Certificates & marks

California equipment records used by some programs and authorities.

Applies to

The exact equipment model and category on the California list.

Check

Exact list, model and underlying certificates.

Limits

CEC listing is not a safety certificate or universal installation approval. Check the underlying UL 9540 system and UL 1973 pack records separately.

Safety of the listed energy storage system.

Applies to

Specified energy storage system: battery, controls and conversion equipment within the listed boundary. A DC ESS listing can cover a DC system; check the required inverter and configuration.

Check

Covered equipment, quantities, revisions and compatibility conditions.

Limits

UL 9540A is a different test method. Match the complete listed configuration; local installation rules still apply. Insurance eligibility and loss coverage depend on the insurer and policy, not this mark alone.
