GAP MATRIX
Compliance Gap Matrix
| Compliance item | Common China baseline | Kazakhstan (EAEU TR / KEGOC / MID) | Gap / action | Source + verification date |
|---|---|---|---|---|
| 50 Hz Grid Frequency and Kazakhstan Parameter Settings | China also uses 50 Hz, so the nominal frequency is aligned. The difference is in protection bands, ride-through curves, active-power frequency response, reconnection logic, and operator-specific commissioning evidence under GB/T 19964-2024 and GB/T 37408-2019 versus Kazakhstan requirements.GB/T 19964-2024 GB/T 37408-2019 China 50 Hz grid settings |
Kazakhstan's unified power system operates on a nominal 50 Hz frequency. PV inverter firmware, protection thresholds, ride-through settings, frequency-watt behavior, reconnection timing, and commissioning records should be configured to the Kazakhstan project and the relevant network operator's technical specifications rather than left at China factory defaults.Kazakhstan unified power-system nominal frequency: 50 Hz KEGOC or local network technical specifications for project-specific protection and frequency settings Project commissioning and acceptance records |
The frequency label aligns, but grid-code settings may not. Exporters should provide Kazakhstan parameter profiles, locked settings evidence where required, commissioning screenshots or logs, and a method for verifying settings after firmware updates.[INFORMATIONAL] China and Kazakhstan both use 50 Hz, but Kazakhstan grid-connection acceptance still requires local protection and operating-parameter confirmation. | Kazakhstan Electricity Grid Operating Company (KEGOC)2026-06-14 · unverified |
| China GB/T 37408 and GB/T 19964-2024 Evidence Versus Kazakhstan Acceptance | GB/T 37408-2019 is the common China product technical requirement for PV grid-connected inverters, and GB/T 19964-2024 is the common China technical regulation for PV power stations connected to the power system. Together they are a strong China-side dossier, but they do not create EAC marking rights, Kazakhstan auction eligibility, or KEGOC grid approval.GB/T 37408-2019 GB/T 19964-2024 |
Kazakhstan import, market-access, and grid-connection decisions are based on EAEU technical regulations, Kazakhstan standards practice, and project/network approvals. Chinese GB/T reports are best treated as capability evidence to be mapped against Kazakhstan/EAEU requirements, not as automatically recognized conformity documents.EAEU TR CU 004/2011 and TR CU 020/2011 where in scope Kazakhstan ST RK / GOST / IEC-based project evidence where requested KEGOC or local network connection technical specifications |
The key gap is recognition and mapping. Exporters should prepare a clause-by-clause bridge from GB/T 37408 and GB/T 19964-2024 to TR CU 004/020, IEC 62109, project grid-code settings, and Kazakhstan-language user and installation documentation.[INFORMATIONAL] GB/T 37408 and GB/T 19964-2024 are useful starting evidence, but Kazakhstan compliance requires a separate EAEU, standards, grid, and project-approval mapping. | National Public Service Platform for Standards Information, State Administration for Market Regulation of China2026-06-14 · unverified |
| EAEU Low-Voltage Equipment Safety for PV Inverters | China commonly relies on GB/T 37408-2019 for PV grid-connected inverter technical requirements, manufacturer safety testing, and IEC 62109 reports for export projects. GB/T 37408 evidence is useful for due diligence but does not replace EAEU TR CU 004/2011 conformity assessment or EAC technical-file obligations in Kazakhstan.GB/T 37408-2019 IEC 62109-1 IEC 62109-2 |
Kazakhstan is an EAEU member state, so solar PV inverters placed on the Kazakhstan market may need EAEU conformity assessment under TR CU 004/2011 on low-voltage equipment when the product falls within the voltage and product scope. The exporter or local applicant should confirm whether the inverter is handled through declaration or certification, keep test reports and technical files, and apply EAC marking only after all applicable EAEU technical regulations are satisfied.TR CU 004/2011 — On safety of low-voltage equipment EAEU EAC marking and conformity assessment rules for products in technical-regulation scope |
A Chinese GB/T or IEC safety report does not by itself authorize sale in Kazakhstan. The gap is EAEU procedure, applicant responsibility, EAC marking, and Russian/Kazakh-language technical documentation for the declared or certified inverter model.[INFORMATIONAL] Treat TR CU 004/2011 scope and EAC documentation as a Kazakhstan market-access gate; do not rely on GB/T 37408 or IEC 62109 reports alone. | Eurasian Economic Commission2026-06-14 · unverified |
| EAEU EMC Conformity for Grid-Connected Inverters | China-side packages often include GB/T 37408-2019, GB/T 19964-2024, and EMC test evidence generated for IEC/CISPR or other export markets. Those reports may help build the EAEU technical file but must be checked against TR CU 020/2011 and the specific standards named by the Kazakhstan/EAEU conformity body.GB/T 37408-2019 GB/T 19964-2024 CISPR 11 / IEC 61000 series test evidence where available |
PV inverters with electronic power-conversion circuits and grid interfaces commonly require EAEU EMC conformity assessment under TR CU 020/2011 when supplied in Kazakhstan. The technical file should address emissions, immunity, installation conditions, cabling, filters, and operating modes relevant to grid-connected inverter use.TR CU 020/2011 — Electromagnetic compatibility of technical devices EAEU EAC marking and technical-file requirements for EMC-regulated products |
The practical gap is not only test limits. The EAEU file must match the exact model, firmware, filters, manuals, grid parameters, and intended installation. Reports prepared for China or another export market may need delta review or retesting.[INFORMATIONAL] EMC reports from China or other markets should be treated as input evidence, not as automatic TR CU 020/2011 compliance for Kazakhstan. | Eurasian Economic Commission2026-06-14 · unverified |
| ST RK / GOST / IEC 62109 Safety Evidence | Chinese manufacturers often hold IEC 62109 CB reports alongside GB/T 37408-2019 product documentation. This is usually stronger export evidence than a China-only GB/T declaration, but it still needs model-scope, factory, firmware, and national-deviation review for Kazakhstan/EAEU use.GB/T 37408-2019 IEC 62109-1 IEC 62109-2 IECEE CB Scheme reports where available |
Kazakhstan standards practice uses national ST RK standards, interstate GOST standards, and direct or adopted international standards through KazStandard and EAEU conformity routes. For PV inverters, IEC 62109-1 and IEC 62109-2 safety reports are commonly relevant technical evidence, especially when a purchaser, bank, EPC, or conformity body asks for internationally recognized inverter safety documentation.ST RK standards and Kazakhstan national standardization procedures GOST interstate standards where adopted or referenced IEC 62109-1 / IEC 62109-2 — Safety of power converters for use in photovoltaic power systems |
Kazakhstan buyers may accept IEC 62109 as persuasive technical evidence, but the acceptance path is contractual or conformity-body specific. Exporters should not assume IEC 62109 automatically resolves ST RK, GOST, TR CU, language, marking, or grid-connection requirements.[INFORMATIONAL] IEC 62109 and CB reports are useful but should be mapped into the Kazakhstan ST RK/GOST/EAEU file instead of treated as a standalone approval. | Kazakhstan Institute of Standardization and Metrology (KazStandard)2026-06-14 · unverified |
| KEGOC / Network Grid-Connection Review | China-side grid documentation usually references GB/T 19964-2024 for PV power-station grid connection and GB/T 37408-2019 for inverter technical requirements. These documents are useful for explaining inverter capability but do not substitute for Kazakhstan network studies, technical specifications, or commissioning acceptance.GB/T 19964-2024 GB/T 37408-2019 |
Utility-scale PV projects connected to Kazakhstan's national or regional electricity networks require project-specific grid-connection review, technical specifications, protection settings, power-quality evidence, dispatch or telemetry interfaces, and commissioning documentation. KEGOC is Kazakhstan's national grid operator and system-operator reference point for national-grid matters, while local networks may control distribution-level connection.KEGOC technical specifications and grid-connection procedures for Kazakhstan power-system projects Kazakhstan electricity grid code and network-operator connection requirements Project-specific dispatch, protection, metering, and telemetry requirements |
The gap is project engineering: Kazakhstan protection, voltage/reactive-power, frequency, SCADA, metering, fault-ride-through, and commissioning settings must be agreed with the relevant network operator. A China grid-code test certificate is not enough for energization.[INFORMATIONAL] GB/T 19964-2024 and GB/T 37408 help describe inverter capability, but Kazakhstan energization depends on KEGOC or local-network technical approval and commissioning evidence. | Kazakhstan Electricity Grid Operating Company (KEGOC)2026-06-14 · unverified |
| Renewable-Energy Auction and PPA Documentation | Chinese domestic PV project documents usually focus on local grid approval, GB/T 19964-2024 connection evidence, equipment type-test reports, and domestic project acceptance. These do not replace Kazakhstan auction eligibility, financial security, winner registration, or PPA execution requirements.GB/T 19964-2024 GB/T 37408-2019 China domestic project acceptance documents |
Kazakhstan uses renewable-energy auctions to select RES projects, with auction schedules approved by the Ministry of Energy and project steps involving KOREM registration, auction participation, inclusion of winners, and subsequent PPA execution through the Financial Settlement Center for Renewable Energy Sources. Inverter compliance evidence may be requested as part of EPC, financing, technical, or PPA delivery packages.Kazakhstan RES auction rules and Ministry of Energy auction schedules Financial Settlement Center for Renewable Energy Sources auction and PPA procedures KOREM auction trading-system registration procedures |
For auction-backed projects, inverter documentation must support the Kazakhstan project dossier, not only product import. Missing local tender/PPA evidence, grid studies, financial-security documents, or winner-registration steps can block the project even if the inverter has EAC or IEC test evidence.[INFORMATIONAL] For Kazakhstan auction projects, product compliance and project qualification move in parallel; EAC or IEC evidence does not replace auction, PPA, financial-security, or winner-registration documents. | Financial Settlement Center for Renewable Energy Sources LLP2026-06-14 · unverified |
