So you’ve bought (or are about to buy) an EV. Congratulations — your fuel bill just dropped by about 80%, and you never have to visit a servo again. But there’s one decision left that genuinely matters: what charger are you going to install at home?
At Focus Group Electrical, we’ve been installing EV chargers for Sydney homes long enough to have strong opinions on which brands actually work, which are overpriced, and which suit different households. This is the guide we wish every customer had read before calling us. We’ll cover the four brands we install (Ocular, EVnex, Zappi and Tesla), how to pick between them, what installation actually costs in Sydney, and the questions everyone asks.
If you just want a quote — we offer fast free quotes here. Otherwise, grab a coffee and read on.
Why You Want a Home EV Charger (Not Just the Trickle Lead)
Most EVs come with a 10-amp trickle lead that plugs into a normal household power point. It works — but slowly. We’re talking 10–15km of range per hour at best, which means a fully empty Tesla Model Y (455km range) takes about 35 hours to fully charge from flat. Plug into a proper home charger and you’re looking at 4–6 hours.
More importantly, the trickle lead pulls 10 amps continuously through a household circuit that wasn’t designed for that kind of sustained load. Many sparkies (us included) consider this a fire risk, especially over years. A dedicated, hardwired charger on its own circuit is much safer.
Beyond safety and speed, a proper home charger gives you:
- Faster charging — wake up to a full battery every morning
- Smart features — schedule charging for cheap off-peak times, track energy use, get notifications
- Solar integration — charge from your rooftop solar (with the right charger)
- Resale value — a hardwired EV charger is now a feature buyers look for
- Peace of mind — no extension cords trailing through doorways
What to Look For in a Home EV Charger
Before we get to the brand-by-brand comparison, here’s what actually matters when picking a charger:
Charging Speed (kW)
Most home chargers are either 7kW (single-phase) or 22kW (three-phase). 7kW adds 40–50km of range per hour. 22kW adds up to 120km of range per hour but requires three-phase power at your home — which most Sydney houses don’t have. More on this below.
Type 2 Connector
Every EV sold in Australia uses the Type 2 connector. Any charger with a Type 2 plug works with every EV — Tesla, BYD, Polestar, Kia, Hyundai, MG, Volvo, BMW, Mercedes-Benz. Don’t worry about charger-EV compatibility.
Tethered vs Untethered
Tethered chargers come with a built-in cable (usually 5–7m). Untethered chargers don’t — you use the cable that came with your EV. Tethered is more convenient for daily charging; untethered looks tidier on the wall and is slightly cheaper. We install both.
Smart Features
All four brands we install offer smartphone apps with scheduling, energy monitoring, and cost tracking. The differences are in the depth of features, solar integration, and software polish.
Solar Compatibility
If you have rooftop solar (or plan to), some chargers can divert excess solar export directly into your EV — meaning you’re effectively driving on free sunshine. This is a game-changer if you have solar. The chargers that do this best are Zappi and EVnex.
Warranty
Industry standard is 2–3 years. Tesla and EVnex both offer 4 years, the longest in the Aussie market.
7kW vs 22kW: Which Speed Do You Actually Need?
This is the question we get asked most often, and the honest answer is: most Sydney homes are best served by a 7kW single-phase charger. Here’s why.
7kW Single-Phase
Adds around 40–50km of range per hour. If your EV is at home for 8+ hours overnight, you’ll wake up to a full battery — even with a fairly empty car. The vast majority of Sydney homes only have single-phase power, which means 7kW is your maximum.
Best for: 95% of households.
22kW Three-Phase
Adds up to 120km of range per hour. But — and this is the catch — this requires three-phase power at your home. Most Sydney houses are single-phase. Upgrading to three-phase can be costly depending on what’s involved with Ausgrid, and it’s rarely worth it just for a faster charger.
Worth it if: You already have three-phase power, you have multiple EVs, or you do unusually high mileage and need to top up quickly during the day.
If you’re unsure, contact us and we’ll quickly check your switchboard and tell you what’s realistic.
The 4 EV Charger Brands We Recommend
There are dozens of EV charger brands sold in Australia. We’ve installed enough of them to have strong opinions about which work, which are overpriced for what you get, and which suit different households. These are the four we actively install and recommend:
| Brand | Origin | Best For | Solar | Warranty |
|---|---|---|---|---|
| Ocular LTE Plus | Australia | Best value, local support | IQ Home Solar model | 2 years |
| EVnex E2 | New Zealand | Premium build, longest warranty | Standard on E2 Core/Plus/X22 | 4 years |
| Zappi v2.1 | United Kingdom | Solar households | Best in class — works with any inverter | 3 years |
| Tesla Wall Connector | USA | Tesla owners + value all-rounder | Limited | 4 years |
Ocular — Best Value, Aussie-Made
Australian-owned with locally answered phones. Offers 7kW or 22kW, IP66 outdoor rating, full smart-charging features, and a CT clamp solar diversion model (IQ Home Solar). Sharper price than the alternatives, with proper local support.
Best for: Sydney homes that want smart features at a fair price.

EVnex — Premium Pick, Longest Warranty
Designed and built in New Zealand, with Australian Sydney-based support. Polestar’s preferred Australian charger, 4-year warranty (longest on the market), built-in 4G on most models, and four colour options. The E2 Plus has dedicated Tesla integration, including reading your battery state of charge directly in the app.
Best for: Drivers who want the best build quality and support, regardless of brand.

Zappi — Solar Household Champion
UK-engineered by myenergi. The most popular solar EV charger in Australia, and rightly so. Three intelligent charging modes (Fast, Eco, Eco+) with the unique Eco+ mode that charges your EV only when your solar is exporting — pure free-sunshine charging. Works with any solar inverter via CT clamp.
Best for: Anyone with rooftop solar who wants to maximise self-consumption.

Tesla Wall Connector — Tesla Owner’s Pick & Surprise Value Play
Made by Tesla. Sleek, premium design, generous 7.3m cable, up to 22kW on three-phase, 4-year warranty, and one of the lowest unit prices on the market (~$800). Deep integration with Tesla vehicles. Works with any non-Tesla EV too via universal Type 2 — but you’ll miss the Tesla-specific app integrations.
Best for: Tesla owners (no-brainer) and value-conscious non-Tesla owners.

Got Solar? Read This Before You Choose
If you have rooftop solar (or plan to install it soon), the right EV charger can effectively give you free driving. The catch: not all chargers do solar properly, and the quality varies hugely.
Here’s how the four brands stack up for solar:
- Best in class: Zappi — the gold standard. Works with any inverter, three intelligent modes, can charge purely from solar export.
- Excellent: EVnex E2 Core, E2 Plus, X22 — built-in solar smarts standard, well-implemented, beautiful app.
- Good: Ocular IQ Home Solar — solid CT clamp solar diversion, sharper price than EVnex/Zappi.
- Limited: Tesla Wall Connector — has some smart load features but doesn’t do dedicated solar diversion. If solar charging is a priority, look elsewhere.
Our typical recommendation for Sydney solar homes: Zappi if you want the best, EVnex E2 Core if you want premium build with solar smarts, or Ocular IQ Home Solar if you want excellent value.
How EV Charger Installation Actually Works
Here’s exactly what happens when you book us for an installation. The process is the same regardless of which brand you’ve chosen:
- Site assessment — we check your switchboard for capacity, look at your preferred charger location, measure the cable run, and confirm whether you need any other work
- Switchboard prep — if your board needs a switchboard upgrade or new dedicated circuit, we’ll quote it upfront. Never as a surprise on install day
- Mounting and cabling — we wall-mount the unit, run cable through the wall cavity (or in tidy surface conduit), and install a dedicated circuit with RCD protection
- Configuration — we connect to your home WiFi, set up the relevant app on your phone, configure solar (if applicable) and any brand-specific features (e.g. CT clamp setup for Zappi, Tesla account pairing for Tesla Wall Connector)
- Testing and handover — full charging session with your EV, walk-through of the app, and handover
- Compliance certificate — Certificate of Compliance for Electrical Work (CCEW) for your records, insurance and the manufacturer warranty
Most installs take 3–5 hours. We do them in a single visit wherever possible, with no sub-contracting — the same Focus Group sparky who quotes your job is the one installing it.
Common Mistakes Sydney EV Owners Make
After hundreds of installs, these are the patterns we see — and the things we wish more customers knew before they bought a charger:
1. Buying the Charger Before Getting a Quote
We see this constantly. Someone buys an EV, immediately orders a charger online, then discovers their switchboard needs an upgrade. Always get an installation quote first — it tells you exactly what your install will cost and whether the charger you’re eyeing is the right one for your home.
2. Choosing 22kW When 7kW Would Do
We mentioned this above, but it’s worth repeating. Going from single-phase to three-phase can be a big jump in cost in Sydney. Unless you have a genuine reason for 22kW (multi-EV household, very high daily mileage, three-phase already installed), 7kW is plenty.
3. Ignoring Solar Integration
If you have solar — even a small system — and don’t pick a charger with proper solar smarts, you’re leaving money on the table every single sunny day. Zappi and EVnex are the obvious picks here.
4. Going for the Cheapest Install
EV chargers run high current continuously for hours at a time. A bad install isn’t just inconvenient — it’s a fire risk. Make sure your installer is properly licensed, insured, and provides a Certificate of Compliance (CCEW). If anyone offers cash-only or a price that seems too good to be true, walk away.
5. Not Considering Future Needs
Buying a second EV in the next 5 years? Planning to add solar? Putting in a battery? It’s worth thinking about all of this now, because some chargers handle multi-EV setups (Tesla Group Power Management) or solar integration (Zappi, EVnex) much better than others.
