Evnex E2 EV Charger Review: A Smart, Solar-Friendly Charger Made for Australia

As electric vehicle (EV) adoption grows in Australia, so does the demand for smarter, cleaner, and more reliable home charging solutions.

One standout in this space is the Evnex E2 EV Charger, a solar-integrated, Kiwi-engineered charger that brings powerful features, sleek design, and real-time energy awareness to the garage wall. So, how does it stack up in real-world conditions? We put it to the test.

About the Company: Kiwi Innovation Across the Pond

Evnex is a New Zealand-based company with a clear mission: to build the cleanest, most intelligent EV chargers possible. From the printed circuit board (PCB) to final assembly, every part of the E2 charger is made in Christchurch.

Sustainability runs deep in their ethos. The charger’s external housing is made from bio-plastic, and it’s available in four colours inspired by the natural landscapes of New Zealand.

Design and Build Quality

The Evnex E2 is refreshingly slim and well-built. While the outer casing feels slightly plasticky (like many chargers), its internal layout is smartly designed for easy wiring. Despite the compact design, installers report a straightforward and tidy installation process.

The minimalist design makes it suitable for both indoor garages and sheltered outdoor installations.

Installation Experience

Electricians have praised the Evnex E2 for its ease of wiring, despite the unit’s compactness. While some chargers sacrifice accessibility for aesthetics, the Evnex strikes a good balance.

An installer-friendly internal layout, combined with solid hardware and thoughtful engineering, makes it a go-to for professionals, especially when integrated into solar setups.

Key Features That Set It Apart

When it comes to choosing an EV charger, features matter, especially for those looking to future-proof their investment and maximise solar savings. The Evnex E2 doesn’t just tick the standard boxes of charging reliability and sleek design, it goes well beyond with smart integrations and thoughtful touches that make daily use smoother, more sustainable, and more efficient.

From robust solar surplus charging to built-in 4G connectivity, the Evnex E2 is packed with innovations that put it in a class of its own. Below, we break down the standout features that make this charger ideal for tech-savvy EV owners, solar-powered homes, and environmentally conscious drivers.

Solar Surplus Charging – Without Wi-Fi Drama

Unlike many EV chargers that rely on Wi-Fi to detect solar surplus, the Evnex E2 uses a hardwired CT clamp connection for much greater reliability and real-time responsiveness. This makes solar charging smoother and less prone to dropouts, especially important in rural or fringe network areas where Wi-Fi is flaky.

Built-in 4G Connectivity

Forget about Wi-Fi limitations altogether. The Evnex E2 includes a 4G SIM card, providing always-on connectivity for remote support and firmware updates. If there’s a problem, Evnex can access the unit directly, no need for you to reconnect your Wi-Fi or even be at home.

Tesla Tap-to-Charge Feature

A recent firmware update added one of the coolest usability features yet: tap-to-open and close the Tesla charge port with the button on the Evnex cable. No more reaching for your phone or fiddling with menus, just walk up, press, and charge. A small touch, but a big daily win.

Performance Under Heat and Load

Thermal performance matters in Australia’s climate, and the Evnex passed our heat chamber test with flying colours.

Charged at 32 amps initially, the unit reached 38°C internally and eventually derated to 25 amps, well within industry norms. For comparison, the highly regarded Zappi charger dropped to 6 amps under similar conditions. Even Tesla and Fronius chargers showed similar derating patterns to the Evnex.

The takeaway? Evnex handles heat as well as, if not better than, most top-tier chargers.

App Experience: Smart, Simple, and Insightful

The Evnex app is among the most polished we’ve seen. Key features include:

• Live solar tracking and carbon intensity monitoring
• Charge cost calculator: Input your electricity buy and feed-in rates
• Charge scheduling and solar prioritisation modes
• Real-time environmental data: Ideal for fleet tracking or eco-conscious charging

One unique standout: the app can show the real-time percentage of renewable energy in your local grid – a rare and valuable insight into your carbon footprint during each charge.

Smart Charging & Solar Integration

This is where Evnex really shines. While other chargers (like Tesla’s Wall Connector) offer limited solar integration unless paired with their proprietary batteries or inverters, the Evnex E2 works out of the box with solar surplus.

Its hardwired data connection gives it a responsiveness edge, allowing it to start and stop charging quickly based on available solar. It’s a smarter choice for homes with rooftop solar but no Tesla Powerwall or Fronius ecosystem.

Who Should Buy the Evnex E2?

While the Evnex E2 boasts impressive features, it’s not a one-size-fits-all solution. Like any charger, its value depends on your home setup, solar system, and even the brand of your electric vehicle.

This section helps you determine whether the Evnex E2 is the right fit for your needs. We’ll outline the types of users who will benefit most, such as those with rooftop solar, Tesla drivers without Powerwalls, or fleet owners tracking carbon emissions, as well as those who may be better off with a charger more tightly integrated into specific inverter ecosystems.

Ideal For:

• EV owners with solar panels who want reliable solar surplus charging
• Households without a Tesla Powerwall or Fronius inverter
• Environmentally conscious users who want carbon tracking
• Tesla car owners who want smart features (like the tap-to-charge cable)

Not Ideal For:

• Homes that are already tightly integrated into Tesla or Fronius ecosystems
• Installations where running a hardwired CT clamp isn’t feasible

Pricing and Availability in Australia

The Evnex E2 is priced competitively in the mid-range bracket. While not the cheapest on the market, it offers exceptional value when you consider its solar features, 4G connectivity, and intelligent app integration.

Availability may vary depending on your installer. While some solar companies prefer to sell chargers tied to their inverter brands (e.g., Tesla or Fronius), Evnex is available through select resellers and can be installed independently.

Final Verdict: Is It Worth It?

The Evnex E2 EV Charger is a premium, smart, and solar-savvy charging solution that competes with, and in many ways surpasses, the likes of Tesla and Fronius for standalone charger functionality.

With standout features like 4G connectivity, hardwired solar surplus integration, tap-to-charge Tesla functionality, and real-time carbon tracking, it’s an excellent choice for modern Australian EV owners, especially those already riding the solar wave.

Pros:

• ✅ Reliable solar surplus charging
• ✅ Built-in 4G for remote support
• ✅ Sleek, slim design
• ✅ Powerful, intuitive app
• ✅ Environmentally conscious production
• ✅ Excellent customer support

Cons:

• ❌ Not ideal for homes deeply integrated into Tesla or Fronius ecosystems
• ❌ Requires a hardwired setup for solar tracking

Bottom Line

If you’re an Australian EV owner looking for a reliable, future-ready charger that plays nice with solar and doesn’t lock you into a specific brand ecosystem, the Evnex E2 is one of the best chargers on the market today.
