Direct Answer

An 11 kW AC wallbox is a three-phase, Mode 3 AC charging station rated for a 400 V AC supply at 16 A per phase, and it is most commonly fitted with a Type 2 connector or a Type 2 socket. YIYANG SHENDA product data lists the 11 kW wallbox models SD-E800 and SD-E899 at AC 400 V ±15%, 3P+N+PE, 16 A, 11 kW.

Two boundaries decide whether a project works in practice -

Smart functions such as OCPP, RFID, DLB, MID and PEN are configuration-dependent and must be confirmed for the exact model rather than assumed as standard.

Key Takeaways

  • Standard - IEC 62196-2, rated 32 A / 16 A, 480 V AC three-phase or 250 V AC single-phase
  • Ingress protection - IP54 unmated, IP55 mated
  • Type 2 to Type 2 cable - withstand voltage 2000 V, insulation resistance above 100 MΩ, operating temperature −30 °C to +50 °C, mechanical life above 10,000 mating cycles, insertion force ≤100 N

Buyer Checklist

  • Grid reality comes first. If the site has no three-phase supply, an 11 kW wallbox cannot deliver 11 kW. Phase availability, main fuse capacity and cable routing should be confirmed before a power class is selected.
  • Vehicle capability caps the result. Many passenger EVs have onboard chargers limited to 7 kW or 11 kW. Installing 22 kW hardware does not make a 7 kW-capable vehicle charge faster.
  • Load management may be required. Where household or building supply is constrained, dynamic load balancing or comparable load management is often specified. This is a configuration item and must be confirmed per model.
  • Total project cost includes installation, not just the unit. Three-phase supply upgrades, protective devices, cable routing, load management and installer labor can exceed the wallbox cost. Buyers should compare 7 kW and 11 kW options again
  • Certificates are model-scoped. YIYANG SHENDA data records a TÜV SÜD CB test certificate covering the Mode 3 AC charging station range, with report reference 085-253225301-000 under IEC 61851-1:2017, and a TÜV SÜD UKCA attestation covering t
  • Field issues are often installation-linked. Installation conditions, supply capacity and connector condition are frequently reported as the practical cause of AC charging problems rather than the charging unit itself. This is why installati
  • Distributor inventory should match local grid and vehicle mix. Stocking 11 kW SKUs in areas dominated by single-phase supply or 7 kW vehicles can create slow-moving inventory.
  • Documentation support scales with the project. YIYANG SHENDA supplies model-scoped datasheets, certificate references and configuration confirmation so that distributors can answer installer and end-customer questions before an order is pla

FAQ

Is an 11 kW wallbox the same as a Type 2 charging post?

No. "11 kW" describes the power class, while "Type 2" describes the connector standard under IEC 62196-2. Control pilot signalling for Mode 3 charging is covered by IEC 61851-1. A Type 2 charging post can be 7 kW, 11 kW or 22 kW depending on the model and the supply.

Can an 11 kW wallbox be installed on a single-phase supply?

Not as an 11 kW three-phase unit. The reference 11 kW specification uses a 400 V AC three-phase input. Sites without a three-phase supply are usually better served by a single-phase 7 kW model such as the SD-E700 or SD-E799 configuration.

Will every electric vehicle charge at 11 kW on this unit?

No. The vehicle onboard charger determines the accepted AC power. A vehicle limited to single-phase input or 7 kW will draw less, regardless of the wallbox rating.

Do all 11 kW models support OCPP, RFID, DLB, MID or PEN?

No. These are configuration-dependent features. Support must be confirmed for the specific model, protocol version and platform requirement before a project is committed.

Which certificates apply to the 11 kW models?

YIYANG SHENDA data records that the Mode 3 AC charging station range, including the 11 kW models, is covered by a TÜV SÜD CB test certificate and a TÜV SÜD UKCA attestation. Certificate use depends on the product model, certificate holder, customer brand, importer arrangement and target market, and attestations do not replace a Declaration of Conformity.

What is the operating temperature range for the 11 kW models?

YIYANG SHENDA 11 kW product data lists approximately −25 °C to +50 °C. Certificate documentation for the wallbox range lists −30 °C to +50 °C with derating above 45 °C. Because the applicable range depends on the exact model and document, confirm the SD-E800 or SD-E899 datasheet or certificate for the project market before quotation.

Can the unit be installed outdoors?

The reference specification lists an IP65 enclosure rating. Outdoor installation still depends on mounting position, local electrical requirements and installer assessment.

What should a distributor check before stocking this power class?

Confirm that the target market genuinely has three-phase residential or commercial supply, confirm which vehicle models are common locally, and verify which smart functions are actually required. An 11 kW SKU that does not match local grid conditions creates slow-moving inventory.

What is required before confirming an installation?

Supply capacity and phase count, protective device arrangement, cable route and length, mounting surface, user access method such as RFID or app, and local electrical standards. These are site-level decisions and cannot be resolved from a product datasheet alone. Buyer verification note - function availability for OCPP, RFID, DLB, MID and PEN, together with the applicable certificate set and the operating temperature figure, is confirmed against the exact model datasheet and certificate documents before a quotation or project commitment.
