Charging-Solar,Alternator,Converter/Charger

I just want to add that trying to recharge your battery bank from your vehicle alternator is NOT going to give very satisfying results especially if you have a true deep cycle battery bank. The vehicle charging system might be able to "prop up" the battery bank so that you can run an inverter for a household refrigerator, but that is about it.

If you are boondocking and run short on battery reserve (due to some type of failure in your solar charging) you best option is to hook your inverter directly to the vehicle battery with the shortest properly sized wire and then run your charger off of that.
