10.4.2 Soft start up / power ramp-up limiting
A soft start-up function is available to prevent the grid from being negatively impacted by a sudden increase in feed-in
power from the inverters.
When the inverter is activated or switched on, the increase in power is restricted by the set gradient. It is possible to con-
figure whether the soft start-up should occur every time the device is switched on, only upon initial start-up each day or
only upon start-up after the device has been switched off by grid protection. Due primarily to the fact that there is the
risk that many plants could increase their power levels simultaneously after they have been switched off by grid protec-
tion, a soft start-up is usually only required for start-up after a device has been switched off by grid protection.
The soft start up is implemented by an absolute power limitation that increases with a continuous gradient up to the
maximum power. The actual power of the inverter may vary freely below this limit due to a possible fluctuation in the
available power or the target value, but at no time increases above the absolute power limit.

10.4.3 Normal operation power gradient
In the case of very large plants, it may also be necessary to restrict the change in power level during normal operation. If
the set value (for increase and decrease in power level) and the solar irradiation change (for increase in power level), then
the grid feed-in power is increased or decreased in line with the configured gradient. A limitation is not possible if the so-
lar irradiation is reduced.
This function isn't active for changes in the power, which are defined by another grid support action such as the return of
power after Fault Ride Through, P(f), P(U).

Soft start ramp up is activated for every connection of the inverter to

Soft start ramp up is activated for the first connection of the inverter to
the grid on a particular day or after complete reboot of the inverter (AC
and DC disconnected).
Soft start ramp up is activated for connection of the inverter to the grid
after trip of the internal interface protection or via the external grid pro-
tection port (Powador-protect)
