Application notes
1.- INTRODUCTION
DELTA offers several inverter models that can be managed via the
CDP
Dynamic power controller.
For the
CDP
controller to be able to correctly manage the inverter,
communication between the two devices must be correct and both products
must be correctly programmed.
These application notes are not meant as a substitute for the
CDP
or
inverter manuals, but rather as additional support for individuals who
need to interconnect the two devices.
Even so, the guides and manuals of each product should be consulted and each
company is responsible for providing technical support.
An inverter from the
PRI
family of inverters will be used as a model in these
application notes.
2.- DELTA PRI M8A 8kW INVERTER
The
CDP
and the inverter communicate via an RS-485 bus. This RS-485 bus
can connect up to 100 inverters, although the number of inverters in the vast
majority of domestic installations ranges from 1 to 3.
