How Home Batteries Work

Through a clever combination of chemistry and electronics, home batteries store excess energy generated by your solar panel system during the day, allowing you to tap into it when the sun goes down.

This process guarantees a continuous supply of power, even during nighttime or periods of low sunlight. As you generate more energy than you consume, the excess is directed to the home battery, where it's stored for later use.

The battery's advanced management system monitors its state of charge, voltage, and temperature to optimize energy efficiency and extend its lifecycle.

When the sun sets or energy demand increases, the stored energy is released, providing a reliable and efficient power supply.
