Part Number: TMDSSOLARUINVKIT

Hi,

I have purchased this Solar Inverter Kit and am trying to make it work in Lab Environment. I have done the following steps so far:

1. Powered with 12 and 15V power supplies

2. Shorted TP8 and TP9

3. Connected a lab voltage supply (30V) between PV+ and PV-.

At this point, I was expecting to get a 110V output. But I am only able to measure ~100mVrms. What other steps do I need to follow. 

Also, I am not sure where to get the software to control the PCB, or which software to use as it did not come with any DVD or USB drives.

    Thank you for the response. I was working with the ControlSuite software as you had suggested. Page 6 of the quick start guide for this part has the following instructions. Step 2 requires having GUI composer and I do not know where to find this program.

    As controlSUITE is no longer maintained some of the features are not working due to changes in OS and windows etc.

    You will need to follow the UG not the QSG,

    Hi Manish,

    Thank you for the response. I am following your suggestion and am able to communicate with the equipment. I had a question about hooking up the equipment to the grid. Does connecting to the grid simply mean connecting the output of the inverter (TP15 and TP16) to a wall plug, or should it go to the main panel of the house?

    I am referring to the figure below when asking this question.

    Anurag, 

    This design is meant to help you understand the system and is not a complete end equipment design, and only to be tested under lab environment.

    I will recommend testing it with AC source and emulated connection as described in the UG.

    Thank you. I have a follow up question as I am still having an issue with the board to work. I am following instructions on page 32 of the User guide. I have set the Build = 1, MPPT = 0, Grid_Connect = 0.

    I have an 800 ohm resistor connected between TP8/9 and TP10and have connected a 50V power supply between TP12 and 13. Here is what I am seeing:

    1. The system is not drawing any current from the power supply.

    2. I follow instructions on page 34 of the UG and set the value of ClearFlyBacktrip = 1. However, when I do this the EPwm3Regs.TZFLG.all variable does not go to 0. Its value remains at 8

    3. I do not measure any significant voltage between TP8/9 and TP10. 

    I would appreciate any help in figuring this issue out.

    Thanks
