Inverters

The inverter listing request form and instructions were updated and posted on December 5, 2019. These updates reflect advanced functionalities and communication features, and will be reflected in the Grid Support Inverter List starting January 2020.

Additionally, starting January 1, 2020, Energy Commission staff will no longer accept requests for listing utility interactive inverters that do not include grid support functions ("smart inverters"). A list of these utility interactive inverters will be archived and available on our website.

The Energy Commission updates the solar equipment lists three times a month, typically on the 1st, 11th, and 21st of the month, or the first business day thereafter.

For any questions regarding the equipment lists, please contact the Solar Equipment Call Center at SolarEquipment@energy.ca.gov or 916-654-4120.

List of Inverters

There are two versions of the list of inverters that are available for download - Simplified and Full Data. The Simplified version is intended to show only basic information about the inverters such as manufacturer, model number, description, and weighted efficiency. The Full Data version contains additional information such as certification dates, reported nameplate ratings and efficiency measurements that may be of interest to stakeholders.

Grid Support Inverters

Utility Interactive (Non-Smart) Inverters

(The utility interactive inverter list will be updated until January 2020, at which time the list will be archived.)

Submitted information is reviewed by the California Energy Commission prior to equipment being added to the Energy Commission's Solar Equipment Lists but it is not continuously monitored. The California Energy Commission does not confirm manufacturers' self-reported information. Please note that equipment on the Energy Commission's Solar Equipment Lists have undergone tests to achieve minimal safety and performance standards. The California Energy Commission and the State of California make no claim or warranty on the equipment and its safety, performance or durability. Anyone considering installing solar energy systems are encouraged to conduct their own research.

Eligibility

For information on equipment eligibility and required laboratory-tested data, please refer to the SB 1 Guidelines, Appendix B.

Forms

Instructions

Inverter Manufacturer Attestation Form

To reflect the advanced inverter functions of Monitoring Data and Scheduling on the Solar Equipment Lists the manufacturer must provide a completed attestation. A copy of the attestation form can be found on the IOUs websites. All forms are identical.

Other Resources

The California Energy Commission is providing consumers a website list of resources and links for informational purposes; where they can research topics such as: PV product recalls, contractor license check for solar retailers/ installers or solar installation building and fire code requirements.
