Yeti 4000 Escape Driveable Kit - Alternator Wiring
I am trying to figure out the best method for wiring for both alternator and solar charging. The manual shows using the 10A for the alternator further in the book, but that seems too slow. It also shows a wiring diagram for using the combiner. Is it best to get the combiner? Do I need to put a shunt or anything coming off the battery? There is not much detail on this, so any advice would be appreciated.

Hello @Gilster10 ,
You can use either the 8mm or the HPP+ (low and high voltage respectively) to do alternator or solar. The best option for vehicle charging is the HPP+ as it can take up to 40A as opposed to the 10A from the 8mm. If your solar is under 300W, use the 8mm port for your solar and the HPP+ for your alternator option. If you are doing more than that, you will need to wire solar and alternator charging to have an HPP+ connection then unplug one and swap the other one out when you park or start driving. There was originally a plan to use the 3 in 1 Parallel combiner to allow both to be plugged in but there were issues as most solar is around 20-30V (unless in series, then more) where as the vehicle will generally peak at 13-15V and the 3 in 1 combiner needs both sources within 5V.

But I could consider doing a 12v solar charge controller to use the parallel combiner, correct? Also, can you hook up HPP+ to regular HPP?

Hello @Gilster10 ,
That would not work as the Yeti 4000 already has a charge controller. At this time the 3 in 1 Parallel combiner will not work as the voltages are too far out of the 5V range.
