Page 6: Introduction
4. Fronius ECO WLAN (three-phase) 5. Fronius Primo WLAN (single-phase) The CDP stores the nominal power value of the inverter to be controlled in its configuration and periodically sends the inverter the percentage of said power to be generated. Consequently, when the CDP communicates with the Fronius inverter it is constantly sending it a regulation percentage. -

3.- FRONIUS IG PLUS INVERTER WITH MODBUS CARD The CDP and the inverter communicate via an RS-422 bus. This RS-422 bus can connect up to 100 inverters, although the number of inverters in the vast majority of domestic installations ranges from 1 to 3. -

Page 20: 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 21 The most important inverter parameters that have to be configured in the CDP are (Table 7): Table 7: Parameters to be configured in the CDP. Parameter Description Inverter model, in this case selecting: Fronius Inverter type Inverter power Total power to be controlled by the CDP.

Page 22: Communications Test And Regulation
The flashing rate is one flash per second (if there is one inverter) and 1/n if there are several inverters (where "n" is the number of inverters connected). If the COM1 LED is off, it means the CDP is not communicating with the inverter. In this case check the communication cables and the inverter communication configuration. -
Page 23: Regulation Test
Let us suppose a 3000W inverter generating 1400W. This value can be displayed on the inverter. If we now program the CDP indicating that the inverter power is 6000W, the CDP will send the inverter a new setpoint to change its MPPT and the inverter will reduce the photovoltaic generation by 50% and generate 700W. -
