This in the context of a 12V nominal travel trailer system I am building, the key components are
3.5 Remote on-off
The left terminal is connected to the internal 3,3V supply, with a resistor in series for short circuit protection.
The right terminal (marked as + or marked as H) will switch the controller on if >3V is applied, and will switch the controller off if <2V is applied or if the terminal is left free floating.
The recommended use of the remote on-off is:
a. A switch wired between the left and right terminal
b. A switch wired between battery plus and the right terminal.
c. A switch between the right terminal and the charge disconnect terminal of a VE.Bus BMS
5. Specifications, 150V models
Self consumption: Less than 35mA @ 12V / 20mA @ 48V

Questions ....
- Has anyone here rigged a switch per 3.5 a. or b. above to serve as an "on-off" switch for their SmartSolar controller?
- If yes, when the controller is turned "off" using that switch, does the controller continue to draw the small "self consumption" current or does the controller draw NO (zero) current from the battery?
- Is it correct that this switching capability can be safely used to turn "off" charging from the PV array without first disconnecting the PV array from the controller inputs?
