You will be required to have a smart inverter now, that went into effect about 2 weeks ago. I have no clue how that would affect my system since I have microinverters.

The old inverters were mandated to disconnect if the voltage and frequency are outside a certain range. So if a disturbance occurs, all of the solar on that line drop off, causing a worse disturbance. The new regulations, UL 1741 SA, require "ride through" and power factor support.
It is so bad in Hawaii, I believe they are requiring people to retrofit their inverters.
