"Customers can now also make their investment in solar work harder, as excess electricity produced during the day can be stored for use at a later time when the solar panels do not produce electricity." Tesla is already a global leader in battery storage and with 400,000 of Origin's 4.3 million customers using solar energy solutions, it seems Tesla's reach will extend even further. Origin is bundling the Tesla Powerwall with Trina solar panels and the Solar Edge inverter as part of a home energy solution. The Solar Edge inverter uses solar optimisers on each panel to deliver improved system performance and has been approved by Tesla Energy for pairing with the Powerwall. The Powerwall is a wall-mounted rechargeable lithium ion battery that can power your entire house. The release of the Powerwall is expected to see a spike in the number of Australian households switching to solar.
