Book TodayA 7.4 kW single-phase smart charger for homes without solar — charge overnight on cheap power now, and unlock solar charging later with a software upgrade. No new charger, no second callout.
The E2 Flex is Evnex’s most affordable smart charger. It charges quickly and safely from the grid, comes with smart scheduling so you can top up on cheaper overnight rates, and has home overload protection built in.
Don’t have solar yet? The Flex is the smart pick. When you’re ready for solar down the track, it unlocks solar charging with a software upgrade — no new charger and no electrician callout needed. NZ-made, backed by a four-year Evnex warranty on top of our lifetime workmanship guarantee.
Plug in anytime and schedule charging for when power is cheapest. Wake up to a full battery every morning.
A one-off software upgrade unlocks solar charging later. No new hardware, no return visit from the sparky.
Built-in home overload protection automatically slows or pauses charging when your home’s power use is high.
Every Evnex charger comes with the Evnex app. Set a schedule so the car fills up on the cheapest power overnight, follow a live charge from your phone, and see exactly what each session cost and where the power came from. If it ever needs a hand, Evnex can support the charger remotely.
The quick answer on cars, solar and batteries, and the power supply the E2 Flex needs.

*Range per hour is the maker’s own figure. Your car sets the real speed: many EVs accept 7 kW or 11 kW on AC, so a 22 kW charger only charges at 22 kW if your car can take it.
Whatever charger you choose, the install standard is the same. Here’s what’s included as standard:
We're an Evnex Certified Installer. We fit the Evnex range every week and know it inside out — set up, tested and registered to the app properly, the first time.
Before we lock in your quote we confirm your home Wi-Fi reaches the charger. If it doesn’t, we quote the 4G-capable model separately — decided upfront, never swapped on install day.
Yes. A one-off software upgrade bought from Evnex switches solar charging on. There’s no new charger and no electrician visit.
If you don’t have solar and aren’t planning it soon, the Flex does everything you need: scheduling, app control and overload protection. If you already have solar, or want it working from day one, get the Core.
Almost certainly. Every new EV sold in Australia uses a Type 2 plug. If you drive an older Japanese import with a Type 1 plug, tell us the model and we’ll check which charger and cable you need.
Yes. Set a schedule in the Evnex app and the car charges when your off-peak rate kicks in.
We check that before your quote is locked in. If the signal doesn’t reach, we quote the 4G-capable E2 Plus separately so you can decide upfront. We never swap models on install day.
Not always. The charger needs its own circuit with a 32 A Type A RCBO. If your board is old, full or can’t safely take it, we’ll tell you before you book and put the work on your quote. No surprises on the day.
With a calibrated EV simulator. It loads the charger under real charging and fault conditions. We never plug into your car to test. We also do full AS/NZS 3000 testing and lodge the CCEW through the Building Commission NSW eCert portal.
Evnex covers the charger with a 4-year warranty for home installs. On top of that, our workmanship is guaranteed for life.
Every home is different: the distance from your switchboard, the wall, and whether the board needs work all change the job. We give you a free, fixed price on a written quote, with no callout fee. What’s on the quote is what you pay.
“I recently had Expert Electrical Services install my Evnex EV charger, and I could not be happier with the quality of work and professionalism. The final result is clean, safe, and perfectly set up.”
