(3) Use of the display

There are 2 modes of button operation: Short press and long press.

(4) Use of the display and LCD display

The display allows accessing the configuration of the basic parameters. All the language, time and country settings can be

configured by buttons. The menu, shown in the LCD display area has two levels of menu. Short and long key presses will take you

between menus and through each menu. Items in the first level menu that have no second level are locked. For these items, when

the key is pressed for two seconds, the LCD will display the word "Lock" followed by data relating to the first level menu item. The

locked menu can only be unlocked under system mode switching, fault occurrence or key operation.

In all levels of menu, if no action is taken for 20 seconds, the backlight of the LCD display will switch off, the display will

automatically revert to the first item of the first level menu, and any modifications made to the data will be stored into internal

memory.

(5) Menu Introduction

●When the PV panel is feeding power to the inverter, the screen shows the first-level menu.

● The initial display is the first item of the first level menu, and the interface displays the current status of the system. It shows

"Waiting" in the initial state; it shows "Normal" during power generation mode; if there is something wrong with the system, an

error message is shown. Please refer to chapter 5.

View PV voltage, PV current, grid voltage, current and frequency:

●Short press the key to enter the E-Today menu which displays the total power generation for today.

●Short press the key to enter the E-Today menu which displays The total power generation Until today.

●Short press the key to enter the Vpv menu which displays the PV voltage in "V".

●Short press the key to enter the Ipv menu which displays the PV current in "A".

●Short press the key to enter the Vac menu which displays the grid voltage in "V".

●Short press the key once more to enter the Iac menu which displays the grid current in "A".

●Short press the key once more to enter the Frequency menu which displays the grid frequency in "Hz".

●View Error code

Short press the key once more to enter the Error Code History menu.

Long press (2S) the key to enter the second level menu of error detection. The last three inverter error records will be shown by

short pressing the key in this second level menu. The records include error codes (EXX) and error times (110316 15:30). Error codes

and their related faults can be found in Table 4.3.

●View model name and reconfigure safety country:

From the error code history item in the first level menu, short press the key once to see model name.

If you want to change the safety country, please hold the key for 2 seconds, then the LCD screen will go to the second level menu.

In the second level menu, short press the key can change the safety country.

After choosing the suitable safety country ,the inverter will store the chosen the safety country if no operation within 20 seconds.

If there is no EXACTLY proper country code, please choose '50Hz Grid Default' or '60Hz Grid Default' accordingly.

●View software version

From the model name item in the first level menu, short press the key once to see software version.

The current software version can be shown in this menu.

Settings:

●Set language:

Short press the button to enter the Set Language menu. Long press (2S) the key to enter the second level menu. Short press to

browse the languages available. The inverter will store the chosen language after 20 seconds of no operation.

●Set time:

From the first level Set Language menu, short press the key to enter the Set Time menu.

Long press (2S) the key to enter the second level menu. The initial display is "2000-00-00 00:00", in which the first four numbers

represent the year (e.g. 2000~2099); the fifth and sixth numbers represent the month (e.g. 01~12); the seventh and the eighth

numbers represent the date (e.g. 01~31). The remaining numbers represent the time.

Short press to increase the number in current location, and long press to move the cursor to next position. The inverter will store

the time after 20 seconds without any key operation, and the LCD will automatically return to the main menu and the backlight

will switch off.

●Set protocol:

The function is only used for service personnel, set wrong protocol could lead to communication failure.

From the first level Set Time menu, short press the key once to enters set protocol display menu. Press the key for 2S to enter

submenu. The circulatory submenu including two protocols can be found. The protocol can be chosen by short pressing the key. The

inverter will store the chosen protocol without any action within 25S and LCD display will automatically return to main menu when

the backlight is off.

●MPPT function for Shadow:

The default setting for shadow optimizer is disabled.

Please enable shadow optimizer when there is shadow on PV panel. The function could help the system generate more power

under shadow condition.

Please do not enable the function when there's no shadow on panel. Otherwise it could lead to generate less power.

Press the key until enter Shadow Optimize menu. When it shows "Shadow MPPT OFF", it means the MPPT function for shadow is

switched off. Press the key 2S to enable the function. If it shows "Shadow MPPT ON" it means the shadow optimizer is on. Press

the key 2S to disable the function.

●70% Rated power limit.

The function could only be available for inverter in German. It could only be used by network operator. Otherwise it will cause the

PV plant generated reduced.

Press the key until enter 70% rated power menu. If it shows "70% Rated Enable" it means the function to limit the inverter

working under 70% rated output is switched off. Pressing key 2S will switch this function on. If it shows "Recover Rated Power" it

means inverter is working under 70% of rated output power. Press key 2S will recover inverter to 100% of its rated output power.

(6) Power limiting function setting

The Operations that the ON/OFF of power limiting function (the default is OFF) and the power limiting settings (the default is 2%

Rated) are shown below:

Note： If the power limiting function is ON, the maximum output power of the inverter will be limited at the power limiting setting

value while the inverter is without the power limiting device(such as a CT/Meter ) or the power limiting device is out of work.

(7) Operation of Display when commissioning.

When the input voltage reaches the inverter turn-on voltage, the LCD starts to work, the yellow light is on and the LCD displays

"Waiting". More information will be displayed within a few seconds. If the inverter is connected to the grid, "Checking 30" will be

displayed and a countdown will commence from 30 seconds. When it shows "00S" you will hear the relay triggered 4 times. The

LCD will then display "Normal". The instant power output will be shown at the left bottom of the LCD.

4.3 Error code

An error message will be displayed on the LCD if a fault occurs.
