 ==== Err 18 - Controller over-current ====
 This error will auto-reset.
-Disconnect the charge controller from all power-sources, wait 3 minutes, and power up again.
+If the error does not auto-reset disconnect the charge controller from all power-sources, wait 3 minutes, and power up again. If the error persists the charge controller is probably faulty.
-If the error persists the charge controller is probably faulty.
+A cause for this error can be switching on a very large load on the battery side.
 ==== Err 20 - Maximum Bulk-time exceeded ====
-This error can only occur when the maximun bulk-time protection is active.
-This error will not auto-reset.
-This error is generated when the battery-absorption-voltage is not reached after 10 hours of charging.
-This protection is default disabled in all Solar Chargers.
+=== 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.
-It is default enabled on the Skylla-i and the Skylla IP44.
+If you do see this error, then update to the latest firmware.
-Our advice is to not enable it on solar chargers.
+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.

 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.
-==== Err 38 - Input shutdown due to battery over-voltage ====
+==== Err 38, Err 39 - PV Input shutdown ====
-To protect the battery from over-charging the panel input is shut down. To recover from this condition first disconnect the solar panels and disconnect the battery. Wait for 3 minutes reconnect the battery first and next the panels.
+To protect the battery from over-charging the panel input is shorted.
-A common reason for this error to occur is that the Battery voltage (12/24/48V) is set, or auto-detected, incorrectly.
+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.
-Use VictronConnect to disable auto-detect and set the BatteryVoltage to a fixed voltage.
+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 the float level for 1 minute.
 If the error persists the charge controller is probably faulty.
 ==== Information 65 - Communication warning ====
 Communication with one of the paralleled controllers was lost. To clear the warning, switch the controller off and back on

 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 ====
+The charger detects multiple conflicting network sources trying to take control of the charger.
+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, and should not at the same time be configured for parallel operation.
+Resolution: disable the parallel operation by connecting VictronConnect, going to settings, then "VE.Smart networking" and choose "Leave network".
+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.
+Once the conflict is resolved the error will disappear and the charger will resume normal operation, usually within a minute.

 ==== Err 116 - Calibration data lost ====
-The unit is faulty, contact your dealer for a replacement.
+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.
 ==== Err 119 - Settings data lost ====
 The charger cannot read its configuration, and stopped.
