Wallbox Quasar 2 V2H Installation — Southern Perth
The Wallbox Quasar 2 is the only commercially available vehicle-to-home (V2H) charger in Australia as of 2026. It does something no other charger currently can: it lets your electric vehicle power your home. During a blackout, or when grid tariffs are high, the Quasar 2 draws energy from your EV's battery and supplies it to your home — effectively turning your car into a giant home battery. Currently, V2H operation via the Quasar 2 is only compatible with the Kia EV9 in the Australian market. Other vehicles are in trial programs but not yet commercially supported. If you drive a Kia EV9 and want to explore V2H, the Quasar 2 is the only path available today. This is an emerging, forward-looking product — and an early-mover opportunity for EV9 owners in Perth who want home backup power without purchasing a separate battery system.

V2H is only commercially supported in Australia with the Kia EV9 + Wallbox Quasar 2 combination as of 2026. Tesla V2H is not officially enabled in Australia. AGL's V2G trial includes Hyundai, Kia, BYD, and Zeekr vehicles, but this is a trial, not a commercial product available to all customers. We install Quasar 2 for Kia EV9 owners — contact us to discuss your specific situation.
Common Questions
Can I use the Wallbox Quasar 2 with my Tesla?
No. Tesla V2H is not officially enabled in Australia as of 2026. The Quasar 2 currently supports V2H operation with the Kia EV9 in the Australian market. We expect V2H compatibility to expand over the coming years as the technology matures.
How much of my house can the Quasar 2 power during a blackout?
At 7.4 kW discharge capacity, the Quasar 2 can power most household essentials — lighting, fridge, WiFi, TV, phone charging, and even a split-system air conditioner. High-draw appliances like electric ovens and large heat pumps may exceed capacity. The Kia EV9's 88.1 kWh battery could theoretically power a typical Perth home for several days.
Is this the same as the AGL V2G trial?
No. The AGL V2G trial is a separate program where AGL manages when your EV charges and discharges to stabilise the grid. The Wallbox Quasar 2 + Kia EV9 setup is a commercial product you can install independently, without being enrolled in a specific energy retail trial. Both are examples of bidirectional charging, but they're different solutions.
What does V2H installation cost?
More than a standard EV charger install, due to the bidirectional circuitry, Western Power notification, and metering requirements. See our vehicle-to-home cost guide for current price ranges.
