Solar mppt controller, uses for "load" outputs

Due to the way Winnebago wired my coach, the chassis battery does not charge from shore power. My solar panels are wired parallel to that circuit. I bought a small 12vdc timer and have it set for 30 minutes every three days to use the "load" output trickle into the chassis battery.

The timer was less than $10 and I intend to use it when I finish my 12 vdc solar landscape lighting system to turn the lights on and off.
