F58BMS communication fault

Name in the manufacturer's documentation (user manual): BMS communication fault[1]

In plain words (editorial)

Communication between the hybrid inverter and the battery BMS is disconnected (reported when "BMS_Err-Stop" is active; the manual notes this item can be disabled on the LCD).

When to call a service technician: Check the battery communication cable; if the fault still exists, contact your installer or Deye support.
