when the control board is correctly connected to the communication board, the LCD screen will display the
current status of the inverter, as shown in the figure below.
Inverter states include:
Wait:
inverter is waiting to Check the state at the end of the reconnection time. In this state, the PV voltage
must be higher than 250 V, the grid voltage value must be between the minimum and maximum permissible
limits, as should the other grid parameters; otherwise, the inverter will go into a permanent error state.
Check:
inverter is checking the insulation resistance, relays and other safety parameters. It also runs a self-
test to ensure that the software and hardware of the inverter are functional. The inverter switches to the
error state or permanent error state if errors occur.
Normal:
The inverter is functioning normally and is feeding power into the grid; the inverter will go into a
permanent error state if any errors are found.
Error:
inverter has encountered a permanent error. It should then return to the normal state if the errors
disappear. If the error continues, please check the inverter according to the error code.
Permanent:
inverter has encountered a permanent error. The installer must debug this type of error
according to the code found in order to bring the inverter back to its proper functioning.
If the control board and communication board are not connected, the interface of the LCD display appears as
shown in the figure below.
