EMC Evidence — IEC 61000 Series and IEC 62920 for PV Inverters?

Do not rely on Chinese GB/T 37408-2021 or NB/T 32004 EMC evidence alone for Eswatini. Prepare IEC 62920 and relevant IEC 61000 reports for the exact inverter model, then confirm report acceptance with SWASA, ESERA, EEC, or the project owner. Record any voltage or configuration differences from Chinese domestic testing.

ESERA SSEG / Net-Metering and EEC Grid-Connection Review?

Treat ESERA approval and EEC connection review as separate local gates from any Chinese domestic grid-connection approval. Prepare IEC 62116 / IEC 61727 evidence and an Eswatini 230/400 V 50 Hz settings file, and confirm whether the project engineer or EEC requires NRS 097-2 style documentation. Chinese GB/T 19964-2024, NB/T 32004, and GB/T 37408-2021 evidence is not automatically accepted.

IEC 62109-1 / IEC 62109-2 Safety Evidence for PV Inverters?

A PV inverter supported only by Chinese GB/T 37408-2021 or NB/T 32004 safety evidence should not be treated as automatically acceptable in Eswatini. Prepare IEC 62109-1/-2 type-test evidence for the model or family and confirm acceptance with SWASA, ESERA, EEC, and the project owner before shipment or installation.

Gap matrix
Compliance item	Common China baseline	Eswatini (SWASA / ESERA / EEC)	Gap / action	Source + verification date
EMC Evidence — IEC 61000 Series and IEC 62920 for PV Inverters	Chinese PV inverter EMC evidence is commonly based on GB/T 37408-2021, NB/T 32004, and test reports from CNAS-accredited laboratories using China domestic requirements. Those reports may be useful technical support, but they are not a substitute for IEC 62920 or project-specified IEC 61000 evidence unless the test scope, limits, laboratory accreditation, model coverage, and report language are accepted by the Eswatini project reviewer, SWASA conformity process, ESERA, or EEC.GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters) NB/T 32004 — 光伏并网逆变器技术规范 (Technical Specification for Photovoltaic Grid-Connected Inverters)	PV inverter EMC evidence for Eswatini should be prepared around IEC 61000 series test methods and IEC 62920, the dedicated EMC standard for photovoltaic power conversion equipment. SWASA is the national standards authority, while ESERA and EEC may expect EMC evidence as part of SSEG, net-metering, or grid-connection documentation. Because Eswatini is integrated with Southern African power-sector practice, project specifications may also request NRS 097-2 style documentation that includes power-quality and utility-interface expectations. No automatic acceptance of Chinese domestic EMC certificates should be assumed.IEC 62920 — Photovoltaic power generating systems — EMC requirements and test methods for power conversion equipment IEC 61000 series — Electromagnetic compatibility test methods and limits SWASA standards conformity expectations ESERA SSEG / net-metering and EEC grid-connection documentation requirements	Gap: GB/T 37408-2021 or NB/T 32004 EMC evidence should be mapped clause-by-clause to IEC 62920 and the relevant IEC 61000 tests before submission. Exporters should prepare model-specific EMC reports from an internationally recognised laboratory, confirm whether the Eswatini reviewer requires ILAC-accredited reports, and document any differences between Chinese test conditions and the Eswatini 230/400 V, 50 Hz application.[INFORMATIONAL] Do not rely on Chinese GB/T 37408-2021 or NB/T 32004 EMC evidence alone for Eswatini.

ESERA SSEG / Net-Metering and EEC Grid-Connection Review	Chinese grid-connection evidence commonly includes GB/T 19964-2024 for photovoltaic power stations, NB/T 32004 for grid-connected inverter technical specifications, and domestic anti-islanding or utility-interface test reports. These documents are built for Chinese grid-operator requirements and do not automatically satisfy ESERA licensing, EEC connection review, or NRS 097-2 style Southern African interconnection expectations. Even where the nominal voltage is similar, Chinese factory firmware, relay limits, reconnection timing, and utility interface documentation should be reviewed against Eswatini project conditions.GB/T 19964-2024 — 光伏发电站接入电力系统技术规定 (Technical Requirements for Connecting Photovoltaic Power Station to Power System) NB/T 32004 — 光伏并网逆变器技术规范 (Technical Specification for Photovoltaic Grid-Connected Inverters) GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters)	Grid-tied PV inverter projects in Eswatini should be planned around three local gates: SWASA conformity expectations for standards compliance, ESERA licensing or approval for small-scale embedded generation and net-metering, and EEC connection review before energisation. Eswatini uses a 230/400 V, 50 Hz nominal low-voltage system; the 50 Hz frequency matches China, though the nominal voltage differs from China's 220/380 V. A matching frequency does not remove the need for local protection settings, anti-islanding evidence, commissioning review, and utility approval. In practice, Southern African NRS 097-2 style interconnection requirements may be used or requested, especially because Eswatini is a SADC and SACU member and imports much of its electricity from South Africa's Eskom system.ESERA small-scale embedded generation and net-metering policy framework EEC grid-connection approval and commissioning requirements IEC 62116 — Utility-interconnected photovoltaic inverters — Test procedure of islanding prevention measures IEC 61727 — Photovoltaic systems — Characteristics of the utility interface NRS 097-2 — Grid interconnection of embedded generation, likely relevant in Southern African practice	Gap: Chinese GB/T or NB/T grid-connection documents should be treated as supporting evidence only. Exporters should prepare IEC 62116 and IEC 61727 evidence, a grid-code settings sheet for Eswatini's 230/400 V 50 Hz system, anti-islanding and reconnection settings, and any NRS 097-2 style declarations requested by the local engineer or EEC. ESERA licensing or net-metering approval and EEC connection approval remain local gates that Chinese domestic approvals do not replace.[INFORMATIONAL] Treat ESERA approval and EEC connection review as separate local gates from any Chinese domestic grid-connection approval.

IEC 62109-1 / IEC 62109-2 Safety Evidence for PV Inverters	Chinese PV inverter safety evidence commonly relies on GB/T 37408-2021 and NB/T 32004, supported by domestic CQC, CGC, or CNAS-accredited laboratory reports. These documents may demonstrate a mature Chinese compliance baseline, but they are not the same as IEC 62109-1/-2 type-test evidence and should not be presented as automatically equivalent for Eswatini market entry, ESERA review, or EEC connection approval.GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters) NB/T 32004 — 光伏并网逆变器技术规范 (Technical Specification for Photovoltaic Grid-Connected Inverters)	For Eswatini PV inverter projects, safety evidence should be prepared around IEC 62109-1 and IEC 62109-2 for power converters used in photovoltaic power systems. SWASA is the national standards authority, while ESERA SSEG or net-metering review and EEC grid-connection review may require proof that the inverter model is safe for the proposed grid-tied installation. Project owners and engineers may request third-party type-test certificates covering the exact inverter family, installation environment, and firmware or hardware configuration.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 SWASA standards conformity expectations ESERA SSEG / net-metering and EEC grid-connection documentation requirements	Gap: A Chinese GB/T 37408-2021 or NB/T 32004 safety package should be supplemented with IEC 62109-1/-2 certificates or reports for the specific inverter model or family. Exporters should verify whether SWASA, ESERA, EEC, or the project owner requires ILAC-recognised laboratory evidence, English-language reports, factory inspection records, or model-family coverage details before shipment.[INFORMATIONAL] A PV inverter supported only by Chinese GB/T 37408-2021 or NB/T 32004 safety evidence should not be treated as automatically acceptable in Eswatini.
