I am very keen for batteries. We have 20'ish kw of solar and so much is wasted because of export limits. If I could pump all that waste in to a battery to use over the peak period of an afternoon/evening we'd greatly reduce our bills.

Grab a new V2H/V2G charger as they start to come out and add it to an ecar.

The batteries on ecars are massive in conparison to home battieries.

Got an EV too - 85kw'ish of battery ready to roll.

Would love to soak it up over peak period, then recharge it overnight at off peak rates. Doing that alone would be a big saving.

Was interested in this one as

Through a partnership agreement with ambibox, RedEarth will produce the devices from its facility at Darra in Brisbane’s south-west suburbs – the first company to manufacture (assemble?) bi-directional chargers locally.

But have to see how it compares

The Ambibox DC Wallbox is a flexible bidirectional charger supporting both V2G and V2H applications. It offers up to 22kW of charging power. It has even been used in experimental setups to enable bidirectional charging in vehicles not originally designed for it—such as the Tesla Model Y. It’s ideal for both residential and commercial use.

The Ambibox unit has been able to successfully discharge energy from several EV models during testing:

Tesla Model Y BYD Atto 3 Polestar 2 Volvo EX30

Interesting!

I wonder if this will also include extra subsidies for electric vehicles which support bidirectional charging. Could really help push for an increase in electric vehicle uptake if you can also use it as a battery overnight.
