. And label the switches with a stick on label. And maybe a kill switch on the positive side of the battery.
