Max. change in power in %:
A jerky reduction or increase in active power could have a negative impact on inverters in the long-term.
The "max. change in power" field is used to specify how high the maximum percentage change in power is
per period of time (15 seconds).
This value refers to the power reduction but is also used when starting up the plant after a power reduc-
tion.
