Can Your EV Power Your Home? Meet the SolaX Binary Series Bidirectional EV Charger
Updated: 3 days ago
Electric vehicles are changing the way Australians drive. But the next step could change the way we power our homes too.
Imagine charging your EV using excess rooftop solar, then using some of the energy stored in your vehicle to support your home when you need it.
That’s the idea behind bidirectional EV charging, and the SolaX Binary Series Smart AC Bidirectional EV Charger brings this technology into the home energy ecosystem.
At DSW Energy, we help Australian homeowners build smarter energy systems that bring solar, battery storage and EV charging together. For households considering an EV or looking to get more from their existing solar system, bidirectional charging opens up exciting new possibilities.
What Is a Bidirectional EV Charger?
Most traditional EV chargers work in one direction: electricity flows from your solar system or the grid into your electric vehicle.
A bidirectional EV charger can allow that energy to flow both ways.
With Vehicle-to-Home (V2H) technology, energy stored in a compatible EV may be used to help supply electricity to the home when required.
This means your EV has the potential to become more than transportation. It can become another part of your home's energy management system.
Meet the SolaX Binary Series
The SolaX Binary Series Smart AC Bidirectional EV Charger is designed to integrate compatible electric vehicles into a broader home energy ecosystem.
One of its key advantages is its AC-side architecture, providing homeowners with another pathway to integrate EV charging with compatible SolaX solar and energy management equipment.
Depending on your EV, inverter and overall system configuration, the Binary Series can help manage when your vehicle charges and when stored energy is made available to the home.
For homeowners already using solar or planning a complete solar, battery and EV setup, this creates an opportunity to manage more of their energy from one connected ecosystem.
Why Bidirectional Charging Is Exciting for Australian Homes
Make Better Use of Your Solar
Your rooftop solar system often produces its most energy during the day, when household electricity demand may be relatively low.
Instead of relying only on exporting excess solar energy to the grid, a compatible system can use available solar generation to charge your EV.
That stored energy can then potentially be used later, helping you get more value from the electricity generated on your own roof.
Smarter Energy Use
Electricity demand and tariffs can change throughout the day.
A smart home energy system can help you decide when it makes sense to charge your EV and when stored energy could be better used elsewhere.
This may help reduce reliance on grid electricity, particularly during higher-cost periods, depending on your electricity plan, vehicle and system configuration.
Additional Energy Resilience
One of the most interesting possibilities of V2H technology is backup energy.
With a compatible EV and correctly configured home energy system, energy stored in your vehicle may be available to support selected household loads during a grid outage.
Backup capability should always be assessed for the specific EV, inverter, charger and electrical configuration, as compatibility and available functionality can vary.
Intelligent Energy Management
The SolaX Binary Series is designed to work as part of a smarter energy ecosystem.
Rather than treating your solar panels, EV and battery as completely separate technologies, an integrated system can coordinate how energy is generated, stored and used throughout your home.
Your EV + Solar: A Smarter Combination
Imagine a typical sunny day.
During the Day
Your rooftop solar generates electricity for your home.
When there is surplus solar available, compatible energy management equipment can prioritise charging your EV instead of relying entirely on grid electricity.
In the Evening
Solar production falls while household electricity consumption often increases.
Depending on your vehicle, tariff, system settings and V2H configuration, stored energy from your EV may help support household consumption rather than drawing as much electricity from the grid.
Overnight
Your charging schedule can also be configured around your household's needs and electricity tariff.
Where appropriate, charging during lower-cost periods can help ensure your vehicle is ready for the next day while allowing your home energy system to operate more efficiently.
Manage Your Energy with SolaXCloud
When integrated with compatible SolaX equipment, the SolaXCloud platform gives homeowners greater visibility and control over their energy system.
Depending on the installed equipment and configuration, homeowners can monitor energy generation and consumption, review historical system performance, manage charging schedules and use available operating modes to better match EV charging with their household energy needs.
For example, surplus solar can be prioritised for EV charging when available, while faster charging options can be used when getting the vehicle ready quickly is more important.
Do You Still Need a Home Battery?
This is where things get interesting.
An EV can have a much larger battery than many dedicated residential battery systems.
With V2H technology, some of that stored energy may potentially support your home.
But that doesn't necessarily mean an EV replaces a home battery.
A dedicated solar battery is designed around everyday household energy storage and is normally available at home whenever required. Your EV, on the other hand, may be away from home when energy is needed.
For some households, the smartest solution may be a combination of solar + home battery + bidirectional EV charging.
The right setup depends on your electricity usage, driving habits, solar production, EV compatibility, budget and backup requirements.
Is Your EV Compatible with Bidirectional Charging?
This is one of the most important questions to ask before installing a V2H system.
Not every EV currently supports the functionality required for bidirectional home energy use, and compatibility can depend on the specific vehicle model as well as the inverter, charger and electrical configuration.
Before choosing a system, DSW Energy can help assess your existing solar equipment, EV compatibility, household energy consumption and future energy requirements.
That way, your system is designed around what your home actually needs rather than simply adding another piece of technology.
The Future of Home Energy Is Connected
Australian homes are becoming more than electricity consumers.
With rooftop solar, battery storage, smart energy management and electric vehicles, households can increasingly generate, store and manage their own energy.
Bidirectional EV charging represents another step in that transition.
Instead of thinking about your solar system, battery and electric vehicle separately, they can become parts of one connected home energy ecosystem.
The potential benefits include:
Greater use of your own solar energy
Reduced reliance on grid electricity
Smarter EV charging
Better management of peak electricity periods
Greater household energy resilience
More flexibility as your energy needs change
