MPPT Load output disabled on MPPT being disabled?

Well, the title already describes it. Is the load output of a 75/10 being disabled when the entire MPPT is being disabled?

In particular:

  • The load output will feed a trickle charger hooked up to the main battery to maintain it.
  • Not to kill the trickle charger while cranking the engine, I want to switch it off.
  • Therefore, I want to switch off the MPPT using the RX port and ignition signal.

Not sure which trickle charger, but a brief drop in voltage at engine start shouldn't kill it, mine has survived being permanently on for nearly a year now.

Off should mean off for the MPPT.

A Votronic 3065. The voltage drop would happen on the output side, so irrelevant from my standpoint.

But, would MPPT off mean MPPT Load output off as well? If so, I doesn't matter how the Votronic behaves ..
