EV Battery Charger Installation NSW — Tesla, Sigenergy & Evnex, by Licensed Electricians
The average NSW household drives around 15,000km per year. Charging that distance from public infrastructure or a standard 10-amp powerpoint costs $1,800–$2,400 annually. Charging the same vehicle from a dedicated home EV charger powered by your own solar system costs almost nothing.
Two market-leading charging platforms, installed by your own licensed electricians
ECR installs two market-leading EV charging platforms — the Tesla Wall Connector for Tesla owners and universal J1772 compatibility, and Evnex smart chargers for maximum solar integration intelligence. Both are installed by our own licensed electricians as part of a complete energy system or as a standalone upgrade.
EV owners who pair a home charger with an ECR solar and battery system typically reduce their total annual energy and transport costs by $3,500–$5,000+. Your car charges overnight from stored solar. No public charger queues. No per-kWh fees. No exhaust costs.
Tesla Wall Connector Gen 3
The Tesla Wall Connector Gen 3 is the definitive home charging solution for Tesla owners, and a premium choice for all EV drivers via J1772 adapter. Delivering up to 11kW of AC charging power, the Wall Connector adds approximately 70km of range per hour — turning an overnight charge into a full-range vehicle by morning.
Tesla Wall Connector Gen 3 — Key Specifications
- Up to 11kW AC charging output (72km range/hr)
- Wi-Fi connected — app scheduling, usage monitoring and remote control
- Universal compatibility — Tesla native + all EVs via J1772 adapter
- Indoor/outdoor rated — premium weather-resistant design
- Solar integration — schedule charging during peak solar production windows
- Paired with Tesla Powerwall: automatic solar-to-vehicle charging
- Multiple Wall Connectors can be load-balanced on a single circuit
- ECR: authorised Tesla Wall Connector installers
Evnex E2 & E3 Smart Chargers — Key Specifications
- E2: 7.2kW single-phase / E3: 22kW three-phase
- Solar optimisation mode — automatically charges from excess solar generation
- Real-time monitoring and scheduling via Evnex app
- OCPP 1.6 compliant — future-proof, interoperable protocol
- Load management — multiple chargers, multiple vehicles, smart priority management
- Suitable for residential, commercial hospitality and fleet applications
- Billing and access management for commercial applications
- Pairs natively with Sigenergy SigenStor for full smart energy integration
Evnex E2 & E3
Evnex has quickly established itself as the smart charger of choice for Australian homeowners who want to maximise the benefit of solar EV charging. The platform's cloud-connected intelligence allows real-time dynamic load management — automatically adjusting charging speed to match your solar surplus — so you're always charging from the sun first, and the grid only when necessary.
Why a dedicated EV charger matters
A standard powerpoint was never designed for continuous EV charging loads. A dedicated charger is faster, safer and smarter — and it lets you charge from your own solar first.
| Feature | Standard 10A powerpoint | Dedicated EV charger (ECR) |
|---|---|---|
| Output power | 2.4kW | 7.2kW – 22kW |
| Range added per hour | ~10 km | 40–72 km |
| Full charge (60kWh EV) | 25+ hours | 3–8 hours |
| Solar charging optimisation | None | Automatic solar-first charging (Evnex) |
| Safety rating | Not designed for continuous EV load | Purpose-built, thermally managed, licensed install |
| Smart scheduling | None | Off-peak tariff scheduling, solar peak scheduling |
| Monitoring | None | Real-time app — kWh, cost, sessions |
NSW Drive Electric Program: Commercial premises installing EV chargers may be eligible for up to $3,000 for Level 2 charger installation. Ask ECR about current eligibility when you request a commercial EV charging quote.
"We installed a Tesla Wall Connector alongside our Trina Solar system and Tesla Powerwall 3. Our car has now cost us nothing to run for 9 months. ECR handled the entire installation — one team, one invoice, no runaround. The integration between the Powerwall and the Wall Connector is seamless."— Chris & Emma W., Maitland, NSW
Your EV charging questions, answered
What EV chargers does ECR install?
ECR installs two market-leading EV charging platforms: the Tesla Wall Connector Gen 3 (up to 11kW, ideal for Tesla owners and universal J1772 compatibility) and Evnex E2 and E3 smart chargers (7.2kW single-phase and 22kW three-phase, with advanced solar optimisation intelligence). Both are installed by our own licensed electricians as part of a complete system or standalone upgrade.
Can I charge my EV using my solar panels?
Yes — and it dramatically increases your solar return on investment. Smart chargers like Evnex automatically detect when your solar system is generating surplus power and increase charging speed to absorb that free energy first. Paired with a home battery, your EV can charge overnight from solar stored during the day. ECR designs EV charging integration into every complete solar system quote.
Do I need a licensed electrician to install an EV charger?
Yes. EV charger installation requires a licensed electrical contractor — it involves a dedicated circuit, appropriate cabling, circuit protection and potentially a switchboard upgrade. ECR's licensed electricians handle all of this in-house, including electrical certificates of compliance. We do not use subcontractors for any part of the installation.
How long does EV charger installation take?
A straightforward residential EV charger installation typically takes 2–4 hours. If a switchboard upgrade or additional wiring is required, allow a full day. ECR provides a clear scope and timeline at quotation — no surprises on installation day.
