Generator overcurrent error
1
The DC current has exceeded the permissible
maximum value on PVx. A shutdown is carried
out to protect the device.
How much gener-
ator power is con-
nected? The risk of
a shutdown is
higher if the oversiz-
ing is excessive and
the PV voltage is
lower.

Check ground fault fuse
DC side ground fault A ground fault was detec-
ted on the DC side. There is the option of
switching this on in all country versions via a
display entry. Ground fault monitoring is al-
ways active in the USA.
Check the solar gen-
erator for an inad-
missible ground
fault.
E
30
Voltage trans. fault
Current and voltage measurement in the
device are not plausible.
Switch off the
device entirely
(switch off AC + DC
for min. 5 minutes),
if the fault occurs
again, contact the
service department
B
31
AFI module fault
Current offset during automatic offset adjust-
ment too great.
Disconnect the
device from the AC
and DC supply.
Switch it back on
after several
minutes. If this does
not resolve the is-
sue, notify your au-
thorized electrician
B E
32
Self test error
The internal grid separation relay test has
failed.
Notify your author-
ized electrician if
the fault occurs re-
peatedly!
E
33
DC feed-in error
The DC feed-in has exceeded the permitted
value. This DC feed-in can be caused in the
device by grid conditions and may not neces-
sarily indicate a fault.
E
34
Internal communication er-
ror
A communication error has occurred in the in-
ternal data transmission.
Contact a qualified
electrician! Check
the data cable.
E
35
Protection shutdown SW
Protective shutdown of the software (AC over-
voltage, AC overcurrent, DC link overvoltage,
DC overcurrent, DC overtemperature).
Not an error! Grid-
related shutdown,
the grid connects
again automatically.
-
36
Protection shutdown HW
Group error for all trip zone shutdowns, gener-
ally the precise shutdown reason appears first,
followed by this group error.
Cause: Saturation monitoring of the AC IGBTs
or AC overcurrent. Protective shutdown when
critical limits are exceeded, hardware.
Not an error! Grid-
related shutdown,
the grid connects
again automatically.
