EMC — IEC 62920 and IEC 61000-Series for PV Inverters — Georgia GEOSTM / GNERC Framework — Solar PV inverter (China → Georgia (GEOSTM / GNERC / GSE))?

Chinese GB/T 37408 EMC certificates do not satisfy Georgia GEOSTM IEC 62920 and IEC 61000-3-2 requirements. Obtain IEC 62920 and IEC 61000-3-2 type-test reports from an ILAC-accredited laboratory for the specific inverter model before GEOSTM conformity assessment or GNERC/GSE grid-connection submission.

Georgia's grid-connection requirements reference IEC 62116, IEC 61727, and IEC 61000-3-2 under its DCFTA EU/IEC alignment trajectory. Chinese GB/T grid certificates alone do not satisfy GNERC/GSE connection requirements. Prepare IEC-referenced test evidence from an ILAC-accredited laboratory and submit a GNERC/GSE grid-connection application with a full technical documentation package. Verify current applicable GNERC technical regulations and GSE/distribution operator conditions directly at gnerc.org and gse.com.ge before finalising the compliance package.

GNERC net-metering is a separate project approval gate from any Chinese domestic distributed solar approval. Confirm inverter model IEC compliance evidence (IEC 62109-1/-2, IEC 62116, IEC 61727) and distribution operator technical connection conditions with Telasi or Energo-Pro Georgia before project submission. Verify current GNERC net-metering rules and applicable technical conditions directly at gnerc.org. Georgia is not an EAEU member — do not apply the EAC/TR CU certification route.

A solar PV inverter holding only Chinese GB/T 37408 certification cannot satisfy Georgia GEOSTM IEC 62109-1/-2 conformity requirements. Plan for IEC 62109-1/-2 type testing by an ILAC-accredited laboratory before submitting equipment documentation for GEOSTM conformity assessment or GNERC/GSE grid-connection review.

Public-interest, source-linked comparison of common China solar PV inverter documentation against Georgia GEOSTM conformity requirements, GNERC grid-connection rules, GSE and distribution operator (Telasi / Energo-Pro Georgia) technical conditions, IEC 62109-1/-2 safety evidence, IEC 62116 anti-islanding, IEC 62920 / IEC 61000-series EMC, 50 Hz 220/380 V grid settings, and EU/IEC alignment trajectory under DCFTA — versus China GB/T 37408 and GB/T 19964 baselines.

Short answer

For solar PV inverters exported from China to Georgia, the key practical gaps are: (1) GEOSTM conformity assessment — Georgia adopts IEC/EN standards under its DCFTA EU-alignment trajectory; Chinese GB/T documents are not automatically accepted; (2) IEC 62109-1/-2 safety type-test evidence from an ILAC-accredited laboratory, as these are the applicable safety standards under GEOSTM/IEC alignment; (3) IEC 62116 anti-islanding compliance for GNERC-regulated grid connection; (4) IEC 62920 / IEC 61000-series EMC evidence; and (5) firmware validation against Georgia's 220/380 V, 50 Hz grid (CIS legacy parameters). Georgia is NOT an EAEU member — the EAC/TR CU certification route does not apply. The applicable route is IEC/EN conformity recognized by GEOSTM, plus GNERC and GSE/distribution operator grid-connection approval. Chinese GB/T 37408 and GB/T 19964 baselines do not satisfy Georgia's IEC-aligned conformity requirements and cannot be substituted without supplementary IEC test evidence.

EMC — IEC 62920 and IEC 61000-Series for PV Inverters — Georgia GEOSTM / GNERC Framework	Chinese PV inverter EMC is assessed under GB/T 37408-2021 (Technical Requirements for Photovoltaic Grid-Connected Inverters), which includes EMC test requirements aligned with China's domestic framework. GB/T 37408 EMC testing is conducted at CNAS-accredited Chinese laboratories. While IEC 62920 and GB/T 37408 both draw on IEC 61000-series test methods, the GB/T 37408 EMC test scope, referenced limits, and test conditions are not harmonised with IEC 62920 as adopted by GEOSTM. Chinese EMC certificates based solely on GB/T 37408 are not accepted as IEC 62920 or IEC 61000-3-2 compliance evidence for Georgia GEOSTM conformity assessment or GNERC/GSE grid-connection technical submissions.GB/T 37408-2021 — 光伏并网逆变器技术要求 (Technical Requirements for Photovoltaic Grid-Connected Inverters) — includes EMC test requirements	Georgia's standards body, GEOSTM (Georgian National Agency for Standards and Metrology), adopts IEC and EN standards as Georgian national standards under its DCFTA EU-alignment programme. The applicable EMC standards for solar PV inverters in Georgia are: (1) IEC 62920 (Photovoltaic power generating systems — EMC requirements and test methods for power conversion equipment) — the dedicated EMC standard for PV power conversion equipment; (2) IEC 61000-3-2 (Electromagnetic compatibility — Limits for harmonic current emissions for equipment with input current up to 16 A per phase); (3) IEC 61000-series conducted and radiated emission and immunity standards as applicable to the inverter power rating and installation environment. No standalone GEOSTM-specific EMC Technical Regulation exclusively for solar inverters has been identified as of the last verification date; EMC requirements for Georgia PV inverters are expected to be embedded in applicable IEC/EN product standards adopted by GEOSTM and in GNERC/GSE grid-connection technical conditions. Georgia's DCFTA alignment is ongoing — EMC regulatory requirements may tighten as EU technical regulations are progressively adopted.IEC 62920 — Photovoltaic power generating systems — EMC requirements and test methods for power conversion equipment (adopted by GEOSTM under IEC/EN alignment) IEC 61000-3-2 — Electromagnetic compatibility — Limits for harmonic current emissions (equipment with input current up to 16 A per phase) IEC 61000-series — Electromagnetic compatibility standards (conducted/radiated emissions and immunity) as applicable to inverter power class and installation GEOSTM (Georgian National Agency for Standards and Metrology) — IEC/EN standards adoption under DCFTA	Chinese GB/T 37408 EMC testing does not satisfy Georgia GEOSTM IEC 62920 and IEC 61000-3-2 requirements.

Georgia and China share the same nominal grid voltage (220/380 V at 50 Hz), so voltage-related retesting may not be required — however, confirm with the GNERC/GSE technical reviewer or GEOSTM conformity assessment body whether test conditions used are acceptable.

GNERC / GSE Grid-Connection Requirements — Anti-Islanding (IEC 62116), IEC 61727, and 50 Hz / 220 V / 380 V Settings	Chinese grid-connection evidence commonly includes GB/T 19964-2024 (Technical Requirements for Connecting Photovoltaic Power Station to Power System, applicable to utility-scale PV via 10 kV and above), NB/T 32004 (inverter technical specifications), GB/T 37408-2021 (Technical Requirements for Photovoltaic Grid-Connected Inverters), and domestic anti-islanding test results. While Georgia and China share the same nominal grid voltage (220/380 V at 50 Hz), Chinese grid-connection documents based on Chinese grid standards are not automatically accepted by GNERC, GSE, or Georgian distribution operators as grid-connection evidence.

Distribution is operated by Telasi (Tbilisi) and Energo-Pro Georgia (regions). Georgia's grid operates at 50 Hz, single-phase 220 V, three-phase 380 V — a CIS-legacy parameter set shared with China. Under Georgia's Deep and Comprehensive Free Trade Area (DCFTA) agreement with the EU, Georgia is progressively aligning technical regulations with EU/IEC standards. Key grid-connection requirements for PV inverters include: (1) IEC 62116 anti-islanding test evidence — inverters must detect loss of mains and disconnect within the required window; (2) IEC 61727 (Photovoltaic systems — Characteristics of the utility interface) compliance for grid-interface parameters; (3) IEC 61000-3-2 harmonic current emission limits; (4) firmware and protection relay settings validated against Georgia's 220/380 V, 50 Hz grid parameters.
