Compliance Gap Matrix
| Compliance item | Common China baseline | Jamaica (BSJ / OUR / JPS) | Gap / action | Source + verification date |
|---|---|---|---|---|
| EMC — IEC 62920 and IEC 61000 Evidence for Jamaica Solar PV Inverters | Chinese PV inverter EMC evidence commonly comes from GB/T 37408-2021 and related domestic test reports from CNAS-accredited laboratories. Those reports may use IEC 61000-family methods, but the report scope, test configuration, declared voltage, and acceptance route are Chinese domestic evidence. They should not be treated as automatically equivalent to IEC 62920 or project-specified IEC 61000 evidence for Jamaica.GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters) NB/T 32004 — 光伏并网逆变器技术规范 (Technical Specification for Photovoltaic Grid-Connected Inverters) |
For solar PV inverters supplied into Jamaica, EMC evidence should be prepared around internationally recognised PV inverter EMC standards and any BSJ-adopted or project-specified requirements. Practical evidence normally includes IEC 62920 for photovoltaic power conversion equipment EMC and applicable IEC 61000-series reports, including harmonic-current and disturbance evidence relevant to the inverter rating and installation. Because Jamaica's electricity sector is regulated by OUR and grid connection is reviewed through JPS/project processes, EMC reports should be tied to the exact inverter model, firmware, power rating, and grid configuration supplied.IEC 62920 — Photovoltaic power generating systems — EMC requirements and test methods for power conversion equipment IEC 61000 series — Electromagnetic compatibility test methods and limits, including harmonic-current limits where applicable Bureau of Standards Jamaica (BSJ) standards adoption and conformity context Office of Utilities Regulation (OUR) electricity-sector oversight |
Gap: GB/T 37408-2021 EMC evidence is not an automatic substitute for Jamaica BSJ, JPS, or project-owner EMC documentation. Exporters should prepare IEC 62920 and applicable IEC 61000 reports for the exact model and rating supplied, check whether the report covers 110/220 V operation at 50 Hz, and obtain a project-specific acceptance position from the Jamaica engineer, importer, or utility interface reviewer before shipment.[INFORMATIONAL] Prepare IEC 62920 and applicable IEC 61000 EMC reports for Jamaica rather than relying only on China GB/T 37408-2021 EMC evidence. Confirm that test configurations cover the supplied inverter rating and Jamaica's 110/220 V, 50 Hz operating conditions, and verify any BSJ or project-owner documentation requirement before shipment. | Bureau of Standards Jamaica (BSJ)2026-06-14 · reference |
| Jamaica Grid Interconnection — IEC 62116 / IEC 61727 Evidence and 110/220 V, 50 Hz Settings | Chinese grid-connection evidence commonly includes GB/T 19964-2024 for photovoltaic power station connection, NB/T 32004 for photovoltaic grid-connected inverter technical specifications, GB/T 37408-2021 for inverter technical requirements, and domestic anti-islanding results. These documents are built around Chinese grid conditions and domestic acceptance routes. They do not automatically satisfy JPS or project-owner review in Jamaica, especially where inverter protection settings were validated only for China's 220/380 V, 50 Hz grid.GB/T 19964-2024 — 光伏发电站接入电力系统技术规定 (Technical Requirements for Connecting Photovoltaic Power Station to Power System) NB/T 32004 — 光伏并网逆变器技术规范 (Technical Specification for Photovoltaic Grid-Connected Inverters) GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters) GB/T 156 — 标准电压 (Standard voltages) |
Solar PV inverters intended for grid connection in Jamaica should be documented for JPS interconnection review and OUR-regulated electricity-sector requirements. Practical inverter evidence normally includes IEC 62116 anti-islanding test evidence and IEC 61727 utility-interface evidence, plus project-specific protection settings for Jamaica's 110/220 V, 50 Hz grid. Jamaica has the same 50 Hz frequency as China, but the service voltage is materially different: 110 V single-phase and 220 V split-phase, with US-influenced distribution practice, instead of China's 220 V single-phase and 380 V three-phase baseline.IEC 62116 — Utility-interconnected photovoltaic inverters — Test procedure of islanding prevention measures IEC 61727 — Photovoltaic systems — Characteristics of the utility interface Jamaica Public Service (JPS) interconnection and project review requirements for grid-connected generation Office of Utilities Regulation (OUR) electricity-sector oversight |
Gap: China GB/T and NB/T grid-connection documents should not be treated as automatic substitutes for Jamaica interconnection evidence. Exporters should prepare IEC 62116 and IEC 61727 test reports for the supplied inverter model, document anti-islanding and reconnection settings, and validate firmware for Jamaica's 110/220 V, 50 Hz service conditions. The frequency match with China reduces one configuration issue, but the voltage mismatch is material and can affect protection thresholds, nuisance trips, and interconnection approval.[INFORMATIONAL] Treat Jamaica interconnection as a separate JPS and project-engineer review from China domestic grid approval. Prepare IEC 62116 and IEC 61727 evidence and verify inverter firmware against Jamaica's 110/220 V, 50 Hz grid before submission. Do not rely on GB/T 19964-2024, NB/T 32004, or GB/T 37408-2021 as automatically accepted substitutes. | Jamaica Public Service Company Limited (JPS)2026-06-14 · reference |
| IEC 62109-1 / IEC 62109-2 Safety Evidence — Jamaica BSJ / JPS Solar PV Projects | Chinese solar PV inverter safety evidence commonly references GB/T 37408-2021 and NB/T 32004, supported by domestic CQC/CGC or laboratory documentation. These Chinese documents may address safety topics, but they are not IEC 62109-1/-2 type-test certificates and are not automatically accepted by Jamaica importers, BSJ-related conformity review, JPS project engineers, or project owners.GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters) NB/T 32004 — 光伏并网逆变器技术规范 (Technical Specification for Photovoltaic Grid-Connected Inverters) |
Solar PV inverters supplied into Jamaica should carry safety evidence aligned with IEC 62109-1 and IEC 62109-2 for power converters used in photovoltaic systems. BSJ is Jamaica's national standards body, OUR regulates the utilities sector, and JPS/project engineers may require safety certificates and test reports before grid connection or installation acceptance. IEC 62109-2 covers inverter-specific safety requirements and depends on IEC 62109-1 general requirements; evidence should be model-specific and should identify the operating voltage configuration supplied for Jamaica.IEC 62109-1 — Safety of power converters for use in photovoltaic power systems — Part 1: General requirements IEC 62109-2 — Safety of power converters for use in photovoltaic power systems — Part 2: Particular requirements for inverters Bureau of Standards Jamaica (BSJ) standards adoption and conformity context Jamaica Public Service (JPS) project interconnection and installation review context |
Gap: Chinese GB/T or NB/T safety documentation should be supplemented with IEC 62109-1/-2 test reports or certificates for the exact inverter model or certified model family. Exporters should verify that the certificate covers the voltage and grid configuration supplied into Jamaica and that any importer, project-owner, BSJ, or JPS documentation requirement accepts the issuing laboratory and report scope.[INFORMATIONAL] Do not rely on China GB/T 37408-2021 or NB/T 32004 safety documentation alone for Jamaica projects. Prepare IEC 62109-1/-2 model-specific evidence and confirm acceptance with the importer, BSJ-related conformity reviewer, JPS/project engineer, and project owner before shipment or installation. | Office of Utilities Regulation (OUR), Jamaica2026-06-14 · reference |
