The federal government's battery rebate scheme has been a success, with over 105,000 new installations and 2 gigawatt hours of storage in four months. SigEnergy and Amber are emerging as winners in the market, offering lower cost technology and smart controls for consumers. Both companies are focusing on combining solar PV, battery storage, EV charging, and vehicle-to-grid technology to meet consumer needs. The growth in battery storage through federal rebate schemes is exceeding expectations, with around one in five rebate recipients signing up for retail offerings like Amber's. Plans are in place for V2G technology to become more widespread by 2030, potentially leading to many households becoming grid independent.
