Compliance Gap Matrix

Gap matrix
Compliance item Common China baseline Tunisia (INNORPI / STEG / ANME) Gap / action Source + verification date
Tunisia 50 Hz Grid Compatibility China also uses 50 Hz, so nominal frequency is usually not the main gap. The gap is the allowed voltage and frequency windows, protection curves, anti-islanding trip settings, reactive power functions, export limitation logic, and the documented settings required by the Tunisian project.GB/T 19964-2024
GB/T 37408-2019
Factory grid-code profile for China		 Tunisia's electricity system uses 50 Hz, and STEG grid settings for PV connection should account for the cited 47.5-52 Hz frequency window and nominal-voltage tolerance of -15% / +10%. PV inverters for Tunisia should be configured and documented for the local voltage level, phase arrangement, protection thresholds, frequency ride-through or disconnection behavior, and STEG project settings.Tunisia 50 Hz public electricity system
STEG cited grid operating range: 47.5-52 Hz and nominal voltage -15% / +10%
STEG project-specific grid-connection settings
Applicable low-voltage or medium-voltage connection procedure		 Ship with a Tunisia-specific grid profile or a controlled commissioning process. Record firmware version, country code, protection settings, password control, and any field changes made by the installer or STEG-approved commissioning team.[INFORMATIONAL] Tunisia and China are both 50 Hz markets, but the exporter still needs Tunisia-specific STEG voltage and frequency settings, including the cited 47.5-52 Hz and -15% / +10% windows, plus commissioning evidence for the actual connection route.

ANME PV Program Lists and Eligible Installers Chinese supplier qualification lists, bankability files, and domestic installer approvals do not replace ANME or Tunisia project eligibility checks. They can be supporting evidence for supplier due diligence.Chinese supplier qualification file
Chinese installer or EPC qualification documents
Manufacturer bankability and warranty file		 ANME publishes PV program resources including accepted PV panel lists and eligible installer lists for grid-connected low-voltage and medium-voltage PV installations. These lists are not the same as a universal inverter type approval, but they show that Tunisia project eligibility can depend on current ANME program documents, eligible service providers, and project-file requirements.ANME PV downloads and current program lists
ANME eligible installers for grid-connected BT PV installations
ANME eligible installers for grid-connected MT PV installations		 Confirm whether the Tunisia buyer or program requires a named eligible installer, accepted product list, French warranty terms, local after-sales support, or ANME project documentation. Do not infer inverter eligibility from panel-list status.[INFORMATIONAL] ANME list status is project-context evidence, not a blanket inverter approval. Check the current program documents before quoting eligibility to a Tunisian buyer. Agence Nationale pour la Maîtrise de l'Energie (ANME)2026-06-14 · unverified
China GB/T Inverter Evidence Versus Tunisia Acceptance China evidence commonly includes GB/T 37408 for grid-connected photovoltaic inverters, GB/T 19964 for photovoltaic power-station grid connection, NB/T 32004-family technical specifications, EMC reports, and factory declarations. These documents should be treated as input evidence, not automatic Tunisia approvals.GB/T 37408-2019
GB/T 19964-2024
NB/T 32004 series		 Tunisia-facing evidence should be organized around the Tunisian project route, IEC / NT standards, STEG connection review, and ANME program requirements. China GB/T standards can be useful technical evidence, but they do not by themselves prove Tunisian conformity unless the reviewer accepts them or a clause-by-clause equivalence file is approved.IEC 62109-1 / IEC 62109-2 where required
Applicable INNORPI NT standards
STEG / ANME project procedures		 Create a matrix that maps each GB/T or NB/T test item to the requested IEC, NT, STEG, ANME, tender, or contract clause. Mark unsupported clauses clearly and close them with additional IEC reports, lab statements, firmware setting records, or project tests.[INFORMATIONAL] Use China GB/T reports as mapped technical evidence, not as a substitute for Tunisia project approval, IEC / NT evidence, or STEG / ANME review.

STEG / ANME Grid-Connection Review for PV Self-Production China grid-connection reports and factory settings are usually based on Chinese grid codes and buyer specifications. They should be reconfigured and documented for Tunisia's STEG connection study, protection settings, anti-islanding behavior, voltage and frequency windows, and commissioning tests.GB/T 19964-2024
GB/T 37408-2019
Project-specific Chinese grid-code settings		 Grid-connected PV projects in Tunisia must follow the applicable STEG connection and tariff procedures and ANME program or eligibility route. For low-voltage (BT) PV self-production, the cited Tunisia route uses a 200 kWc capacity limit and a 40 kWc threshold above which a STEG technical study is required. STEG also publishes renewable-energy autoproductor procedures, and ANME publishes PV resources and lists for grid-connected BT and MT installations.STEG renewable-energy autoproductor tariff and procedure pages
Tunisia BT PV self-production route: 200 kWc capacity limit and STEG technical study above 40 kWc
STEG simplified procedure for renewable-energy autoproducteurs connected to the medium-voltage network
ANME PV resources for grid-connected BT and MT installations		 Prepare a Tunisia-specific grid file: single-line diagram, inverter certificates, protection relay settings, anti-islanding evidence, power-quality data, commissioning protocol, French technical documents where requested, and a settings lock or change-control record for the deployed firmware.[INFORMATIONAL] A China grid certificate is not a Tunisia grid-connection approval. For BT PV, check the 200 kWc capacity limit and the 40 kWc STEG study threshold, and treat STEG / ANME review, project settings, and commissioning evidence as separate deliverables.

INNORPI NT Standards and Project-Specified Standards Chinese exporters often provide GB/T or NB/T reports, CQC files, and IEC CB reports. The Tunisia file should identify which documents are direct IEC evidence and which are China-specific evidence requiring equivalence review.GB/T 37408-2019
NB/T 32004 series where used by buyer or project
IEC CB test report and certificate where available		 INNORPI is Tunisia's national standards body and may adopt Tunisian NT standards based on international standards. For solar PV inverters, exporters should verify whether the tender, customs route, conformity route, STEG connection file, or project owner cites VDE 0126-1-1 certification, NT 67.74 for EMC, NT 87.47-7-712 for PV electrical installations, IEC 62109, or other PV, EMC, low-voltage, or grid standards. A standard may be voluntary in general but mandatory once referenced by regulation, procurement, connection approval, or contract.Applicable Norme Tunisienne (NT) standards published or adopted by INNORPI
STEG-cited VDE 0126-1-1 inverter certificate where required
NT 67.74 for electromagnetic compatibility where required
NT 87.47-7-712 for photovoltaic electrical installations where required
IEC 62109-1 / IEC 62109-2 where adopted, cited, or contractually required
Project-specific tender or procurement specifications		 Before shipment, request the buyer's exact NT / IEC list and check whether INNORPI, customs, utility, financing, or project procurement requires original certificates, French documentation, Arabic / French labels, or local conformity steps.[INFORMATIONAL] Treat INNORPI / NT applicability as a scope question, not a guess. The export file should name each VDE, NT, or IEC item required by the Tunisian project, including VDE 0126-1-1, NT 67.74, and NT 87.47-7-712 where cited, and show how China evidence maps to it.

Renewable-Energy Self-Production Route Under Law 2015-12 Chinese domestic distributed-PV filing, grid-connection, and subsidy documents do not establish the Tunisian legal route. They may support project references but should not be presented as proof of Tunisian self-production authorization.Chinese distributed PV filing and grid-connection documents
GB/T 19964-2024
GB/T 37408-2019		 Tunisia's renewable-electricity framework includes Law 2015-12 on electricity production from renewable energies. PV self-production projects should confirm the applicable regime, authorization or declaration route, surplus-sale treatment, STEG contract or tariff handling, ANME involvement, and whether the inverter documentation is part of the technical file for the project rather than a standalone market-access approval.Tunisia Law 2015-12 on electricity production from renewable energies
STEG tariffs for renewable-energy surplus purchase
ANME renewable-energy and PV program documentation		 For a Tunisia project, confirm whether the legal route is self-consumption, self-production with surplus sale, authorization, concession, or another project category. The inverter supplier should provide technical documents in a format the developer can attach to the STEG / ANME / authority file.[INFORMATIONAL] Law 2015-12 is a project-route issue. The inverter file should support the Tunisian self-production or surplus-sale application, not imply automatic legal authorization.

PV Inverter Electrical Safety: IEC 62109 Evidence China suppliers may hold IEC 62109 CB reports, GB/T inverter reports, or manufacturer declarations. These can support the Tunisia file, but Chinese domestic reports should be cross-mapped to the exact IEC or NT clauses requested by the buyer, utility, or tender.IEC 62109 CB Scheme test report where available
GB/T 37408-2019
Manufacturer declaration of conformity		 Tunisia projects and tenders commonly need inverter safety evidence aligned with international PV inverter standards. IEC 62109-1 covers general safety requirements for PV power conversion equipment, and IEC 62109-2 covers particular requirements for inverters. Whether the evidence is legally mandatory depends on the import route, INNORPI-adopted NT standard scope, tender documents, utility review, financing conditions, and project owner requirements.IEC 62109-1:2010
IEC 62109-2:2011
Applicable INNORPI-adopted NT standards where specified by project or authority		 Do not assume a China GB/T test report is accepted as-is. Prepare IEC 62109-1 and IEC 62109-2 certificates or test reports, model-family coverage, critical component lists, installation manual, nameplate ratings, and a clause mapping for any China-only evidence.[INFORMATIONAL] IEC 62109 evidence is the safest baseline for Tunisia-facing inverter files, but it should be tied to the specific Tunisian project, tender, INNORPI / NT reference, and STEG / ANME review route.
