8.5. Error Codes
8.5.1. 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.
8.5.2. Error 3, Err 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.
8.5.3. 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.
8.5.4. Error 6, Error 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.
8.5.5. Error 8 - Remote battery voltage sense failure (connection lost)
Check if the V-sense connector is properly connected to the battery terminals.
8.5.6. Error 11 - Battery high ripple voltage
High DC ripple is usually caused by loose DC cable connections and/or too thin DC wiring. After the inverter has switched off due
to high DC ripple voltage, it waits 30 seconds and then restarts.
After three restarts followed by a shutdown due to high DC ripple within 30 seconds of restarting, the inverter will shutdown and
stops retrying. To restart the inverter, switch it Off and then On.
Continuous high DC ripple reduces the inverter life expectancy
8.5.7. Error 14 - Battery low temperature
The charger is stopped to avoid charging LiFePO4 batteries at low temperature as this damages the cells.
8.5.8. Error 20 - Maximum Bulk-time exceeded
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.
AC Chargers
This protection is 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.
8.5.9. Error 22, 23 - Internal temperature sensor failure
The internal temperature measurements are out of range. Disconnect all wires, and then reconnect all wires, to restart the unit.
This error will not auto-reset. If the error remains, please contact your dealer, there might be a hardware defect.
8.5.10. 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.
