Frequently Asked Questions

Evnex chargers are compatible with all electric vehicle makes and models (bar a very small number of older models). The type of plug your EV uses (Type 1 or Type 2) will determine the specific charger model you need.

‍

Yes, we do. All Evnex chargers have a hardwired, CT-based Solar Diversion feature compatible with any solar installation.

When enabled, Solar Diversion will identify when unused locally generated energy is being exported to the grid, and instead use this for EV charging — slowing the charge to match the exported solar.

If a customer wishes to charge at full speed, but doesn’t have enough available solar energy, they can override this with our “Charge Now’ feature — topping up the remainder from the grid.

Evnex is a New Zealand-grown, manufactured, and supported company, with additional sales & support teams operating out of Sydney, Australia.

Evnex products and software are wholely developed in-house in Christchurch, New Zealand.

Our dedicated support teams draw from all areas of expertise — including electricians, engineers, and the people who have built the chargers from the ground up.

Our cloud connection further allows us to provide real-time troubleshooting, ensuring you can receive prompt, accurate support.

And you’ll always be dealing directly with us, the manufacturer. You’ll have a first-party contact for whatever you need — no middlemen.

Charger types and configurations will be dependent on the customer, their home, and their EV charging needs.

Key considerations are vehicle connector type (Type 1 or Type 2), home electrical supply (single or three-phase), vehicle charging spec (single or three-phase and kW), and charging behaviour (‘speed’ required).

Speak to our team to ensure we can tailor the best charging solution for any installation.

Our chargers are compatible with any home power supply, solar system, and all electric vehicles across New Zealand.

We offer clients full turn-key solutions from single charger installations to complex multiple charger dynamic-load groups — including single and three-phase options — all backed by Home Overload Protection ensuring that the charger(s) never exceeds the home’s maximum supply capacity.

We do our best to accommodate unique home configurations, ensuring you don’t have to turn away business.

Some homes may require custom installation solutions at additional cost to the client, and all Evnex chargers will require a connection to the cloud via an included 4G-sim or Wifi (or Ethernet - X-series only).

Faster – Evnex chargers are up to four times faster than traditional 8A chargers, ensuring customers can charge as fast as solar and grid-supply allows.

Safer – EV chargers are load-hungry appliances. Our Home Overload Protection automatically adjusts the charge rate when the draw is high, avoiding power supply overload.

Smarter – take advantage of cheaper electricity tariffs through our scheduling feature, and help clients to better understand and adjust their charging footprint with live grid emission data — showing where their energy is generated and its emission makeup.

Other than standard equipment, you’ll need an EV charging adapter/simulator, allowing you to engage the charger for functional and electrical testing. You’ll also need a suitable MFT to verify 6mA DC leakage detection (RDC-DD).

These tools are required across most EV charger installations, and aren’t unique to Evnex.

You’ll also require access to an Evnex installer account and the installation app for commissioning — which we will provide.

Our chargers are compatible with the majority of homes, and can be installed indoors or out. They can even be installed at homes with limited electrical spare capacity, thanks to our home-overload protection.

If you’re in an apartment, we recommend getting in touch with our sales team to discuss your options.

Yes, all Evnex chargers have solar integration as a standard feature.

When enabled, Solar Diversion will identify when unused locally generated energy is being exported to the grid, and instead use this to charge your EV — slowing the charge to match the exported solar.

If a you wish to charge at full speed, but doesn’t have enough available solar energy, you can override this with our “Charge Now’ feature — topping up the remainder from the grid.

We design, manufacture, and develop all our products at our HQ in Christchurch, New Zealand. We've been in the EV charging industry since 2014.

Yes, we install our chargers throughout Australia and New Zealand. Our network of local, friendly, professional electricians is well-trained on our products and can offer expert advice on all of your charging needs. Following your installation, we'll provide ongoing support — whether you're an EV driver, business owner, or fleet manager.

Yes, we offer three-phase charging for houses with three-phase power — we recommend you chat to our expert team to determine if this is the right fit for you. Our three-phase chargers are available in tethered and universal socket options.

We provide dedicated, local technical support seven days a week. You can reach our support team on 0800 395 007 or support@evnex.com. We also have extensive how-to guides and resources in the Evnex Knowledge Hub.

The charging speed of your vehicle depends on several factors, including the model of your vehicle, its battery size, the electrical capacity of your home, and the type of charger you use. We offer two charger options to suit your needs: a single-phase 7.4kW charger and a three-phase 22kW charger.

For personalised recommendations and to find the best solution for your charging needs, please contact our sales team. They’ll be able to help you choose the optimal setup for your vehicle and home.

We provide a 3-year warranty on the hardware and a 1-year warranty on installation. Please note that the installation warranty is only available if only available if you have Evnex handle your installation.

Once you've set up your preferences through the driver app, it’s as simple as plugging in and walking away! You can choose whether to charge immediately, schedule charging sessions, or set up to charge from excess solar.  

For detailed information on how to maximize the features of the app, check out the Getting Started and Smart Charging Features sections of the Evnex Knowledge Hub.

There are huge range of factors which affect battery lifespan, but, generally, AC charging (such as you would do at home) would have little-to-no effect on battery lifespan.

The grid provides power over Alternating Current (AC), but batteries need to be charged by Direct Current (DC).

AC chargers like ours supply AC to the car, where a small onboard inverter turns it into DC, ready to feed into the battery. This is suitable for places where your car will stay parked for hours, like your home, workplace or destinations (malls, supermarkets, attractions).

By contrast, DC chargers perform the conversion outside the car, which then feeds directly into the battery. With a large kerbside inverter, this allows for extremely rapid charging such as you need on a long journey, but the hardware and installation costs run to the tens or even hundreds of thousands.

‍

Yes, we can help with business or commercial building EV charging solutions, including multi-tenanted apartment buildings.

We provide EV charging software and tools for facility managers and body corporates to recoup charging costs.

You can find more information in this article about building a charging network for apartments and facilities.

It's definitely worth considering, as pre-wiring during a new build can result in a more cost-effective installation later.

If you have questions about preparing your new-build for an EV charger, take a peek at our pre-wire requirements guide.

Chargers can be installed directly on to any wall, or with mounting hardware for "standalone" positioning —such as a driveway. Our chargers are designed for both indoor and outdoor use.

They've been put through their paces in our testing environment — so they’re able to withstand even the harshest climates.

For individual homeowners and small businesses with a limited number of chargers, there is no subscription cost.

For business customers with multiple chargers and more complex requirements, we have paid subscription plans available.

Yes, however this does not need to be via Wifi and will work best via a standard cellular connection using a free, included 4G-SIM card.

Yes, you can. We offer a decommissioning service for customers who would like to relocate their charger to a new location.

Please get in touch with one of our team to arrange this service.
