Chilicon/Intertek Certifies the CP-250E Micro-Inverter as UL 1741 SA Smart Inverter:
California Rule 21 phase 1 requirements took effect in September 2017, meaning that solar inverter makers are required to achieve UL1741SA certification to continue selling inverters in California. The phase 1 requirements, a.k.a. the autonomous functions, mean that the inverter can automatically, without any intervention by a human, take actions to support the grid in case local grid conditions go wrong. Those functions are as described by Chilicon in the press release below. What's interesting is they could implement the update without changing the control board -- it's just a software change.
Over the next year or two further requirements, phases 2 and 3, will kick in requiring communication across the Internet with cloud systems for command/control of inverter capabilities. The goal is even more support of electricity grid reliability as well as orchestrating energy production and energy storage systems to time-shift electricity produced from renewable resources to other times of the day.

Newest Products from Enphase Energy Meet the Needs of the California and Hawaii Markets
In California and Hawaii, policy changes are underway requiring "smart inverters" for solar power systems. Requirements going into effect in September call for what's called "Phase 1" functions, comprising a set of "autonomous" actions providing "grid support" functions like voltage or frequency support. That is, these functions happen automatically without any explicit control, and act in reaction to grid conditions. For example the voltage or frequency might go out of bounds, and rather than disconnect from the grid the inverter instead shifts into a mode of helping to correct the problem.
The industry developed a supplemental standard, UL1741SA (Supplement A), defining those autonomous functions. Shortly Enphase, and the other solar inverter manufacturers, will be unable to sell inverters in California that lack this feature.
