Simple? Electrical Setup (Novice)

[firsttracksbmax]

First and foremost, I’m a total electrical novice. The more that I read on here and elsewhere the more I get overwhelmed by the complexity of setup and the more I start questioning my simple(?) setup.

I’ve got an ‘03 eagle on an 2013 Tacoma that Im adding solar and DCDC charging to. The Eagle is currently equipped with the stock Surepower 1314 separator and buss bar next to it. I’ve got a single 100ah BB battery.

I’ve already installed 200w solar>30A MPPT>battery. It works, now I need to add the smart shunt, and install the DCDC charging, and here is where the confusion comes..

Most places I read everyone is raving about installing a 7622 separator. From my understanding, this would be more essential if I had multiple batteries or no DCDC charger? Do I need a 7622 if I have a 30A DCDC charger?

If I can just use the 30A DCDC, would this rough sketch setup work? Or must I be upgrading my Surepower 1314 and upgrade buss bar, etc. Recommendations highly appreciated. My electrical needs are minimal currently. Thanks in advance for my lack of knowledge.

For a simple one-direction charging system (where the truck battery cannot be charged from the camper battery and solar panels), with the dc to dc charger, you no longer need the battery isolator for charging the camper battery from the truck electrical system. The charger, when set up and installed properly, only draws current when the truck engine (and alternator) is running, so the isolator in series would be redundant.

Some people use an isolator or switch in parallel with the dc to dc charger to allow the truck to be charged from the camper battery and solar system. Most don’t do this, though, and I would suggest not doing this, initially at least, to keep thing simpler.
