 If you are using firmware v1.08 or newer this error indicates that the internal dc voltage is too high. This error will auto-reset. 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.

 Possible reasons for this error to occur:
 	* The Battery voltage (12/24/36/48V) is set incorrectly. Use VictronConnect to set the right Battery Voltage.
-	* There is another charger connected to the battery, which chargers at a higher voltage. The solution is to make sure that charge voltages configured in the MPPT match the other chargers in the system. In case equalisation is set in one of the other chargers, especially at higher voltages such as 16 or 17V, then configure the same in the MPPT. Even when the MPPT is not used for equalisation.
+	* 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, without first disconnecting the PV array. Which is not ideal but otherwise harmless. If necessary the voltage trip-level for the PV Short protection can be increased by raising the Equalization voltage set-point; which works even when Equalization itself is not enabled .
-	* 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.
 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 38 and Errors 84 to 87: 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 its maximum voltage setting (normally Equalisation or Absorption voltages), for 250V versions or float voltage for the other units. It can also takes a minute to reset the fault.

-If the error immediately pops up when switching on the inverter (without load) on a full battery the cause is most likely a broken internal fuse.

 ==== Err 55, Err 56, Err 58 - Inverter self test failed ====
 The inverter performs diagnostic tests before it activates its output. In the case that one of these tests fails an error message is displayed and the inverter does not turn on.
