  • Page 6: 1�- Introduction

    1�- INTRODUCTION KOSTAL offers several inverter models that can be managed via the CDP Dynamic power con- troller, specifically they are:  PIKO IQ 4�2-10  PIKO 10-20  PIKO 36 EPC 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.
  • Page 7: 2�- Kostal Piko Inverter

    2�- KOSTAL PIKO INVERTER The CDP and the inverter communicate via an RS-485 bus. This RS-485 bus can connect up to 32 inverters, although the number of inverters in the vast majority of domestic installations ranges from 1 to 3. 2.1.- COMMUNICATION CABLE To communicate with a KOSTAL PIKO inverter using a CDP, the inverter must be equipped with a communications card with an RS-485 interface (...

    2�1�1� CONNECTION OF ONE INVERTER shows the connection between the CDP and a single inverter. Figure 2 Figure 2:Connection between a CDP and a single inverter. 2�1�2� CONNECTION OF SEVERAL INVERTERS shows the connection between the CDP and several inverters.

    2�2�1� COMMUNICATION BETWEEN THE INVERTER AND THE PC BY ETHERNET CABLE The KOSTAL inverter is equipped with a web server that can be accessed using the IP address shown on the display of the unit. To view the IP address, follow the instructions below: 1�- Press the button in the main menu until the inverter icon appears shaded, as shown in Figure 6...

  • Page 12: 3�- Cdp Configuration

    3�- CDP CONFIGURATION There is a configuration web site for the CDP where all the parameters of the connected invert- er 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 The most important inverter parameters that have to be configured in the CDP are ( Table 6 Table 6:Parameters to be configured in the CDP. Parameter Description Inverter type Inverter model. In this case select: Kostal Inverter power Total power to be controlled by the CDP. Number of inverters Number of inverters to control.
  • Page 14: 4�- Communications Test And Regulation

    4�- COMMUNICATIONS TEST AND REGULATION 4.1.- COMMUNICATIONS TEST Check the communication between the inverter and the CDP, through the COM1 LED of the CDP:  When the KOSTAL inverter is selected the COM1 LED remains steady. This is because the communication is broadcast and thus the CDP cannot guarantee how many invert- ers are connected.
  • Page 15: 4�2�- Regulation Test

    4.2.- REGULATION TEST The following test can be performed to ensure the CDP is correctly performing the regulation: We assume a 3000 W inverter generating 1400 W. This value can be seen on the inverter display. Next, program the CDP indicating that the inverter power is 6000 W. The CDP will send the inverter a new setpoint so it can change its MPPT and the inverter will reduce photovoltaic gen- eration by 50%, generating 700 W.
