• When the photovoltaic panel generates enough power, the inverter will start
automatically.
• Check the status of the indicator lights and and LCD screen. If the inverter
starts succefully, the indicator light will ash in green, and the LCD screen will
display the main interface. The green light will ash when inverter is turned
on, and it will always be on after grid connection. If the battery is connected,
the blue light will always be on as long as the inverter is turned on, regardless
of whether it is connected to the grid.
• If the indicator light does not light up and the interface does not appear on
the screen, please check the following:
-All connections are correct.
-All external disconnect switches are closed.
-The DC switch of the inverter is set to the “ON” position.
The following are 3 dierent states of inverter operation, which means that the
inverter starts successfully.
Waiting:
When the DC output voltage of the photovoltaic panel is higher than 110V
(lowest starting voltage) and lower than 80V (lowest working voltage), the in-
verter waits for checking.
Checking:
The inverter will automatically detect the DC input. When the DC input voltage
of the photovoltaic panel is higher than 90V and the photovoltaic panel has
enough energy to start the inverter, the inverter will enter the checking state.
Normal:
When the inverter is working normally, the green light is always on. At the
same time, the power is fed back to the grid, and the LCD displays the output
power.
Warning!
The input terminal of the inverter can be opened only when
all the installation work of the inverter has been completed. All
electrical connections must be performed by professionals in
accordance with local regulations.
If it is the rst time to boot, please follow the prompts to enter the setting inter-
face.
