OPERATION
INSPECTION BEFORE OPERATION
The following items must be checked strictly before running the PV grid-connected
inverter (including but not limited to):
(1) Ensure the installation site meet the requirement mentioned in installation pace for
easy installation, removing, operation and maintenance;
(2) Ensure the mechanical installation meet the requirement mentioned in table of
installation pace;
(3) Ensure the electrical installation meet the requirement mentioned in table of cable
specifications;
(4) Ensure all switches are "off";
(5) Ensure the open circuit voltage of the PV module complies with the DC side parameter
requirements(in the appendix) of inverter;
(6) Ensure all electrical safety precautions are clearly-identified on the installation site.
 In order to ensure a safe, normal and stable operation of the PV power
generation system, all the newly installed, renovated and repaired PV grid -
connected power generation system and its grid -connected inverter must
undergo inspection before running .
GRID-TIED OPERATION
Start the inverter according to below steps to achieve grid-connected operation of the
inverter:
 Must to select the country to set grid-connected standard during the initial
operation of the inverter
Note Note
 Keep the power-on state of the inverter for at least 30 minutes, and complete
the charging of built-in clock battery of the inverter to ensure the clock can run
normally!
Please start the inverter as follows:
(1) Ensure the requirements mentioned in inspection before operation are met;
(2) Switch on the breakers at the AC side;
(3) Switch on the integrated DC switch;
(4) Switch on the switch on the DC side;
(5) Observe the LED indicator state of the inverter and the information displayed by LCD.
Refer to chapter 6 for LED state indicator and LCD display information.
Run
Green indicator flickers, other indicators are off: Inverter is powered on and
under self-inspection, wait for enough light to fulfill grid -connected condition;
Run
Green indicator on, others off : The inverter is in power generation after self -
inspection----successful commissioning.
"Warn" or "Fault" indicator is on or flickers: inverter is powered on but system fault
occur. Refer to LCD screen to check the fault code in LCD display, stop the inverter as per
STOPPING, and rule out faults according to TROUBLESHOOTING. After all the faults are
removed, repeat the operations
