Re: PHOCOS solar charger experiences?
I took a look at the documentation; while their literature says "positive grounding possible" and the manual refers to a positive chassis ground, if you are only connecting it to your solar panel and batteries, "ground" won't be an issue.
Assuming you won't need or use their load-disconnect feature, just make sure your panels + and - go directly to the controller (not tied to either battery terminal. Incidentally, this is exactly how my Blue Sky SB3024iL is installed, without any positive/negative ground restrictions: for current metering purposes, it too requires that the solar panel negative not be connected directly to battery negative).
I would leave the ship's loads on battery negative "ground", ignore the low-voltage-disconnect output, and be happy.
