This chapter introduces the related operations during the use of the inverter, which mainly involves
pre-operation inspections, grid-connected operation of the inverter, inverter shutdown, and precautions
for daily maintenance and repair of the inverter.
6.1 Inspection before running
The following items must be checked strictly before running the PV grid-connected inverter
(including but not limited to the following items):
(1) Confirm the installation site of the inverter meet requirements of section 4.2.2 to ensure convenient
installation, disassemble, operation and inspection on the inverter;
(2) Confirm the mechanical installation of the inverter meet requirements of section 5.3;
(3) Confirm the electrical connection of the inverter meet the requirements of section 4.4;
(4) Confirm all the switches are in “OFF” state;
(5) Confirm the open-circuit voltage of PV module conforms to the parameter requirements of inverter
DC side in appendix;
(6) Confirm the electrical safety marks on the installation site is clear enough.
 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.
6.2 Inverter grid-connected running
Please strictly follow the steps below to turn on the inverter and complete the grid-connected
operation of the inverter:：
Note

For the first operation of the inverter, a country must be selected to set
grid-connected standards.
 Please keep the inverter powered on for at least 30 minutes, and complete the
charging of the built-in clock battery of the inverter to ensure the normal operation
of the clock!
(1) Make sure that the inspection items in Section 6.1 meet the requirements;
(2) Turn on the AC side circuit breaker of the inverter public grid;
(3) Turn on the DC switch integrated in the inverter;
(4) Turn on the switch on the DC input side of the photovoltaic string;
(5) Observe the status of the inverter's LED lights or the information displayed on the LCD
screen (refer to section 2.6 for LED status lights and LCD display information);
(6) Wait for the inverter to connect to the grid successfully.
