4.2.6 Setup of AC Operational parameters
Enter “1 SysPara” menu according to “6.3.7 System
protection parameter setup”.
(1) Check the AC voltage, frequency protection value
and time of protection actions.
(2) Change the parameters if necessary.
4.2.7 Setup of DC Operational parameters
(1) Check the PV start voltage and time of the inverter.
(2) Change the parameters if necessary.
4.2.8 Setup of operational parameters of MPPT
(1) Check the active derating and reactive
compensation of the inverter;
(2) Make changes if necessary.
(3) Set the active power derating to 10%.
4.2.9 Power supply from PV to inverter
(1) Turn off the AC circuit breaker.
(2) Turn on the DC circuit breaker to provide the PV
power supply to the DC side of the inverter.
(3) Check carefully whether there is abnormality,
including noise and smell.
(4) Turn off the DC circuit breaker if there is any
abnormality. Reconfirm whether the previous testing steps
are correct. Stop testing if no abnormality exists.
4.2.10 Self-check of power train
(1) Confirm that the front door of the inverter is closed
