Hello all,
After many months of learning, I have decided to take a stab at designing the electrical power system for our off-grid van. I have a diagram of the system attached to this post below (Also hosted on imgur for high-res).
I have labeled everything except for fuse and wire sizes as I'd like to get some feedback on the general connections before I get into wire/fuse sizing.
A few extra questions/concerns I have:
- I have seen similar systems with 2 POS and 2 NEG cables feeding into the MultiPlus after the Class-T fuse following the positive bus bar. I have also seen systems with just 1 set of cables. For this system, which one would suffice?
- I have seen similar systems with 150A fuses coming directly out of each battery before they join at the positive bus bar. Would I benefit from this or is a 500A fuse sufficient coming out of a parallel battery arrangement.
- What type of solar panel arrangement would you recommend for this system (S/P/S-P)? I mislabeled the diagram (I named it Parallel but it's wired in Series)
This has been an amazing experience immersing myself into an area I knew nothing about just a year ago! This community has been awesome, can't wait to hear back!
Thanks,
Manny
