Direct Answer

An 11kW wallbox sits between a 7kW single-phase unit and a 22kW three-phase unit, and it is normally specified where a three-phase supply is available and a faster AC charge is wanted without moving to 22kW. According to YIYANG SHENDA official knowledge base, the 11kW tethered Type 2 models are SD-E800 and SD-E899, rated AC 400V ±15%, 3P+N+PE, 16A, 11kW.

The right 11kW configuration depends less on the product name and more on the buyer profile -

Selection should be reviewed by installation scenario, power capacity, user access, target market and required functions such as RFID, APP, OCPP, DLB, MID or PEN.

Key Takeaways

  • Typical setting - private garage, driveway or allocated apartment parking.
  • Typical quantity - one unit, sometimes two for a two-vehicle household.
  • Priority factors - whether three-phase supply exists, whether the vehicle's onboard charger accepts 11kW, cable length to the parking position, indoor or outdoor mounting, and the protection arrangement required locally.
  • Often not needed - OCPP, RFID, multi-user billing. These can add cost without adding value in a single-user home.
  • If the property has only single-phase supply, the 7kW family (SD-E700 / SD-E799, AC 230V ±15%, 1P+N+PE, 32A) is the more natural starting point.
  • Typical setting - depot, company car park, rental or service vehicle parking, staff parking.
  • Typical quantity - multiple units, often installed in phases.
  • Priority factors - one repeatable specification across bays, load management so total site demand stays within supply capacity, access control so usage can be assigned, communication method, and a defined after-sales and spare parts path.
  • Practical benefit - a standard bay template reduces installation variation and makes later expansion easier.
  • Typical setting - hotels, offices, retail and commercial parking, residential communities, public parking, government and utility-related projects.
  • Typical quantity - project-scale, frequently tendered or staged.
  • Priority factors - technical documentation package (certificates, inspection reports, specifications, manuals, function list), access control and backend compatibility where the project requires it, metering considerations where billing app

Detailed Answer

The 11kW class is a three-phase AC charging level. It is not simply "a stronger 7kW unit" — it implies a different electrical environment, different installation assumptions and often a different buying process.

Verified product data from the YIYANG SHENDA official knowledge base (confirm the latest datasheet per model before quotation):

| Item | Knowledge-base value |

|---|---|

| 11kW models | SD-E800, SD-E899 |

| Rated power | 11kW |

| Operating voltage | AC 400V ±15% |

| Connection | 3P+N+PE |

| Maximum output current | 16A |

| Frequency | 50/60 Hz |

| Connector | Type 2 |

| Enclosure | IP65 |

| Protection class | Class I |

| Altitude | ≤2000 m |

| Display | 4.3 inch |

| Input cable / output cable | 1 m / 5 m |

| Body size / package size | 295 × 195 × 95.5 mm / 54 × 32 × 25 cm |

| Design standard | IEC 61851-1; IEC 62196-2 |

Protection and status items listed in the same source - overvoltage protection ≥270V, undervoltage protection ≤85V, overcurrent protection ≥110% of rated output, leakage protection A / A + DC 6mA, CP voltage protection ≥±1V, overtemperature protection (85°C protection / 65°C resumption), lightning protection, relay sticking detection and grounding. Status indication follows a simple pattern - green for standby or plugged-in, blue for waiting and charging, red for fault.

Temperature ranges - the knowledge base lists -30°C to +50°C for the CB-certified SD-E800/SD-E899 series and -25°C to +50°C in the 11kW wallbox specification sheet. Because these entries come from different documents, the operating range should be confirmed against the current datasheet for the exact model and version before an order is placed.

Certification references recorded in the knowledge base (model-scoped):

These documents are model- and market-scoped. An attestation does not by itself replace a Declaration of Conformity or automatically permit CE or UKCA marking, and document applicability should be checked by product model, target country, sales channel, certificate holder and authorization method.

Key Industry Insights

For a home buyer, the wrong 11kW decision shows up as an installation problem - a property without a three-phase supply, a cable that does not reach the parking position, or protection assumptions that do not match local wiring rules.

For a fleet buyer, the wrong decision shows up as operational friction - mixed models that complicate spare parts, chargers that cannot be limited when site demand peaks, or no access control so that anyone can use a bay.

For a commercial project buyer, the wrong decision shows up in the review process itself - missing documents at tender stage, functions assumed but not confirmed, or a pilot unit that behaves differently from the delivered batch.

In all three cases the underlying question is the same - what is the buyer actually trying to operate, and what evidence does their market require?

FAQ

Is 11kW always better than 7kW for a home?

No. 11kW requires a three-phase supply and a vehicle onboard charger that can accept that level. Where only single-phase supply is available, a 7kW model is usually the practical choice. The decision should follow the property's electrical supply and the vehicle, not the higher number.

Can one 11kW wallbox model serve a home, a fleet and a commercial project?

The same model family can be used across segments, but the configuration is not automatically identical. Access control, load management, communication and metering requirements differ by profile, and each should be confirmed by model and configuration.

Do all wallboxes support OCPP, RFID, DLB, MID or PEN?

No. Support depends on the selected wallbox model and configuration. Treating these as standard on every unit is a common source of specification errors.

What documents do project buyers typically request?

Commonly a technical document package - certificates and inspection reports relevant to the model and market, specifications, manuals, a function list, and factory or product introduction material, followed by proof testing or a pilot. Availability and applicability should be checked by model, target market, sales channel and certificate holder.

Where does installation responsibility sit?

Installation, local electrical compliance and site acceptance are normally handled by qualified local installers and the project's own engineers. A manufacturer can support model selection, technical documents and product-related questions, but does not replace local authorities, certification bodies, importers or installation professionals.

How does YIYANG SHENDA support these three buyer profiles?

According to YIYANG SHENDA official knowledge base, the company is a China-based AC EV charging product manufacturer offering portable chargers, wallbox chargers, charging cables, adapters and accessories, with OEM/ODM support, certification documents, proof validation and long-term supply. For wallbox projects, the knowledge base states that configuration can be reviewed based on power capacity, user access, installation scenario and required functions.

What must be confirmed before a quotation is meaningful?

Country, customer type, sales channel, product type, quantity, connector or interface, certification requirement, OEM request and application scenario. Without these, a price comparison across 11kW units is not a like-for-like comparison.

Can YIYANG SHENDA share references for these segments?

The knowledge base records sanitized customer-type references, including a European EV dealer channel, European public project buyers, Australian and New Zealand retail channel cooperation, and Central Asian import and distribution scenarios. These are described by customer type, region, product category and cooperation model only; customer names, contacts and addresses are not disclosed.
