# Backup Box

## Products:



### Energy security, even during grid outages

A reliable power supply is essential, especially for applications where continuity is key. With a **backup box**, a PV installation automatically switches to backup power when the grid fails. This solution is indispensable when combined with a **[home battery](/assortment/energy-storage/home-battery)** or **[commercial battery](/assortment/energy-storage/commercial-battery)** and is increasingly used in both residential and commercial environments.

### How does a backup box work?

The backup box acts as an automatic switching unit. In the event of a power outage:

- The installation is disconnected from the grid
- It immediately switches to stored energy from the battery
- The selected circuit(s) or entire installation continue to operate

Depending on the type of backup box and battery system, users can maintain access to lighting, Wi-Fi, medical equipment, or even ensure full business continuity during a grid failure.
