Direct Answer
Choose 7kW, 11kW or 22kW only after confirming site power, phase, installation conditions, connector standard and the exact wallbox configuration required for the target market.
Key Takeaways
- 7kW, 11kW and 22kW represent different electrical and installation directions.
- Single-phase or three-phase site capacity should be confirmed before model selection.
- Smart functions and certificate documents must be checked against the selected model.
Detailed Explanation
Start with the site power conditionnWallbox selection is not only a product-title decision. A buyer should first confirm whether the installation site supports single-phase or three-phase power, the expected charger speed, the vehicle connector standard and the target market requirement.nHow to compare 7kW, 11kW and 22kWn7kW: common single-phase direction for home, EV dealer delivery and starter retail SKUs.n11kW: three-phase direction for markets where balanced charger and faster home charger are needed.n22kW: higher AC power direction for selected project, installer and distributor scenarios.nFunction review before quotationnConfirm cable or socket version, APP, Wi-Fi, Bluetooth, RFID, OCPP, DLB, MID, PEN protection and certificate document basis by exact model. Public product claims should match the selected configuration and market.

- Public function claims should follow the final configuration, not a generic family description.
Frequently Asked Questions
Is a 22kW wallbox always faster than a 7kW model?
Not in every installation. Available site power, vehicle onboard charging capacity and the selected configuration all affect the practical result.
Should smart functions be assumed for every wallbox model?
No. APP, RFID, OCPP, DLB, MID and other functions should be confirmed for the exact model and configuration.
