Orion tr smart 12/12 - 30 dc to dc shows wrong input voltage.
The input voltage is over 14v, but the app shows only 12.6v
What can be the problem?
Mine shows the same problem. After I used it without any issues for 3 years.
Input voltage 12,5 (no change if engine is running or not) . Starter battery and input at the Orion measured 14 V when engine is running. And: It DOESN’T CHARGE my battery.
13 V measured at starter battery and Orion input when engine is turned off but Orion still shows 12,5V in the Victron App.
What is the reason and how can I solve it?
I saw that error a few times, the device is defective.
Try to disconnect it completely for a few minutes and reconnect it.
If that doesn’t help contact your seller/installer/distributor.
Mine shows the same problem too. 12.5V is reported irrespective of vehicle volts from the alternator.
It took 30 days before mine locked out. But is was fixed by disconnecting both batteries.
I’m an electronics professional. I suspect the A/D converter measuring the vehicle supply gets into a ‘latched-up’ state, where a semiconductor junction has been upset by a transient voltage. This places the semiconductor junction into a fault state untill its power is removed. A lack of imunity to transients would normally be detected during CE compliance testing… but its quite difficult to test systems like the Orion-TR with two isolated sections. I would have designed the TR with a high value reisistor (1Mohm?) between the two sections to stop a dc potensial maybe developing across the 2 isolated sections (Victron didnt). lt would be interesting to view the Victron schematic to see if completely seperate A/D convertors are used for each side of the isolation, and thier use of high frequency capacitors to handle the nano-second rise-times of electrostatic dischages that could attack either side of the TR, in the real world. If it happens againn, I will probably connect the grounds of both sides together, giving a non-isolated system.
