Operating modes
Mode Example view Description
Sleep A low power mode with only essential
functions. The inverter starts the sleep mode
when the DC input voltage is less than the
threshold value and there is no control unit
activity. The power meter shows “-- kW”.
Stand-by From the sleep mode, the inverter goes to
the stand-by mode when the DC voltage
increases to more than the threshold value
or when there is control unit activity.
In the stand-by mode, the inverter monitors
the grid connection. The power meter shows
“-- kW”.
In the stand-by mode, the inverter can draw
power from the PV array or electrical grid.
Normal
operation
The inverter operates and feeds electrical
power to the grid.
The sun symbol shows the current output
power, e.g. 80% (with 8 out of ten rays).
The power meter shows the output power as
“#.## kW”.
Warning A warning has been triggered.
Normal operation continues automatically if
the cause of the warning is temporary, for
example, if there’s a temporary power
outage.
Read the warning events from the control
unit.
The power meter shows “-- kW”.
Fault A fault has occurred.
The inverter goes into the stand-by mode
and user action is needed to start normal
operation.
Read the fault events from the control unit.
The power meter shows “-- kW”.
