7.4.24. Error 50, Error 52 - Inverter overload, Inverter peak current
Some loads like motors or pumps draw large inrush currents in a start-up situation. In such circumstances, it is possible that the
start-up current exceeds the over current trip level of the inverter. In this case the output voltage will quickly decrease to limit the
output current of the inverter. If the over current trip level is continuously exceeded, the inverter will shut down: wait 30 seconds
and then restart.
The Inverter can supply more power than the nominal power level for a short time. If the time is exceed the inverter stops.
After three restarts followed by another overload within 30 seconds of restarting, the inverter will shutdown and remain off. To
restart the inverter, switch it Off, then On.
If the error persists reduce the load on the AC out terminal by switching off or disconnecting appliances.
7.4.25. Error 51 - Inverter temperature too high
A high ambient temperature or enduring high load may result in shut down to over temperature. Reduce load and/or move
inverter to better ventilated area and check for obstructions near the fan outlets.
The inverter will restart after 30 seconds. The inverter will not stay off after multiple retries.
7.4.26. Error 53, Error 54 - Inverter output voltage
If the battery voltage is getting low and a large load is applied to the AC output the inverter is unable to maintain the proper output
voltage. Re-charge the battery or reduce the AC loads to continue operation.
7.4.27. Error 55, Error 56, Error 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.
First try to restart the inverter, by switching it Off, and then On. If error persists the inverter is probably faulty.
7.4.28. Error 57 - Inverter ac voltage on output
There is already AC voltage on the AC out terminal before switching on the inverter. Check that the AC out is not connected to a
mains outlet or to another inverter.
This error will not auto-reset. Check the installation and restart the unit using the power-switch.
7.4.29. Notification 65 - Communication warning
Communication with one of the paralleled controllers was lost. To clear the warning, switch the controller off and back on
7.4.30. Notification 66 - Incompatible device
The controller is being paralleled to another controller that has different settings and/or a different charge algorithm.
Make sure all settings are the same and update firmware on all chargers to the latest version
7.4.31. Error 67 - BMS Connection lost
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, as a safety precaution.
This Error only shows when there is solar power available and thus the Solarcharger is ready to initiate charging. It does not show
at night. And in case there is a permanent problem, the error will raise in the morning and clear at night, and so forth.
Check the connection between the charger and the BMS.
How to reconfigure the charger to standalone mode
Our Chargers and Solarchargers automatically configure themselves to be BMS-controlled when they are connected to one;
either direct or via a GX Device. And that setting is semi-permanent: power cycling the charger will not reset it.
Here is what needs to be done to make the charger operate in stand-alone mode again, ie. not controlled by a BMS:
• VE.Can solar chargers, go into the setup menu, and change setting 'BMS' from 'Y' to 'N' (setup item 31).
• VE.Direct solar chargers, reset the charger to factory defaults with VictronConnect, and then reconfigure it.
