Recently Retired, Building out Camper Van System and would like a sanity check

[RobertD]

Hello. New to the forum and new to Solar. I recently retired and am a month or so into outfitting a camper van. I've order most of my solar/electronic components and am working up wiring plan. I've seen a number of schematics which run all/most wiring through a set of bus bars. I don't fully understand how that works, but I've taken a stab at laying out my proposed system along those line and would love some more knowledgeable eyes to review and comment. The system is based on a number of Li Time components ( 2 x 280Ah batteries, 60A MPPT controller, Inverter/charger) and 750W (3 x 250W) Rich Solar panels. Very much appreciate anything you can offer. Thanks (& happy Thanksgiving)!! Rob

Are you going to add any disconnects?

Move your 12v lights and stuff to the bus bars too.

You'll need to math out the fuses and wire sizes, disconnects are advised for troubleshooting and maintenance. Start with MRBF fuses on the batteries and work from there.

Make sure your disconnects/breakers are rated for DC.

If you park anywhere with shading, parallel might be a better option for the panels. If not then series is the way to go.

Looks like a good start of a plan.

Possibly useful for you.

One approach is to run the chargers in through a blue sea power hub.

Just put it in where one of the fuse blocks is shown.

Always go through a fuse or breaker to your appliances and chargers vs attaching to the main bus bar.

Hi. Thanks. Yes, working on the wire gauges and breakers/fuses/disconnects. That will most likely be a follow-up post.

Awesome. Thanks! I will check out MRBF fuses for the batteries and moving 12v appliances to bus bars. Am working on other breakers/fuses/gauges/disconnects. A lot to come together.
