I'll be wiring everything together soon. Looking for feedback on my wiring diagram. Where should I add in the battery monitor? I plan on tying the batteries, PD4045, and charge controller to the junction posts inside the trailer. Any issue with the location of my battery switch? My idea is that isolates the PD4045 but allows the MPPT to continue maintenance charging while in storage. My two chassis ground points are the battery negative and the AC ground buss bar from the PD4045. Correct?
I've drawn this after reading dozens of posts and articles but there is a chance I have confused something, so feedback is appreciated.
