Operation 85
The operating modes of the PVS300 string inverter
Operating status Example graphical display Description
Sleep This is a low power consumption mode in
which only essential electronics use
power. The inverter enters sleep mode
when the DC input voltage is below a
threshold value and there is no control
unit activity during the threshold time
period. The power meter shows “-- kW”
when the inverter is going to sleep.
Stand-by From sleep mode, the inverter switches
to stand-by mode if the DC voltage rises
above the threshold value or if there is
control unit activity (wake up call by the
user).
In stand-by mode, the inverter performs
continuous monitoring and the testing
required for safe grid connection.
The power meter shows “-- kW” when the
inverter is on stand-by.
Note: During stand-by operation the
inverter can draw power from the solar
array or the electrical grid.
Normal operation The inverter has established a grid
connection. The solar array is producing
adequate electrical power which is being
fed to the grid. The rays of the sun
symbol are used to show the current
output power level Check output view of
the control unit. The power meter shows
the output power in the form “x.xx kW”
when the inverter is in normal operation.
Limited operation
Note: Like Normal operation
but less of the sun symbol’s
rays are filled.
The inverter is operating with a limited
power output. Check events from the
control unit. The power meter shows the
output power in the form “x.xx kW” when
the inverter is in limited operation.
The control unit’s LED flashes green
during limited operation.
