7. Troubleshooting

In this section:

Consult this chapter in case of unexpected behaviour or if you suspect a product fault.

The correct troubleshooting and support process is to first consult the common issues as described in this chapter.

If you experience problems with VictronConnect, first consult the VictronConnect manual, especially the troubleshooting chapter.

Should all this fail to resolve the issue, scan through popular questions and answers regarding your product and ask the community of experts in the Victron Community In case the problem persists, contact the point of purchase for technical support. If the point of purchase is unknown, refer to the Victron Energy Support webpage.

7.1. The charger does not power up

With a normally working charger powered on and operational, the controller LED(s) - check the LED Indicators - will illuminate or blink and can communicate the charger status and battery voltages via VictronConnect. This is not possible with a device that does not turn on.

If the device does not power up, use the following steps to check why the charger is not operational.

  1. Check for mechanical damage to its housing and input/output terminals.

    If there is mechanical damage, this is probably the cause of the problem.

  2. Check the device for burn marks and a burning smell.

    If there are burn marks, this is probably the cause of the problem. Note that the device is potted; therefore, there may be some smell if it gets warm/hot while charging.

  3. Measure the battery voltage at the charger battery terminals with a multimeter to rule out possible problems with the wiring, fuses and/or circuit breakers in the path between the battery and charger.

    Depending on the result of the measurement, do the following:

    Battery voltage

    Operational state

    Action to take

    No voltage

    Off

    Restore the battery supply:

    - check external fuses

    - check for loose wires and damaged cables

    - check for bad crimps and pull-test the wires

    Correct voltage

    Off

    There might be a fault with the charger.

    Contact your Victron dealer or distributor.

    The charger was accidentally connected with the battery polarity reversed (see Polarity check before connecting the battery, not covered under warranty). Replace the charger.

    Correct voltage

    Off because the remote link is not connected

    Restore the remote link:

    The minimum requirement for the remote on/off terminal is a wire loop between the L- and H-pins.

    If a BMS controls the Orion's remote on/off, ensure this connection works as outlined in Remote on/off wiring.

7.2. The battery does not charge

There are a number of reasons why the Orion Smart might not charge the batteries. The following steps are intended to help with troubleshooting and corrective measures.

Reasons why the battery does not charge are:

  • Issues with the battery or system wiring

  • Incorrect settings, such as battery settings, input voltage lock-out and engine shutdown detection

  • A BMS or other device remotely controls the Orion Smart via its remote on/off

  • If not controlled by its remote on/off, it is missing the wire loop between L- and H-pin

  1. First, check if the VictronConnect app shows on the status page why charge is disabled.

    This can be because the remote input is inactive, the charger is disabled in the battery settings, or charge is disabled because input voltage lock-out and/or engine shutdown was detected.

    VictronConnect message

    Action to take

    Remote input inactive

    Consult the Remote on/off wiring and check the wiring.

    Check the terminal block for the remote on/off function is plugged in.

    Check for continuity if a wire loop or simple switch is used between L- and H-pin.

    If a BMS controls the remote input, ensure the ATC connection works.

    Disabled in settings

    Enable the charger in the battery settings.

    Input voltage lock-out

    See step 3.

    Engine shutdown detected

    See step 4.

  2. Check the battery wiring for damaged cables, loose connections, bad crimps or a blown battery fuse.

    Are the wires stripped to the correct length and tightened with the correct torque?

    What to check

    Action to take

    Are you using the correct cables, and are the wires stripped to the correct length, tightened with the correct torque and making good contact with the plug/terminals?

    See Recommended torque and Cable and fuse recommendations.Recommended torque

    Are there any burn marks on the terminals, or are the cables or connectors molten?

    Replace the device. This damage is usually not covered by warranty.

  3. Check the battery settings in the VictronConnect App.

    Incorrect battery settings can cause the charger to switch to absorption or float charging prematurely. The battery is then not fully charged.

    Description/Symptom

    Action to take

    The battery does not get fully charged.

    Check the absorption voltage in the battery settings and ensure it is set to the values the manufacturer recommends. See Charger Mode - Battery Settings.

    Make sure Charger mode is enabled in the settings. The power supply mode does not follow any charging algorithm, and the output voltage might be set too low.

    The battery does not get fully charged, but the Input voltage lock-out is enabled, and the input voltage is below the lock-out value.

    This is accompanied by the message "Charge is disabled due to: Input voltage lock-out" on the status page in the VictronConnect app.

    Ensure the input voltage is above the restart value or disable the input voltage lock-out feature in the settings. See Charger Mode.

    VictronConnect shows an output voltage higher than that of the charged battery as measured with a battery monitor or DMM.

    In general, the voltage measured at the output of the charger is always higher than that of the battery connected to that output as long as a high current is flowing.

    However, a bad connection between the output and the battery terminal can lead to the same symptom. Check step 2 again and ensure the lowest possible resistance for all connections.

  4. Check the engine shutdown detection settings in the VictronConnect App.

    Incorrect engine shutdown detection settings can result in the battery not being charged.

    Description/Symptom

    Action to take

    The battery will not charge because the start voltage value is too high for the selected alternator type (never reaches this voltage).

    This is accompanied by the message "Charge is disabled due to: Engine shutdown detected" on the status page in the VictronConnect app.

    Lower the start voltage value and ensure the alternator supports it. See Engine shutdown detection setup with VictronConnect.

    The battery is not fully charged because the shutdown voltage is set too high and the charger stops charging prematurely.

    This is accompanied by the message "Charge is disabled due to: Engine shutdown detected" on the status page in the VictronConnect app.

    Increase the shutdown voltage value. See Engine shutdown detection setup with VictronConnect

7.3. Bluetooth connection issues with VictronConnect

In the normal state, the blue Bluetooth LED should blink every 0.8 seconds when there is a connection between the VictronConnect app and the Orion-Tr Smart DC-DC Charger. See the LED Indicators section and learn more about the meaning of the different LED codes.

If not, check the following:

Blue LED status

LED duration

Action to take

Off

-

No input voltage: The Bluetooth controller is powered by the battery connected to the input terminals. Restore the battery supply.

Bluetooth has been disabled in the VictronConnect setting: This cannot be undone. We recommend leaving Bluetooth on at all times.

The Bluetooth option "Enabled for 30 seconds" was selected on the product info page. This means Bluetooth is active for 30 seconds after powering up the Orion. After 30 seconds, Bluetooth turns off until the next power-up. Disconnect and reconnect the battery input cable. Then connect to the Orion via VictronConnect within 30 seconds and set the Bluetooth option to 'Enabled'.

If none of the above applies, the unit may be faulty; submit a warranty claim.

Blinking

Every 0.8 seconds

There is already a Bluetooth connection active. Only one phone or tablet can connect via Bluetooth at a time; is perhaps another phone or tablet already connected? A clear indicator of this is that the Orion is visible in VictronConnect but greyed out.

For all other connection problems, please consult the VictronConnect manual for troubleshooting Bluetooth connection issues.

7.4. Error codes

The error codes are displayed in the VictronConnect app.

For the most up-to-date version of this list, see this link: https://www.victronenergy.com/live/mppt-error-codes.

Error 2 - Battery voltage too high
  • This error will auto-reset after the battery voltage has dropped. This error can be due to other charging equipment connected to the battery or a fault in the charge controller.

Error 26 - Terminal overheated
  • Power terminals overheated; check wiring, including the wiring type and type of strands, and/or fasten bolts if possible.

    This error will auto-reset.

Error 27 - Charger short circuit
  • This condition indicates an over-current condition on the battery side. It can occur when a battery is attached to the unit using a contactor. Or in case the charger starts up without a battery connected but connected to an inverter with a large input capacitance.

    This error will auto-reset. If the error does not auto-reset, disconnect the charge controller from all power sources, wait 3 minutes, and power up again. If the error persists, the charge controller is probably faulty.

Error 116 - Calibration data lost
  • If the unit does not work and error 116 pops up as the active error, the unit is faulty. Contact your dealer for a replacement.

    If the error is only present in the history data and the unit operates normally, this error can be ignored safely. Explanation: when the units power up for the first time in the factory, it does not have calibration data and an error 116 is logged. Obviously, this should have been cleared, but in the beginning, units left the factory with this message still in the history data.

Error 119 - Settings data lost
  • The charger cannot read its configuration and stopped.

    This error will not auto-reset. To get it working again:

    1. First, restore it to factory defaults (top right in VictronConnect, click on the three dots).

    2. Disconnect the charge controller from all power sources.

    3. Wait 3 minutes, and power up again.

    4. Reconfigure the charger

    Please report this to your Victron dealer and ask him to escalate it to Victron, as this error should never happen. Preferably include firmware version and any other specifics (VRM URL, VictronConnect screenshots or similar).
