GAP MATRIX

Compliance Gap Matrix

Gap matrix
Compliance item Common China baseline Vietnam (MOIT / TCVN / EVN) Gap / action Source + verification date
50 Hz Grid Re-Validation vs China GB/T 37408 / GB/T 19964 Baseline The common China baseline includes GB/T 37408-2019 for grid-connected PV inverter technical requirements and GB/T 19964-2024 for PV power-station access to the power system. These documents are a strong starting point for engineering comparison but are not Vietnam grid approval documents.GB/T 37408-2019
GB/T 19964-2024		 Vietnam uses a 50 Hz electricity system, but a China 50 Hz inverter configuration should still be re-validated against the Vietnam project grid-code settings, voltage level, protection windows, reconnection timing, ride-through settings, harmonic limits, and EVN commissioning requirements. Passing the China baseline does not automatically prove the final Vietnam firmware profile is acceptable.Vietnam MOIT electricity-system rules for the applicable voltage level
EVN project commissioning and interconnection requirements
Project-specific grid-code settings		 Prepare a Vietnam parameter file rather than shipping a generic China setting. Evidence should tie the hardware, firmware, country code, anti-islanding logic, protection thresholds, and commissioning test records to the actual Vietnam site or project class.[INFORMATIONAL] A 50 Hz China profile is only a baseline. Re-validate the inverter with Vietnam project settings before grid approval or commissioning. Vietnam Electricity (EVN)2026-06-13 · unverified
EMC and Radio-Module Scope for Connected Inverters China-origin packages may include GB/T 17626 immunity reports, GB 17625 harmonic or flicker reports, SRRC approvals for radio modules, and CE EMC reports. These documents can support engineering review but do not automatically satisfy Vietnam QCVN, MIC, label, or project-specific acceptance requirements.GB/T 17626 series
GB 17625 series
SRRC radio transmission equipment approval
CE EMC test reports		 Vietnam EMC obligations for a PV inverter depend on the exact product scope and any communications functions. A base power-conversion unit, a gateway-equipped inverter, and an inverter with embedded Wi-Fi, cellular, Bluetooth, or other radio modules may fall into different technical-regulation, conformity, labeling, or radio approval paths. Confirm the current Vietnam QCVN / MIC / project scope before relying on China EMC or radio reports.Applicable Vietnam QCVN EMC technical regulations by product scope
Vietnam MIC radio equipment rules where intentional transmitters are included
Project EMC and power-quality specifications where imposed by owner or utility		 Classify each SKU separately. The gap is often in the communications variant, external gateway, antenna, firmware, label, user notice, and local representative evidence rather than the power stage alone. Prepare a Vietnam scope memo before import or project submission.[INFORMATIONAL] Treat EMC and radio-module compliance as a separate Vietnam scope check for each inverter SKU and communications configuration.

MOIT and EVN Grid Connection Code and Anti-Islanding Evidence Chinese documentation often includes GB/T 37408-2019 inverter technical requirements, GB/T 19964-2024 PV power-station grid connection requirements, and IEC 62116 / IEC 61727 reports. These are useful baseline documents but must be re-mapped to Vietnam's connection study, relay settings, voltage/frequency windows, and EVN acceptance process.GB/T 37408-2019
GB/T 19964-2024
IEC 62116
IEC 61727		 Grid-tied PV inverter projects in Vietnam must be reviewed against the applicable MOIT electricity-system rules and the EVN interconnection route for the actual voltage level and project type. Anti-islanding evidence may be requested through IEC 62116, IEC 61727, or project-specific technical specifications, but the enforceable obligation comes from the applicable grid-connection approval and electricity-system rules rather than from the IEC standards by themselves.MOIT electricity transmission and distribution system regulations
EVN interconnection procedures for grid-connected generation
IEC 62116 anti-islanding test procedure
IEC 61727 photovoltaic systems utility interface		 The practical gap is the project-specific interconnection package. Exporters should prepare inverter type-test reports, anti-islanding test evidence, grid-code parameter tables, protection settings, firmware version controls, harmonic and power-quality data, and site commissioning records in a form EVN or the project reviewer can trace to the actual model and settings.[INFORMATIONAL] Treat anti-islanding and grid-code evidence as a Vietnam project approval workstream, not as a generic IEC report handover.

Rooftop Solar, DPPA, and Self-Consumption Rules China-origin documentation may describe Chinese distributed PV project filings, self-consumption/export settings, grid-dispatch settings, and Chinese owner acceptance records. These documents can explain the product configuration but do not establish eligibility under Vietnam's rooftop-solar, DPPA, or EVN interconnection route.China distributed PV project filing documents
China self-consumption / export-control settings
China owner acceptance records		 Vietnam's current rooftop-solar compliance route depends on the project model. Decree 80/2024/ND-CP created a direct power purchase mechanism for renewable-energy generators and large electricity users, while Decree 135/2024/ND-CP addresses mechanisms and policies for self-produced, self-consumed rooftop solar power. EVN's 2026 public guidance continues to frame rooftop solar as self-produced, self-consumed project development and points users to current Government and MOIT procedures. The inverter file should therefore be matched to whether the installation is behind-the-meter self-consumption, excess-power arrangement, DPPA-related generation, or another grid-connected project route.Decree 80/2024/ND-CP
Decree 135/2024/ND-CP
Applicable MOIT / EVN implementation procedures for the project model
EVN rooftop-solar public guidance, 12-Jun-2026		 The commercial model changes the compliance package. For Vietnam, confirm whether the inverter needs export-limitation controls, metering interfaces, remote dispatch or telemetry, project registration documents, cybersecurity or communications evidence, and local owner declarations tied to the specific rooftop or DPPA route. The proposed Decision 1570/QD-EVN (2024) SCADA/monitoring requirement for systems >=100 kW could not be verified from official sources, so do not treat that exact decision number or threshold as confirmed without fresh EVN confirmation.[INFORMATIONAL] Classify the Vietnam project route before finalizing inverter settings and documents; rooftop self-consumption and DPPA files are not interchangeable, and the proposed Decision 1570/QD-EVN >=100 kW SCADA threshold remains unverified.

TCVN Adoption of IEC 62109-1/-2 Inverter Safety China-origin inverter files commonly include IEC CB reports to IEC 62109-1/-2, CQC or CGC voluntary certificates, and China project safety evidence. These can support Vietnam review, but the Vietnam-facing package should map the report editions and national deviations to the current TCVN / project requirement.IEC 62109-1 CB Scheme report
IEC 62109-2 CB Scheme report
CQC / CGC voluntary PV inverter certification		 Vietnamese project files for PV inverters may request safety evidence aligned to TCVN 12231-1:2018 and TCVN 12231-2:2018, the Vietnamese adoptions corresponding to IEC 62109-1 and IEC 62109-2 for power converters used in photovoltaic power systems. Treat the TCVN / IEC evidence as a technical safety dossier item unless a specific tender, grid-connection approval, import program, or legal instrument makes it mandatory for the transaction. A proposed mandatory energy-efficiency-labeling claim for PV inverters under MOIT Circular 12/2026/TT-BCT and TCVN 8929:2026 effective 1-Jun-2026 could not be verified from official sources, so it is not treated here as a confirmed requirement.TCVN 12231-1:2018
TCVN 12231-2:2018
IEC 62109-1
IEC 62109-2		 The gap is not only whether IEC 62109 testing exists, but whether the Vietnamese buyer, utility reviewer, or project owner accepts the edition, certificate holder, factory address, model family, and Vietnamese documentation crosswalk. Prepare a TCVN-to-IEC clause matrix, model list, critical component list, labels, manuals, and any Vietnamese-language declarations requested by the project.[INFORMATIONAL] Do not assume an IEC 62109 CB report alone closes the Vietnam safety file, and do not rely on the unverified Circular 12/2026/TT-BCT + TCVN 8929:2026 labeling claim without official confirmation. Crosswalk evidence to the current TCVN / project requirement and confirm acceptance with the buyer or approving party. Vietnam Standards and Quality Institute (VSQI) / STAMEQ2026-06-13 · unverified
