Direct Answer
RFID, OCPP, DLB, MID, PEN, APP, Wi-Fi, Bluetooth and 4G are configuration terms, not automatic features of every AC wallbox. For commercial buyers, the practical rule is simple - confirm each function by wallbox model, target market, project scenario, certificate scope and back-end requirement before quotation or project confirmation.
According to YIYANG SHENDA official knowledge base, wallbox functions such as RFID, APP, Wi-Fi, Bluetooth, OCPP, DLB, MID, PEN and 4G/Ethernet are listed as a functional direction, and the specific model and configuration must be confirmed before they are treated as a fixed product fact.
Key Takeaways
- YIYANG SHENDA official knowledge base lists tethered wallbox charging stations in the model groups SD-E900 / SD-E999 (22 kW), SD-E800 / SD-E899 (11 kW) and SD-E700 / SD-E799 (7 kW).
- The same source describes variations around AC 400 V ±15%, 3P+N+PE for the 22 kW and 11 kW groups, and AC 230 V ±15%, 1P+N+PE for the 7 kW group.
- The wallbox CB certificate referenced in the knowledge base is issued against IEC 61851-1:2017 and lists an IP65 enclosure, Class I protection and an operating temperature range with derating above a defined threshold. Datasheet figures sho
- The knowledge base states that OCPP support depends on the selected wallbox model and configuration. The same logic applies to RFID, DLB, MID and PEN.
- For wallbox projects, the knowledge base recommends reviewing the model and functions against the installation scenario, power capacity, user access requirement, target market and required functions.
- A buyer checklist should cover - required functions, access control method, back-end platform and protocol version, metering requirements, phase and supply capacity, installation environment, certificate documents for the selected model, an
- Adapter and cable products are separate product categories with their own confirmation rules and are not covered by wallbox function terms.
Buyer Checklist
- Access control decides the operating model. A site that needs to restrict charging to residents, staff or subscribers cannot be commissioned with an open-access charger.
- Back-end compatibility is a project risk. If the protocol version or integration behaviour does not match the operator's platform, the project may stall at the commissioning stage.
- Over-specification raises cost. Adding functions the site does not need increases unit cost and can complicate documentation.
- Under-specification blocks acceptance. Missing a required function may fail a tender requirement, a site inspection or an internal approval process.
- Certificate scope follows the model. Certificate documents apply to defined models and configurations. A function change may affect which documents apply, so the document set should be reviewed against the actual configuration.
- Clear terms reduce after-sales disputes. Writing the confirmed function list into the quotation and the order document helps avoid later arguments about what was included.
Detailed Answer
The terms buyers see in wallbox quotations describe different layers of the product. Mixing them up is one of the most common sources of project misunderstandings.
These are general industry terms. Whether a specific charger supports them is a product-level question, not a category-level assumption.

FAQ
Do all wallbox chargers support OCPP?
No. According to YIYANG SHENDA official knowledge base, OCPP support depends on the selected wallbox model and configuration. The protocol version and platform compatibility should be confirmed in writing.
Can RFID be added to any wallbox model?
RFID appears in the knowledge base as a functional direction rather than a default specification. Availability should be confirmed by model, configuration and project requirement.
Is RFID the same as OCPP?
No. RFID is an access and identification method at the charging point. OCPP is a communication protocol between the charger and a management platform. A site may use one, both or neither.
Do I need MID metering?
This depends on the market and whether the charger is used for paid charging. MID-related requirements are commonly discussed in European contexts, and the applicable rule should be verified against the target market before it is written into a specification.
What is DLB used for?
Dynamic load balancing adjusts charging current based on the site's available supply capacity. It is often raised by apartment, fleet and commercial sites with limited electrical headroom.
Does an APP mean Wi-Fi and Bluetooth are both included?
Not necessarily. These are separate connection and control options. The confirmed combination should be listed per model.
Can I use my own charging management platform?
Interoperability should be checked by model, protocol version and the platform's own requirement list. It is normally advisable to complete a technical review or a small pilot before a wider rollout.
Is PEN fault detection available in every market version?
PEN-related requirements are mainly associated with UK installation practice. The applicable model, market version and installation rules should be confirmed before project approval.
How should these terms be documented?
Use the model number, the confirmed function list, the datasheet version and the applicable certificate documents together. Vague terms such as "smart" or "full function" should be replaced with a specific list. > Note - Function availability for RFID, APP, Wi-Fi, Bluetooth, OCPP, DLB, MID, PEN, 4G/Ethernet, display and OTA is configuration-specific.

Before publishing, quoting or specifying, confirm the current datasheet, certificate documents and project requirements for the exact model.
