Ø After the inverter is checked, then conduct the following
steps
If it is the first time to boot, please follow the prompts to enter the setting interface.
Ø Before operation, check the inverter according to the following steps

5.9 Inverter Operation

a) Check that the inverter is well xed on the wall.
b) Ensure that all ground wires are well tightened.
c) Ensure that all DC and AC circuit breakers are disconnected.
d) Ensure that all ground wires are well tightened.
e) The AC output terminal is correctly connected to the mains.
f ) Ensure that all photovoltaic panels and inverter are properly connected.
Unused DC connectors should be blocked with caps.
Steps to start the inverter
- Turn on the AC switch between the X1-Hybrid G4 and the power grid.
- (Optional) Remove the locking screw from the DC switch.
- Turn on the DC switch between the PV string and the X1-Hybrid G4 if there is
any.
- Turn on the DC switch at the bottom of the X1-Hybrid G4 .
When the photovoltaic panel generates enough power, the inverter will start
automatically.
Check the status of the LED and LCD screen, the LED is green, and the LCD
screen displays the main interface.
If the LED is not green, 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 different states of inverter operation, which means that
the inverter starts successfully.
Waiting: When the DC output voltage of the photovoltaic panel is higher than 70V
(lowest starting voltage) and lower than 90V (lowest working voltage), the inverter
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.
Notice!
If it is the first time to operate the inverter, the system will
automatically display setup guide. Please follow the setup guide
to complete the basic inverter settings.
