TIDA-010933: Follow-up on 120V 60Hz Grid operation

Part Number: TIDA-010933


Tool/software:

I felt my last question wasn't clear enough, so I'm following up with a more precise one. I'm currently using these parameters:

initialization
uINV_DCAC_Amplitude=0.846;
uINV_ACDC_AC_FREQ_HZ = 60;
sogi:
SPLL_1PH_SOGI_config(&uINV_spll_1ph,
60, // changed to 60
20000,
uINV_SPLL_COEFF_B0,
uINV_SPLL_COEFF_B1);
I'm using Vref of 200V 

the goal is to obtain 120Vrms grid tied operation. (might push a lil higher to 125V to ensure proper power flow)
However, I'm unsure if I need to edit the PI controller's in any way so they're less aggressive and what other settings need to be changed to achieve this?
Best,
Juan Luera

    Forgot to mention I also lowered the trip limit to 230:

    #define uINV_ACDC_vDC_TRIP_LIMIT_V ((float32_t) 230 ) // from 440
    I kept most everything else the same and I wan't sure if I should change this 
    #define uINV_ACDC_vAC_MAX ... currently at 396.65. LLM's recommend I reduce it, but from what I've seen this is just a scaling factor and there is no limits on the ac output.
