Explanation
Message indicates regular feed-in mode.
If irradiation is sufficient, MPP controls
are used for feed-in to gain maximum
yield.
During the self-test before grid feed-in,
the following sequence is run through:
1. S8 grid relay self-test
2. S79 ISO measurement
3. S8 filter relay self-test
4. S75 (load DC link)
5. S8 pre-synchronization
6. S4 feed-in
The device was switched off due to over-
heating caused by lack of air circulation.
Power limitation: If the generator power
is too high, the device limits itself to the
maximum power (e.g. around noon if the
PV generator capacity is too large).
Due to a grid fault (e.g. under/overvolt-
age or under/overfrequency), a shutdown
has been initiated by the higher level grid
system protection. Set limit value was ex-
ceeded.
The integrated all-current sensitive resid-
ual current circuit breaker has registered
an impermissibly high leakage current to
PE. Tripped with a jump of 30mA, 60mA
& 150mA each with the corresponding
shutdown times. The reconnection time
is country-specific.
Internal power limitation e.g.: "Ramp Up"
10 %/min The result when the power is
increased with a ramp is country-specific
(after P(f), restart, after grid error, after
every connect)
A fault has occurred in the all-current
sensitive residual current circuit breaker.

Manual
Remedy
Is the expected power not fed in? =>
Check open no-load voltage with multi-
meter and check PV system if: - DC polar-
ity reversal is present
- frequent power limitation due to under-
sizing
- if constant voltage operation is active:
check if no-load voltage is less than set
constant voltage.
The events from the self-test can indicate
the cause on the PV system or device.
Observe the last displayed status.
Were the minimum clearances for instal-
lation on the other side observed? =>
Check information in chapter 6.
Was the device accidentally covered?
=>Remove object or cool off the area.
Is the fan or, if accessible, the heat sink
contaminated? => Clean fan & heat sink
according to chapter 11.2.
see Status 8 in Remedy
> Has the grid plant protection been sup-
plied with power correctly? => Check the
"grid parameters" on the grid plant pro-
tection. (external device)
> Is the cabling routed correctly?
=> If external grid plant protection is not
needed, it must be deactivated in the
menu of the device. See chapter 9.4
"Menu structure".
> Was the PE cable routed correctly or
does this fault occur frequently when it
rains? => Measure the insulation resis-
tance of the system and ground the PE
cable correctly, if necessary.
This is required in the country-specific
standard.
