Displays the version and serial numbers of the PC boards in the inverter (e.g. for service
purposes)
Monitoring the grid:
GMTi - start-up time of inverter in s
GMTr - reconnection time in s following a grid fault
ULL - mean grid voltage over 10 minutes in V.
LLTrip - trip time for long-term voltage monitoring
Grid voltage limits:
UILmax - upper inner grid voltage in V
UILmin - lower inner grid voltage in V
Grid frequency limits:
FILmax - upper inner grid frequency in Hz
FILmin - lower inner grid frequency in Hz
Q-mode:
Current power factor setting cos phi
(e.g. Constant Cos(phi) / Constant Q / Q(U)-characteristic / etc.)
AC power limit:
Max. P AC - manual power reduction
AC voltage derating:
Status - ON / OFF voltage-dependent power reduction
GVDPRe - threshold from which the voltage-dependent power
reduction begins
GVDPRv - reduction gradient used to reduce the power, e.g.:
10% per volt above the GVDPRe threshold.
Message - activates the sending of an info message via Fronius
Solar Net
Fault Ride Through:
Status - default setting: OFF
If the function is activated, the inverter does not switch off im-
mediately in the event of a short-term AC voltage interruption
(outside of the limits specified by the grid supplier), but instead
continues to feed in power for a defined period.
DB min - default setting: 90%
"Dead Band Minimum" setting in percent
DB max - default setting: 120%
"Dead Band Maximum" setting in percent
k-Fac. - default setting: 0
