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
power value of the 1st or last node is used each time.
1 – 0.3 Reactive power of the node as a percentage of the maximum power
Over-excited | under-
excited Reactive power mode Under-excited relates to inductive load, over-ex-
cited relates to capacitive load.
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 www.kaco-newenergy.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 limitation. The current power may be be-
low the specified limit value because the available power (PV) or the target power value (storage) may be below the spe-
cified limit value. Depending on the inverter series, the settling time and gradient limitation may be adjustable.
Parameters Setting Reference Description
Power Limitation
[
WMaxLimPct
]
0 – 100 [%] Specifies the standard power in the event of a
communication failure. If no active power com-
mand is received within the configured timeout,
the inverter sets the power to the configured
fallback power.
Timeout
[
WMaxLimPct_RvrtTms]
3 – 100000 [%] Specifies the timeout time after which the in-
verter sets the fallback power in the event of a
communication failure.

Limitation of power gradients
The power reduction parameters can be adjusted in SunSpec model DID123. During this process, you should also check
whether internal and/or external power reduction is active.
