DC Electrical Distribution

I built a new DC distribution panel to replace the old temporary stuff I removed. Shown here are various photos during the wiring and installation inside the panel.
The primary purpose of this panel is to distribute the power from the buck converters that take the 48 volt DC power and output 12 volts. They can’t be tied together so there are four separate “branches” of power.
The 12 volt systems power water pumps, fans, lights, and heaters that are “house” related.
In the case of an inoperable 48 volt system, the power contactors in the upper left corner of the cabinet can utilize power from the starting batteries.
