BSTI Scope Check for Solar PV Inverters China factory files may include GB/T inverter reports, CQC or CGC voluntary certificates, IEC CB reports, Chinese labels, and domestic shipping papers. These are useful inputs but do not determine Bangladesh BSTI mandatory scope or import clearance status.GB/T 37408
GB/T 19964
NB/T 32004
IEC 62109 CB Scheme reports where held		 BSTI is Bangladesh's national standards and conformity-assessment body. Bangladesh moved to make solar inverter imports subject to BSTI mandatory certification in 2021 via Statutory Regulatory Order (SRO), incorporating IEC 62109-1 and IEC 62109-2 as the applicable safety standards. Confirm the current import-policy order status and whether the exact inverter HS code and model are in scope, as implementation timelines and lab capacity have evolved since the 2021 announcement.Bangladesh Standards and Testing Institution Act, 2018

IEC 62109 Safety Evidence for PV Power Converters China-origin inverter packages may contain IEC 62109 CB certificates and GB/T 37408 or NB/T 32004 reports. The Bangladesh file should map the exact model, critical components, software version, residual-current protection, labels, warnings, and manuals rather than relying on a generic China certificate title.GB/T 37408
NB/T 32004
IEC 62109-1
IEC 62109-2		 IEC 62109-1 and IEC 62109-2 are the international safety baseline for power converters used in photovoltaic power systems and for inverter-specific requirements. In Bangladesh, IEC 62109 evidence may be requested by BSTI, SREDA project reviewers, utilities, EPC contractors, tenders, financiers, insurers, or buyers even where a public source does not prove a blanket mandatory whole-unit certificate for every PV inverter.IEC 62109-1
IEC 62109-2
IECEE CB Scheme where accepted by the Bangladesh stakeholder		 Build one identity and safety crosswalk linking factory model codes, sales SKUs, labels, CB certificates, test reports, critical component lists, manuals, packing list, invoice names, and Bangladesh project or import names.[INFORMATIONAL] IEC 62109 is the core safety-evidence package when requested, but it is not by itself a Bangladesh grid approval, import clearance, or BSTI scope decision.

China GB/T 37408 / GB/T 19964 Baseline Versus Bangladesh Acceptance The common China baseline includes GB/T 37408-2019 for photovoltaic inverter technical requirements, GB/T 19964-2024 (effective March 15, 2024, superseding GB/T 19964-2012) for photovoltaic power-station grid connection, NB/T 32004-2018 for PV grid-connected inverter requirements, and voluntary CQC or CGC certification where held. Ensure any China technical file references the current 2024 edition rather than the superseded 2012 edition.GB/T 37408-2019
GB/T 19964-2024 (supersedes GB/T 19964-2012; effective March 15, 2024 — technical requirements for connecting photovoltaic power stations to the power system)
NB/T 32004-2018
CQC / CGC voluntary certification rules where applicable		 Bangladesh acceptance is controlled by the relevant BSTI scope decision, SREDA net-metering route, BPDB / DPDC or other utility approval, customs route, buyer requirements, and project documents. China GB/T reports are useful technical baselines, but they are not Bangladesh standards unless accepted by the Bangladesh route for the exact shipment or project.BSTI scope decision for the exact product route
SREDA net-metering and renewable-energy project route where applicable
BPDB / DPDC / distribution utility site-specific grid requirements		 Create a standards crosswalk from each Chinese clause and test report to IEC 62109 safety evidence, Bangladesh utility protection settings, labels, manuals, importer declarations, and the exact buyer or project specification.[INFORMATIONAL] Use China GB/T files as source evidence for a Bangladesh crosswalk; do not present them as automatic BSTI, SREDA, BPDB, DPDC, or customs acceptance.

Document Set for Bangladesh Review A China export file may already include IEC CB certificates, GB/T reports, factory ISO certificates, labels, manuals, and utility-setting screenshots. These should be normalized into a Bangladesh file with consistent model names and local project references.GB/T 37408
GB/T 19964
NB/T 32004
IEC 62109 CB Scheme reports		 A Bangladesh-ready file should combine product identity, IEC 62109 safety evidence where requested, BSTI scope memo, SREDA or utility application materials, 50 Hz setting sheet, English manuals and labels, importer details, and project-specific declarations. The exact required set depends on whether the shipment is for retail sale, EPC procurement, rooftop net metering, utility-scale generation, or replacement equipment.BSTI product and standards scope where applicable
SREDA Net Metering Guideline 2018 where applicable
BPDB / DPDC / distribution utility project requirements where applicable
IEC 62109-1 / IEC 62109-2 where requested		 Resolve naming mismatches across factory model, export invoice, label, CB certificate, GB/T report, SREDA form, utility application, and project bill of materials before relying on any certificate.[INFORMATIONAL] The deliverable for Bangladesh should be a route-specific file, not a generic bundle of China certificates.

Bangladesh 50 Hz Grid Frequency and Protection Settings China also uses a 50 Hz grid, so base hardware is often compatible. The gap is not nominal frequency alone; it is the local firmware profile, trip thresholds, reconnection delay, anti-islanding behavior, and utility commissioning proof required in Bangladesh.GB/T 19964
NB/T 32004
China 50 Hz utility profiles		 Bangladesh operates a 50 Hz power system. PV inverters should be configured and documented for the Bangladesh utility's nominal frequency, frequency trip limits, reconnection timing, voltage and frequency ride-through or disconnection expectations, and commissioning evidence required for the specific project.Bangladesh 50 Hz utility supply practice
SREDA Net Metering Guideline 2018 (originally capped installation at 70% of sanctioned load; subsequent updates raised this to 100% — confirm the current applicable guideline version for the project)
Project-specific BPDB / DPDC / distribution utility frequency-protection settings
SREDA net-metering application settings where applicable		 Keep a Bangladesh settings sheet showing nominal frequency, frequency and voltage trip points, reconnection delay, active/reactive power functions, anti-islanding method, firmware version, password or installer-lock control, and final commissioning screenshots or logs.[INFORMATIONAL] Shared 50 Hz nominal frequency reduces hardware risk, but Bangladesh project files still need local protection settings and commissioning evidence.

SREDA Net Metering Guideline 2018 for Customer-Side Solar China domestic distributed-PV interconnection files, State Grid or China Southern Power Grid records, and GB/T reports can support engineering review, but they do not create SREDA net-metering eligibility or utility acceptance in Bangladesh.GB/T 19964
GB/T 37408
NB/T 32004		 Bangladesh's SREDA net-metering framework is the practical route for many rooftop and customer-side solar projects that export surplus electricity to the distribution network. The inverter package should support the net-metering application with model identity, single-line diagrams, anti-islanding behavior, protection settings, metering interface information, commissioning records, and any utility-required declarations.SREDA Net Metering Guideline 2018
SREDA renewable-energy project documentation expectations
Distribution utility net-metering application requirements		 The gap is project and utility acceptance, not only product testing. Prepare Bangladesh-specific diagrams, inverter setting tables, export-limiting evidence where used, meter compatibility notes, owner declarations, and commissioning sign-off for the distribution utility file.[INFORMATIONAL] SREDA inverter enlistment is a mandatory prerequisite for net-metering project approval in Bangladesh; check the SREDA approved-inverter list before committing a model. A China grid certificate does not by itself prove Bangladesh net-metering readiness. Sustainable and Renewable Energy Development Authority (SREDA), Bangladesh2026-06-14 · unverified
BPDB / DPDC Distribution Grid Acceptance China utility acceptance records and GB/T 19964 or NB/T 32004 test results are technical inputs only. Bangladesh utilities may require their own application forms, protection settings, inspections, witness tests, and metering acceptance.GB/T 19964
NB/T 32004
Chinese utility interconnection records		 Grid-connected PV inverter projects in Bangladesh must satisfy the relevant utility's interconnection, protection, metering, commissioning, and operating requirements. Depending on the service area, the reviewer may be BPDB, DPDC, DESCO, BREB, or another distribution utility; BPDB / DPDC references should be treated as utility-route examples, not as universal approval for all sites.BPDB project-specific grid-connection and commissioning requirements
DPDC distribution interconnection and metering requirements where the site is in DPDC territory
Bangladesh utility protection and anti-islanding settings for connected distributed generation		 Map each inverter protection function to the Bangladesh utility file: over/under-voltage, over/under-frequency, anti-islanding, reconnection delay, power factor or reactive-power functions, remote disconnection if required, and commissioning evidence.[INFORMATIONAL] Treat BPDB / DPDC or other utility acceptance as a site-specific grid gate separate from factory IEC or China GB/T reports.
