Installation Manual
8.3 Preparation for Starting
When all the foregoing items are inspected and comply with the requirements, prepare to
start the device.
Place the disassembled protection grills to their original positions and ensure the
connection is secure.
Close and lock the cabinet door.
Clean the device site. Make sure the position is clean without inflammable or explosive
materials.
Ensure the ventilation of the installation place.
Recheck and ensure inverter and switches upstream and downstream meet the
requirements and flexible enough.
8.4 Starting
If all tests and measurements have been performed, and all measured values lie within the
permissible range, the device can be switched on for the first time. Proceed as follows to
start the inverter:
Step 1
Open the inverter Ac cabinet door; turn the AC switches to "ON" position; and lock the AC
cabinet door.
Close the switches of all inverter upstream combiner boxes.
Step 2
Open the DC cabinet door; turn the DC switches to "ON" position; and lock the DC cabinet
Step 3
door (close all the 16 DC switches even if there are less than 16 DC inputs) and wait about
1 minute.
Turn the Start/Stop switch to the "START" position to start the inverter.
Step 4
It will take about 1 minute for the auto-initialization of both the power conversion circuit and
Step 5
the LCD panel. The POWER LED indicator is on.
If the DC voltage falls below the DC start-up voltage, the state in the LCD display will be in
Step 6
Start-up.
If the DC voltage exceeds the DC start-up voltage for about 1 minute, the inverter will

automatically change to "RUN" mode. The OPERATION indicator will be on, and the
inverter starts running.
To ensure the inverter normal operation for the first time, please measure the
inverter DC input voltage beforehand. When the DC side voltage meets the
start-up requirement, i.e. DC voltage is steadily higher than DC start-up voltage.
Start the inverter for the first time.
8.5 LCD Parameter Setting
When the LCD is on, set the display language, data and time, communication parameters,
active power limitation, etc. according to the Operation Manual. You can also view the
inverter running information and perform related operation via the LCD.
