 The feature of this safety protection is to detect a shorted cell; and stop charging.
 ==== Err 21 - Current sensor issue ====
+The current measurement is out of range.
+Disconnect all wires, and then reconnect all wires, to make restart the charger. 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.
-Disconnect all wires, and then reconnect all wires. Also, make sure the minus on the MPPT charge controller (PV minus/Battery minus) is not bypassing the charge controller.
+If the error remains, please contact your dealer, there might be a hardware defect.
+==== Err 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.
-If the error remains, please contact the dealer, there might be a hardware defect.
+Applies to Skylla-IP44 & Skylla-IP65 chargers only.
 ==== Err 26 - Terminal overheated ====
 Power terminals overheated, check wiring, including the wiring type and type of strands, and/or fasten bolts if possible.

 To clear the error on the SmartSolar VE.Direct MPPTs update the FW version to v1.48 or higher.
-To clear the error on the SmartSolar/BlueSolar MPPTs VE.Can, update the software. If the error persists, make sure the disconnect the VE.Direct or VE.Can cable from the charger. Once the conflict is resolved the error will disappear and the charger will resume normal operation, within a minute.
+To clear the error on the SmartSolar/BlueSolar MPPTs 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.
-Note: Connecting a Solar charger on both VE.Can and VE.Direct is not supported.
+__Background__
-The error occur when 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.
+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 has the same priority level (as VE.Can and VE.Direct), the charger does not know how to prioritize those, so then error 68 will be triggered.
+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.

+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).
