My question too, Devin.
A couple of years ago I was considering a Victron 100/30 to replace my Heliotrope that was acting up after I upgraded to AGM Coach batteries. As I recall, the Victron didn’t have the ports necessary for feeding the Aladdin, and I like easily seeing that solar condition on the Aladdin screen next to the other power ones. Like you, that was one reason I didn’t change controllers, that and the fact that the Heliotrope unexplainably stopped being a problem. If I bump up from one 100W to two 200W panels, I would then likely upgrade the controller.
As an aside, contrary to some belief, our HPV-30D controller is an MPPT model (Maximum Power Point Tracking).
