7 Commissioning
1. Turn on the DC switch on the inverter. Once the DC input voltage is greater than 160V,
the inverter will display "No AC connection" and the LED indicator will turn red.
If other error message is displayed, please refer to Section 13. If you encounter any
technical problems, please contact Growatt support.
2. Turn on the circuit breaker or the switch between the inverter and the grid, the inverter
will start a countdown to perform a self-check. If no fault is found, the inverter will be
connected to the grid.
3. When the inverter is working properly, the leaf-shaped indicator will turn green.
4. Finish the commissioning process.
8 Working mode
8.1 Operating mode
In this mode, the inverter works normally.
Ø When the grid-connected requirements are met - the DC voltage is greater than
200V, and the grid voltage and frequency are within the permissible range, the
inverter will convert the DC power generated by the solar panels into AC power and
feeds it to the grid with the green LED indicator on.
Ø When the DC voltage falls below 160V, the inverter will automatically disconnect
from the grid and exit the operating mode. It will enter the operating mode and be
connected to the grid automatically once the requirements are met.
8.2 Failure mode
When an unexpected condition occurs, such as a system failure or an inverter failure, the
inverter will report the error message on the screen. In failure mode, the leaf-shaped
indicator will turn red and the inverter will be disconnected from the grid.
When PV power is insufficient or no PV power is generated, the inverter will shut down
automatically. In shutdown mode, the inverter does not consume energy from the grid or
the solar panels, and the display and the indicators will be off.
8.3 Shutdown mode

For the device to begin operation, a country data set must be configured
correctly. If no country data set is configured in 30s, it will operate
according to the default value: AS/NZS477.2 for Australia and
VDE0126-1-1 for other regions.
Information
When the inverter initializes, the OLED screen lights up automatically. Once the PV power
is sufficient, it will display "PV Inverter". Tap the touch button to scroll through the
country options until the desired selection is displayed. For instance, to select Germany,
tap the touch button until "VDE0126" is displayed; long press the button for 5s and the
screen will indicate that the configuration is completed.
