After Home Assistant fully discharged my battery to 10% I found myself with an inverter alarm - Tz Protect Fault and being unable to change the status to manual force charge. This is what I did to fix the issue, it may help some. Note the alarm is still showing in the app but at least now I seem to be able to connect via modbus and home assistant. To add don't forget to unlock the inverter in home assistant otherwise it will fail to change the statuses.
