"PV 1" and "PV 2"
Parameter Value range Description
"Mode" Off The MPP tracker is deactivated.
Auto The inverter uses the voltage at which the
max. possible output of the MPP tracker is
possible.
Fixed The MPP tracker uses the voltage defined
in "UDC fixed".
"UDC fixed" 80 ‑ 530 V The inverter uses the fixed voltage that is
used on the MPP tracker.
"Dynamic Peak
Manager"
Off Function is deactivated.
On The entire solar module string is checked
for optimization potential and determines
the best possible voltage for the supply of
energy from the inverter into the grid.
On (MLSD) The entire solar module string is checked
for optimization. The inverter can commu-
nicates with module level shutdown
devices (MLSD).
"Ripple control signal"
Ripple control signals are signals that are sent by the energy company in order to
switch controllable loads on and off. Depending on the installation situation,
ripple control signals can be dampened or amplified by the inverter. This can be
counteracted if necessary by applying the following settings.
Parameter Value range Description
"Reduction of
influence"
Off Function is deactivated.
On Function is activated.
"Frequency of
the ripple con-
trol signal"
100 ‑ 3000 Hz The frequency specified by the energy
company must be entered here.
"Grid induct-
ance"
0.00001 ‑ 0.00
5 H
The value measured at the infeed point
must be entered here.
"Measures to prevent FI/RCMU false alarms"
(when using a 30 mA residual current circuit breaker)
NOTE!
A residual current circuit breaker for the AC connecting cable may be required
depending on national regulations, the grid operator, and other conditions.
A type A residual current circuit breaker is generally sufficient in this case. Nev-
ertheless, false alarms can be triggered for the type A residual current circuit
breaker in individual cases and depending on local conditions. For this reason,
Fronius recommends using a residual current circuit breaker suitable for fre-
quency inverters with a release current of least 100 mA, taking into account na-
tional provisions.
