I thought this sounded to easy. So the best way to do this would be the sterling dc to dc charger. I would have to go look at website, but doesn't this replace the built in regulator in the alternator to get the higher voltage?
I am using the SBMS120 that has a capacity of 75amps for each input. I was planning to use the 40 amp version of the relay, so this shouldn't overload anything? I am a woodworker not an electrician so not trying to argue, trying to learn.
I was planning to run wire directly from the relay into the second input on the solar control!er. The controller that I will be using will perform all the cell balancing,voltage etc. It sounds to easy doesn't it? If you see any problems with this plan let me know.
I am in the beginning stages of planning out a lifep04 system, using the electrodacus controller. I to am wanting to have the ability to charge from the alternator. I found that Mastervolt has a current limited relay. Here is a link Mastervolt Charge Mate Pro 40 - Electronics...
