7.4 Preparation before Starting
•
Place the disassembled protection grills to their original positions and ensure the
connection is secure.
•
Clean the device site. Make sure the position is clean without flammable or explosive
materials.
•
Ensure the ventilation of the installation place.
•
Recheck to ensure the inverter and switches upstream and downstream meet the
requirements and are flexible enough.
7.5 Starting the Device
If all tests and measurements have been performed, and all measured values lie within
the acceptable range, the device can be switched on for the first time. Proceed as
follows to start the inverter:
step 1 Close the upstream and downstream switches of the inverter.
step 2 Close the AC and DC maintenance switches.
step 3 Stop the inverter through the touch screen.
step 4 Manually close all DC switches inside the DC cabinet.
step 5 Perform the start operation through the touch screen, and the inverter starts grid-
connected operation.

To ensure the inverter operates normally for the first time, measure the DC
input voltage beforehand. When the DC side voltage meets the start-up
requirement, i.e., the DC voltage is steadily higher than the DC start-up voltage,
start the inverter for the first time.
7.6 LCD Parameter Setting
When the LCD is on, set the LCD display language, date and time, communication
parameters, and active power limitation, etc. You can also view the inverter running
information and perform pertinent operation.
7.7 Completing Commissioning
If all the start-up procedures have been performed, check the operating condition of the
inverter.
•
Check whether there are anomalies of the inverter: abnormal noise, overheating,
smoking, or unusual odor.
