General information
7.1 Why active power control?
Some countries or energy supply companies stipulate
that the full power of the PV system must not be
supplied to the public grid (e.g. by limiting it to just 70%).
In this case, some energy supply companies therefore
offer the owners of PV systems the possibility of
regulating their system with variable active power
control, and thus raising the feed-in to up to 100% again.
Ask your energy supply company what application rule
applies to you.
The planner of a PV system can choose between two
types of active power control:
n
Limitation of the feed-in capacity to a defined
percentage of the PV power at the grid connection
point
n
Active power control with a ripple control receiver by
the energy supply company
INFO
When selecting active power control,
check to determine which of the two
possibilities offers the better energy
yield.
