Page 6: Introduction
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. -
Page 7: Inverter
Example: if there are 6, 2kW single-phase inverters (2 in phase L1, 2 in phase L2 and 2 in phase L3), the following must be configured: • Inverter power: 12000W • Number of inverters: 2 • Phase: three single phases Whereas in the event of 3, 2kW single-phase inverters (1 inverter in each phase), configuration must be as follows: •... -

Page 12: Cdp Configuration
4.- CDP CONFIGURATION The CDP has a configuration web site where all the parameters of the connected inverter have to be entered. To do so, enter "/setup" at the end of the navigation bar where the CDP is monitoring so that the following, for example, appears in the navigation bar: “10.0.110.212/setup”... -
Page 13: Regulation Test
5.- REGULATION TEST To ensure correct CDP management, we recommend regulation tests by varying consumption and changing the CDP’s configuration. By way of example: Suppose we have a 3000W inverter that is generating 1400W (this can be seen on the inverter's display or by using the SUN 2000 APP). If we program the CDP to indicate that the inverter's power is now 6000W (instead of 3000W, which would be correct), the CDP would send a new signal to the inverter for it to modify its MPPT and the inverter would reduce its output by... -
