Status Display Explanation Action
FS 49 Line failure:
Over frequency
Grid frequency is too high.
This fault may be grid-related.  Notify your
authorised
electrician.
E
FS 50 Line failure:
average voltage
The grid voltage measurement
according to EN 50160 has exceeded
the maximum permitted limit value.
This fault may be grid-related.  Notify your
authorised
electrician.
E
FS 57 Waiting for
reactivation
Waiting time of the inverter after a
fault. Inverter does not switch
on again until the country-
specifi c time has elapsed.
FS 58 Control board
overtemperature
The temperature inside the unit was
too high. The inverter switches off to
prevent damage to the hardware.  Provide for
suffi cient
ventilation.
E
FS 59 Self test error A fault occurred during a self-test.  Notify your
authorised
electrician.
E
OS 60 Generator voltage
too high The inverter does not begin feeding
into the grid until the PV voltage falls
below a specifi ed value. - -
OS 61 External
limit (%) The external limit Power control was activated by the grid operator.
The inverter limits its power.
OS 63 Measured values P(f)/frequency-dependent power reduction: Frequency-dependent
power reduction will be activated when the BDEW (German
Association of Energy and Water Industries) Medium Voltage Directive
goes into eff ect. Power reduction starts at a frequency of 50.2 Hz.
OS 64 Measured values Output current limiting: The AC current is limited once the specifi ed
maximum value has been reached.
FS 67 Fault at power
section 1 There is a fault in the power section.  Notify your
authorised
electrician.
E
FS 70 Fan error Fan 1 is malfunctioning.  Replace
defective fan
E
FS 73 Standalone grid err. Standalone mode was detected. - -
OS 74 External idle power
requirement The grid operator limits the feed-in
power of the inverter. - -
OS 79 Insulation
measurement PV generator’s insulation is being
measured - -
FS 80 Insulation meas.
not possible The insulation measurement cannot
be performed because the generator
voltage is too volatile. - -
