    Dear TI experts!

    For a few questions about the inverter solution selection, TI's experts please kindly  to give us guidance:

    1. The following are the requirements of our customers for 1KW PV inverters as follows:

      1)1KW output power,

    2) Battery: 12V, 100A (discharged), 50A (charged)

    3)MPPT 600w (18V-56V)

    1. Is TIDA-010933 the closest to the need, or is there a more suitable one?

    3.Is the circuit logic of TIDA-010933 MPPT like this?

       SW comes out directly to the PCS and the battery, directly on the same bus, or need to add a management circuit?

       

    4.Is there a design file in PADS or cadence or AD format for TIDA-010933 Schematic?

    1. MPPT step-down type

      36V(15V-60V) step-down to 12V MPPT scheme, what is the recommended scheme for TI?

    1. We have the demand for 1KW and 5KW bidirectional inverters, considering the cost factor, for 1KW, or still recommend ST280039, or are there other better matching solutions to recommend?

    7.If we want to reduce costs, which parts must be retained, and which peripheral devices can be considered to be replaced, so that we can use the SDK software provided by TI

    Best Regards!

  • Dear TI experts!

     Our product needs,
    1. The battery needs to  charge and discharge  management, and it can be trickle-charged, constant-current charged, and constant-voltage charged according to the state of the battery.
    2. Over-current, over-voltage, under-current, under-voltage, and short-circuit protection are required
    The currently recommended reference scheme, especially the SDK,whether the software has a corresponding exception handling mechanism

    Dear TI's experts:
    Continuing with the above question, for the 1KW and 5KW product requirements that we currently need to design,
    Our product needs,
    1. The product solution needs to realize the charging and discharging management of the battery, and can carry out trickle charging, constant current charging and constant voltage charging according to the state of the battery. Is it possible to use a single TI 280039 to communicate with the BMS for RS485/CAN, and does the SDK have this function?


    2. Over-current, over-voltage, and short-circuit protection are required
    The recommended reference schemes, especially whether the SDK and reference software have the corresponding exception handling mechanism


    3. If 2~3 inverters are to be paralleled, what kind of solution does TI recommend to achieve it? Does TI have a corresponding parallel synchronization and power allocation control mechanism, and has it been implemented on the SDK?


    4. Charging priority management, what kind of circuit scheme is recommended, and help recommend TI scheme


    5. To improve the dynamic response of the load, in addition to the redundancy of reserved power devices, does TI's SDK adopt the corresponding processing method in terms of software? What is the performance achieved so far?


    6. Whether TIDA-010933's current reference design SDK of TI supports the grid-connected function

    Best Regards!

  • TIDA-010933 is the closest to the need. Only ref design available at this time.

    TIDA-010933 MPPT has boost circuits. Pls see the associated doc.

    SW comes out directly to the PCS and the battery, directly on the same bus, or need to add a management circuit? This question is not clear. The s/w is available in C2000 DP SDK folder.

    Design files are avalable inside the folder in C2000 DP SDK where TIDA--010933 is saved.

    36V(15V-60V) step-down to 12V MPPT scheme, what is the recommended scheme for TI? Use the DC/DC buck converter for this.

    We dont do detail cost analysis. Pls do your own cost assessment

  • Thanks Shamin for the reply!


    A few more questions:
    1. Paralleling: Does TI have a solution for inverter parallelism management to realize the synchronization and power balance distribution of master-slave machines after paralleling?


    2. MPPT: Please kindlly recommend TI's 600W step-down MPPT, and  TI 280039 reference software support that MPPT 


    3.Is there a design file in PADS or cadence or AD format for TIDA-010933 Schematic?
