Plug in to the future
Installing an EV charger at home offers convenience, cost savings, and faster charging.
Eliminate reliance on public charging stations, so you can wake up to full charge every morning. It’s a smart, eco-friendly investment that supports a seamless transition to powering not just your EV, but your home as well.
Home EV Charger Installation Process
Assessment
Omzen evaluates your home’s electrical system, including existing or additional solar and batteries required, for the most cost effective and efficient charger setup most suited to your needs.
Installation
We wire and install the EV charger ensuring the positioning is neat, accessible, symmetrical and compliant, whether it’s positioned indoors or outdoors.
Support
Omzen offers ongoing support and maintenance. Your charger will need to perform for years to come, and we can help to ensure optimal charger performance no matter its location and no matter the weather.
What is Bidirectional EV Charging?
How your car battery can power your house too.
A standard EV charger sends power one way, from the grid (or your solar panels) to your vehicle’s battery. A bidirectional charger allows power from your vehicle’s battery to flow back out and provide power to your house or even charge other EV’s.
Bidirectional charging is about more than just charging your EV. It turns your EV into a flexible power source that can power your home, get more value from your solar and support wider grid stability.
Benefits of a bidirectional charger:
Considerations for bidirectional charging:
Bidirectional charging offers greater flexibility and even more independence from the grid. By selling stored solar power to the grid via your EV’s battery in peak demand periods, wholesale electricity retailers, like Amber, offer higher feed-in tariffs.
Meanwhile, grid connection rules are becoming more uniform and more EV brands are being built to support bidirectional charging.
Most trusted EV charging brands
At Omzen Solar we pride ourselves on using the best products.
The Sigenergy EV chargers combine smart technology with high-performance charging to deliver a premium user experience, particularly when paired with Sigenegy home battery and inverter. Importantly, the Sigenergy DC charger provides bidirectional charging capability.
Both the AC and DC charger models feature dynamic load balancing, fast charging capabilities, and flexible installation options for both residential and commercial settings. With intuitive app control and real-time monitoring the Sigenergy chargers offer highly efficient energy management.
Best of all the DC charger is designed to stack seamlessly on top of Sigenergy batteries, making the installation neat, compact and as easy as stacking blocks.
The Tesla Wall Connector is a “Type 2” charger compatible with all EV’s, Plug-in Hybrid’s and eBikes sold in Australia. The Tesla Wall Connector provides a seamless integration and mobile app experience for Tesla customers who also own a Tesla vehicle or Tesla Powerwall battery.
The Myenergi Zappi EV charger delivers fast and efficient home charging with advanced smart features, particularly suited for those who do NOT have a Tesla or Sigenergy system. It integrates easily with all solar and battery systems, offers flexible charging modes, smart scheduling options and wireless monitoring to automatically take advantage of solar production. With a user-friendly interface, Zappi makes home charging convenient, reliable, and tailored to your energy usage.
The Enphase IQ EV Charger 2 is powered by innovative, cutting‑edge software. The system can initiate solar charging even in low light conditions through near real-time tracking of surplus solar. Charging patterns are optimised while saving money and minimising your carbon footprint. The rugged hardware is built to perform across all weather conditions and is perfect for outdoor or indoor use.
Charging your EV
How much power does an EV actually use and how much does it cost to charge?
Mains supply
Single phase supply – Sufficient for basic chargers
Three Phase supply – Required for fast chargers
Power usage
For an easy example using round numbers, consider the Tesla Model S that has a 100kWh battery and can travel approx 500km per charge in normal city driving conditions. That’s 20kWh per 100km.
Cost to charge from the grid
Charging entirely from the grid, using the AGL ‘Smart Saver’ plan of 25c per kWh as an example. It would cost $25 to charge.
Charging from solar during the day
Your solar system will need to produce enough to cover your home usage, plus your EV charger. If your home requires a 10kW system to cover usage during the day and your EV requires approximately an additional 5kW, you’ll need a system size of approximately 20kW to cover the load without drawing from the grid.
Charging from a home battery at night
If you arrive home from work after dark and want to charge your EV using solar power generated during the day and stored in your battery, you’ll need approximately 20kWh to charge your EV overnight. If you also want to cover additional home power usage in the evening you’ll need battery storage closer to 30kWh.
However, rather than depleting your home battery charging your EV in the evening, you can consider using your home battery to power your house and scheduling your EV battery to charge overnight at off peak rates.
There’s no cutting corners when it comes to quality
Omzen takes the extra time to install EV chargers the right way, not the easy way.
