 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.

 ==== Err 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 Solarcharger is ready to initiate charging. It does not show at night. And 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 reset the charger, to de-couple it from the BMS__
+__How to reconfigure the charger to standalone mode__
-When the charger needs to operate in stand-alone mode again, not controlled by a BMS, it needs to be reset:
+Our Chargers and Solarchargers automatically configure 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.
-Note that (solar-)chargers automatically configure themselves to be BMS-controlled when they are connected to one; either direct or via a Color Control GX or Venus GX.
 ==== Err 68 - Network misconfigured ====
+Applies to SmartSolar/BlueSolar MPPTs VE.Can (FW version v1.04 or higher) and SmartSolar VE.Direct MPPTs (FW version v1.47).
-The charger detects multiple conflicting network sources trying to take control of the charger.
+To clear the error on the SmartSolar VE.Direct MPPTs update the FW version to v1.48 or higher.
-Applies to SmartSolar MPPTs and SmartSolar MPPTs VE.Can.
-The typical reason for the error to show is that the charger is configured to operate in parallel using our [[https://www.victronenergy.com/live/victronconnect:ve-smart-networking|wireless VE.Smart protocol]]; and at the same time it is part of an [[https://www.victronenergy.com/live/ess:start|Energy Storage System (ESS)]]. Or its used in an installation with an intelligent battery. In all those cases, the charger is being externally controlled (by ESS and/or intelligent battery), and should therefor not at the same time be configured for parallel operation.
+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.
-Resolution: disable the parallel operation by connecting VictronConnect, going to settings, then "VE.Smart networking" and choose "Leave network".
+__Background__
-For SmartSolar MPPT VE.Can only, also make sure its not connected to a [[https://www.victronenergy.com/live/venus-os:start|GX Device]] via both VE.Can and VE.Direct. Either disconnect the VE.CAN cable or the VE.Direct cable.
+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.
-Once the conflict is resolved the error will disappear and the charger will resume normal operation, usually within a minute.
+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.

+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).
