Bonnet Bay is a planned 1970s–80s Sutherland Shire suburb wrapped around the Woronora River — split-level and brick homes on sloping, leafy blocks, some with water frontage. The terrain defines the work: sloping sites mean garages on different levels to the board, and the original 70s–80s panels often need modernising before a 7kW charger.
EV Charger Installation in Bonnet Bay
A standard 7kW single-phase EV charger install in Bonnet Bay typically runs $1,400–$2,500 fitted. Runs across split levels to a lower garage run $1,900–$3,200. Waterfront properties with marine-aware hardware run $1,800–$2,800. Older 70s–80s boards needing an upgrade combine at $3,200–$5,200.

App Setup & Handover
Before you order a charger online or sign with a national fixed-price installer, there are six things every Bonnet Bay EV owner should check.
- Your home is split-level on a slope: Standard in Bonnet Bay. The board and the garage are often on different levels — we route and quote the real run.
- Your switchboard is original to the 70s–80s build: Common here. It usually needs upgrading before a 7kW charger.
- You're on the Woronora River frontage: Some Bonnet Bay homes are. We use marine-aware hardware where salt and damp are a factor.
- Your garage is integral but below the house: Run distance and cable path affect cost — get the full run quoted.
- You've got roof space for solar: Many Bonnet Bay homes do. A solar-aware charger prioritises your own generation.
- You want it signed off: A CCEW and Level 2 install keeps insurance valid and transfers at resale.


Real overnight charging
A proper 7kW dedicated charger adds ~280 km of range overnight — versus ~50 km from a regular 10A wall socket. Big difference for daily commuters.
Switchboard upgraded properly
Where it's needed, we upgrade the board to AS/NZS 3000 — so the EV charger isn't the weakest link sitting on an original 1970s–80s panel.
Tesla app integration
Tesla Wall Connector pairs with your car, your home Wi-Fi and the Tesla app — scheduled charging, off-peak rates, household load monitoring.
Solar-friendly
Bonnet Bay's elevated blocks often have good roof aspect — Zappi, Wallbox Pulsar Plus and Schneider EVlink Pro can prioritise solar export so you charge from the roof, not the grid.
Future-proof for the next car
We size cable and sub-circuit for the bigger charger so when you upgrade to a 22kW dual-phase, the cable doesn't need to be ripped out and redone.
Insurance-grade compliance
CCEW + Level 2 install means your home insurer doesn't have grounds to refuse a claim if there's ever an electrical incident around the charger.
