Commissioning

6.1 Commission the Inverter

1) Remove all covers from the PV array.
2) Check the PV and AC voltage.
3) Plug in the PV input.
4) Turn the DC Disconnect to position "I".
5) If the inverter is connected with PV panel arrays and the input voltage is higher
than 160Vdc, while the AC grid is not connected yet, LCD will display messages in
order as below:
Company info Basic info
The LCD will display " AC V outrange "at State info and the LED turns red.
Please check all information on the LCD, operate by knocks you will see the
different parameters.
Single knock to Light the backlight
(single knock) Output info
6) Turn on the AC breaker between inverter and grid, the
system will operate automatically.
7) Under normal operating conditions, the LCD displays
'Power: xx.xx Kw' at State info, this is the power feed into
grid. The LED turns green.
8) Check the time and date of inverter as follow:
Single knock to Light the backlight
knock)
knock), if they are not correct, please set them, refer to
6.3.5 setting inverter time and date.
9) Finish commissioning.

6.2 Operation Modes

Normal Mode
In this mode, the inverter works normally and LED turns green.
Whenever the DC voltage is higher than 200Vdc, inverter converts power to grid
Whenever the DC voltage is lower than 180Vdc, the inverter will work in waiting
status and attempt to connect the grid. In waiting state the inverter consumes
just power generated by the PV panel to monitor the internal system.
Notes: The inverter starts up automatically when DC power from the PV panel is
sufficient.
Fault Mode
The internal intelligent controller can continuously monitor and adjust the system
status. If inverter finds any unexpected conditions such as system fault and inverter
fault, the fault information will be displayed on the LCD. In fault mode the LED turns
red.
Notes: a) Detailed fault information refers to Chapter 9 Trouble shooting.
b) When PV Isolation error occurred in SAA safety standard, the buzzer will
give an alarm every fifteen seconds.

Shutdown Mode
Inverters automatically stop running during periods of little or no sunlight. In
shutdown mode the inverters take no power from the grid and panel, and the LCD
and LED turns off.
Notes: If the PV string DC voltage is too low, the inverter will also turn to Shutdown
Mode.
Derating mode
When AC frequency is higher than 50.3Hz(settable), the inverter will derate its
output power according to the rule.
When user set the output limit command to the inverter, the inverter will also limit
the output according to the setting.
In this derating mode, the LCD will show "DERATING".
6.3 Country Setting and LCD Display
In the lower right corner of inverter there is the LCD display. We can check inverter
running state, historical generation data, etc, on the LCD screen. Items displayed can
be changed by knock; you can also change some inverter parameters by knock.
6.3.1 Location of the country setting DIP switch
The DIP switch is located on the left of the RS232 interface at the bottom of the
inverter, as the figure below.
Country setting DIP switch
To reduce the risk of electric shock, before selecting country, please turn
off DC input and AC grid, than unscrew the dam-board of the DIP switch
by appropriate tool.
