Parameter Range of val-
ues
Description Availability
"Power at Stop
Frequency - Un-
derfrequency"
0 ‑ 100 [%] Power when the set fre-
quency limit value "Stop
Frequency - Underfre-
quency" is reached. Ad-
justable between 0 % and
full feed-in power (100 %).
"Upper Deactiv-
ation Threshold
Underfre-
quency"
45 ‑ 66 [Hz] Used when "Mode" is set to
"On (with Hysteresis)".
If this value is greater than
the "Lower Deactivation
Threshold Underfre-
quency", there is a fre-
quency window in which
the grid frequency must
be to terminate the func-
tion. If this value is less
than or equal to the
"Lower Deactivation
Threshold Underfre-
quency", it is not applied.
"Lower Deactiv-
ation Threshold
Underfre-
quency"
45 ‑ 66 [Hz] In use when "Mode" - "On
(with Hysteresis)" is set.
If the grid frequency ex-
ceeds this value, the func-
tion is terminated, taking
into account the settings
under "Frequency-de-
pendent Power Control -
General".
"Transition Fre-
quency at Un-
derfrequency"
45 ‑ 66 [Hz] Frequency at which the
device with active battery
reaches an output power
of 0 W (charging power is
reduced). If the grid fre-
quency continues to drop,
additional energy is re-
leased into the grid. This
energy can come from the
PV generator or from the
battery. If there is no bat-
tery in the system or it is
not active, this parameter
has no function (behaviour
as in example 3 - underfre-
quency).
