Energy Storage for a Sustainable Home
Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. It also fortifies your home against power outages by providing a backup electricity supply. Automated, compact and simple to install, Powerwall offers independence from the utility grid and the security of an emergency backup.
MORNING DEMAND
PEAKSOLAR
EVENING DEMAND
Solar Powered Day and Night
The average home uses more electricity in the morning and evening than during the day when solar energy is plentiful. Without a home battery, excess solar energy is often sold to the power company and purchased back in the evening. This mismatch adds demand on power plants and increases carbon emissions. Powerwall bridges this gap between renewable energy supply and demand by making your home’s solar energy available to you when you need it.
Avoid Paying Peak RatesPower companies often charge a higher price for electricity during peak evening hours than overnight when demand is low. Powerwall can store electricity when rates are low and power your home when rates are high.
Energy SecurityPowerwall automatically switches to battery power in the event of an electric company outage, bringing peace of mind to those who live in areas prone to storms or unreliable utility grids.
Beautifully Functional
Current generation home batteries are bulky, expensive to install and expensive to maintain. In contrast, Powerwall’s lithium ion battery inherits Tesla’s proven automotive battery technology to power your home safely and economically. Completely automated, it installs easily and requires no maintenance.
Capacity
Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries may be installed together for homes with greater energy need, up to 90 kWh total for the 10 kWh battery and 63 kWh total for the 7 kWh battery.

How it Works
Home solar installations consist of a solar panel, an electrical inverter, and now a home battery to store surplus solar energy for later use.
- Solar panelInstalled in an array on your roof, solar panels convert sunlight into electricity.
- Home batteryPowerwall stores surplus electricity generated from solar panels during the day or from the utility grid when rates are low.
- InverterConverts direct current electricity from solar panels or a home battery into the alternating current used by your home’s lights, appliances and devices.
Contained within Powerwall's outdoor-rated enclosure is a rechargeable lithium-ion battery, a liquid thermal management system, a battery management system and a smart DC-DC converter for controlling power flow.
