Electrical Plan Check (For Ground Up Build)

Have been looking at combined DC to DC chargers with MPPT input and came across one from Renogy, https://www.renogy.com/dcc30s-12v-30...ger-with-mppt/. Comes in both a 30 amp and 50 amp versions. Anyone here using one?

I saw this as well and Scalf77 posted about it on another thread (Link). From everything I have seen from Scalf77 I would say his opinion holds a lot of weight as he is the expert. My biggest hesitancy with it and what led me away from it was the lack of reviews, and the mixed reviews of Renogy in general. Seems like a cool product with some pretty neat features, but for me it just didn't seem like the right thing. That's also just one opinion with very limited actual experience with any of these products, so I would take that with a grain of salt.

In my LiFePO4 setup I abandoned my SurePower isolator and replaced it with a Renogy 40a DC-DC charger. It does everything it's supposed to and has operated flawlessly although it's not overly laden with features. Set up was a little confusing (note though since buying mine, Renogy updated its user manual for this charger so this is no longer an issue). Since installing this charger, there have been other DC-DC chargers that have come to market. Had I to do it over again I would seriously consider DC-DC chargers with MPPT input and and compatible (eg bluetooth) with other equipment, like the Victron, or a charger with adjustable output, like the KISAE.
