Validate final setup (solar, batteries, inverter)

I have 4 T-125's wired in series and parallel on my trailer tongue. I have the solar controller sitting in the storage compartment adjacent (at max 3' wiring distance), and I was planning to put my Kisae 2000w inverter there as well.
Here's what I'm thinking for my wiring:

1 gauge wiring between the batteries in series & parallel (1' length for series, 2' for parallel runs), then 2' of 1 gauge to a set of power posts near the exit from the battery box. From there 3' of 1 gauge to the storage compartment and another set of posts, where I'd hook up the inverter and solar controller.

Total wire run of 1 gauge from the batteries to the inverter would be max 6 feet - 1 foot from inverter to post, 3 feet to next post, then 2 feet to battery leads. Solar would be same, but 2 gage, leads can't take 1 gauge. Solar is collecting 500 watts from 4 12v panels.



Comments or suggestions?

  • That wire between the batteries and the inverter is too small. I've got 2/0 for a two foot run.

    You can get gauge adapters so you could use the 1 gauge with the solar controller.
  • Your inverter wiring is likely to be too small to run high-amperage draw stuff like MW and coffee makers. Your inverter manual should state at least 1/0 and more likely 4/0.
