-A cause for this error can be switching on a very large load on the battery side.+Possible causes for an over-current on the battery terminals: 
 +  * switching on/off a very large load on the battery side
 +  * sudden change in irradiance causing a temporary over-power in the mppt.

 +Possible solutions
 +  * if possible provide adequate cooling for the unit, a cooler unit can handle more current.
 +  * reduce the load on the inverter.
 +  * charge the battery before using the inverter, at higher battery voltages the same amount of power requires less current.

 Possible reasons for this error to occur: 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.+ * The Battery voltage (12/24/36/48V) is set incorrectly. Use VictronConnect to set the right Battery 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.  * 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. +

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.
