11.4. Charger error code overview

This overview lists all possible error codes that can be generated by a solar charger or AC charger.

The error codes are displayed on the charger display, remote display or via a connected GX device.

Note

Note that not all of these errors might apply to your charger model. Some error types only apply for solar chargers, for AC chargers or are specific only to certain models within a charger group.

Error 2 - Battery voltage too high

The battery voltage is higher than expected. This error can be due to other charging equipment connected to the battery or a fault in the charger. This error can also occur if the battery voltage (12, 24, 36 or 48V) is set to a lower voltage than the connected battery. This error will auto-reset after the battery voltage has dropped.

Error 3 and/or 4 - Remote temperature sensor failure

Check if the T-sense connector is properly connected to a remote temperature sensor. Most likely cause: the remote T-sense connector is connected to the BAT+ or BAT- terminal. This error will auto-reset after proper connection.

Error 5 - Remote temperature sensor failure (connection lost)

Check if the T-sense connector is properly connected to a remote temperature sensor. This error will not auto-reset.

Error 6 and/or 7 - Remote battery voltage sense failure

Check if the V-sense connector is properly connected to the battery terminals. Most likely cause: the remote V-sense connector is connected in reverse polarity to the BAT+ or BAT- terminals.

Error 8 - Remote battery voltage sense failure (connection lost)

Check if the V-sense connector is properly connected to the battery terminals.

Error 17 - Controller overheated despite reduced output current

This error will auto-reset after charger has cooled down. Check the ambient temperature and check for obstructions near the heat sink.

Error 18 - Controller over-current

This error will auto-reset. If the error does not auto-reset disconnect the charger from all power-sources, wait 3 minutes, and power up again. If the error persists the charger is probably faulty. A cause for this error can be switching on a very large load on the battery side.

Error 20 - Maximum Bulk-time exceeded

For solar chargers:

The maximum bulk time protection is a feature that was in the chargers when they were just released (2015 or earlier) and later the feature was removed.

If you do see this error, then update to the latest firmware.

If you then still have the error, perform a reset to factory defaults of the configuration, and reconfigure the solar charger.

For AC chargers:

This protection is by default enabled on the Skylla-i and the Skylla IP44.

This error is generated when the battery-absorption-voltage is not reached after 10 hours of charging.

The feature of this safety protection is to detect a shorted cell; and stop charging.

Error 21 - Current sensor issue

The current measurement is out of range.

Disconnect all wires, and then reconnect all wires, to make the charger restart. Also, make sure the minus on the MPPT charge controller (PV minus/Battery minus) is not bypassing the charge controller.

This error will not auto-reset.

If the error remains, please contact your dealer, there might be a hardware defect.

Error 24 - Fan failure

This error indicates that the fan is powered on but the circuit does not measure any current draw by the fan. Most likely its either broken or obstructed.

Please contact your dealer, there might be a hardware defect.

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 28 - Power stage issue

This error will not auto-reset.

Disconnect all wires, and then reconnect all wires. If the error persists the charger is probably faulty.

Note that this error was introduced in v1.36. So when doing an update, it might look like the firmware update caused this issue; but it doesn't. The solar charger was then already not performing 100% before the update; updating to v1.36 or later merely made the issue more visible. The unit needs to be replaced.

Error 33 - PV over-voltage

This error will auto-reset after PV-voltage has dropped to safe limit.

This error is an indication that the PV-array configuration with regard to open-circuit voltage is critical for this charger. Check configuration, and if required, re-organise panels.

Error 34 - PV over-current

The current from the solar-panel array has exceeded the maximum allowed current.

This error could be generated due to an internal system fault.

Disconnect the charger from all power-sources, wait 3 minutes, and power-up again. If the error persists the controller is probably faulty, contact your dealer.

Error 38 and/or 39 - PV Input shutdown

To protect the battery from over-charging the PV input is shorted.

Possible reasons for this error to occur:

  • The Battery voltage (12/24/48V) is set, or auto-detected, incorrectly. Use VictronConnect to disable auto-detect and set the Battery Voltage to a fixed voltage.

  • There is another device connected to the battery, which is configured to a higher voltage. For example a MultiPlus, configured to equalise at 17 Volts, while in the MPPT this is not configured.

  • The battery is disconnected using a manual switch. Ideally the charger should be switched off before disconnecting the battery, this avoids a voltage overshoot on the charger output. If necessary the voltage trip-level for the PV Short protection can be increased by raising the Equalization voltage set-point (note: equalization does not have to be enabled in this case).

  • The battery is disconnected using a Lithium charge relay connected to the “allow-to-charge” output of a BMS. Consider wiring this signal to the Remote terminal of the charger instead. This shuts down the charger gracefully without creating a voltage overshoot.

Error recovery:

  • Error 38: First disconnect the solar panels and disconnect the battery. Wait for 3 minutes, then reconnect the battery first and next the panels.

  • Error 39: The charger will automatically resume operation once the battery voltage drops below its maximum voltage setting (normally Equalisation or Absorption voltages), for 250V versions or float voltage for the other units. It can also takes a minute to reset the fault.

If the error persists the charge controller is probably faulty.

Error 40 - PV Input failed to shutdown

If the charger is unable to turn off the PV input, it will go into a safe mode in order to protect the battery from over-charging or having a high voltage on the battery terminals. In order to do that, the charger will stop charging and disconnect its own output. The charger will become faulty.

Information 65 - Communication warning

Communication with one of the paralleled chargers was lost. To clear the warning, switch the charger off and back on.

Information 66 - Incompatible device

The charger is being paralleled to another charger that has different settings and/or a different charge algorithm. Make sure all settings are the same and update firmware on all chargers to the latest version.

Error 67 - BMS Connection lost

The charger is configured to be controlled by a BMS, but it does not receive any control messages from a BMS. The charger stopped charging, as a safety precaution.

This error only shows when there is solar power available and thus the charger is ready to initiate charging. It does not show at night. In case there is a permanent problem, the error will raise in the morning and clear at night, and so forth.

Check the connection between the charger and the BMS.

How to reconfigure the charger to standalone mode:

The charger automatically configures themselves to be BMS-controlled when they are connected to one; either direct or via a GX Device. And that setting is semi-permanent: power cycling the charger will not reset it.

Here is what needs to be done to make the charger operate in stand-alone mode again, ie. not controlled by a BMS:

  • VE.Can solar chargers, go into the setup menu, and change setting ‘BMS’ from ‘Y’ to ‘N’ (setup item 31).

  • VE.Direct solar chargers, reset the charger to factory defaults with VictronConnect, and then reconfigure it.

Error 68 - Network misconfigured

Applies to SmartSolar/BlueSolar chargers VE.Can (FW version v1.04 or higher) and SmartSolar VE.Direct chargers (FW version v1.47).

To clear the error on the SmartSolar VE.Direct chargers update the FW version to v1.48 or higher.

To clear the error on the SmartSolar/BlueSolar chargers VE.Can, update the software. If the error persists, it will be because the charger is connected with both a VE.Direct cable and on VE.Can. That is not supported. Remove one of the two cables. The error will disappear and the charger will resume normal operation, within a minute.

Background:

Error 68 indicates that the charger detects multiple conflicting network sources, with the same priority, trying to send the same information to the charger. VE.Can and VE.Direct interfaces have both the same priority level, and BLE (using VE.Smart Networking) has a lower priority.

Having a higher priority level means that, if the same information (e.g. Battery voltage sense) is being received from both VE.Can and BLE (using VE.Smart Network) by the charger, the information on VE.Can will be used and the one coming from BLE will be ignored.

Now, if the same information is being received from two interfaces that have the same priority level (as VE.Can and VE.Direct), the charger does not know how to prioritize those, causing error 68 to be triggered.

Error 114 - CPU temperature too high

This error will reset after the CPU has cooled down. If the error persists, check the ambient temperature and check for obstructions near the air inlet and outlet holes of the charger cabinet. Check manual for mounting instructions with regard to cooling. If error persists the 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 very 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.

SmartSolar models (not the BlueSolar models): upgrading to v1.4x firmware is a one-way trip, you cannot go back to an older firmware version once you upgrade to v1.4x. Reverting to older firmware gives error 116 (calibration data lost), this can be fixed by re-installing the v1.4x firmware.

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. Click on the three dots Menu_3-dot_symbol_VictronConnect.svg located in the top right in VictronConnect.

  2. Disconnect the charge controller from all power-sources.

  3. Wait 3 minutes, and power up again.

  4. Reconfigure the charger.

Please do 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).
