How do I check if a ti inverter is grid connected?
TI recommends to use a controlled source at the output, such as an AC power supply to verify grid connected operation. Once the operation is verified, check the functioning of the inverter with direct grid connection. Bias supply to the board is provided by an isolated 15-V supply connected to J2 and S1 in the ON position. Figure 32.
How to set up a DC inverter?
As soon as the input DC voltage is raised above 200 V, for this setup, hear the relay click when the inverter starts. Increase the DC bus up to the rated voltage of 380 V. Now increase the current reference to modulate the power that is fed from the inverter by changing invIoRef.
