California utilities have begun asking for proof of compliance with Rule 21. Enphase has you covered!

Enphase Rule 21 compliance is achieved with the application of the Enphase CA Rule21 201709 grid profile to certified hardware. The grid profile defines utility approved operating parameters for those California Enphase systems whose application for interconnection was submitted after September 8, 2017.

Use the resources below to learn how to apply the CA Rule21 201709 grid profile to your certified hardware, and how to generate a compliance report for your utility.

Certified hardware

The IQ platform and S-Series Microinverters are certified for Rule 21. Visit the CEC website here for a simplified listing of compliant products, or download the UL compliance documents:

  • The IQ certification can be found here.
  • The S-Series certification can be found here.

Grid profile application 

The grid profile can be applied any time before, during or after installation.

Prior to Install: This is the recommended approach. Without ever leaving the office, simply select the CA Rule21 201709 grid profile on the site activation form and the profile will be applied to the microinverters when the site Envoy connects to Enlighten. Watch this video to learn how to apply the grid profile using the activation form.

During Install: If the profile has not already been set prior to the installation, set it during the installation using the Installer Toolkit mobile app. Watch this video to learn how to apply the profile using the Installer Toolkit, and how to generate a Summary Report to demonstrate Rule 21 compliance.

After Install: Have systems that have already been installed, and need to add the Rule 21 profile? You can apply the CA Rule21 201709 grid profile and run the report at any time simply by updating the system activation form. Watch this video to learn how to apply the grid profile using the activation form.

Compliance reporting

A utility compliance report can be generated at any time. The instructions for how to do that are included in the profile application videos above.
