Operating and fault display

After the device is switched on, the system starts with a series of test procedures
which take a few seconds. When the output of the solar modules is high enough,
the inverter will switch to 'active mode'. When there is little irradiation it may be
that the solar modules do not produce enough power to feed the power grid. The
device then enters the standby mode.
The front of the control unit is equipped with a two-colour LED which shows the
operating status of the inverter. The LED shows the following operating states:
LED status System status
Green Active mode – nor-
mal operation
Green Standby mode

6.1 Fault messages

In addition to indicating the operating status the LEDs are also used to indicate
faults.
In the case of a fault (red LED display either constant or flashing) please notify
your installer immediately.
If a StecaGrid Vision display unit is used with the system then it can be used
for displaying error messages. Details on the error messages are provided in the
StecaGrid Vision manual.

the grid.
A fault is present but the inverter is still ca-
pable of full performance.
The inverter may no longer be capable of
full performance.
Contact your installer.
