if the orion is in current limitation, i.e. the load at the output is so high that it has to be limited, then it cannot be switched on via the remote. The LED turns on, but the output does not go on. You have to switch the remote first and then switch on the load.

when the orion is in the current limit, it makes a very unpleasant loud noise.
i would like to use the orion to charge a battery, i just sketched it very simply.
I think you have two connectors on the left, one marked H and one marked L. These should be bridged, with and optional switch in there.
There are other wiring options, but the one I described seems most appropriate.
Make sure you set the right mode for the battery you are charging.
You are using an isolated DC2DC charger wired like as a non isolated one, which it was not designed for. I suspect that may potentially contribute to some of your problems in addition to what kevgermany mentioned. Below is the ideal setup for your Orion.
got an new Orion (older version) from my victron dealer, now it works as expecte.
