Battery charger upgrade and purpose of solinoid

I'm looking to upgrade my current, factory battery charger in my truck camper to something with a higher amperage.

As I understand it, the current charger converts AC to DC when I plug in and only trickle charges the battery at a couple amps. That can take days if not weeks to charge a 50% discharged battery. And the truck alternator charges it when the engine is running, but that too is a very low amps.

I'd like to upgrade to something faster for AC charging, but also for DC charging off my alternator if possible. Is there such a thing?

Also, can someone please explain what a solinoid is supposed to do? Apparently, my truck doesn't have one.

Thanks
Raz
  • Converter
    Truck alternator

    Two absolutely different systems that must be discussed separately. First of all for the truck to speed alternator charging a new, separate socket and plug must be installed a d new, larger wireIinstalled from the git-go. Are you ready to tackle that?
  • I don't know about truck campers, but if the battery charging circuits are similar to other RV types, there are plenty of alternatives. One limitation might be available space.

    The solenoid is basically a high current relay. Its function in my MH is to connect the house battery to the chassis battery when the ignition is turned on. That way the house battery gets charged by the alternator. I'm surprised this isn't standard in a truck camper.
  • Tell us the brand and model of converter you have now.

    A solenoid is a powered on-off switch. It can be normally open or normally closed although normally open is commonly used for RV applications.

    Whether or not your camper battery charges from the truck depends on how the truck is wired. You haven't even told us what you have.
