Direct Answer
A wallbox charger becomes an "installation package" when the hardware is combined with the site review, model selection, protection functions, accessories, documentation and after-sales support that a specific site needs. For installers, that means offering a defined, reviewable charging solution instead of a single box. According to YIYANG SHENDA official knowledge base, wallbox model selection should be based on installation environment, power supply, protection requirements and local electrical standards, and the suitable configuration is reviewed before quantity or quotation is discussed.
Key Takeaways
- Power level follows the site, not the catalogue. Single-phase and three-phase availability, incoming capacity and the vehicle's onboard charger all shape what a 7kW, 11kW or 22kW unit can realistically deliver.
- Protection functions are part of the package. The knowledge base lists overvoltage, undervoltage, overcurrent, over-temperature, lightning, grounding and leakage protection directions for the wallbox range. Leakage protection is described a
- Smart functions must be confirmed by model and configuration. RFID, APP, Wi-Fi, Bluetooth, OCPP, DLB, MID, PEN, 4G or Ethernet, and a display are described as function directions. They are not automatically present on every unit, and OCPP,
- Certificates are model-specific. The knowledge base records TÜV SÜD CB and UKCA-related documents for the Mode 3 AC charging station range. Applicability still depends on product model, target country, sales channel, certificate holder and
- Documentation supports the installation. Specification sheets, manuals and available certificate documents help installers, project reviewers and end customers confirm the configuration.
- Accessories complete the job. Brackets, cable holders and related items can support installation, display and after-sales replacement when matched to the correct main product.
- After-sales is part of the offer. A defined route for feedback, diagnostics and spare parts keeps the package usable after commissioning.
Buyer Checklist
- Homeowners want a safe, straightforward installation with clear user access.
- Apartment and residential projects often need shared access or usage control.
- Hotels, offices and retail sites tend to focus on usable capacity and reliable service.
- Fleets and commercial sites need repeatable deployment across multiple parking positions.
- Public or project buyers usually ask for specification, manual and available certificate documents before delivery.
Detailed Answer
An AC wallbox is only one part of what a customer is actually buying. Installers add value by turning the product into a repeatable package that covers the site, the electrical conditions and the owner's use case.
A practical installation package usually includes -
Based on YIYANG SHENDA official knowledge base, the wallbox range covers three common power levels -
| Power | Example model direction | Typical electrical basis |
|---|---|---|
| 7kW | SD-E700 / SD-E799 | AC 230V ±15%, 1P+N+PE, 32A |
| 11kW | SD-E800 / SD-E899 | AC 400V ±15%, 3P+N+PE, 16A |
| 22kW | SD-E900 / SD-E999 | AC 400V ±15%, 3P+N+PE, 32A |
The same knowledge base describes IP65 enclosure, Class I protection class, an operating range of -30°C to +50°C with derating above 45°C, and an altitude limit of ≤2000m for these units. These figures describe specific models and should be confirmed against the latest datasheet before installation planning.
Key Industry Insights
Different buyers care about different parts of the package, so installers rarely sell the same offer twice.
For installers, packaging the offer this way makes it easier to explain what is included, what has to be checked on site, and what happens after installation. It also reduces the risk of buying the wrong configuration and dealing with avoidable call-backs.
YIYANG SHENDA official knowledge base notes that for wallbox projects the supplier can help review product configuration based on power capacity, user access, installation scenario and required functions, and can support technical document review, proof testing and model selection before bulk delivery.
FAQ
Does every wallbox support OCPP, DLB, MID or PEN?
No. Support depends on the selected model and configuration. These should be confirmed case by case before a project is quoted or confirmed.
Can I choose a wallbox based on price alone?
The knowledge base recommends reviewing model selection against installation environment, power supply, protection requirements and local electrical standards. Price alone does not show whether the unit fits the site.
Are the certificates valid in every country?
Certification documents should be reviewed by product model, target country, sales channel, certificate holder and authorization method. Availability of a document does not automatically mean it applies everywhere.
What should I confirm before proposing an installation package?
Country, customer type, sales channel, product type, quantity, plug or interface, power and current needs, certification requirements and any OEM request. This is the same pre-quotation checklist described in the knowledge base.
Can a portable charger replace a wallbox in a package?
Portable chargers and wallbox chargers serve different needs. Portable units are often used for backup, travel or delivery scenarios, while wallboxes are typically chosen for fixed home or commercial installation. Some packages combine both.
Who is responsible for the installation itself?
Installation should be carried out according to local electrical standards and by appropriately qualified personnel. The knowledge base states that wallbox model selection should follow the installation environment, power supply and local electrical standards.
