ORION Tr-Smart Remote Input inactive

Guys, I‘m really fucked up now. It worked for a long time, anf all of a sudden the remote input turned inactive without a cause.


Voltages are ok, jumper is ok and plugged. Anyone experienced this?

Now guess what. After about 30min drive it ‚accepted‘ the jumper and it started to charge. No recognizable coincidence whatsoever.


I‘m clueless.

Today the same: remote input inactive and after 40min drive it started charging.


It never did that when I was using 12V at the H pin.

There is a coincidence:


When I first installed the Orion, it was March 2020, ambient temps around 10°C, the L-H jumper didn't work, 12V to H-Pin was my workaround.

A few weeks ago I was curious if the jumper would work, it did. Ambient temps well above 20°C.

Now, temps again 15°C and below, it took 30-40min drive to switch to active. Because it warmed up!


My guess is a cold soldering of the L-Pin on the PCB, or a hairline crack of the line on the PCB to the L-Pin. Proof: I put 12V to H and it turned active. I put ground to L and it stayed inactive.


Dunno if I'm right, but when I'm back from vacation I will tear everything apart anyways to swap the 90Ah GEL with 250Ah LiFePO4 anyways, and then I will dismantle the Orion and have a look.

Nope. Did check it several times, as the jumper cable and terminal screws as well.
