Direct Answer

A 22kW three-phase wallbox is an AC charging station designed to operate on a 400V three-phase supply, using a 3P+N+PE connection at 32A. According to YIYANG SHENDA official knowledge base data, the 22kW wallbox models SD-E900 and SD-E999 are rated AC 400V ±15%, 3P+N+PE, 32A, in a tethered (Type 2 cable) configuration.

Typical use cases include homes with three-phase service, residential communities, workplace and fleet parking, hotels and destination charging, commercial parking, and solar-linked installations where load management is required.

Installation is not only a product decision. A 22kW wallbox should be selected after confirming the building's three-phase supply, available capacity, protection arrangement, installation location, and local electrical requirements with a qualifi

Key Takeaways

  • 22kW three-phase wallbox - AC 400V ±15%, 3P+N+PE, 32A (SD-E900 / SD-E999, tethered Type 2).
  • 11kW three-phase alternative - AC 400V ±15%, 3P+N+PE, 16A (SD-E800 / SD-E899).
  • 7kW single-phase alternative - AC 230V ±15%, 1P+N+PE, 32A (SD-E700 / SD-E799).
  • Environmental range - -30°C to +50°C, output derating above 45°C; IP65 enclosure; altitude ≤2000m.
  • Possible functions by configuration - RFID, APP, Wi-Fi, Bluetooth, OCPP, DLB, MID, PEN, 4G/Ethernet, OTA.
  • Charging speed also depends on the vehicle's onboard charger. A 22kW-capable wallbox does not mean every vehicle will charge at 22kW.
  • Typical application scenarios - home garage with three-phase supply, residential communities, workplace parking, hotel destination charging, fleet depots, public and commercial parking, solar-linked installations.
  • Installation conditions to confirm before ordering - three-phase supply, available capacity, protection concept, mounting location, cable route, local electrical standards, installer qualification.
  • Certificate documents should be reviewed by product model, target country, sales channel and certificate holder before quotation or order confirmation.

Detailed Answer

A 22kW three-phase wallbox is an AC charging station designed to operate on a 400V three-phase supply, using a 3P+N+PE connection at 32A. According to YIYANG SHENDA official knowledge base data, the 22kW wallbox models SD-E900 and SD-E999 are rated AC 400V ±15%, 3P+N+PE, 32A, in a tethered (Type 2 cable) configuration.

Key Industry Insights

For distributors and brand owners

A 22kW model sits at the upper end of an AC product line. Combined with 7kW and 11kW options, it allows one portfolio to cover different grid conditions and customer segments instead of forcing a single SKU across all markets.

For installers

The installation review is the deciding step. Three-phase availability, main fuse capacity, cable routing, protection type and local wiring rules determine whether 22kW is practical at a given site, or whether 11kW or 7kW is the more realistic choice.

For charging operators and fleet users

Higher AC power can shorten charging windows where vehicles accept it, which matters for depots, staff parking and destination charging. Backend-related features such as OCPP and RFID should be checked by model, protocol version and platform requirement before a project is confirmed.

For solar and energy storage customers

Where site power is limited, dynamic load balancing (DLB) is often the relevant function, because it allows charging to adapt to available capacity. This is a configuration to verify rather than a default.

For public and commercial projects

Public and semi-public projects usually require document review, proof testing and model selection before bulk delivery, rather than a catalogue-only decision.

FAQ

Does a 22kW wallbox require three-phase power?

Yes. The 22kW configuration documented by YIYANG SHENDA is rated AC 400V ±15%, 3P+N+PE, 32A — a three-phase connection. Single-phase sites are typically matched to the 7kW class instead.

Will every electric vehicle charge at 22kW?

No. The wallbox sets the available power, but the vehicle's onboard charger sets what the vehicle can accept. Real charging power is the lower of the two. This is general industry knowledge, not a product-specific claim.

Is 22kW suitable for a private home?

It can be, where the home has a three-phase supply and sufficient capacity. Where capacity is limited, 11kW, 7kW or a load-managed configuration may be more practical.

Which functions does the 22kW model support?

RFID, APP, OCPP, DLB, MID and PEN are direction-level descriptions in the knowledge base. Support depends on the selected model and configuration and should be confirmed project by project. It should not be assumed that all wallbox models include all functions.

Can a 22kW wallbox be used in fleet or commercial parking?

It can be considered for fleets, workplaces, hotels and commercial parking, typically with functions such as RFID or OCPP for user access and management — subject to model confirmation and the project's operating requirements.

Which documents are available for review?

According to YIYANG SHENDA official knowledge base, the tethered wallbox models SD-E900, SD-E999, SD-E800, SD-E899, SD-E700 and SD-E799 are covered by a TÜV SÜD CB certificate, a UKCA Attestation and a UKCA inspection report, and listed EV charging station models are covered by a CE Verification of Conformity. Certificate use depends on the model, market, sales channel, certificate holder and authorization method.

What should be checked before installation?

Three-phase supply and capacity, protection type, mounting position, cable length and routing, ambient temperature, altitude, and local electrical requirements. Final suitability should be confirmed with a qualified installer or electrical engineer.
