We believe all homes should have access to the abundant renewable energy on the grid. The Windfall Battery is a plug-and-play home battery designed for people in flats and smaller homes. It needs no complicated installation or changes to the home, so it can also be used if you’re renting. And if you move home, you can just unplug it and take it with you. It works by charging up with cheap off-peak energy, and then during the peak times it puts that energy back into your home to power whatever you’re using at the time.
