12 volt only solar setup?

Originally posted by StephenH Originally posted by offgrid You don't need to have a second connector to do that. If you run your solenoid output to the TV +12V pin on the Bargeman it would do the same thing. That is good advice for someone who is contemplating doing the job, but since it is done, I'm not going back and re-doing it just to run through the Bargman. Besides, I think I already stated that the Frontier's wire used for 12V power was not heavy enough for what Renogy specified. Running a dedicated wire ensures that I am not going to have issues with it as long as I own the Frontier.

Agreed. There is nothing wrong with the way you did it. I was just pointing out that having a second trailer connector, which might not appeal to some, is not a requirement for others contemplating a Li conversion. As I said when I referred the OP to your Li mod write up, that was the only item I would change.

Most trailer connector kits, including the popular one from etrailer, already include 30A capacity, which should be plenty for most folks. I wouldn't try to push more than that through a 7 way connector anyhow. Just get a DC DC converter that has an input current rating which doesn't exceed that.

If you wanted to use a TV high capacity alternator to charge at a higher rate than that then a second high ampacity connector would be needed. That is an interesting option to consider if you wanted to eliminate carrying a generator for recharging.

I agree. Multiple connectors become multiple failure modes, either caused by lack of human intervention corrosion, mechanical, or thermal stress.
