Hi, I'm using TMDSHV1PHINVKIT. Now I've encountered a problem when I did the grid-tie experiment. I use a 380V/2A DC source to supply the inverter. When I connected it to grid, I can see the inverter under normal inverter mode from GUI then turn into Dc Bus Voltage Over quickly.
Grid side uses 220V/50Hz ac source, resistor load is 50 ohm.
I've tested Open loop and Closed loop without PLL, which works well.
problem：
1、Why this board works not with the actual grid？
2、wrong reason of Dc Bus Voltage Over？ 380V/2A DC source is constant.
Does anyone know about this error? I need your help! Thank you!
