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 pos-
sible to configure 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 protection, 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 fluc-
tuation in the available power or the target value, but at no time increases above the absolute power limit.
