5.8 Check All Below Steps Before Starting Inverter

Ø
After the inverter is checked, then conduct the following
steps
Make sure that the inverter is fixed on the wall.
Ensure that all ground wires are grounded.
Confirm that all DC lines and AC lines are connected.
Make sure the CT are connected.
Make sure the battery is well connected.
Turn on the Load switch and EPS(Off-grid) switch.
Turn on the battery switch.
Long press the "Enter "key for 5 seconds to exit the Off mode.
(The mode is factory defaulted as Off Mode)

5.9 Inverter Operation

Ø Before operation, check the inverter according to the following steps
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 inverters are properly
connected. Unused DC connectors should be blocked with caps.
Ø Start the inverter
Steps to start the inverter
- Turn on the AC switch between the X3-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 X3-Hybrid G4 if
there is any.
- Turn on the DC switch at the bottom of the X3-Hybrid G4 .
When the photovoltaic panel generates enough power, the inverter
will start automatically.
- If the battery port of the X3-Hybrid G4 is connected to a battery, turn
on the auxiliary power switch of the battery and then the battery
switch.
Check the status of the LED and LCD screen, the LED is blue, and the
LCD displays the main interface.
If the LED is not blue, 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 160V (lowest starting voltage) and lower than 180V (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 200V and the
photovoltaic panel has enough energy to start the inverter, the inverter
will enter the checking state.
