7kW Single-Phase vs 11kW/22kW Three-Phase Home Wallbox Installation Guide for BYD Owners

On-Road Impressions, Efficiency & Setup Details

  • BYD Atto 3, Seal, Sealion 6 & Shark 6 (Standard RHD): 7 kW Single-Phase AC (32A) -> Adds ~11–12% SOC per hour.
  • BYD Seal, Dolphin Design & Sealion 7 (UK/EU 3-Phase Builds): 11 kW Three-Phase AC (16A per phase) -> Full charge in ~6.5 hours.

For 95% of households, a 7.4 kW smart solar-aware wallbox (Zappi, Fronius Wattpilot, Evnex, or Tesla Gen 3 Wall Connector) easily fills the battery from 20% to 100% during a 6-hour overnight off-peak window!

Every EV and PHEV platform has trade-offs, and seeing real long-term feedback like this is why independent owner forums are way more useful than brochure numbers.

Has anyone here compared this behaviour before and after the latest DiLink OTA firmware update? Mine felt noticeably smoother in low-speed traffic afterwards.
