Tool/software:
Based on looking at the code, GPIO 30 and 31 are used for the rapid shutdown mechanism for this inverter. However, I am not able to tell all of what triggers the rapid shutdown command. I see that there is RSD triggered after overvoltage, overcurrent, and temperature. I was also wondering if this inverter includes an anti-islanding rapid shutdown, that shuts down when it isn't able to sense the signal from the grid?
