isplay and keypad
There are three indicators on the LED panel and four buttons on the keypad. LEDs indicate
the operating state of the inverter. The keypad is used to review data in the two line display
area and access the data logged internally on the inverter, using the menus described in this
section.
LED Description
Green POWER
LED
Indicates that the inverter is working correctly.
This LED flashes while the grid is being checked during start up . If a valid grid voltage
is measured, the LED stays on continuously, provided there is sufficient sunlight to
activate the unit. If not, the LED continues to flash until there is sufficient sunlight for
activation. During this phase, the LCD shows the “Waiting for Sun” message.
Yellow ALARM
LED
Indicates that the inverter has detected an anomaly; the type of problem
is shown on the display area
b7.
Red GFI LED The GFI (ground fault indicator) LED indicates that the inverter has de-
tected a ground fault on the DC side of the PV array. When this fault is
detected, the inverter immediately disconnects from the grid and the rel-
evant error warning appears in the display area b7 .
Keypad button Description
ESC button Use the ESC button to access the main menus, exit a mode or go back.
UP button Use the UP button to read the data on the display by scrolling upwards, or to increase
the set value during data entry.
DOWN button Use the DOWN button to read the data on the display by scrolling downwards, or to
decrease the set value during data entry.
ENTER button Press ENTER to confirm the operation or to enter the set data item.
During operation, the display cycles through available data points, updating every five seconds. Screens may
be scrolled manually by pressing the UP and DOWN buttons on the keypad. Activation of cyclical scrolling will
be indicated by two arrows in the top left corner of the two-line display. Scrolling can be blocked by pressing
the ENTER key until a padlock symbol appears.
Some parameters (e.g., current, voltage, power, partial energy, lifetime energy etc.) are available only after grid
connection.
