Compliance Gap Matrix

Gap matrix
Compliance item Common China baseline United Arab Emirates (ESMA ECAS / DEWA) Gap / action Source + verification date
50 Hz 230/400 V Grid Re-Validation Against UAE Utility Settings China baseline files often use GB/T 37408, GB/T 19964, NB/T 32004, and domestic utility profiles. They are not proof that UAE trip settings, reconnection timing, harmonic limits, or commissioning evidence are correct for DEWA or another emirate utility.GB/T 37408
GB/T 19964
NB/T 32004		 DEWA eligibility and DRRG documentation require inverter evidence to align with the relevant connection category and DEWA compliance tests. Even where China test files show 50 Hz operation, UAE deployment should re-check voltage/frequency windows, trip thresholds, reconnection timing, power-quality limits, harmonic spectrum data, low-voltage or medium-voltage category, and local nameplate settings for 230/400 V distribution practice and the project utility's approved parameters.DEWA DRRG Standards - Version 3.0 - December 2023
DEWA PV inverter eligibility requirement for harmonic spectrum data
Project-specific utility connection approval and commissioning evidence
IEC 61000-2-2 and IEC/TR 61000-3-14 voltage-quality references listed by DEWA for LV-connected RRGPs		 The technical gap is firmware profile control and evidence traceability. Exporters should lock the UAE grid profile, document country code or parameter settings, provide harmonic spectrum data for the exact model, and prepare commissioning checks that match the utility's accepted values.[INFORMATIONAL] Re-validate the UAE grid profile rather than shipping with China default settings. DEWA and project utility files should show the exact inverter model, firmware profile, harmonic data, and commissioning settings. Dubai Electricity and Water Authority (DEWA)2026-06-13 · unverified
DEWA DRRG Grid Connection, Anti-Islanding, and Utility-Interface Evidence China grid evidence commonly references GB/T 19964, GB/T 37408, NB/T 32004, utility test reports, and domestic anti-islanding settings. These can support a technical delta review but do not replace DEWA DRRG equipment enrollment, project connection conditions, inspection, or commissioning files.GB/T 19964
GB/T 37408
NB/T 32004		 DEWA Shams Dubai relies on DRRG standards, connection conditions, connection guidelines, inspection and testing requirements, and eligible equipment lists for distributed renewable resource generators. For PV inverters, DEWA minimum eligibility points to the DRRG Standards Version 3.0, December 2023, including inverter compliance tests for low-voltage and/or medium-voltage connected RRGPs. Anti-islanding and utility-interface evidence should be prepared in the DEWA DRRG context rather than treated as a generic China grid certificate.DEWA DRRG Standards - Version 3.0 - December 2023
DEWA DRRG Connection Conditions
DEWA DRRG Connection Guidelines - Version 2.1 - March 2024
DEWA DRRG Inspection and Testing Guidelines - Version 2.0 - April 2020
IEC 62116 and IEC 61727 as common anti-islanding and utility-interface evidence where requested by project or utility review		 The gap is project and utility acceptance: the inverter evidence must be aligned with the relevant DEWA appendix, low-voltage or medium-voltage connection category, protection settings, reconnection behavior, harmonic evidence, and commissioning sequence.[INFORMATIONAL] Treat DEWA DRRG review as a separate utility gate. IEC 62116 / IEC 61727 and China GB/T grid files are useful only when mapped to the DEWA connection category and project file. Dubai Electricity and Water Authority (DEWA)2026-06-13 · unverified
MoIAT / ESMA ECAS and EQM Scope Screening for PV Inverters China commonly has GB-standard and voluntary CQC/CGC evidence for PV inverters, but those files do not by themselves establish UAE ECAS scope, EQM mark eligibility, or DEWA equipment eligibility. A UAE product-status and utility-route check is still needed.GB/T 37408
GB/T 19964
NB/T 32004		 UAE conformity services include certificates for products subject to technical regulations, certificates for products not subject to technical regulations, attestation of GSO conformity certificates, national conformity marks, and product status services. For solar PV inverters, ECAS certification is mandatory under UAE Cabinet Decision No. 10 of 2020, the UAE Control System for Solar Products, administered by MoIAT. EQM, DEWA, or another emirate utility process may still apply separately depending on the model, mark route, customer requirement, project, or connection authority.MoIAT conformity certificate services for products subject to technical regulations
MoIAT conformity certificate services for products not subject to technical regulations
MoIAT national marks services and product status services
UAE Cabinet Decision No. 10 of 2020 - UAE Control System for Solar Products, administered by MoIAT
Attestation of GSO conformity certificates where applicable		 The market-access gap is ECAS file readiness and route selection. Exporters should prepare model family lists, nameplate ratings, HS code, intended emirate and use case, existing IEC/CB/GB reports, and local representative details for MoIAT/ESMA and utility review.[INFORMATIONAL] Treat ECAS as mandatory for solar PV inverters under UAE Cabinet Decision No. 10 of 2020 and prepare the MoIAT conformity file accordingly. DEWA eligibility and project approval are separate from federal conformity services. UAE Ministry of Industry and Advanced Technology (MoIAT)2026-06-13 · unverified
IEC 62109-1 / IEC 62109-2 Safety Evidence for DEWA PV Inverter Eligibility China GB-standard safety files and voluntary CQC/CGC reports may support engineering review, but DEWA's listed route requires the submitted compliance certificate to match the relevant DEWA eligibility criteria. A China-only report should be mapped to IEC 62109-1/-2 or supplemented with an accepted IEC/UL report.GB/T 37408
NB/T 32004
CQC or CGC voluntary PV inverter certification		 DEWA states that PV inverter minimum eligibility depends on compliance to IEC 62109-1/2 or UL 1741, with mandatory compliance certificates issued by third-party ILAC-accredited laboratories according to ISO/IEC 17025. For Dubai Shams Dubai projects, this makes inverter safety type-test evidence a practical eligibility gate before the model can be added to the DEWA eligible equipment route.IEC 62109-1
IEC 62109-2
UL 1741 as an alternative listed by DEWA
ISO/IEC 17025 and ILAC-accredited laboratory certificate expectation		 The gap is not just the standard number. DEWA expects certificate evidence from an ILAC-accredited laboratory, model coverage consistent with the application, and clear linkage to the inverter family being enrolled.[INFORMATIONAL] For Dubai projects, prepare IEC 62109-1/-2 or UL 1741 evidence from an ILAC-accredited lab before DEWA equipment enrollment. Treat this as separate from any federal UAE conformity certificate. Dubai Electricity and Water Authority (DEWA)2026-06-13 · unverified
UAE.S / GSO Standards Adoption and EMC Evidence China EMC reports can be useful if they test equivalent IEC 61000 clauses and the model configuration is identical. They should still be checked against UAE.S/GSO adoption status, DEWA wording, laboratory accreditation, and the declared residential, commercial, light-industrial, or industrial environment.GB/T 37408
GB/T 17626 series
GB 4824 or GB/T 17799 series where applicable		 MoIAT describes digital standards services that enable purchase of UAE and GSO standards, and GSO maintains a standards store with GSO IEC adoptions. DEWA's PV inverter minimum eligibility lists EMC-related requirements including IEC 61000-3-2 or IEC 61000-3-12 and one of the IEC 61000-6-x immunity/emission combinations depending on environment category. For UAE projects, exporters should confirm whether a UAE.S or GSO adoption, DEWA-specific certificate wording, or project contract controls the submitted EMC evidence.UAE and GSO standards services
GSO IEC standards adoption route
IEC 61000-3-2 or IEC 61000-3-12
IEC 61000-6-1 / IEC 61000-6-3
IEC 61000-6-2 / IEC 61000-6-4
IEC 61000-6-2 / IEC 61000-6-3		 The gap is evidence alignment: the EMC report must match the inverter model, firmware or hardware configuration, intended use environment, and UAE/DEWA wording. A report against a China-only GB test plan may need a clause-by-clause IEC/UAE.S/GSO mapping or re-test.[INFORMATIONAL] Verify the current UAE.S/GSO adoption and DEWA certificate wording before relying on China EMC reports. EMC is often a documentation delta even when the underlying IEC tests are similar. UAE Ministry of Industry and Advanced Technology (MoIAT)2026-06-13 · unverified
