Skip to content This troubleshooting guide and checklist is designed to help you identify and resolve common issues with your Orion TR-Smart DC-DC Charger. Whether you're off-grid, on the road, or running a marine power system, this walks you through the same steps we use for support tickets.
If you purchased your Orion TR-Smart from shop.explorist.life, ticket support is free — reach out at shop.explorist.life/support and we'll walk through it with you. Didn't buy from us and still need support? Check out our Pro Support Membership to get expert support from our team.
If you are trying to use this guide to self-solve your problems, here is an outline of things to look for. The following questions/answers should be used in conjunction with the guide above.
Are any camper lights/fans/loads working?
Lights/fans/etc indicate that the battery is 'on' and providing power.
Are any other Victron components functioning?
If other components in the electrical system are 'on', this is another indicator that the rest of the system may be properly functioning.
Confirm master battery switch is 'on'.
The Orion will not turn on if the master battery switch is 'off'.
Ensure your vehicle is on and running.
The Orion cannot charge unless the engine is running.
Ensure your house battery bank is not 'full' (either 90+% battery or above 13.5V is considered full).
A full battery will not charge.
Note any lights on the Orion.
A lack of LED lights on the front of the unit while the unit has appropriate voltage at the input/output terminals may be indicative of a faulty unit.
Confirm that the remote wire on the Orion is in place.
The jumper wire must be in place for the Orion to function.
Ensure solar charging is not overriding DC-DC charging by turning the solar isolator off.
If solar is actively charging, DC-DC charging 'may' not turn on immediately due to this secondary charging source.
Ensure shore charging is not overriding DC-DC charging by disconnecting from shore.
If shore is actively charging, DC-DC charging 'may' not turn on immediately due to this secondary charging source.
Follow the 'Step 3' programming guide in your troubleshooting workbook above and ensure proper settings.
Ensure proper workmanship.
Check for errors within the VictronConnect app.
Errors are typically accompanied by a 'show more info' button with additional info.
Verify output voltage of the Orion.
Output voltage of the Orion should be within 10% of the house battery voltage — if not, investigate why.
Verify input voltage of the Orion.
Input voltage of the Orion should be within 10% of the starter battery voltage — if not, investigate why.
