GAP MATRIX
Compliance Gap Matrix
| Compliance item | Common China baseline | Zimbabwe (SAZ / ZERA / ZESA) | Gap / action | Source + verification date |
|---|---|---|---|---|
| EMC and Power Quality — IEC 62920 / IEC 61000 Evidence for Zimbabwe PV Inverters | China EMC files may include GB/T 37408-2021 EMC clauses, GB 17625 series harmonic limits, GB/T 17626 series immunity tests, GB/T or GB adoptions of IEC/CISPR methods, CNAS reports, and CQC/CGC certificate annexes. These reports can support technical comparison but should be checked against the exact IEC 62920 / IEC 61000 edition, laboratory acceptability, and Zimbabwe project route.GB/T 37408-2021 — 光伏并网逆变器技术要求 GB 17625 series — harmonic-current and voltage-fluctuation limits GB/T 17626 series — EMC immunity tests |
PV inverters are switching power-electronic equipment, so Zimbabwe project files should include EMC and power-quality evidence mapped to IEC 62920 and applicable IEC 61000 series tests, including conducted and radiated emissions, immunity, harmonic current emissions, flicker where applicable, and installation assumptions such as cable lengths, filters, earthing, surge protection, and battery coupling. The applicable evidence should be aligned with SAZ-recognised standards evidence, ZERA grid/distribution-code expectations, ZETDC connection conditions, and project-owner requirements.IEC 62920 — Photovoltaic power generating systems — EMC requirements and test methods for power conversion equipment IEC 61000 series — electromagnetic compatibility, harmonics, flicker, immunity, and power-quality tests where applicable SAZ standards evidence and ZERA Grid Code / Distribution Code requirements where applicable |
Gap: China EMC reports do not automatically demonstrate IEC 62920 / IEC 61000 acceptance for Zimbabwe. Exporters should map emissions, harmonics, flicker, immunity, surge, earthing, filter configuration, cable assumptions, and battery-coupled operating modes to the exact inverter configuration submitted to SAZ, ZERA, ZETDC, the project owner, insurer, or lender.[INFORMATIONAL] Use China EMC reports only as supporting evidence. For Zimbabwe, map the inverter's EMC and power-quality file to IEC 62920 / IEC 61000, the actual 230/400 V 50 Hz installation, and any SAZ, ZERA, ZETDC, project-owner, insurer, or lender requirements. | International Electrotechnical Commission (IEC)2026-06-14 · unverified |
| Zimbabwe Grid-Connection Standards — IEC 62116, IEC 61727, and 230/400 V 50 Hz Settings | Chinese grid-connection evidence commonly includes GB/T 19964-2024 for PV power-station grid connection, NB/T 32004 inverter technical requirements, GB/T 37408-2021 inverter requirements, and domestic anti-islanding and grid-support tests. These are designed around Chinese grid rules and voltage profiles and should not be submitted as a substitute for Zimbabwe IEC evidence or ZETDC-approved settings.GB/T 19964-2024 — 光伏发电站接入电力系统技术规定 GB/T 37408-2021 — 光伏并网逆变器技术要求 NB/T 32004 — 光伏并网逆变器技术规范 |
Zimbabwe grid-tied PV projects should prepare inverter grid-interface evidence around IEC 62116 anti-islanding, IEC 61727 utility-interface requirements, IEC 61000 power-quality evidence, and project-specific ZETDC connection conditions. Zimbabwe's low-voltage supply is commonly treated as 230/400 V at 50 Hz, so inverter firmware profiles, voltage and frequency trip windows, reconnection timing, active/reactive power functions, export limitation, and commissioning records should be validated for the Zimbabwe site rather than only for China 220/380 V factory settings.IEC 62116 — Utility-interconnected photovoltaic inverters — Test procedure of islanding prevention measures IEC 61727 — Photovoltaic systems — Characteristics of the utility interface IEC 61000 series — electromagnetic compatibility and power-quality requirements, where applicable ZERA Electricity Grid Code and Electricity Distribution Code regulations ZETDC project-specific distribution-network connection and commissioning conditions |
Gap: China grid certificates do not prove IEC 62116 / IEC 61727 conformity, Zimbabwe 230/400 V settings, or ZETDC acceptance. Exporters should provide model-specific IEC anti-islanding and utility-interface evidence, firmware setting tables, locked parameter files, commissioning screenshots, and any protection studies requested by ZETDC or the project engineer.[INFORMATIONAL] Treat IEC 62116, IEC 61727, Zimbabwe 230/400 V 50 Hz firmware settings, and ZETDC connection conditions as separate gates from China GB/T 19964-2024, GB/T 37408-2021, or NB/T 32004 evidence. | Zimbabwe Energy Regulatory Authority (ZERA)2026-06-14 · unverified |
| ZERA Licensing and Net-Metering — Rooftop, C&I, and Captive Solar Projects | China distributed-PV connection approvals and grid-company acceptance records are based on Chinese NEA policy, State Grid or China Southern Power Grid procedures, GB/T 19964-2024, GB/T 37408-2021, and NB/T 32004. Those approvals do not create a Zimbabwe generation licence, net-metering eligibility, or ZETDC connection right.GB/T 19964-2024 — 光伏发电站接入电力系统技术规定 GB/T 37408-2021 — 光伏并网逆变器技术要求 NB/T 32004 — 光伏并网逆变器技术规范 Chinese grid-company distributed-PV acceptance records |
Zimbabwe's prolonged load-shedding has driven strong rooftop, commercial and industrial, mining, and battery-backed solar uptake. ZERA is the energy-sector regulator and publishes electricity application forms, regulations, grid-code and distribution-code documents, generation licence materials, and net-metering-related regulatory materials. Projects that export power, sell electricity, participate in net metering, or exceed applicable licence thresholds should treat ZERA licensing or registration and ZETDC metering/connection review as project gates, separate from inverter type testing.ZERA Energy Regulatory Authority Act and Electricity Act mandate ZERA electricity application forms and generation licence application materials ZERA Electricity Grid Code and Electricity Distribution Code regulations ZERA net-metering regulations and ZETDC metering / connection review where applicable |
Gap: project approval is not the same as product compliance. For Zimbabwe rooftop, C&I, mining, and captive solar projects, confirm whether the plant size, export arrangement, sale of electricity, battery configuration, or net-metering application triggers ZERA licensing or registration and ZETDC interconnection conditions before committing equipment.[INFORMATIONAL] ZERA licensing or net-metering and ZETDC connection review are project gates, not inverter certificates. Confirm current ZERA thresholds, forms, and ZETDC metering or export-limitation requirements before shipping equipment for rooftop, C&I, mining, or captive solar projects. | Zimbabwe Energy Regulatory Authority (ZERA)2026-06-14 · unverified |
| IEC 62109-1 / IEC 62109-2 Safety Evidence — SAZ Conformity and Zimbabwe Project Files | China-side PV inverter safety and performance files commonly reference GB/T 37408-2021, NB/T 32004, voluntary CQC or CGC certificates, CB reports, CNAS laboratory reports, and factory quality records. These documents can help build the Zimbabwe technical file, but a China GB/T certificate alone should not be treated as SAZ conformity, IEC 62109-1/-2 type-test coverage, ZERA licensing evidence, or ZETDC connection approval.GB/T 37408-2021 — 光伏并网逆变器技术要求 NB/T 32004 — 光伏并网逆变器技术规范 CQC / CGC voluntary PV inverter certification and CB reports, where available |
Zimbabwe solar PV inverter projects should treat IEC 62109-1 and IEC 62109-2 type-test evidence as the core electrical-safety file for power converters. SAZ develops and publishes Zimbabwean standards and provides standards, certification, and conformity services; Zimbabwe projects may require SAZ-recognised standards evidence, product certification, or consignment-based conformity assessment depending on the import and procurement route. Safety evidence should cover the exact inverter model or family, ratings, firmware-relevant configuration, labels, installation manual, environmental assumptions, and any battery-coupled operating mode.IEC 62109-1 — Safety of power converters for use in photovoltaic power systems — Part 1: General requirements IEC 62109-2 — Safety of power converters for use in photovoltaic power systems — Part 2: Particular requirements for inverters SAZ standards, certification, product certification, and conformity assessment services where applicable to the import or project route |
The gap is safety-standard mapping and local conformity acceptance. Prepare IEC 62109-1/-2 certificates and reports for the exact inverter model, then map labels, manuals, environmental limits, protective functions, and battery interfaces to the Zimbabwe project file. Confirm with SAZ, the importer, and the project owner whether SAZ certification or consignment-based conformity assessment is required before shipment.[INFORMATIONAL] Do not rely on China GB/T 37408-2021 or NB/T 32004 safety files as automatic Zimbabwe acceptance. Build a Zimbabwe technical file around IEC 62109-1/-2 evidence and confirm the SAZ conformity route before shipment. | Standards Association of Zimbabwe (SAZ)2026-06-14 · unverified |
