The challenge
Individual 7.4 kW wallboxes across 180 homes would collectively demand far more than the estate distribution was designed for, and buyers wanted to charge from their own solar.
Solution
- One 7.4 kW AC wallbox per home, installed during construction
- Estate-wide load management limiting aggregate demand
- Home energy storage on the larger plots with solar-surplus charging
- Single app for the wallbox and home battery
Implementation
1Estate-wide load study with the developer
2Standardised installation design for all house types
3Handover with per-home documentation
Outcome
- 180 homes were EV-ready at handover
- Aggregate estate demand remained within the distribution capacity
- Wallbox and battery controlled from a single app
