Other possible problems:
If there is no information on the LCD display, please check whether the connection of the inverter with PV
generator or the grid is correct.
If the PV voltage is higher than 200V, but the inverter does not work, please call the service.
During periods of insufficient sunlight, the inverter may continuously start up and shut down. This is due to
insufficient power generated by PV modules. If the problem continues, please call the service.
The safety information in the instructions must be carefully read.
