CCS/TMDSSOLARPEXPKIT: Running the program using real PV panel instead of PV emulator

Part Number: TMDSSOLARPEXPKIT

Tool/software: Code Composer Studio

Hello everyone,

I am now trying to run the given project (1: PV Inverter; 2: PV Battery Charging) using a real 50W PV panel instead of the built-in PV emulator. Below is the questions regarding this scenario.

  1. How to actually connect the panel to the board? The port of the board is Banana female port, while the panel uses MC4 connector 1 male 1 female. I noticed that you can actually connect the MALE of the MC4 connector (positive of PV output) to the MALE banana cable. Thus using the banana cable it could connect the board. However, I have no idea how to connect the FEMALE of the MC4 connector (negative of PV output) to the board.

  2. I need to modify the 2 given projects that it could run with the external power source instead of using built-in emulator, but I do not know how. Could anyone tell me how to? Thanks.

Thank you!

Best regards,

Yue

    Yue,

    1. I am not familiar with the connector in question, i feel you should ask someone at digikey, arrow or other vendors for the suggestion. Providing connection suggestion is not something possible for us to do given the wide variety of them being available and nonfamiliarity with all of them.

    2. The control code does not use any infor from the in built emulator, hence connecting an external one is simply disconnecting the banana output of the in built panel emulator and connecting the external source (please make sure voltage and current ratings are not exceeded for any power stage on the board).
