Small DC distribution setup

Westend, that is a really impressive setup and looks well thought out. I hate sounding stupid but, where did you get the buss boxes or are they standard "J" boxes?

12 V distribution panel with three master disconnect switches. The three switches allow for battery bank switching for the converter, the inverter, and the solar controller.



The back of the panel is where all the connections are made with 4 AWG cable to the switches.



Below this distro panel are three power bus boxes, one (+) phase for each battery bank (two total)and one (-) phase bus for both. The device fusing is done in the bus boxes.





You can see the AGM bank in the above pic, 100AH total between the three. I also have a bank of two 6V GC2 golf cart batteries. The 6V's are 6' from the distro panel, inside in a vented box. I used 1/0 AWG for that 6'. The 1/0 is in 2" ABS pipe underneath the floor.

Thanks for the reply Robert, nice looking setup. I've been looking at the Blue Sea stuff, and it does look good. Differently planning on everything being on it's own fuse, plus a fused main bus. I've been debating about using a battery disconnect switch because I never really disconnect the batteries unless there is a problem, I use the solar as a maintainer.

I do appreciate the info and pictures. I find it's often easier the check out what others have done than reinventing the wheel every time I do something.

Thanks

In our camper, I'm using the stock setup. However, I have a solar setup at home for running portions of my house off the grid.

Most of the components I'm using are found in the marine industry. I particularly like products made by Blue Sea. Very nice high amperage switches, fuses, and well made power distribution panels.

I'd suggest having the inverter on its own separate fuse. I'm using a couple of 1800W Xantrex inverters, and each have their own disconnect switch, and a Class-T type fuse.

I have a separate DC power distribution setup for all the low current 12V items. It too has an isolation switch. Makes working on the system safe.

The power switches are Blue Sea P/N 6006. West Marine has them in stock, but I bought mine online.

The power distribution block I'm using for this project is a 24 position IOTA brand. Each connection has a separate fuse, and an indicator LED if the fuse fails. Here's a pic of the distribution block and the isolation switch being installed:



Here's what the Class-T fuse holders look like:



Here's a smaller distribution block I put on my golf cart, also made by Blue Sea:



Good luck on your project!
