10.2 Active power regulation

10.2.1 Active power limitation

The function "P target value" is integrated into the MPP tracking of the inverter on all PV inverters. The
P target value is continuously re-calculated on the basis of the MPP tracking algorithm.
P limit
The function "P limit" is available for limiting the maximum feed-in power. If necessary, this can be
used to reduce the feed of an inverter, e.g. for managing bottlenecks for the operator of the distribution
grid.
P limit is only available via the MODBUS/SunSpec inverter model 123 WMaxLimPct and via RS485
communication. You can find detailed information on the communication protocol at
nergy.de in the "Software" subsection of the "Downloads" section.
When a target value is received for P limit, the output power of the inverter is limited to the specified
power value. If the limit value is changed, the new value is adopted by way of a filter and a gradient li-
mitation. The current power may be below the specified limit value because the available power (PV)
or the target power value (storage) may be below the specified limit value. Depending on the inverter
series, the settling time and gradient limitation may be adjustable.

Action in this menu/meaning
Voltage of the node in volts.
The voltage values of the nodes must increase continuously. At voltages
below the 1st node and voltages above the last node, the reactive po-
wer value of the 1st or last node is used each time.
Reactive power of the node as a percentage of the maximum power
Reactive power mode Under-excited relates to inductive load, over-exci-
ted relates to capacitive load.

ce
Specifies the standard power in the event of
a communication failure. If no active power
command is received within the configured
timeout, the inverter sets the power to the
configured fallback power.
Specifies the timeout time after which the
inverter sets the fallback power in the event
of a communication failure.
The gradient limitation is deactivated.
