CREG Regulatory Framework and Sonelgaz Grid-Connection Requirements China grid-connection evidence for PV inverters commonly cites GB/T 19964-2024 (technical requirements for PV power stations connecting to power systems) and GB/T 37408-2021. These standards address similar technical areas but are written for the Chinese 50 Hz grid and regulatory framework; they are not acceptable as Sonelgaz grid-connection documentation or CREG project-approval evidence for Algeria.GB/T 19964-2024
GB/T 37408-2021		 Algeria's electricity and gas sector is regulated by CREG (Commission de Régulation de l'Electricité et du Gaz), established under Law 02-01 on electricity and gas distribution. Sonelgaz (Société Nationale de l'Electricité et du Gaz) is the incumbent utility and distribution network operator; OS (Opérateur du Système) manages the national transmission grid and grid codes, with GRTE (Gestionnaire du Réseau de Transport de l'Electricité) responsible for the transmission network. Grid-connected PV inverters must comply with Sonelgaz technical connection specifications covering voltage and frequency ride-through, reactive-power management, anti-islanding protection, reconnection delay, power-quality requirements, and metering. Large-scale solar projects must obtain a generation licence from CREG. Algeria's Loi 04-09 (relative à la promotion des énergies renouvelables dans le cadre du développement durable) and subsequent decrees establish the legal basis for renewable energy generation and grid access.Loi 02-01 relative à l'électricité et à la distribution du gaz par canalisations (electricity and gas distribution law)

50 Hz Grid Frequency and Voltage Settings for Algeria Chinese PV inverters default to settings under GB/T 37408-2021 and GB/T 19964-2024 for the Chinese 50 Hz grid. While the nominal frequency matches Algeria, trip windows, reconnection sequences, reactive-power curve shapes, and active-power response ramps may differ from Sonelgaz or IEC expectations. Chinese inverters typically support multi-market grid profiles; firmware parameter adjustment for the Algeria market is necessary.GB/T 37408-2021
GB/T 19964-2024		 Algeria operates a 50 Hz grid with low-voltage nominal voltage of 230 V (single phase) and 400 V (three phase). The Algerian grid is synchronised with the Maghreb regional interconnection (COMELEC / RAEC / ELTAM) covering Morocco, Algeria, Tunisia, and Libya, which connects to the European ENTSO-E synchronous area via links to Spain and Italy. Inverters must be configured for 50 Hz operation with frequency ride-through, trip thresholds, reconnection delay, and reactive-power behaviour following Sonelgaz / OS technical rules and IEC practice. Chinese GB/T firmware defaults calibrated for the Chinese 50 Hz grid may differ in frequency and voltage tolerance bands from Sonelgaz requirements.Sonelgaz / OS technical grid-connection specifications for distributed and utility-scale PV

Algeria Solar Tender Programme and CREG / Ministry of Energy Market Access Chinese PV inverters exported to Algeria are classified under HS 8504.40 (static converters) for customs purposes. Chinese export documentation (CCC exemption letter, GB/T 37408-2021 test report, factory inspection certificate) is not a substitute for Algerian IANOR conformity attestation, CREG tender technical requirements, or Sonelgaz grid-connection approval. Local-content rules in Algerian tenders may require Chinese manufacturers to partner with Algerian entities or establish local assembly operations to qualify.HS 8504.40 (static converters, Chinese export classification)
GB/T 37408-2021 (Chinese PV inverter standard)		 Algeria has committed to large-scale solar capacity expansion through successive tender programmes. The Solar 1000 programme and follow-on tenders targeting 3 000–4 000 MW of solar PV capacity are managed by CREG and the Ministry of Energy and Mining. These tenders set project-specific technical specifications — typically referencing IEC standards for inverter safety, EMC, anti-islanding, and grid interconnection — and impose local-content rules (taux d'intégration nationale) that may require a percentage of project value to be sourced from Algerian manufacturers or assembled locally. Importers of PV inverters must comply with Algerian customs requirements including HS code classification, applicable import duties, and any conformity documentation required by the Ministry of Industry or IANOR. For utility-scale projects, a CREG generation licence is mandatory before construction.Loi 04-09 relative à la promotion des énergies renouvelables dans le cadre du développement durable

CN-DZ Trade and Preferential Tariff Context for Solar Inverters Chinese PV inverter exports to Algeria use standard export customs procedures under MOFCOM / GACC rules. China certificate of origin (Form A or self-certification) does not confer preferential tariff treatment in Algeria as no GSP or FTA rate applies for Chinese-origin goods under the Algerian tariff schedule as of 2026. Algeria has historically applied import restrictions and licensing regimes to manage foreign exchange and support domestic industry; exporters should confirm whether any specific import licence or foreign exchange pre-approval is required for the applicable product category.China MOFCOM / GACC export customs rules
Certificate of Origin (Form A or self-certification)		 Algeria has a trade and cooperation agreement with the European Union (the Euro-Mediterranean Association Agreement) and bilateral trade agreements with Arab League countries through the Greater Arab Free Trade Area (GAFTA). Algeria does not have a free trade agreement with China as of 2026. Standard import duties for HS 8504.40 static converters apply for Chinese-origin goods entering Algeria under the Most Favoured Nation (MFN) rate. The Algerian Customs authority (Direction Générale des Douanes — DGD) administers the tariff schedule and import controls. Algerian import regulations may include special import authorisation requirements or conformity attestation from IANOR for certain categories of electrical equipment. Importers should confirm the current MFN rate, value-added tax (TVA), and any parafiscal levies with the DGD or a licensed Algerian customs broker.Algerian Customs Tariff (DGD — Direction Générale des Douanes)

IANOR NA / IEC 62109 Inverter Safety Certification China solar PV inverter safety is governed by GB/T 37408-2021 (technical specification for PV grid-connected inverters) and supplementary NB/T 32004 or T/CPIA group standards. GB/T 37408-2021 covers protection and safety functions but is not identical in scope or test methodology to IEC 62109-1/2. A Chinese test report against GB/T 37408-2021 is not directly accepted by IANOR or an Algerian project owner or tender authority without supplementary IEC-route evidence.GB/T 37408-2021
NB/T 32004		 IANOR (Institut Algérien de Normalisation) is Algeria's national standardisation body, responsible for developing and adopting Algerian standards (NA prefix). Algeria adopts IEC standards as Algerian National Standards (NA) through the IANOR framework. Solar PV inverters are expected to meet IEC 62109-1 (safety for power converters — general requirements) and IEC 62109-2 (safety for PV inverters) as referenced in IANOR conformity and project procurement specifications. Algerian legislation on product conformity and technical regulation may require IANOR conformity attestation or an accepted third-party test report from an accredited laboratory against these standards before a product can be placed on the Algerian market or connected to the Sonelgaz grid. Large-scale solar project tenders (Solar 1000, follow-on programmes targeting 3 000–4 000 MW) typically require IEC-evidenced safety documentation as part of tender technical specifications.IEC 62109-1 as referenced in IANOR NA framework (safety for power converters — general requirements)

EMC and Anti-Islanding Requirements for PV Inverters in Algeria Chinese PV inverters are tested for EMC under GB/T 17626 series and GB 4824 (CISPR 11 equivalent), and for anti-islanding under GB/T 37408-2021 and NB/T 32004 which incorporate anti-islanding test methodologies. These Chinese test results give useful technical evidence but are not equivalent to IANOR NA / IEC 62920 or IEC 62116 certifications for the Algeria market. Chinese inverters exported to tender programmes will require IEC 62116 test certificates specifically.GB/T 17626 series
GB 4824
GB/T 37408-2021 (anti-islanding provisions)
NB/T 32004		 Algeria applies IEC-based electromagnetic compatibility (EMC) standards through IANOR NA adoption. Power conversion equipment including PV inverters should meet relevant IEC 62920 (EMC requirements for PV power generation systems) and IEC CISPR conducted and radiated emission limits. Anti-islanding protection must comply with IEC 62116 (utility-interconnected PV inverters — test procedure for islanding prevention measures). Sonelgaz and OS may specify additional EMC and protection requirements in their grid-connection technical specifications and project-specific requirements. Algeria's large-scale solar tender specifications (Solar 1000 programme and follow-on tenders) typically reference IEC EMC and anti-islanding standards as eligibility criteria.IEC 62920 (EMC requirements for PV power generation systems) as referenced via IANOR NA
