A revolutionary battery for home
Powerwall is a home battery that stores solar energy so you can use it day or night and self-power your home. Giving you the ability to own your energy and reduce your reliance on the grid. Solar generates clean energy and typically more than your house can immediately use. Powerwall stores that excess solar energy allowing you to make solar available on demand. Through the Tesla mobile app, you will have full visibility and control over your self-powered home.
Measuring only 1150 x 755 x 155mm it is a sleek, compact unit which can be mounted on an external wall or indoors as necessary. It is a completely automated system that requires no maintenance once installed. Liquid thermal controls and touch safe technology maximise battery life and safety. With an integrated battery inverter, Powerwall is the most affordable home battery in terms of cost per kWh.

Powerwall provides a number of benefits
Increasing self-consumption of solar power generation –Powerwall can store surplus solar energy during daylight hours and use that energy later when the sun is not shining.
Load shifting – Powerwall can charge during low rate periods when demand for electricity is lower and discharge during more expensive rate periods when electricity demand is higher.
Back-up power – Assures power in the event of a grid outage.
