In this first photo from a project in Taiwan they just laid out the items to get a feeling for how it all goes together and figure out what pieces they were missing. You can see more photos of the finished project here.
In this next one they actually connected everything together and fired it up to test it all out before installing.
In the pictures above I spot one of the Victron Lithium Smart batteries, a Multiplus inverter charger, a Color Control GX, several MPPT solar charge controllers and lots of circuit breakers. You can also see the Mk3-USB interface used for programming. This is a whole working system built on the bench. Not a bad idea if you have the time and space, its quite a complicated system as you can see. You can see more on their Instagram Page
This last project is even more elaborate. It was designed for the "Ultimate Camper Van" and the entire system was set up before the van was even purchased. This is a 48 Volt DC system and was completely assembled even before the vehicle was purchased. Here are a few screenshots:
This project is detailed in a couple of magazine articles: A Mad Scientist’s Take on the Ultimate Electrical System (Part 1) and A Mad Scientist’s Take on the Ultimate Electrical System (Part 2)
