Symbol Cause
A setting has failed because it was not trans-
ferred correctly.
–
The network carries no voltage (inverter
stand-alone operation).
–
For safety reasons, the inverter must not
feed into the network.
The inverter switches off while the fault
is present (display is dark).
The functional earth is not connected.
For safety reasons, the inverter must not
feed into the network.
The residual current that flows from the plus
or minus input via the PV generators to earth
exceeds the permitted value.
Due to legal regulations, the inverter
automatically switches off while the fault is
present.
An internal component in the inverter is
defective.
The inverter does not feed into the network
or feeds in with reduced power.
Despite the reduction in output, the max-
imum permissible temperature has been
exceeded.
The inverter does not feed into the network
until the permissible temperature range has
been reached.
The inverter cannot detect an internal com-
ponent or it does not match the other com-
ponents.
The inverter does not feed into the network.
The connection for the internal components
has been interrupted.
The inverter does not feed into the network.

Measure
Implement the setting again.
Check the alternating current installation
(utility connection):
–
Check the circuit breaker (fuse) and, if
required, switch it on.
–
Check the residual-current circuit
breaker and, if required, switch it on.
–
Replace the defective switch.
–
Ensure that the alternating current in-
stallation (utility connection) is working.
–
Ensure that the protective conductor is
connected correctly.
–
Ensure that none of the direct current
cables are earthed.
–
Ensure that only suitable photovoltaic
modules are used.
–
Ensure that the direct current installation
is working.
–
Use a suitable analyser to ensure that
the photovoltaic generator is working
correctly.
