AI-compiled from official public sources — cross-checked by multiple AI models, not human-verified. Informational only; see disclaimer. Public-interest, source-linked comparison of common China solar PV inverter documentation against Switzerland CE-aligned product requirements, SNV-adopted EN/IEC standards, Swissgrid interconnection practice, anti-islanding and protection settings, and China baseline references.

Compliance Gap Matrix

Gap matrix
Compliance item Common China baseline Switzerland (SNV / ElCom / Swissgrid) Gap / action Source + verification date
Electromagnetic and Grid-Profile Evidence at 230/400 V 50 Hz Chinese inverters are often defaulted against China 50 Hz grid evidence in GB/T 37408 and GB/T 19964, but same-frequency claims do not remove the need to map Swiss 230/400 V windows and protection assumptions for the exact model and project.GB/T 37408
GB/T 19964
China domestic inverter profile documentation
Switzerland-facing inverters are typically assessed against IEC power-quality and EMC context where the 230/400 V, 50 Hz low-voltage profile is used with utility-specific settings. Even when frequency matches China, the nominal-voltage profile and project-specific harmonic, trip, and protection assumptions are part of the acceptance package.IEC 60038 system voltage classes
EN 50160 characteristics of public electricity supply
Project-specific Swissgrid and distribution-company settings
The gap is often project assumptions and evidence traceability. Exporters should provide Swiss settings tables, voltage/frequency and harmonic trip values, anti-islanding behavior, reconnection delays, documentation of EMC test scope, and commissioning evidence for each firmware version.[INFORMATIONAL] Even where frequency is matched, confirm Swiss 230/400 V settings, harmonic behavior, and project-specific protection and trip logic before energisation.

Swissgrid Interconnection and Project Acceptance China grid procedures under GB/T 19964 and GB/T 37408 can support technical preparation, but project-level Swissgrid route and operator-specific commissioning requirements must be established independently for the destination site.GB/T 19964
GB/T 37408
China State Grid / China Southern Power Grid project procedures
Switzerland-facing solar inverters for grid use require project-level interconnection coordination with Swissgrid and local network operators. Approval typically covers connection documents, single-line diagrams, metering strategy, anti-islanding settings, reactive-power behavior, and commissioning evidence before energisation.Swissgrid grid-connection process
ElCom electricity-market and network oversight framework
Project-specific distribution-operator operating instructions
The gap is the operational acceptance pack: utility project approval path, interface and relay settings, anti-islanding and LVRT/UVRT details, metering and telemetry readiness, and documented commissioning test acceptance for the selected Swiss connection point.[INFORMATIONAL] Treat Swissgrid interconnection as a separate project gate from product testing. Confirm operator-specific settings for the exact site and inverter configuration. Swissgrid2026-06-15 · reference
TS EN 62109 Safety Evidence for PV Inverter Power Converters China baseline evidence may include GB/T 37408, GB/T 19964, and related performance or grid-connection reports. These are useful for engineering comparison but do not replace Switzerland-facing EN/IEC safety evidence in CE-aligned acceptance contexts.GB/T 37408
GB/T 19964
China grid-code and design evidence
For Switzerland-facing PV inverters, TS EN 62109-1 and TS EN 62109-2 are commonly the relevant safety baseline for grid-connected power converters where SNV-adopted pathways or project requirements request it. Switzerland is not an EEA member, so conformity is handled through Swiss-adopted routes rather than direct EU-market legal status, and evidence should be mapped to the exact model and site conditions.TS EN 62109-1
TS EN 62109-2
SNV route under CE-aligned Swiss adoption where applicable
The key gap is evidence scope and traceability: target model family, power ratings, thermal assumptions, isolation design, protection philosophy, voltage and frequency settings, commissioning logs, and multilingual labels and warnings for Switzerland.[INFORMATIONAL] TS EN 62109 reporting helps close the technical gap only when mapped to Switzerland-facing project settings and commissioning scope, including 230/400 V and 50 Hz protections.
