Compliance item Common China baseline Thailand (TISI / MEA / PEA) Gap / action Source + verification date
Thailand 50 Hz Grid Settings and EMC Evidence China GB/T 37408 and grid-test reports may include frequency, harmonic, and protection behavior. They should be checked for Thai 50 Hz settings, firmware country profile, and EMC report applicability rather than reused without a project-specific settings review.GB/T 37408
GB/T 19964
IEC 62920:2017		 Thailand distribution-network projects normally require inverter settings suitable for the local 50 Hz network and the relevant utility protection scheme. EMC evidence should cover conducted and radiated disturbance, immunity, harmonic behavior, and installation controls relevant to a grid-connected power converter, especially when the same hardware is sold across 50 Hz and 60 Hz markets.MEA or PEA project-specific 50 Hz grid settings
IEC 62920:2017
IEC 61000 series EMC test methods as applicable		 Prepare a Thailand settings sheet showing nominal frequency, trip and reconnection thresholds, voltage windows, ramp-rate and power-quality functions, plus EMC reports tied to the exact enclosure, filter, cable, and firmware configuration shipped.[INFORMATIONAL] Revalidate the inverter's Thailand 50 Hz profile and EMC evidence against the actual shipped configuration and the utility project file.

China GB/T 37408 / GB/T 19964 Baseline Versus Thai Acceptance The common China baseline is GB/T 37408 for photovoltaic grid-connected inverter technical requirements and GB/T 19964 for photovoltaic power-station grid connection. Exporters should keep the bare standard numbers when editions are not confirmed in the specific certificate or test report.GB/T 37408
GB/T 19964		 Thai acceptance is controlled by the relevant TISI scope decision, MEA or PEA grid-connection process, ERC project or licence conditions, and customer procurement requirements. China GB/T 37408 and GB/T 19964 are useful technical baselines for Chinese PV inverter performance and PV power-station grid-connection behavior, but they are not Thai standards and do not create automatic market access in Thailand.TISI product-scope review
MEA / PEA grid-connection approval
ERC project or licence conditions		 Convert the China baseline into a Thailand-ready matrix: list each test item, report number, model covered, firmware profile, grid-code parameter, deviation, and Thai reviewer action needed. Use bare GB standard numbers until the exact edition is confirmed from the certificate or official standards database.[INFORMATIONAL] Use GB/T 37408 and GB/T 19964 as a China baseline only; Thai reviewers still need local scope, grid, project, and procurement evidence.

MEA / PEA Grid-Connection Code and Project Approval China GB/T 19964 and GB/T 37408 evidence can describe Chinese grid behavior and inverter technical performance, but it does not replace Thai utility review, local drawings, metering arrangements, or site commissioning under MEA or PEA procedures.GB/T 19964
GB/T 37408		 Solar PV projects in Thailand must be reviewed against the requirements of the distribution utility serving the site. PEA publishes grid-connection requirements, including the B.E. 2559 requirements and PEA's 2022 revision notice on connection format and protection, use-of-network requirements, operation requirements, and change-of-equipment notices for connected generators; MEA territory projects should be handled through MEA's corresponding connection and approval process. Inverter settings, protection functions, anti-islanding behavior, metering, drawings, and commissioning documents are project approval items, not only factory product-test items.PEA grid-connection requirements B.E. 2559
PEA 2022 revision notice on connection format and protection under PEA grid-connection requirements B.E. 2559 (converter_revise2022.pdf; B.E. 2565 update)
PEA use-of-network requirements B.E. 2559
PEA network operation requirements B.E. 2559
MEA project-specific grid-connection approval		 The exporter should provide Thai project teams with adjustable grid-code parameter tables, anti-islanding evidence, protection relay logic, single-line diagrams, meter and CT/PT details where relevant, firmware-locking or installer-setting instructions, and model certificates aligned to the equipment installed on the site.[INFORMATIONAL] Treat MEA / PEA interconnection as a local project gate; China GB/T reports are supporting evidence, not Thai utility approval.

ERC Rooftop PV Regulation and Inverter-Capacity Changes China factory certificates, GB/T 37408 type-test documents, and GB/T 19964 grid-connection evidence do not determine Thai ERC licence status, approved AC capacity, PPA terms, or whether an inverter substitution is acceptable after approval.GB/T 37408
GB/T 19964		 Thailand's Energy Regulatory Commission regulates electricity industry licensing and related notices. ERC has published notices concerning changes to installed solar-panel capacity and inverter capacity for licensed solar electricity producers selling electricity into utility networks. For rooftop or distributed PV projects, inverter model, AC capacity, export behavior, and later equipment changes may need to match the approved project, licence, PPA, or utility file.Energy Industry Act B.E. 2550
ERC notices for solar electricity producers and inverter-capacity changes
Project licence, PPA, and utility approval conditions		 The gap is administrative traceability. Exporters should provide exact model, serial-number range, AC and DC ratings, firmware version, derating options, datasheets, and substitution-impact notes so the Thai developer can maintain the project approval file when equipment is changed.[INFORMATIONAL] Keep inverter capacity and model data aligned with the Thai ERC, PPA, and utility file; do not treat a China model-family certificate as approval for a Thai project change.

TISI / TIS Product-Standard Check and IEC 62109 Safety Evidence China dossiers often include GB/T 37408, NB/T 32004, IEC 62109 test reports, CQC or CGC certificates, and factory model-family data. These can support technical review but do not by themselves prove that the product is outside or inside a Thai TISI / TIS route.GB/T 37408
NB/T 32004
IEC 62109-1:2010
IEC 62109-2:2011		 Thailand market access should start with a TISI scope check for the exact inverter model and use case. Publicly available TISI materials do not support a blanket statement that every complete solar PV inverter is subject to a compulsory whole-unit TIS licence, so the conservative position is to verify the applicable Thai Industrial Standard route and prepare IEC 62109-1:2010 / IEC 62109-2:2011 safety evidence for buyer, utility, project-owner, or regulator review where requested.Thai Industrial Standards Institute product-scope and TIS licence review
IEC 62109-1:2010
IEC 62109-2:2011		 The gap is scope certainty and local acceptance, not just test coverage. Exporters should map model ratings, topology, isolation, firmware, labels, manuals, and report holder names to the Thai importer and project file before assuming an IEC 62109 report will be accepted.[INFORMATIONAL] Start with a TISI scope check and keep IEC 62109 evidence ready, but do not describe IEC 62109 or a China certificate as automatic Thai product approval.
