-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.

-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.

-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.
