5.6 Status messages

The following table shows the possible status messages, subdivided into four cat-
egories:
Startup Irradiance too low
LED: Flashing
(green)
Startup...
Restart in...s
Mains operation MPP operation
LED: Green
Maximum power
Mains operation
Idc limitation
Iac limitation
83
The solar irradiation is too low; feed
mode is not possible
In this state the inverter checks all
requirements that must be satisfi ed in
order to enable secure feed mode
After a shutdown this value indicates
the number of seconds after which
feed mode will resume
The inverter has found the operating
point of the solar generator with the
maximum inverter output
The inverter limits the output to the
maximum power of the device (this
may happen if the solar generator is
oversized)
The inverter is connected to the mains
and is operating in feed mode
The inverter limits the solar generator
current to the maximum permissible
value (this may occur if the solar
generator is designed such that the
current at MPP exceeds the maxi-
mum permissible input current of the
inverter)
The inverter limits the mains current
to the maximum permissible value
(this may occur in the event of strong
irradiance fl uctuations or if the solar
generator is oversized)
Vdc too high
Malfunction
LED: Orange
Iac asymmetric
Ierr too high
No mains
Frequency too high
Frequency too low
Mains error
Bad mains quality
Vac too high
Vac too low
Temp. too high
Insulation fault
Fault Device error
LED: Flashing (red)
Overvoltage
Overcurrent
The solar generator voltage is too
high
The DC component of the mains cur-
rent is too high
A fault current in excess of the
permissible limit value has occurred
on the solar generator side
No mains voltage
The mains frequency is too high
The mains frequency is too low
A mains fault was detected
The 10-minutes mean value of
the mains voltage exceeds the
permissible limit value (according to
VDE0126-1-1)
The mains voltage is too high
The mains voltage is too low
The inverter has interrupted the feed
mode because the heat sink tempera-
ture exceeds 80 °C
(see also section 3.7)
An insulation fault was detected in
the solar generator or in the wiring of
the solar generator.
An internal inverter fault has
occurred
The DC link voltage of the inverter is
too high.
An overcurrent has occurred in the
inverter
