EMC and Harmonics — IEC 62920 / IEC 61000 Evidence for 60 Hz Dominican Grid Use China PV inverter EMC files are commonly based on GB/T 37408 and domestic laboratory reports. While those reports may include IEC 61000-family test methods, they are not automatically Dominican Republic EMC evidence unless the accepted standard, edition, limits, model coverage, and 60 Hz / 120-240 V configuration are clear to INDOCAL, SIE, the distributor, and the project owner.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)		 PV inverter EMC evidence for the Dominican Republic should be prepared around IEC-family documentation commonly used for power-conversion equipment, including IEC 62920 for PV power conversion equipment EMC and relevant IEC 61000-series harmonic, immunity, and emission tests. Because the Dominican Republic grid is 60 Hz and commonly 120/240 V at low voltage, EMC and harmonic files should identify the tested voltage/frequency configuration and confirm whether additional evaluation is needed when the original report was generated under China 50 Hz / 220-380 V settings.IEC 62920 — Photovoltaic power generating systems — EMC requirements and test methods for power conversion equipment
IEC 61000 series — Electromagnetic compatibility emission, immunity, and harmonic-current standards
INDOCAL/NORDOM standards and conformity context where adopted or required for the project		 Gap: A Chinese EMC certificate that does not identify IEC 62920 / applicable IEC 61000 clauses, model-family coverage, and 60 Hz operating configuration may not be enough for a Dominican Republic PV project file. Exporters should prepare IEC EMC reports, harmonic-current evidence, test configuration notes, and a mapping from the China report to the Dominican inverter firmware and nameplate configuration.[INFORMATIONAL] Do not rely on a China-only GB/T 37408 EMC file without checking IEC 62920 / IEC 61000 coverage and the Dominican 60 Hz / 120-240 V operating configuration. Confirm current INDOCAL, SIE, distributor, and project-owner EMC evidence expectations before final submission. International Electrotechnical Commission (IEC)2026-06-14 · unverified
SIE / Distributor Grid Interconnection — 120/240 V, 60 Hz Reconfiguration and Anti-Islanding China-side grid evidence commonly includes GB/T 19964-2024 for PV power-station grid connection, NB/T 32004 for PV grid-connected inverter technical specifications, and GB/T 37408 for grid-connected PV inverter technical requirements. These files are generally built around China's 50 Hz grid and 220/380 V low-voltage assumptions. They do not prove that the same inverter hardware, firmware profile, protection settings, relays, magnetics, thermal behavior, and anti-islanding detection have been validated for the Dominican Republic's 60 Hz / 120-240 V 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)		 Grid-tied PV inverter projects in the Dominican Republic should be reviewed through the applicable SIE electricity-sector framework and the serving distributor's interconnection process, commonly EDENORTE, EDESUR, or EDEESTE. The key technical issue for China-origin inverters is that the Dominican Republic is an Americas-style 60 Hz market with 120/240 V low-voltage service, not a China-style 50 Hz 220/380 V market. Inverter firmware, protection thresholds, reconnection delays, anti-islanding detection, voltage/frequency ride-through behavior, nameplate ratings, and commissioning locks should therefore be configured and validated for 120/240 V at 60 Hz before SIE/distributor review and site commissioning.SIE electricity-sector regulation and technical supervision

IEC 61727 — Photovoltaic systems — Characteristics of the utility interface
Dominican Republic low-voltage grid practice: 120/240 V, 60 Hz		 Gap: A China 50 Hz grid profile cannot be shipped as the default Dominican Republic configuration. Exporters should provide the Dominican Republic grid profile, firmware version matrix, 60 Hz anti-islanding evidence under IEC 62116, IEC 61727 grid-interface evidence, voltage/frequency trip windows, reconnection logic, installer lock procedure, and commissioning record template for the distributor. If the inverter was type-tested only at China 50 Hz / 220-380 V settings, reconfiguration and retesting should be planned before the SIE/distributor interconnection package is finalized.[INFORMATIONAL] Treat the Dominican Republic as a 120/240 V, 60 Hz grid market and lock that profile before shipment or commissioning. China 50 Hz / 220-380 V evidence does not prove SIE or distributor interconnection acceptance. Confirm current SIE rules and EDENORTE, EDESUR, or EDEESTE project requirements before final equipment submission. Superintendencia de Electricidad (SIE)2026-06-14 · unverified
CNE Net-Metering and Renewable Incentive Context — Project Gate Separate from China Certificates China distributed PV approvals, grid-operator acceptance, or domestic certificates do not create eligibility for Dominican Republic net-metering crediting or distributor interconnection. Chinese documents may support technical due diligence, but CNE/SIE/distributor project review is local.China distributed PV grid-operator procedures
GB/T 37408
NB/T 32004		 The Dominican Republic has a mature net-metering context for renewable self-generation, with CNE publishing a dedicated Programa de Medición Neta service. For rooftop and commercial PV projects, this programme context does not replace equipment safety, grid-interface, anti-islanding, EMC, or distributor interconnection evidence. It is a project and tariff/crediting gate that should be coordinated with CNE, SIE, and the serving distributor while the inverter documentation is prepared for the Dominican 60 Hz grid.CNE Programa de Medición Neta
Law 57-07 renewable-energy incentives context
SIE electricity-sector regulation
EDENORTE / EDESUR / EDEESTE distributor interconnection process		 Gap: Do not treat CNE net-metering eligibility as product certification, and do not treat China product certification as CNE net-metering eligibility. The project file should separately show CNE/SIE/distributor application status, utility meter/interconnection requirements, and inverter technical evidence configured for Dominican 60 Hz service.[INFORMATIONAL] CNE net-metering is a Dominican Republic project gate, not a substitute for inverter safety, EMC, anti-islanding, or distributor interconnection evidence. Keep the CNE/SIE/distributor application trail separate from China certificates and verify current CNE net-metering procedures before project submission.

INDOCAL / NORDOM Safety Conformity — IEC 62109-1 / IEC 62109-2 Evidence China PV inverter safety evidence is commonly based on GB/T 37408 and voluntary CQC/CGC or laboratory files. It may support due diligence, but it is not the same as IEC 62109-1/-2 type-test evidence and should not be represented as automatically accepted by INDOCAL, SIE, distributors, or Dominican 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)		 The Dominican Republic standards and conformity context is led by INDOCAL, which publishes Dominican standards (NORDOM), participates in international standardization, and provides product/process/service certification and conformity services. For PV inverters, the safety evidence normally expected in IEC-based procurement and conformity files is IEC 62109-1 and IEC 62109-2 for power converters used in photovoltaic systems. Exporters should confirm with INDOCAL, the importer, the SIE/distributor project reviewer, and the project owner whether IEC 62109 reports or certificates are accepted directly, adopted through NORDOM, or need a local conformity step.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
INDOCAL NORDOM standards and product/process/service conformity services		 Gap: A China domestic safety certificate alone is not enough to show Dominican Republic IEC/NORDOM conformity. Exporters should obtain IEC 62109-1/-2 type-test reports or certificates for the exact model or family, map the model variants and firmware versions supplied to the Dominican Republic, and confirm whether INDOCAL or the project requires additional local conformity documentation.[INFORMATIONAL] Plan around IEC 62109-1/-2 safety evidence and confirm the INDOCAL/NORDOM conformity route before shipment. China GB/T 37408 safety evidence can support the file but should not be treated as automatic Dominican Republic acceptance. Instituto Dominicano para la Calidad (INDOCAL)2026-06-14 · unverified
