This is how I am planning in wiring my off grid tiny house on wheels (essentially a caravan) and just wanted to see if anyone can see any issues with it? Is the earth circuit correct? Photo attached.
I haven't drawn any of the AC side of of the installation for the purposes of this diagram but I'd like to add that in addition to the connections in this diagram, I will also have:
-All the earth's from my AC loads will connect back to my negative buss bar
-A large cable (same size as battery cable) joining my negative buss bar to the trailer chassis.
Another note - The reason I have run the MPPT positive cable through the other pole on my DC isolator is because when I switch that off I want everything to stop, including the charging of my batteries. I realise I can just turn the PV isolator switches off and achieve the same result, but I want it all to turn off with the flick of one switch.
Sorry for the long winded question and thank you in advance!
