• Rule 21 is the interconnection standard in California that establishes advanced inverter functionalities and guidelines for communication between DERs and the electrical grid
• Will allow DG systems to continue operating during an abnormal grid event• Enhances reliability of electricity delivery• Reduces the power costs for consumers over time• Supports more stable and sustainable national energy strategies
https://enphaseenergy.wistia.com/medias/k7otf0tuvk
Rule 21
| © 2017 Enphase Energy, Inc.|CONFIDENTIAL28
• Three phases1. Basic Advanced Inverter Functions (defined by SIWG)
a) Adopted December 18, 2014b) Tariffs approved for PG&E, SCE, and SDG&E in July 2016c) Inverters must meet requirements starting September 2017
2. Communications (adopted in June 2016, timeline to take effect still undecided)
3. Additional Advanced Inverter Functions

Rule 21
| © 2017 Enphase Energy, Inc.|CONFIDENTIAL29
• Resilient anti-islanding• Provide low/high voltage ride-through• Provide low/high frequency ride-through• Provide low fixed power factor• Provide Volt/VAR active power priority• Reconnect by “soft-start” method• Optional functions (potentially mandatory in Phase 3):
• Frequency/Watt (decrease power on observed high frequency)• Volt/Watt (decrease power based on observed high voltage)• Volt/VAR reactive power priority (varies VARs based on observed voltage)
Phase 1 requirements: Autonomous Functions
