4.4 WiFi Reset & WiFi Reload
The two functions are only available for WiFi model inverters.
WiFi reload function is used to change the WiFi configuration to default value. Please configure the WiFi again as 3.4.5 after using
the function.
Press the key until the LCD displays “WiFi Reset”, then long press (2S) until the LCD displays “WiFi Resetting…”. Stop pressing and
wait for the screen showing “WiFi Reset Successful” or “WiFi Reset Failed”.
Press the key until the LCD displays “WiFi Reload”, then long press (2S) until the LCD displays “WiFi Reloading…”. Stop pressing
and wait for the screen showing “WiFi Reload Successful” or “WiFi Reload Failed”.
●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 Optimized Off”, it means the MPPT function for shadow
is switched off. Press the key 2S to enable the function. If it shows “Shadow Optimized 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) 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.
