Hallo zusammen,
seit einigen Tagen scheint der Wechselrichter inaktiv zu sein. Die Leistung der PV- Module wird nicht weitergeleitet, der Akku wird nicht geladen. Der Hausverbrauch wird von Netzbetreiber versorgt. Es wird der Alarm Code 222 ausgegeben. Kennt jemand dieses Problem und hat einen Lösungsansatz?

This is the text for the alarm code 222

It is suggesting that you have a fault with your battery or BMS, it is asking for a charge but the inverter is not responding - I would recommend you check all your connections between the inverter and batteries and then do a complete shutdown and then power up your inverter and batteries - on the inverter isolate your solar PV, then open the AC isolator, on the battery power them off, and open the battery isolator (dc switch on the battery).
Wait for the inverter screen to go blank, then reverse that process.

If it is still reporting an error I would suggest you contact your local Fox ESS service and they will be able to remotely diagnose faults, it could be a charger fault in your inverter.
