The Best EV Chargers For Home Use

There are a number of smart home chargers on the Australian market. Here are my top picks based on installer experience and product reliability.

Goodwe’s HCA series launched in 2022 and is compatible with all EV brands. It allows for smart solar charging and is available in single-phase (7 kW) and threephase (12/22 kW). It also comes with an extended warranty backed by an office in Australia.

Level 2

Most ev chargers come with a standard 10 Amp Type 2 plug for AC charging at home and at public stations. There are also adaptors available to enable your EV to charge with other types of plugs.

Most people will charge their EV at Level 1 public chargers, usually located in shopping centres and restaurants. These can add a full charge overnight for most small to medium battery EVs but will not be fast enough for the average daily commute or road trip.

Installing a Level 2 charger at home is the best long-term solution to increase your EV range and save money on fuel. However, it will cost between $1,000 and $3,000 including installation by a licensed electrician. Look for a charger that features a cable management system that enables you to coil and hang the cables off the connector, out of the way when parking the car. This will keep them away from the elements and help prevent damage.

Level 3

Slow AC charging using a standard 240-volt Australian household outlet can replenish most EVs’ driving range overnight. It’s cheaper than fast DC charging and generates less heat, which is better for battery longevity. This is the most common option for charging at home and can also be used as a backup in the event of long commutes.

A single-phase 7kW EV charger at home can guarantee enough range to get most people to work and back again the next day. Combined with solar power, this can reduce charging costs even further.

Choosing a charger that’s designed for Australia’s climate is important. Having the same provider for both the charger and installation can simplify warranty claims if anything goes wrong. The UK-made Zappi V2 charger from Myenergi and EVSwitch is a great choice. It comes with a 7kW home charger and 5m Type 2 cable, features three modes for maximum efficiency and uses renewable energy whenever possible. It also has an easy-to-use free EV Charging app for remote management, monitoring and scheduling.

Combo

Electric Vehicles (EV) are here to stay and are transforming the way we travel across Australia. However, the EV revolution raises many questions about charging times, driving ranges, and how to find public chargers across the country.

For a stress-free trip, an EV owner needs to ensure that their home charger can keep up with charging demands. Look for a home EV charger with Wi-Fi connectivity, which makes it easy to monitor usage and receive notifications. A good EV charger will also feature enhanced load balancing, which adjusts the power distribution to prevent circuit overload.

When shopping for a home charger, look for one that is compatible with your electricity tariff, solar system, and battery. The Wattpilot EV Charger costs about $1,800before installation and integrates seamlessly with Fronius inverters. It is available as both a hardwired and portable option and features fast charging. The best ev chargers Australia are rated for reliability and come with a 5-year warranty.

Solar

We've rated the best chargers available for home use based on their features, reliability and pricing. Level 2 charging at home is more expensive but offers much faster charging and the ability to co-ordinate with your solar system and home battery to maximise savings. A garage or off-street parking is required to install a level 2 charger at your house.

ABB’s EV chargers are available in 7kW single phase and 22kW three-phase for home and business use. They can be tethered or untethered and come with an EV cable. ABB's EV chargers can be supplied and installed by your Enphase Energy microinverter installer as part of a new solar system or retrofitted to existing systems.

SMA offer an EV charger that integrates with their microinverters (both older and newer models). This smart feature monitors how much excess solar you're exporting and diverts the surplus to your car battery to charge your vehicle using the cheapest electricity in Australia: behind-the-meter Australian solar.

THREE-PHASE NETWORK INVERTERS SO FAR SOLAR

7kw 3 Phase Solar Inverter is used in solar stations that operate without batteries. All generated energy immediately goes to the 3-phase network for consumption. When the power consumption decreases, the generation power decreases accordingly. It is monitored by current sensors & the ARPC unit. It is necessary so that the excess generated energy does not go into the network and is not counted by the meter as consumed. Domestic electricity meters are one-way and do not know how to subtract. With the introduction of the "green tariff", when it becomes possible to sell surplus electricity to sales companies, then these restrictions will disappear, and it will be possible to earn additional money.

Prerequisites for work

A feature of the work of network inverters is the need for a regular electrical network.

The line of 3-phase inverters consists of devices of different capacities: from 1 to 66 kW. Almost every inverter has 2 independent MPPT trackers built-in with the possibility of uneven power distribution, except the 55 and 66 kW models, which have 3 MPPT trackers.

The presence of the WI-FI module allows you to connect the inverter to the Internet and monitor the system parameters after registration on the manufacturer's website.

Three-phase solar edge inverter is very common in industrial enterprises, office buildings, business centres, country houses, or other facilities where there is electricity consumption in the daytime & there is an external power grid. The use of network inverters can significantly reduce energy costs, and the payback is only from 1 year to 5 years.

Currently, an increasing number of network operators in various countries are setting limits on the return of energy to the urban network from photovoltaic modules. Thanks to the dynamic reduction in power, Solaredge Inverter offers a solution for optimal management of power generation and output. The inverter first supplies electricity to the household consumers in your home & then reduces the output power of the system to the maximum allowable value allowed by the network operator.

How much does it cost to buy and install a home charger

As the economy develops, people's incomes rise and the cost of cars falls, and basically every household has at least one car in use. However, while the car brings convenience to human beings, it also brings a series of problems. The most serious ones are the excessive consumption of energy such as oil and natural gas, as well as the energy and environmental problems of vehicle exhaust emissions. Therefore, it is necessary to limit vehicle exhaust emissions and to find alternative energy sources for oil. At present, the best solution to such problems is to vigorously popularize electric vehicles.

As the country's preferential policies and the use of electric vehicles have become an inevitable trend, more and more families have begun to use electric vehicles. Inexpensive and environmentally friendly are significant advantages of electric vehicles, and one of the current problems of electric vehicles is charging. Because electric vehicles have only been developed for a few years, and the number of public electric vehicle charging piles is small, in order to avoid queuing, many families decide to buy home electric vehicle chargers.

Buying Advice for Home EV Chargers

1. At present, the technology of household AC chargers is relatively mature, and the cost has been reduced. But at the same time, due to technological iterations, the battery capacity of electric vehicles continues to increase, and the power of chargers continues to increase, which further increases technical requirements and costs. Therefore, home EV chargers cannot simply be purchased based on price.

2. The purchase of home chargers should not only consider the cost of the pile, but the most expensive is actually in the installation, the larger one is the cable. At present, the official price of the high-level charging pile set on the market is 8,000 yuan, and the cable length that comes with it is also the highest in the industry, 70m. From my actual experience, due to the consideration of wiring and wiring problems, most of the users' cables require length (from the state grid meter to the charging pile installation location, the user is responsible for it, and the state grid is not responsible for it) is not will be less than 50m. At this length, the cost of the cable is almost certainly higher than that of the charger. Therefore, once again, you must fully understand the installation cost and material cost when purchasing a charger.

3. At present, 3.5kw charging piles have been almost eliminated, there is no need to continue to choose, and the cost is not much different from 7kw, so the mainstream still chooses 7kw. The 11kw charging pile is a three-phase AC, and it is necessary to apply for the installation of a three-phase large electric meter to truly achieve 11kw power. Remember this. In addition, most of the new energy vehicles on the market currently do not support three-phase AC charging, and some require additional money to upgrade the charging module to support it. Therefore, please understand the condition of your own vehicle before purchasing.

4. According to statistics, 50% of the spontaneous combustion of new energy vehicles occurs in a stationary state after charging. Therefore, it is strongly recommended that you do not overcharge the battery. Generally, it can be charged to more than 80%, but not more than 90%. When buying a charger, it is better to choose a high-quality brand, and the charger with a larger shipment is more secure. When installing, please choose a service provider with installation qualifications, the construction is more standardized, and the materials used are more secure.
