Description of the LED function
The LED functions on the inverter are described below.
POWER
Indicates that the inverter is functioning correctly.
When the unit is commissioned, while the grid is checked, this LED
blinks. If a valid grid voltage is detected, the LED remains continuously
lit, as long as there is sufcient sunlight to activate the unit. Otherwise,
the LED will continue to blink until the sunlight is sufcient for activation.
ALARM
Indicates that the inverter has detected an anomaly. This type of problem
is highlighted in the Web User Interface and ABB Installer for Solar
Inverters APP.
GFI
The “GFI” (ground fault) LED indicates that the inverter has detected
a ground fault in the DC side photovoltaic generator. When this fault is
detected, the inverter immediately disconnects from the grid.
COMM. (WI-FI/ETHERNET)
Indicates the status of the WI-FI or ETHERNET communication lines.
The LEDs, in various multiple available combinations, can signal multiple conditions other
than the original single condition; see the various descriptions explained in the software
manual.
