Van #2 2021 EXT
Hi @van_dammitDammit here, just requesting some kind feedback on my wiring diagram set up before I re-re-finalize my decisions
Planning on building a "simple" camper van, not a live-in /full-timer van.
The electrical setup location is behind the Driver's side in the back, over the wheel well.
- 2021 RAM Promaster 136WB
- No built in stove, AC, or toilet
- No large central water tank, just a 6 gallon under the kitchen galley and a separate 2.5 gallon in the rear fo a shower (2 x H2O pumps)
- mostly using 14-2 and 12-2 awg for my 12v devices
- wanted to save $ so my wire choices may seem odd but I tried to go larger ie. I just bought 2/0 and 4 awg wires
- still not sure what solar setup I am getting between 200W-400W of solar
- already did my pre-wiring for my 12v and 120v wires
Any tips and advice are welcome, first timer who is 3 months into the build...
For a 1st timer - good start (ya gotta start with something) 👍
Good comments by @Dekkars 👍
In General; Electrical is designed from the intended loads (now & future added loads) and worked back to the battery. Once the battery is “picked” then you figure out how to charge it.
The more “we” understand what you are trying to accomplish the better advise we can give you. The more defined your loads the higher resolution your design can be. As an example of “defined” you have shown a 2000W inverter, & although I can assume what “animal” that is without manufacturer specifications like peak Watts or peak amps I assume a 2000W inverter will peak @ 4000W (I have an unused 3000W that peaks @ 6000W or so says the manufacturer).
Sounds like you have prewired; where that might work out fine, it is best to finalize your electrical design before wiring.
Here are my point format comments;
No Shore Power?
2 pumps (for 50 seconds of running & 120seconds of running til empty @ full 3gal/minute) “need more info”?
How are you cooking - microwave only?
Fuses vs Breakers (maybe in some locations)
2 post battery terminal fuse holder?
Need for bus bars (2 post battery terminal fuse & negative shunt)?
If you go “breakers” get good quality ones.
Make your DC to the Inverter as close (short) as possible.
If you are going to add “Shore Power” then a “Power Center” similar to what @Dekkars referenced would be a good investment; AC Panel / DC Panel / Converter / Charger all in one box @ $200 to $400.
