EMC — IEC 62920 and IEC 61000-3-2 for PV Inverters — ANOR PECAE Conformity and Donor/Lender Procurement Chinese PV inverter EMC is assessed under GB/T 37408-2021 (Technical Requirements for Photovoltaic Grid-Connected Inverters), which includes EMC test requirements aligned with China's domestic framework. GB/T 37408 EMC testing is conducted at CNAS-accredited Chinese laboratories. While IEC 62920 draws on IEC 61000-series test methods that are also referenced in Chinese domestic standards, the GB/T 37408 EMC test scope and referenced emission limits are not harmonised with IEC 62920 and IEC 61000-3-2 as applied in ANOR PECAE conformity assessment. Chinese EMC certificates based solely on GB/T 37408 are not accepted as IEC 62920 or IEC 61000-3-2 compliance evidence for ANOR PECAE or donor/lender procurement submissions in Cameroon.GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters) — includes EMC test requirements based on China's domestic framework ANOR adopts IEC standards as its technical reference for PV equipment EMC conformity under the PECAE pre-shipment programme. The primary EMC standards applicable to solar PV inverters are: IEC 62920 (Photovoltaic power generating systems — EMC requirements and test methods for power conversion equipment), which is the dedicated EMC standard for PV power conversion equipment covering both conducted and radiated emissions, immunity, and test methods; and IEC 61000-3-2 (Electromagnetic compatibility — Limits for harmonic current emissions for equipment with input current up to and including 16 A per phase), which sets harmonic current emission limits relevant to smaller inverters connected at the distribution level. Cameroon's distribution network operates at 230/400 V, 50 Hz (ENEO). No standalone ANOR Technical Regulation specifically targeting solar inverter EMC has been publicly identified; EMC evidence for ANOR PECAE is assessed against IEC-referenced requirements embedded in the PECAE conformity framework. Donor/lender-funded solar projects (AfDB, World Bank, EU) in Cameroon also reference IEC 62920 and IEC 61000-3-2 as procurement technical requirements for inverter supply.IEC 62920 — Photovoltaic power generating systems — EMC requirements and test methods for power conversion equipment (IEC standard adopted by ANOR as technical reference for PV EMC conformity)

ANOR PECAE — Programme d'Évaluation de la Conformité Avant Embarquement — IEC-referenced EMC evidence required for Certificate of Conformity		 Chinese GB/T 37408 EMC testing does not satisfy ANOR PECAE's IEC 62920 and IEC 61000-3-2 requirements for Cameroon. Exporters should obtain: (a) IEC 62920 EMC type-test report from an ILAC-accredited laboratory covering the specific inverter model and power rating; (b) IEC 61000-3-2 harmonic current emission test report for the specific model. Where harmonic emission test results were obtained under Chinese grid conditions (220/380 V), consider whether retesting under Cameroon's grid voltage conditions (230/400 V, 50 Hz) is required by the ANOR-appointed inspection body or the project's donor/lender technical specification. EMC test reports and technical documentation should be provided in both French and English consistent with Cameroon's official bilingual administrative requirements.[INFORMATIONAL] Chinese GB/T 37408 EMC certificates do not satisfy ANOR PECAE's IEC 62920 and IEC 61000-3-2 requirements for Cameroon. Obtain IEC 62920 and IEC 61000-3-2 type-test reports from an ILAC-accredited laboratory for the specific inverter model before submitting for ANOR PECAE pre-shipment conformity assessment. Confirm whether Cameroon's grid voltage conditions (230/400 V) require retesting compared to test results obtained under China's 220/380 V grid conditions. Provide all technical documentation in both French and English. Verify current ANOR PECAE requirements and the appointed inspection body for Cameroon directly with ANOR before committing to a test programme.

ANOR PECAE Pre-Shipment Conformity — Grid-Connection and Anti-Islanding (IEC 62116, IEC 61727) for 230/400 V, 50 Hz Chinese grid-connection evidence commonly provided includes GB/T 19964-2024 (Technical Requirements for Connecting Photovoltaic Power Station to Power System, applicable to utility-scale PV via 10 kV and above), NB/T 32004 (inverter technical specifications), and domestic anti-islanding test results obtained under Chinese grid conditions. These Chinese grid-connection documents are based on China's domestic grid parameters (220/380 V, 50 Hz under GB/T 156) and are not accepted by ANOR as equivalent to IEC 62116 or IEC 61727 type-test evidence for PECAE conformity purposes. The voltage difference between China (220/380 V) and Cameroon (230/400 V) at the same 50 Hz frequency means firmware protection thresholds validated for Chinese grid conditions must be re-parameterised and retested for Cameroon's 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)
GB/T 156 — 标准电压 (Standard voltages) — China domestic grid: 220/380 V at 50 Hz
NB/T 32004-2018 — 光伏并网逆变器技术规范 (Technical Specification for Photovoltaic Grid-Connected Inverters)		 Cameroon's national standards body ANOR (Agence des Normes et de la Qualité) administers the PECAE programme (Programme d'Évaluation de la Conformité Avant Embarquement — Pre-Shipment Conformity Assessment Programme). Under PECAE, regulated electrical and electronic products, including solar PV equipment, require a Certificate of Conformity (CoC) issued by an ANOR-appointed inspection body before export to Cameroon. ANOR adopts IEC standards as its primary technical reference for PV equipment. For grid-connected PV inverters, the relevant IEC grid standards are: IEC 62116 (Utility-interconnected photovoltaic inverters — Test procedure of islanding prevention measures), requiring inverters to detect loss of mains and disconnect within 2 seconds maximum; and IEC 61727 (Photovoltaic systems — Characteristics of the utility interface), which sets interface requirements including voltage and frequency operating windows. Cameroon's national grid operates at 230 V single-phase and 400 V three-phase at 50 Hz (ENEO / SONATREL distribution and transmission network). Inverter firmware protection thresholds and reconnection delays must be validated for Cameroon's 230/400 V, 50 Hz grid, not the 220/380 V, 50 Hz settings used in China under GB/T 156.IEC 62116 — Utility-interconnected photovoltaic inverters — Test procedure of islanding prevention measures (IEC standard adopted by ANOR as technical reference for PV conformity)

ARSEL sector regulation — licensing requirements for grid-connected power generation and distribution installations in Cameroon
ENEO / SONATREL grid parameters — 230 V single-phase, 400 V three-phase, 50 Hz (Cameroon national grid)		 Gap: Chinese GB/T grid-connection documents do not satisfy ANOR PECAE conformity requirements for Cameroon. For grid-tied PV inverters, exporters must prepare: (a) IEC 62116 anti-islanding type-test report from an ILAC-accredited laboratory; (b) IEC 61727 interface compliance evidence; (c) firmware protection thresholds and reconnection delays validated for Cameroon's 230/400 V, 50 Hz grid — not the 220/380 V China grid parameters; (d) ARSEL sector licensing confirmation for the installation; (e) ENEO grid-connection approval for distribution-level projects. For off-grid or mini-grid projects (common under Cameroon's AER rural electrification programme or donor-funded schemes), grid-connection approvals may be replaced by donor/lender technical specifications (AfDB, World Bank, EU), which typically reference IEC standards independently and require ILAC-accredited test evidence. Where inverter firmware settings differ from the China factory default, re-parameterisation must be documented and, if the change is material, retested under the applicable IEC standard.[INFORMATIONAL] Cameroon requires ANOR PECAE pre-shipment conformity (IEC-referenced evidence) before export, ARSEL sector licensing for grid-tied installations, and ENEO grid-connection approval for distribution-level projects. Chinese GB/T grid certificates do not satisfy any of these gates. Re-parameterise inverter firmware for Cameroon's 230/400 V, 50 Hz grid and obtain IEC 62116 and IEC 61727 type-test reports from an ILAC-accredited laboratory before shipment. For donor/lender-funded mini-grid or solar projects, verify IEC certification requirements in the specific procurement specification before committing equipment.

ARSEL Licensing and ENEO / SONATREL Grid-Connection — Distributed and Utility-Scale PV in Cameroon China does not have a direct equivalent to Cameroon's ARSEL licensing or ENEO grid-connection approval process. Distributed solar connection in China is governed by National Energy Administration (NEA) distributed PV policies and grid operator (State Grid, Southern Power Grid) connection rules, referencing China domestic standards (NB/T 32004, GB/T 37408, GB/T 19964-2024). Chinese distributed or utility-scale connection approvals under NEA rules are not applicable in Cameroon and do not give any presumption of compliance with ARSEL licensing or ENEO grid-connection technical requirements.NB/T 32004-2018 — 光伏并网逆变器技术规范 (Technical Specification 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)		 ARSEL (Agence de Régulation du Secteur de l'Électricité) is Cameroon's electricity sector regulator and issues licences for power generation, distribution, and sales activities, including grid-connected solar PV installations. ENEO (Energy of Cameroon) is the main distribution concessionaire and manages grid-connection approvals for distribution-level connections; SONATREL (Société Nationale de Transport de l'Électricité) manages the high-voltage transmission network. For grid-connected PV projects — whether distributed rooftop or utility-scale — ARSEL licensing and ENEO connection approval are mandatory regulatory gates. Equipment technical specifications submitted for ARSEL and ENEO review must meet IEC-referenced requirements. Cameroon has a hydro-dominant generation mix (Sanaga basin: Songloulou, Edéa, Lom Pangar), with solar PV primarily deployed through: (a) donor/IPP utility-scale projects (e.g. Scatec, Release Maroua-Guider corridor); (b) AER (Agence d'Électrification Rurale) off-grid and mini-grid rural electrification programmes; (c) C2D / EU-funded decentralised solar schemes. All grid-tied inverters for these categories must carry IEC-conformant documentation acceptable to ARSEL and ENEO.ARSEL — Agence de Régulation du Secteur de l'Électricité — Cameroon electricity sector licensing authority

Chinese grid-connection approvals do not transfer to Cameroon. Confirm inverter IEC compliance evidence (IEC 62116, IEC 61727, IEC 62109-1/-2, IEC 62920), firmware settings validated for 230/400 V at 50 Hz, bilingual (French/English) technical documentation, and equipment eligibility with the relevant ARSEL-licensed contractor and ENEO project review team before committing product. For AER rural electrification or donor-funded mini-grid projects, confirm the applicable technical specification in the project financing or procurement documents — donor requirements may be more stringent than or different from base ARSEL/ENEO requirements.[INFORMATIONAL] ARSEL licensing and ENEO grid-connection approval are separate and mandatory regulatory gates from any Chinese domestic solar approval. Confirm inverter IEC compliance evidence and firmware settings for Cameroon's 230/400 V, 50 Hz grid, and verify ARSEL licensing status and ENEO connection requirements with the project team before submitting equipment for project review. For donor/lender-funded projects, read the specific procurement technical specification — IEC certification requirements may exceed the base ARSEL/ENEO level.

IEC 62109-1 / IEC 62109-2 Safety Evidence — ANOR PECAE Pre-Shipment Conformity and ARSEL / ENEO Project Approval China's primary standard for PV grid-connected inverter safety is GB/T 37408-2021 (Technical Requirements for Photovoltaic Grid-Connected Inverters, 2021 revision), which covers classification, environmental conditions, safety, electrical performance, EMC, and markings. GB/T 37408 safety testing is conducted at CNAS-accredited Chinese laboratories. While GB/T 37408 shares conceptual safety intent with IEC 62109-1/-2, it is not harmonised with IEC 62109 and is not accepted by ANOR as equivalent to IEC 62109 type-test evidence for PECAE conformity purposes. Donor/lender procurement specifications for Cameroon solar projects do not recognise Chinese GB/T 37408 certificates as equivalent to IEC 62109-1/-2 type-test evidence.GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters, 2021 revision) ANOR adopts IEC standards as the technical reference framework for PV equipment conformity assessment under the PECAE pre-shipment programme. For solar PV inverters, the primary safety standards referenced by ANOR for conformity purposes are IEC 62109-1 (Safety of power converters for use in photovoltaic power systems — Part 1: General requirements) and IEC 62109-2 (Part 2: Particular requirements for inverters). These standards address electrical safety, thermal protection, mechanical integrity, and protection against environmental hazards for inverter equipment. Third-party type-test evidence from an ILAC-accredited laboratory is required for ANOR PECAE Certificate of Conformity issuance for regulated PV products. Additionally, donor/lender-funded projects (AfDB, World Bank, EU) in Cameroon's solar sector consistently require IEC 62109-1/-2 type-test certification as a procurement condition for inverter supply. Bilingual (French/English) documentation is required, reflecting Cameroon's official bilingual status.IEC 62109-2 — Safety of power converters for use in photovoltaic power systems — Part 2: Particular requirements for inverters (primary IEC safety standard adopted by ANOR for PV inverter conformity)

ANOR PECAE — Programme d'Évaluation de la Conformité Avant Embarquement (Cameroon pre-shipment conformity assessment — IEC-referenced safety evidence required for CoC)		 Chinese GB/T 37408 safety certification does not satisfy ANOR PECAE's IEC 62109-1/-2 type-test requirement for Cameroon. Exporters must obtain IEC 62109-1/-2 type-test certificates from an ILAC-accredited laboratory covering the specific inverter model or family being supplied to the Cameroon project. Existing Chinese safety certificates based solely on GB/T 37408 must be supplemented with IEC 62109-1/-2 test reports before submitting equipment documentation for ANOR PECAE conformity assessment or ARSEL/ENEO project review. Technical documentation submitted to ANOR, ARSEL, and ENEO should be available in both French and English, consistent with Cameroon's official bilingual administrative requirements.[INFORMATIONAL] A solar PV inverter holding only Chinese GB/T 37408 safety certification cannot satisfy ANOR PECAE's IEC 62109-1/-2 conformity requirement for Cameroon. Plan for IEC 62109-1/-2 type testing by an ILAC-accredited laboratory before submitting equipment for ANOR PECAE pre-shipment conformity assessment or ARSEL/ENEO project review. Prepare technical documentation in both French and English. Verify current ANOR PECAE product scope, the appointed inspection body for Cameroon, and model-family coverage requirements directly with ANOR before committing to a test programme.
