1.- INTRODUCTION

HUAWEI has several models of inverter that can be managed by the Dynamic
Power Controller (called CDP from its acronym in Spanish).
For the CDP to correctly manage the inverter, both devices must be correctly
interconnected and programmed to communicate properly.
This application note is not intended as a substitute for the CDP or
inverter manual, but as further information for those wanting to
interconnect both devices.
Even so, the instructions and manuals for each product should be consulted,
each company being responsible for providing respective technical support.
The different versions of inverter that can be managed by the CDP are:
 HUAWEI SUN2000-8KTL
 HUAWEI SUN2000-12KTL
 HUAWEI SUN2000-17KTL
 HUAWEI SUN2000-20KTL
 HUAWEI SUN2000-23KTL
 HUAWEI SUN2000-28KTL
 HUAWEI SUN2000-33KTL-A
 HUAWEI SUN2000-36KTL
 HUAWEI SUN2000-42KTL

2.- PRELIMINARY CONSIDERATIONS

The CDP's configuration stores the nominal power value of the inverter to be
controlled, and periodically sends it the power percentage that must be
generated; therefore, when the CDP communicates with the HUAWEI inverter, it
constantly sends it a regulation percentage.
In the event of operating with several three-phase cascaded inverters, the CDP's
"Inverter Power" variable must be set to match the power sum for all the
inverters, so that each inverter is sent the same regulation percentage.
In the event of single-phase inverters being used in three-phase installations, the
total power for all inverters must be programmed: select the three single
phases option in the "Phase" variable, and then, in the "Number of inverters"
variable, enter the number of 3 single-phase inverter units available in the
installation.
