More storage. More savings.
The Tesla Powerwall 2 is a rechargeable battery system and an energy storage device. It has double the storage capacity of the original Powerwall. It’s front-line solar battery technology that means you can make the most of your solar system. So you get even more opportunity for electricity bill savings.
When Self-Powered mode is selected, your Powerwall stores solar energy not used during the day to power your home at night. Your Powerwall will charge when excess solar power is produced, and this stored energy will be used when your home requires more power than your solar system can provide.
