12V 30A DC-DC On-Board Battery Charger with MPPT Setup
This video demonstrates the process of connecting the Renogy 30 Amp DC DC MPPT Charger to a 12-volt starter battery, a 12-volt lithium house battery, and integrating 100 watts of solar charging. The charger follows a four-stage charging process for non-lithium batteries and remains in the boost stage for lithium batteries. It includes a battery temperature sensor, a smart alternator ignition wire, and ring terminal connectors. The setup involves connecting the negative terminals of the batteries and the solar input to the charger, and the positive terminals of the lithium house battery and starter battery to specific ports. The system allows for dual battery charging, prioritizing either solar or alternator charging, and can be optimized using additional accessories.
