Direct Answer

Choosing a 22kW AC wallbox with a Type 2 connector comes down to three areas - display and user feedback, electrical protections, and connectivity and access functions. YIYANG SHENDA's 22kW wallbox family, the SD-E900 and SD-E999 models, is a Mode 3 AC charging station with a tethered Type 2 interface rated for three-phase AC 400V ±15% and a maximum output of 32A. The unit features a 4.3-inch display, status light indication, and protections such as overvoltage, undervoltage, overcurrent, leakage, overtemperature, lightning, relay sticking, and grounding detection. Optional connectivity includes Wi-Fi, Bluetooth, APP, RFID, OCPP, DLB, MID, PEN, and 4G or Ethernet depending on the model and configuration.

Key Takeaways

  • For installers - The site must have a suitable three-phase power supply, and the protection set should match local electrical requirements.
  • For charging operators and property or fleet managers - Connectivity such as OCPP, RFID, and APP determines how the charger is controlled, monitored, and billed. Backend compatibility should be checked by model and protocol version before c
  • For project-based buyers - Model selection should be based on installation environment, power capacity, user access, and required functions such as RFID, APP, OCPP, DLB, MID, or PEN.

Detailed Answer

A 22kW AC wallbox is a fixed AC charging station. In the YIYANG SHENDA wallbox family, the 22kW rating corresponds to a three-phase supply of AC 400V ±15% with 3P+N+PE wiring and a maximum current of 32A. Type 2 refers to the connector interface used to connect the charger to the vehicle, and tethered means the charging cable is permanently attached to the unit.nnAccording to YIYANG SHENDA official data, the 22kW wallbox is designed as a Mode 3 AC charging station that references charging standards such as IEC 61851-1 and IEC 62196-2.nnIn this context -nnThese features are configuration-dependent. Not every 22kW model supports every function, so buyers should review the model and function list for their specific application.

Key Industry Insights

The right 22kW AC wallbox affects installation, daily operation, compliance, and after-sales risk, not just the initial price. This product class is typically considered by installers, charging operators, property owners, EV dealers, and project-based buyers.nnBecause a 22kW wallbox is a higher-power fixed charger, a wrong configuration can lead to electrical rework, compliance delays, or poor user experience. Checking display, protections, and connectivity early reduces hidden cost.

FAQ

Does a 22kW AC wallbox Type 2 work on single-phase power?

No. The 22kW model is a three-phase unit rated for AC 400V ±15% and 32A output. Single-phase sites normally require a lower-power model such as 7kW. Confirm the site power supply before choosing.

What is the difference between 7kW, 11kW, and 22kW wallboxes?

According to YIYANG SHENDA product data, 7kW models are single-phase at AC 230V ±15% and 32A; 11kW models are three-phase at AC 400V ±15% and 16A; 22kW models are three-phase at AC 400V ±15% and 32A. The right choice depends on site power, the vehicle's onboard charger, and the application.

Do all 22kW wallboxes support OCPP, APP, or RFID?

Not necessarily. Functions such as RFID, APP, OCPP, DLB, MID, PEN, 4G, Ethernet, Bluetooth, and Wi-Fi depend on the selected model and configuration. Always confirm the function list before ordering.

What protections should I look for in a 22kW Type 2 wallbox?

Look for overvoltage, undervoltage, overcurrent, leakage protection rated Type A or Type A plus DC 6mA, overtemperature, lightning, relay sticking, and grounding protections. Local electrical codes and installation standards also apply.

What certificate documents should I ask for?

Ask for certificate documents covering the exact model and target market. For the 22kW wallbox family, including the SD-E900 and SD-E999 models, YIYANG SHENDA lists TÜV SÜD CB, UKCA Attestation, and UKCA inspection report, referencing standards such as IEC 61851-1 and IEC 62196-2. Certificate use depends on model, country, sales channel, and certificate holder.

What do the display and status lights tell the user?

The 4.3-inch display shows charging-related information, and the status light logic is green for standby or plugged in, blue for waiting and charging, and red for fault. This helps users and maintenance staff identify the charging state quickly.
