The following table shows all the possible activation combinations of “Power” “Alarm” and “GFI” LEDs on the
LED panel
(08)
according to the operating status of the inverter.
Led Status
Operating state
green:
yellow:
red:
Firmware programming
The inverter firmware is being programmed (never turn off the inverter during this phase).
green:
yellow:
red:
Night mode (inverter automatically switches off)
The inverter is in night time switch-off mode (input voltage less than 70% of the set
start-up voltage and AC grid is missing).
green:
yellow:
red:
Inverter initialization / Waiting Sun
This is a transitional state due to verification of the operating conditions. During this
stage the inverter checks that the conditions for connecting to the grid are met.
green:
yellow:
red:
The inverter is connected and is feeding power into the grid
Normal operation. During this stage, the inverter automatically tracks and analyses the
photovoltaic generator’s maximum power point (MPP).
green:
yellow:
red:
Missing grid
Indicates lack of grid voltage. This condition does not allow the inverter to connect to the
grid.
green:
yellow:
red:
Warning indication: (W message codes) or Error: (E message codes)
- Indicates that the inverter control system has detected a warning (W) or error (E). It is
possible to identify the type of problem generated in the dedicated section of integrated
Web User Interface (“Inverter Log” section).
green:
yellow:
red:
Temperature protection trip
Indicates that the trip relating to internal temperatures (insufficient or excessive
temperature) may have been activated.
green:
yellow:
red:
Ventilation anomaly
Indicates ananomaly in the operation of the internal ventilation system that could limit
output power at high ambient 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
Self-test not carried out (for Italian grid standards only)
Self-test operation failure
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.
