The qualification boundary is at BESS AC terminals; POI ramp needs are verified via approved POI proxy profiles and/or EMT models. Core controls include autonomous island operation, reactive power support within PCS limits, seamless grid/island transition, and black start. Instrumentation requirements apply across tests; all tests run at AC terminals unless marked model-only.","sledRelevance":"Gives SLED facilities and EPCs the actual control/test vocabulary behind DSX Ready BESS claims—especially islanding and black-start—so reviewers can demand packet evidence rather than logo slides.","evidence":"PRD Compliant/Non-compliant/Exception responses; Core Requirements checklist; CTRL-CORE-01 island mode; GRID-CORE-02 reactive support; MODE-CORE-01 grid/island transition; MODE-CORE-02 black start; AC-terminal test boundary; POI proxy/EMT for ramp; instrumentation table applies to all tests.","architectureImplications":"Design reviews must align PCS controls and instrumentation to the Core Requirements list and treat POI behavior as out-of-boundary unless modeled via approved proxies.","governanceImplications":"Require complete self-qualification packets (plots, time-series, pass/fail) before accepting Ready marketing in campus procurements.","securityPrivacyImplications":"Materials/safety/compliance disclosure step includes regulatory certifications; cybersecurity evidence is expected in partner packets but not reproduced here.","caveats":"Vendor standard, not third-party audited results for a specific SKU; undated page; distinct from the already-archived BESS self-qualification guidelines overview URL.","streamIds":["nvidia"],"roles":{"sales":"Bring this doc when a partner waves DSX Ready BESS without evidence. Ask which Core Requirements were tested at AC terminals—island, black start, reactive support, grid/island transition—and whether any POI claims are only proxy or EMT.

Architecture work maps Core Requirements to controls settings and instrumentation plans. Prerequisites include the OEM packet, a site model, and utility islanding rules. Proof of value: each Core ID has cited test evidence collected at AC terminals, with POI items explicitly labeled proxy/model.","delivery":"Work is packet completeness review and a site-gap list owned by the facilities standards engineer.
