Hi all,
I have a problem with my Orion XS 12/12-50A, which previously worked flawlessly. Recently, it has stopped functioning properly, and I’m seeing very strange behavior:
- The Input Voltage shown in VictronConnect always equals the configured “Input Voltage Lock-out” setting.
- If I set the lock-out to 12.5 V, it shows 12.5 V as input voltage. If I change it to 10.0 V, it immediately updates the input voltage display to 10.0 V — even though the actual system voltage is a stable 13.8 V, measured directly with a multimeter.
Measuring between IN+ and Orion GND gives the lock-out value. But between IN+ and chassis ground, I get the correct system voltage (13.8 V).
This suggests the Orion is either not referencing real ground correctly or simply not measuring actual input voltage anymore.
- The charging current never exceeds 2–5 A.
- I performed a full power reset (both input and output disconnected) and checked all cables — nothing changed.
- The unit was working fine earlier, and I suspect this started after a firmware update, but I can’t be completely sure.
Has anyone else seen this behavior?
Is there any way to roll back to a previous firmware version for testing?
Thanks in advance for any insight or confirmation — I’d like to avoid replacing the unit if this can be fixed by firmware.
EDIT: The current firmware version on the device is v1.12.
Best regards,
Antti
