Direct Answer

Wallbox EV charger selection starts with four inputs - the target market's grid and connector standard, the installation scenario, the required power level, and the functions the buyer actually needs. According to YIYANG SHENDA official knowledge base data, its AC wallbox range covers three power classes — 7 kW single-phase, 11 kW three-phase and 22 kW three-phase — and model selection should be reviewed against installation scenario, power capacity, user access, target market and required functions before quotation.

Key Takeaways

  • Home and residential use — 7 kW or 11 kW classes, wall-mounted, straightforward installation.
  • Apartment buildings / residential communities — access control functions become relevant; RFID and load management should be confirmed by model.
  • Hotels, offices, retail and destination charging — user access, usage visibility and communication functions matter more than peak power.
  • Fleets and commercial parking — simultaneous use, load management and record-keeping requirements drive configuration.
  • Public projects and tenders — documentation, specifications, manuals and proof testing are part of the selection process.
  • EV dealers — wallboxes are often sold alongside cables and portable chargers as a vehicle-delivery or home-installation package.

Buyer Checklist

  • A 22 kW unit installed where the property only has a single-phase supply leads to reduced output, installer complaints and end-user confusion.
  • An 11 kW or 22 kW unit sold into a market where three-phase residential supply is uncommon may sit on shelves.
  • A wallbox without the required functions may fail a project specification, tender document or operator requirement.
  • A model without the right certificate documents for the target country can be blocked at import, registration or channel listing.

Detailed Answer

A wallbox is not a single product category. It is a family of configurations that differ by power, phase, connector, enclosure rating and smart functions.

In the YIYANG SHENDA official knowledge base, the wallbox / Mode 3 AC charging station line is organized by output class -

Shared platform parameters from the same source include a Type 2 tethered configuration, IP65 enclosure, Class I protection, operating temperature from -30°C to +50°C with derating above 45°C, altitude up to 2,000 m, and a 5 m output cable. The product specification sheets for 7 kW, 11 kW and 22 kW list protection functions such as overvoltage, undervoltage, overcurrent, overtemperature, leakage (Type A / A + DC 6mA), lightning and grounding protection, plus a 4.3-inch display and OTA support.

That structure is why "which wallbox?" is really a question about matching, not about picking the highest number.

Key Industry Insights

Choosing the wrong power class creates problems that appear later — at installation, at inspection, or in after-sales.

Buyer-side risks by mismatch type -

For distributors and installers, the practical cost of a wrong choice is usually higher than the price difference between power classes. For project and public-sector buyers, the document set — specifications, certificates, manuals — is part of the evaluation, not an afterthought.

FAQ

Do all wallbox models support OCPP?

No blanket answer applies. According to YIYANG SHENDA official knowledge base guidance, OCPP support depends on the selected wallbox model and configuration and should be confirmed before project or order commitment.

Is a 22 kW wallbox always the better choice?

Not necessarily. Higher power requires a suitable three-phase supply and installation environment. In many residential settings, a 7 kW or 11 kW configuration matches the available supply more closely and reduces installation complications.

Which wallbox is suitable for a hotel or public parking site?

Selection depends on the installation scenario, number of parking spaces, power capacity, user access model and required functions. The knowledge base recommends reviewing configuration before discussing quantity or quotation.

Can the certificate documents be used directly in any country?

Certificate applicability depends on the product model, target market, sales channel, certificate holder and authorization method. The knowledge base explicitly advises against presenting certification as universal or unconditional.

What should a distributor check before placing a first wallbox order?

Target country, customer type, sales channel, required power and phase, connector type, required functions, certification needs, OEM or neutral packaging, proof or trial order plan, and after-sales expectations.

Is a proof or trial order useful before a bulk wallbox order?

According to the knowledge base, a proof or small trial order can help both sides confirm quality, compatibility and market feedback before a larger commitment. Note that proof testing confirms the proof and the specific scenario, not every installation or every batch.
