I am putting together the electrics for a camper van. I currently have the following items:
- Multiplus 12/1200/50
- SmartSolar 100/30 with a 350 Wp solar panel
- SOK 206 Ah Lithium Battery (Max charge current 50A, max discharge 100A)
I have two points that I need some help figuring out:
(1) I realized that the max theoretical charging current (shore power + full solar) would be 80A, exceeding the battery's charge current of 50A. Would this be a problem? I found that a Cerbo device can be used to limit the charge current to the battery. I feel like this a relatively advanced device for my simple system (and it adds to the costs as well). Would it be highly recommended to get one, or are there other options?
(2) I would also like to be able to charge via the (smart) alternator. Initially I thought I could use a cyrix-ct, but with the 120A rating this would not work with my battery, correct? (Even disregarding the fact that solar charging wile driving would even add more current). I am trying to figure out a solution that could charge my batteries without killing them, and prioritizes solar over alternator. I came across the Orion DC-DC charger, but because it does not connect with a Cerbo device I would not be able to prioritize solar, correct? Any other methods?
