CDP
10 Application notes
The most important inverter parameters that have to be configured in the CDP are
( Table 4 ):
Table 4: Parameters to be configured in the CDP .
Parameter Description
Inverter type Inverter model. In this case select: DELTA
Inverter power
Total power to be controlled by the CDP.
Number of inverters
Number of inverters to control.
Phase
Architecture of the inverter connections
Consult the manual for more information on how to configure
the CDP.
When working with several three-phase inverters in cascade, the sum of the
power of all the inverters must be programmed in the
Inverter Power variable in
the CDP so that the same regulation percentage is sent to each one.
When working with single-phase inverters in three-phase installations, the total
power of all the inverters must be programmed by selecting the "
three single
phases " option in the " Phase " variable, and then entering the number of sets of
three single-phase inverters in the installation in the " Number of inverters "
variable.
Example : If there are six 2 kW single-phase inverters (two on the L1 phase, two
on the L2 phase and two on the L3 phase) the following configuration should be
entered:
•
Inverter power: 12000 W
•
Number of inverters: 2
•
Phase: three single phases
However, if there are three 2 kW single-phase inverters (one inverter per phase)
the following configuration should be entered:
•
Inverter power: 6000 W
•
Number of inverters : 1
•
Phase: three single phases
