Status Display Explanation Action
FS 58 Overtemperature
Control card
The temperature inside the unit was
too high. The inverter switches off to
prevent damage to the hardware.
 Provide for suffi cient
ventilation.
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 Associa-
tion 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 70 Fan error The fan is malfunctioning.  Replace
defective fan
E
OS 74 External idle power
requirement
The grid operator limits the feed-in
power of the inverter.
- -
FS 78 Resid. current shut-
down (AFI)
The integrated AC/DC-sensitive
residual current device registered an
non-permissibly high leakage cur-
rent going to PE.
 In case of repeated
occurrence:
Notify your author-
ised electrician.

urement
PV generator’s insulation is being
measured

Protection shut-
down line volt.
L1 L2, L3
Overvoltage has been detected on
a conductor. An internal protective
mechanism has disconnected the
device to protect it against damage.
 In case of repeated
occurrence:
Notify your author-
ised electrician.
E
FS 84 Protection shut-
down undervolt.
DC link
A voltage deviation has been found
in the DC link. An internal protective
mechanism has disconnected the
device to protect it against damage.
 In case of repeated
occurrence:
Notify your author-
ised electrician.

overcurrent L1
A current that has been found on a
conductor is too high. An internal
protective mechanism has dis-
connected the device to protect it
against damage.
 In case of repeated
occurrence:
Notify your author-
ised electrician.

Too much power has been fed into
the grid. Complete disconnection of
the device.

FS 100 Protect. shutdown
HW overheating
The device has been switched off
because the temperatures in the
housing were too high.
 Check to make sure
that the fans are
working.
 Replace fan if nec-
essary.
