DC input voltage is too low for grid power feed operation
Behaviors
Short interruption of grid power feed operation.
The inverter returns to the startup phase.
Status Code Class 3
Class 3 status codes (state codes that start with a three, i.e., 3xx), may occur while feeding energy into the grid, but generally do not cause the process to be interrupted permanently.
The inverter temporarily disconnects automatically from the grid, the grid is then monitored as specified and the inverter attempts to resume feeding energy into the grid.

Solutions for this Error
Remedies
- Wait for sufficient solar radiation
Additional Info
Status codes 306 (Power low) and 307 (DC low) appear naturally every morning and evening due to low solar irradiance. These codes may also appear when the array is covered in snow or during other low light conditions. These codes are typically not the result of a fault.
