If the error does not auto-reset disconnect the charge controller from all power-sources, wait 3 minutes, and power up again.

  * The Battery voltage (12/24/36/48V) is set incorrectly. Use VictronConnect to set the right Battery Voltage.  * 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. +

-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 by reducing the output voltage to the battery base voltage (12V/24V/36V/48V), as a safety precaution.+ 
 +This error shows when the charger is configured to be controlled by a BMS, but does not receive any BMS control messages. In that situation, the charger stops charging by reducing its output voltage to the battery base voltage (12V/24V/36V/48V). This is a safety mechanism, the reason to still enable the output is to allow a system to self-recover from a battery low situation.
