EMC — IEC 62920 and IEC 61000-Series Evidence for PV Inverters Chinese PV inverter EMC evidence is commonly tied to GB/T 37408 and domestic CNAS test reports. While Chinese test programmes may use IEC 61000-family methods, the certificate scope, limits, grid conditions, and firmware settings may not match IEC 62920 or Honduras project requirements. China reports generated at 50 Hz / 220-380 V should not be treated as proof of EMC and harmonic behaviour at Honduras 60 Hz / 120-240 V conditions unless the report scope explicitly covers those conditions.GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters) — includes domestic EMC-related requirements
NB/T 32004 — 光伏并网逆变器技术规范 (Technical Specification for Photovoltaic Grid-Connected Inverters)		 For Honduras PV inverter projects, EMC evidence should be aligned with the standard named by the project owner, OHN-adopted standards where applicable, and CREE/ENEE interconnection expectations. IEC 62920 is the dedicated EMC standard for PV power conversion equipment and draws on IEC 61000-series test methods; harmonic current and emission evidence may also be requested under IEC 61000-series standards. Because Honduras uses a 60 Hz / 120-240 V grid environment, EMC and harmonic reports should identify the test voltage, frequency, power rating, firmware profile, and grid-code configuration used for the tested inverter.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 and emission evidence where applicable
OHN / project-owner standards adoption to be confirmed for the specific Honduras project		 Gap: GB/T 37408 EMC evidence is not a clean substitute for an IEC 62920 / IEC 61000 evidence package requested for a Honduras project. Exporters should map each Chinese EMC report to the Honduras specification, confirm whether the laboratory accreditation and test configuration are acceptable, and retest if the existing report does not cover 60 Hz, 120/240 V or 240 V service, the same model rating, and the same firmware grid profile.[INFORMATIONAL] Do not assume a China GB/T 37408 EMC certificate is enough for Honduras. Prepare an IEC 62920 / IEC 61000 mapping, confirm OHN or project-owner acceptance, and make the 60 Hz / 120-240 V test configuration visible in the evidence package.

Honduras Grid-Connection Standards — CREE / ENEE / ODS Interconnection and 60 Hz / 120-240 V Settings Chinese grid-connection evidence commonly includes GB/T 19964-2024 for PV power stations connected to the power system, NB/T 32004 inverter technical specifications, GB/T 37408 technical requirements for PV grid-connected inverters, and domestic anti-islanding test evidence. These documents are based on Chinese 50 Hz grid conditions and typical 220/380 V settings. They are useful for understanding model capability but do not automatically satisfy CREE, ENEE, ODS, or project-owner acceptance in Honduras.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)
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)
GB/T 156 — 标准电压 (Standard voltages)		 Honduras PV inverter grid connection is reviewed through the Honduran electricity-sector framework: CREE publishes the laws, regulations, technical norms, and procedures for the sector; ENEE is the national utility and is linked to the system operator/ODS context; and project interconnection must satisfy the applicable distribution, transmission, or autoproductor route. For inverter evidence, project specifications commonly refer to IEC 62116 anti-islanding, IEC 61727 utility-interface characteristics, and local interconnection settings. The important electrical difference is that Honduras uses an Americas-style 60 Hz / 120-240 V supply environment, not the 50 Hz / 220-380 V China baseline. Firmware protection thresholds, anti-islanding trip windows, reconnection delays, voltage ranges, frequency windows, and phase configuration must be parameterised and tested for the Honduran point of connection.CREE — Leyes, Reglamentos, Normas Técnicas y Procedimientos for the Honduran electricity sector
CREE Norma Técnica de Usuarios Autoproductores — residential and commercial renewable self-generation framework
CREE Norma Técnica de Acceso, Conexión y Uso de la Red de Transmisión — access, connection, and use of transmission network
IEC 62116 — Utility-interconnected photovoltaic inverters — Test procedure of islanding prevention measures
IEC 61727 — Photovoltaic systems — Characteristics of the utility interface
Honduras grid context — 60 Hz / 120-240 V service environment		 Gap: Chinese 50 Hz / 220-380 V grid evidence does not prove Honduras 60 Hz / 120-240 V interconnection behaviour. Exporters should prepare a Honduras configuration record, IEC 62116 anti-islanding evidence at 60 Hz where required, IEC 61727 utility-interface evidence where specified, and project-specific protection settings for ENEE/ODS or distribution review. Do not ship units locked to China default grid codes without documented reconfiguration and retesting where the firmware or protection profile materially changes.[INFORMATIONAL] Treat CREE rules plus ENEE/ODS interconnection review as Honduras project gates. China GB/T and NB/T reports can support technical due diligence, but the inverter must be configured and, where required, retested for Honduras 60 Hz / 120-240 V operation before interconnection acceptance.

Distributed Generation / Autoproductores — CREE Rules and ENEE Project Acceptance China distributed PV connection approvals are handled under Chinese national and grid-company rules, with product evidence commonly based on GB/T 37408, NB/T 32004, GB/T 19964-2024, and factory grid-code settings for China. Those approvals do not establish that the same inverter is eligible for Honduras autoproductor injection, netting, metering, or commissioning arrangements.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 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)		 CREE's published legal and technical-norms page identifies the Norma Técnica de Usuarios Autoproductores as the framework for residential and commercial users that install renewable generation equipment to supply their own consumption and receive remuneration for injected surplus energy. For a Chinese inverter, this means the compliance package is not only a product test file: the installer or project sponsor must align the inverter model, protection settings, metering arrangement, injection limits, and commissioning evidence with the CREE autoproductor rule and the distributor/ENEE acceptance process. Honduras has significant solar penetration and SIEPAC regional interconnection context, so project engineers may apply additional stability, voltage, and frequency ride-through expectations for larger systems.CREE Norma Técnica de Usuarios Autoproductores — residential and commercial renewable self-generation and surplus injection framework
CREE Reglamento de Servicio Eléctrico de Distribución — distribution service conditions
ENEE / distributor interconnection and commissioning acceptance for grid-tied installations
SIEPAC / Central American regional interconnection context for larger grid-impact projects		 Gap: China domestic distributed-PV acceptance does not transfer to Honduras autoproductor or distributed-generation approval. Confirm the applicable CREE route, distributor/ENEE documents, metering requirements, commissioning tests, and whether the inverter's export-control and anti-islanding functions must be witnessed or retested at 60 Hz / 120-240 V. For commercial systems, confirm whether additional ODS, transmission-access, or regional-interconnection studies apply.[INFORMATIONAL] A Honduras distributed PV project needs a project-level CREE and ENEE/distributor acceptance path, not only a China inverter certificate. Confirm the autoproductor or interconnection route before selecting firmware settings, export-control functions, metering hardware, and commissioning tests.

IEC 62109-1 / IEC 62109-2 Safety Evidence — OHN / Project Acceptance Context China-side PV inverter safety evidence commonly includes GB/T 37408 and domestic voluntary certification or test reports. These materials are useful for baseline review but are not the same as an IEC 62109-1/-2 type-test certificate. A China certificate may also be tied to 50 Hz / 220-380 V default configuration, which needs separate review for Honduras 60 Hz / 120-240 V deployment.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 Honduras solar PV inverter projects, product safety evidence should be checked against OHN-recognised or project-specified standards and the requirements imposed by the owner, installer, insurer, lender, CREE/ENEE reviewer, or local authority. IEC 62109-1 and IEC 62109-2 are the core international safety standards for power converters and PV inverters. The safety file should identify the exact inverter model or family, ratings, environmental conditions, firmware/hardware configuration, and whether the certificate scope covers the intended Honduras 60 Hz / 120-240 V application.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
OHN (Organismo Hondureño de Normalización) standards adoption and project-owner acceptance to be confirmed for the specific project		 Gap: A China GB/T safety or technical-requirements report does not automatically satisfy an IEC 62109-1/-2 safety requirement in Honduras. Exporters should obtain or map IEC 62109-1/-2 certificates for the specific inverter model or family, check whether the issuing laboratory and certification body are acceptable to the buyer and local reviewer, and confirm that any Honduras firmware or grid-code configuration remains within the certified safety scope.[INFORMATIONAL] For Honduras, treat IEC 62109-1/-2 as the safety evidence package to confirm when a project, buyer, or reviewer requests international PV inverter safety certification. China GB/T evidence can support review but should not be presented as automatic OHN, CREE, ENEE, or project-owner acceptance. IEC (International Electrotechnical Commission)2026-06-14 · unverified
