5.1 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 fulfill 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 fulfills requirements of section 4.3;
(3) Confirm the electrical connection of the inverter fulfills the requirements of section 4.4;
(4) Confirm all the switches are in
“OFF” state;
(5)
Confirm the open-circuit voltage of PV component 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.
5.2 Inverter grid-connected running
Start the inverter according to below steps to achieve grid-connected operation of the inverter:
Note
It is a must to select the country to set grid-connected standard
during the initial operation of the inverter, see details at section 6.5.
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!
(1) Confirm the requirements in section 5.1 are fulfilled;
(2) Close the breaker on inverter public grid AC side;
(3) Close the integrated DC switch of the inverter;
(4) Close the circuit switch on PV string DC input 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.
