An indoor installation is generally the better option if you have a secure, ventilated garage. It offers greater protection from the weather, improved security, and neater cable storage. For homes without indoor space, an outdoor installation remains a practical choice when weatherproofing and safety measures are followed. Choosing a charger with at least an IP65 rating and protecting cables is essential. In both cases, installation must be carried out by a licensed electrician, and the charger should be certified for Australian conditions to ensure safety, compliance, and long-term performance.
Where Should I Install My EV Charger? Indoor vs Outdoor Placement Explained
As the ownership of electric vehicles (EVs) continues to rise in Australia, more households are installing EV chargers at home. While selecting the right charger is important, deciding where to install it is equally crucial. The choice between indoor and outdoor placement affects convenience, safety, performance, and ongoing maintenance.
Indoor EV charger installation – is it the better option?
Benefits of indoor placement
Placing an EV charger inside a garage or enclosed space provides strong protection against harsh weather such as direct sunlight, heavy rain, or hail. This shelter extends the lifespan of the charger and ensures reliable performance over the years. Indoor setups also improve security by reducing the risk of theft, vandalism, or accidental damage. In addition, cable management is easier, keeping charging leads neatly stored and less exposed to daily wear.
Considerations before installing indoors
Before committing to an indoor installation, check whether the location offers easy vehicle access for charging. Adequate ventilation is essential, as chargers can generate heat during operation. Depending on the distance from the switchboard, additional cabling or electrical upgrades may be required to ensure safety and efficiency.
Outdoor EV charger installation – why it may be more practical
Advantages of an outdoor setup
For homes without a garage or covered parking, installing an EV charger outdoors is often the most practical choice. Outdoor chargers can be accessed by multiple vehicles, making them ideal for driveways, shared parking spaces, or multi-tenant properties. They also provide easier access for visitors with EVs, without requiring them to enter the home or garage. When installed correctly, outdoor chargers can perform just as reliably as indoor units.
Key requirements for outdoor installations
Outdoor setups require weather-resistant chargers that meet Australian conditions. A charger with at least an IP65 rating offers protection against rain, dust, and sun. Proper mounting is important to avoid direct exposure to extreme elements. Charging cables should also be securely stored when not in use to prevent wear, tangling, or accidental damage.
What to consider when choosing between indoor and outdoor
Climate and environmental conditions
Local climate plays a major role in deciding the most suitable installation type. Coastal properties face corrosion risks from salty air, while inland areas may experience extreme heat and dust. Prolonged exposure to direct sunlight can damage charger components, making UV protection essential. Understanding how temperature variations affect charger efficiency is critical in choosing the best option.
Safety and compliance
Regardless of placement, all EV charger installations must comply with Australian standards. This includes the use of an RCD (Residual Current Device), circuit breaker, and proper wiring. Installation must be carried out by a licensed electrician to ensure safety, compliance, and performance. Meeting these requirements also protects warranties and insurance coverage.
Accessibility and user experience
The charger should be installed in a location that allows convenient daily use. There should be sufficient space for parking and moving around the vehicle without straining cables. If multiple vehicles will use the charger, placement should allow easy access from different angles.
Installation and maintenance costs
Costs can vary depending on placement. Indoor chargers located near the switchboard may be cheaper to install due to shorter cabling needs. Outdoor installations can involve higher costs for trenching, wall mounting, or weatherproof enclosures. Factoring in these costs early helps avoid unexpected expenses.
Our recommendation for Australian homeowners
Conclusion
The decision between indoor and outdoor EV charger installation depends on your property layout, local climate, and personal needs. Indoor setups generally provide stronger protection and security, while outdoor chargers can work just as effectively with proper weatherproofing and safety measures. By weighing your location, accessibility, and budget, you can choose a setup that supports safe and efficient EV charging for years to come.
Freequently Asked Questions
Where is the safest place to install an EV charger?
The safest place is indoors in a secure garage or carport, where the charger is shielded from weather and tampering. A properly weatherproofed outdoor charger can be just as safe if it meets Australian standards.
Do outdoor EV chargers need special protection?
Yes. Outdoor chargers should have an IP65 or higher rating to withstand rain, dust, and UV exposure. They should also be securely mounted and, if possible, shielded from direct sunlight.
Can I install my EV charger myself?
No. Installation must be performed by a licensed electrician to comply with Australian safety standards and to maintain warranty protection.
Does the charger’s location affect charging speed?
The location itself does not affect speed, but long cable runs or poor wiring can reduce efficiency. A professional installation ensures correct cabling for optimal performance.
Which is cheaper to install, indoor or outdoor?
Indoor installations are often less costly if the charger is close to the switchboard. Outdoor setups may involve extra work, such as trenching or protective enclosures, which increase costs.
