Check as follows before operation (including but not limited to):
(1) Ensure the installation site meet the requirement mentioned in section 4.2.2 for easy
installation, removing, operation and maintenance;
(2) Ensure the mechanical installation meet the requirement mentioned in section 4.3;
(3) Ensure the electrical installation meet the requirement mentioned in section 4.4;
(4) Ensure all switches are “off”;
(5) Ensure the voltage meet the requirement mentioned in chapter 10;
(6) Ensure all electrical safety precautions are clearly-identified on the installation site.
z Do check as above before any operation if the system or inverter needs to be

5.2 Grid-tied operation
z When power on the inverter for the first time, please refer to section 6.5 to
complete grid certification choice.
z K
eep the inverter power on at least 30 minutes to charge for the internal clock
battery.
Please start the inverter as follows:
(1) Ensure the requirements mentioned in section 5.1 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 indicators and information displayed on the screen. Refer to chapter 6

occurs. Please refer to section 6.3 for detailed information, and then stop as the
section 5.3 mentioned, finally settle the problems as chapter 8. If all faults are
do as chapter 5 mentioned.
(9) Refer t o section 6.4.4 to set the inverter time according to local time.
(10) The default DC input mode is “independent”. Please refer to section 6.4.4 for inquiry
