Initial reviewed records for five equipment scopes. Other catalog equipment remains unreviewed; an absent record does not mean a product is uncertified.
Battery · UL 1973
Component safety scope. It does not establish the complete inverter/battery system listing.
System · UL 9540
Match the listed ESS model, component combination, count, version and conditions.
Fire testing · UL 9540A
Check the actual edition, test level, samples and full report. A fire-test reference is not a UL 9540 listing.
Enclosure · NEMA / IP
Environmental protection is a separate scope. NEMA does not certify products; IP and NEMA Types are not automatically interchangeable.
Registry matched means the issuing directory named the exact model at the recorded review. Certificate / test document reviewed means the document was inspected; current registry standing may still be unknown. Manufacturer assertion identifies a datasheet statement without an independently matched laboratory record.
Expired or withdrawn records, when documented, remain labelled as historical evidence. An old document is not automatically expired. An unstated expiry remains unknown. Nothing here grants local installation approval, utility acceptance or incentive eligibility.
Intertek’s public battery listing includes this model. The linked certificate covers the battery module; it does not certify an arbitrary inverter/battery installation.

WP-16/280-1AWLL
The manufacturer identifies WP-16/280-1AWLL and WM-48-280-1-AW as the marketed 280Ah All Weather battery. Check the delivered nameplate and production suffix; retailer listings do not establish every manufacturing revision.
Match the exact battery nameplate, accepted standard edition and conditions of the complete listing.
EG4 280Ah All Weather + FlexBOSS18/21 · specified ESS
Registry matched · 2026-11-07
The directory and certificate identify specified whole-system model codes. A battery purchase alone does not supply the listed system. The model code sets inverter family, inverter count, battery count and product-version suffix.

Certificate model patterns may carry the 00–99 product-version suffix. Verify the exact version and installation/listing report; do not substitute indoor, 314Ah, rack or other inverter families.
FlexBOSS21 (IV-16000-HYB-AW-) or FlexBOSS18 (IV-13000-HYB-AW-), with the specified 280Ah All Weather battery model.
Within this certificate: one inverter with 1–6 batteries; two inverters with 2–6; three inverters with 3–6. These ranges do not apply to unrelated systems.
The EG4 explanation references earlier dates for the same report; the retained certificate itself is issued August 6, 2025. Listing-report conditions and current project acceptance still need confirmation.
