Parameter
"Ramp-Down Irra-
diation"
Note: This func-
tion only has an
effect on invert-
ers with storage.
"Ramp-Down Irra-
diation Rate"
Example: Effective power limitation by "Irradiation-Ramp-Up/Down", which was
caused by a change in the available PV power.
"Ramp-Up/Down Communication"
This is a limitation of the effective power rate of change when changing external
specifications for effective power. These can be, for example, power limitations
via I/Os or Modbus commands. If smaller rates of change are specified via Mod-
bus command, these are applied, larger rates as "Ramp-Up Communication Rate"
or "Ramp-Down Communication Rate" are limited with the same.

Range of values Description
On The effective power reduction is limited
with a rate of change of "Ramp-Down
Irradiation Rate".
Off The function is deactivated.
0.001 - 200 Permitted rate of change of effective
[%/s] power.
Range of values Description
On The limitation of the rate of change
(corresponding to "Ramp-Up Commu-
nication Rate") in case of effective
power increase due to an external spe-
cification is activated.
Off The function is deactivated.
0.001 ‑ 100
Permitted rate of change during power
[%/s] increase.
On The limitation of the rate of change
(corresponding to "Ramp-Down Com-
munication Rate") in the event of ef-
fective power reduction due to an ex-
ternal specification is activated.
Off The function is deactivated.
