Direct Answer

A 7kW wallbox is a single-phase AC charging station, typically rated at 230V and 32A, using a Type 2 connector. It is the standard home and light-commercial charging class in markets where the mains supply is single-phase, and it matches electric vehicles whose onboard charger accepts roughly 6.6–7.4kW.

According to YIYANG SHENDA official knowledge base, the 7kW wallbox models SD-E700 and SD-E799 are rated AC 230V ±15%, 1P+N+PE, 32A, 7kW, with an IP65 enclosure, Class I protection and a residential use profile.

Before ordering, confirm three things - the model, the certificate documents that apply to your target market and sales channel, and whether the site has the single-phase capacity and protection arrangement the installation requires.

Key Takeaways

  • 7kW is a power class, not a product feature. It describes how much AC power the unit can deliver to the vehicle under standard single-phase conditions.
  • Single-phase vs three-phase is the first decision. 7kW units are built for 1P+N+PE supply. 11kW and 22kW units in the same family are built for 3P+N+PE supply.
  • The vehicle onboard charger sets the ceiling. If a vehicle's onboard charger accepts about 6.6–7.4kW, a 7kW wallbox can match it. A vehicle with an 11kW three-phase onboard charger will normally charge at around 7kW on a single-phase connec
  • "Wallbox" and "AC charging station" describe the same product category. In technical documents, this is often written as a Mode 3 AC charging station.
  • Power - 7kW
  • Connector - Type 2
  • Operating voltage - 230Vac ±15%
  • Output current (max): 32A

Key Industry Insights

For distributors and e-commerce sellers, the 7kW class is usually the highest-volume home charging SKU, which makes specification errors expensive - a wrong power class can mean returns, installation call-backs and platform complaints.

For installers, the 7kW class determines whether the site needs single-phase or three-phase preparation, which affects cable runs, protection devices and labour time.

For EV dealers and fleet or property projects, choosing 7kW versus 11kW affects how fast a car is ready to drive again, and whether an existing building supply can support a bank of chargers without an upgrade.

For all of these buyer types, the practical question is the same - does the model match the grid, the vehicle and the local electrical requirements at the same time?

FAQ

Is a 7kW wallbox single-phase?

Yes. In this product family the 7kW version is specified as 1P+N+PE, AC 230V ±15%, 32A. The 11kW and 22kW versions are specified for three-phase 400V supply.

Will a 7kW wallbox charge every electric car?

It can charge vehicles that accept AC charging through a compatible connector, but the charging speed depends on the vehicle's onboard charger limit. Compatibility and connector direction should be confirmed before purchase.

Do I need a three-phase supply for 7kW?

No. The 7kW model is designed for single-phase supply. Whether the site also has capacity for higher-power models is a separate question for the installer.

Can I install it outdoors?

The enclosure is specified as IP65 for this class. Final suitability depends on the mounting position, local rules and the installation design.

Does it support OCPP, RFID or DLB?

Function support depends on the selected model and configuration. These should be confirmed item by item rather than assumed.

What certificate documents are available?

Available documents include CB and UKCA-related attestation and inspection reports for listed wallbox models. Applicability should be checked by model, market and sales channel.

Can the wallbox be supplied with a customer brand?

OEM/ODM options such as logo, packaging, manual and selected configuration can be reviewed after the model, market and quantity are confirmed. Certification implications of brand and label changes should be checked first.

Which buyers usually choose the 7kW class?

Distributors, e-commerce sellers, installers, EV dealers, and residential or light-commercial project customers are the typical users of this power class, depending on the local grid and site conditions.
