LED status Operating state
green:
yellow:
red:
Ventilation anomaly
Indicates ananomaly in the operation of the internal ventilation system that could limit output power at high am-
bient temperatures.
Overvoltage surge arresters triggered (where fitted)
Indicates that any class II overvoltage surge arresters installed on the AC or DC side have been triggered
Internal statistics memory anomaly
Indicates an operating anomaly in the internal memory on which the inverter statistics are stored
Buffer battery discharged
The buffer battery is low and the inverter does not maintain the time setting
green:
yellow:
red:
Pre-commissioning phase (first start-up of inverter)
The commissioning of the inverter must be completed through the Installation wizard steps (Web User Interface)
or using the ABB Installer for Solar Inverters mobile APP
Initial configuration failure
The inverter is in locked state due to a failure in the initial configuration of the equipment, such as the standard
network setting for the country of installation
Incompatibility of the device firmware versions
The firmware versions of the various devices comprising the equipment are incompatible and are being updated
(this is an automatic operation)
Temperature sensor anomaly detected
green:
yellow:
red:
Remote OFF activated
The Remote Off command has been activated.
The unit will not connect to the network until the remote ON command has been activated
green:
yellow:
red:
Anomaly in the insulation system of the photovoltaic generator
Indicates that a leakage to earth from the PV generator has been detected, causing the inverter to disconnect
from the grid.
green:
yellow:
red:
DC arc fault detected during operation
If a DC arc fault is detected during operation, the inverter disconnects from AC grid (the error code is readable
through internal Webserver).
green:
yellow:
red:
AFD board self test failure
Potential problem on the AFD board detected during self test phase
The following table shows all the possible status of “WLAN/LAN” LED on the LED panel (08) according to the operating status of
the wireless or ethernet communication lines.
LED status Operating state
Blue: Wireless not configured or/and ethernet cable not connected.
