I am trying to figure out if and how I can achieve the same/similar setup as with a Redarc BCDC1225D or ctek D250SA (SE); i.e. I want to charge a service battery in the car with the alternator and a solar panel, potentially both providing power at the same time (solar panel on the roof while driving). Obviously, the starter and service battery should be disconnected when the engine is not running to avoid the starter battery from running flat.
I am looking at the SmartSolar MPPT 75/xx and the Orion-TR Smart DC-DC Charger. Using each standalone would not be a problem but how would I need to connect the two units and the battery together?
(Secondary question would be to install battery sensor and have battery sensitive charging).
The reason for trying to work with VE products is the Bluetooth capability which I consider very valuable and quite unique in this area.
