BYD has added the Sealion 7 to its partnership with Amber’s vehicle-to-grid program (V2G), which allows owners to use their cars to power their home or electricity from the battery to the grid to earn a bit of money on the side. 

The SUV joins the brand’s Atto 3, which is already part of the collaboration – and Aussies who participate in the program can get a six per cent discount when they buy the vehicles, too.

V2G or bidirectional technology allows EV owners to take advantage of cheap or free solar electricity during the day, then use it to run their home power or sell it back to the grid at peak times, when power prices are at their highest. Amber’s system, which requires a compatible bidirectional charger, powers up the vehicle with low-cost juice, then allows it to be fed to the home or exported.

Amber claims using the system can save motorists approximately $2500 a year, with that figure based on 2025 wholesale electricity pricing data. While the charger costs $2990, that is offset by the discount on the BYD models, which saves $2519 on the Atto 3 EVO Dynamic, $2819 on the Atto 3 EVO Premium, $3179 on the Sealion 7 Premium, and $3839 on the Sealion 7 Performance variant.

There are no worries about any effect on battery warranty, either, with Amber program participants retaining full support. However, that may not apply for owners who use other V2G systems.

“The Atto 3’s involvement has shown us the value this can unlock for customers, and as strong supporters of the technology, we’re proud that we can broaden the partnership with Amber,” said BYD chief product officer Sajid Hassan.

Amber currently has 50 V2G sites and plans to grow to cover 1000 Aussie households due to good demand, as evidenced by the 8000-strong waiting list. WhichCar by Wheels noted that the Amber stand was one of the busiest at Sydney’s Everything Electric show on Friday, with all seats taken for the regular talks staff were giving to explain how the system works.  

The company’s V2G program has received a total of $126.2 million in federal government funding through the Australian Renewable Energy Agency. Working with EV makers like BYD is a great fit as the batteries in many cars are able to store far more power than home units such as Tesla’s Powerwall.
