8.11.8. 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.

8.11.9. Error 33 - PV over voltage

This error will auto-reset after the PV voltage has dropped to a 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.
For more information, refer to the

8.11.10. Error 38, 39 - PV Input shutdown

When these errors show, the PV Input is internally shorted to protect the battery from overcharging. Prior to any other
troubleshooting, make sure to update to the latest firmware version.
Possible reasons for this error to occur:
• The "Battery voltage" parameter (12/24/36/48V) is set incorrectly. Use the VictronConnect app to set the correct "Battery
voltage" parameter.
• Another device is connected to the battery, configured to a higher voltage. For example, an inverter/charger is configured to
equalise at 17 Volts, while this is not configured in the solar charger.
Error recovery:
• Error 38: First, disconnect the solar panels and then disconnect the battery. Wait for 3 minutes, then first reconnect the battery
and then 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). It can also take a minute to reset the fault.
• If the error persists, the solar charger is probably faulty.

8.11.11. Error 80 to 88 - PV Input shutdown

When these errors show, the PV Input is internally shorted in order to protect the battery from over-charging.
Prior to any other troubleshooting, make sure to update to the latest firmware version.
Possible reasons for this error to occur:
• The "Battery voltage" (12, 24, 36 or 48V) parameter is set incorrectly. Use the VictronConnect app to set it to the correct battery
voltage.
• Another device is connected to the battery with a higher charge voltage configuration. For instance, a MultiPlus is configured to
equalise at 17V, while the solar charger has not been configured for equalise charging.
Error recovery:
• Ensure that the solar charger is running the latest firmware.
• Errors 80 to 83: First, disconnect the solar panels, then disconnect the battery and then follow the procedure as described in
the ??? chapter.
• Errors 84 to 87: First, disconnect the solar panels and disconnect the battery. Wait for 3 minutes, then first reconnect the battery
and then reconnect the panels.
• If the error persists, the solar charger is probably faulty.

8.11.12. 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.
