If the descriptions shows "Unknown" it's not (yet) found out what it means. If you see something in a documentation or App I am happy to add the message.

Hi. User manual:

211: No input

Check whether this port is connected to a PV module.
If a PV module is connected, check the DC cable connections between the connector and the PV module.

220: Input undervoltage Check the input voltage at the PV-3 connector.

52: unknown -> Please ask support.

Have you ever checked the connections? A comparison measurement with a voltage tester of the voltage on several modules could show whether a module is defective. Remember that you should not plug or unplug anything under load.
