With the Powerwall 3’s intelligent energy management system, he can program the system to charge during off-peak hours when electricity tariffs are lower and discharge during peak hours when rates are higher, maximising his savings without sacrificing comfort or convenience.

The Powerwall 3’s intelligent energy management system can increase self-consumption of solar energy by up to 80%, resulting in significant cost savings (Source: Tesla).

Backup Power Capability

In the event of a grid outage, the Powerwall 3 seamlessly switches to backup power mode, providing uninterrupted electricity supply to essential appliances and devices in your home.

Example: During a severe storm that knocks out power in their neighbourhood, the Johnsons are grateful for their Powerwall 3 system. While their neighbours are left in the dark, they continue to enjoy uninterrupted electricity supply, powering essential appliances like lights, refrigerators, and medical devices until the grid is restored.

Remote Monitoring and Control

With the Tesla mobile app, homeowners can monitor and control their Powerwall 3 system remotely from anywhere in the world.

Example: Emily is on vacation abroad but wants to keep an eye on her home’s energy usage. Using the Tesla mobile app, she can remotely monitor her Powerwall 3 system, check battery status, and adjust settings as needed, giving her peace of mind and control over her energy system from anywhere in the world.

Compatibility with Solar PV Systems

The Powerwall 3 is designed to work seamlessly with solar PV systems, allowing homeowners to maximise their solar energy self-consumption and reduce their reliance on grid electricity.

Example: David recently installed a solar PV system on his roof to reduce his carbon footprint and lower his electricity bills. The Powerwall 3 seamlessly integrates with his solar panels, allowing him to store excess solar energy for use during the evening or on cloudy days, maximising his self-consumption and reducing his reliance on grid electricity.

Longevity and Durability

Built to withstand the rigours of daily use and adverse weather conditions, the Powerwall 3 is engineered for longevity and durability.

The Powerwall 3 is backed by a 10-year warranty, ensuring peace of mind and reliability for homeowners (Source: Tesla).
