With the need to power two separate tasks: trickle charging two starter batteries and (re)charging a house battery that is constantly in use, operating a 4.2W 12V dash camera, including at night when that house battery is not being replenished by the sun, the notion of using two separate solar panels for each task, with their own controller, or one solar panel and system comes to bear for me.
It is my newbie understanding in a one solar panel setup that the solar panel and its controller will likely energize either the starter batteries (plural: I have two from the factory connected in parallel) or the house battery, and that the battery which is being replenished by the sun will then, vis a vis a DC to DC charger, charge the other battery system.
From what in my ignorance I can see, it seems that systems for sale for the most part charge the starter batteries, which in turn charge the house battery, vis a vis a DC to DC charger, but only when the engine is cranked, not my desired goal. I wish both battery systems to get replenished from the sun when the vehcile is parked.
How do I set this up? Which battery, the starter battery pair, or house battery best be direct connected to solar panel, and and what DC to DC charger might allow the other battery not directly connected via a charge contoller to the solar panel, to be replenished from the battery directly connected through a charge controlled to the solar panel?
Thank you.
