BioLite is launching a modular battery system called Backup by BioLite, designed to provide emergency power to refrigerators during outages. The system offers a more affordable alternative to whole-house battery backup systems like Tesla Powerwall, which can cost up to $15,000 after installation.

The Backup by BioLite system is designed specifically with the fridge in mind, providing long-term emergency power at a fraction of the cost of more complex systems. The massive battery offers 1526 watt-hours of power with a rated output of 1800 watts, and can be installed by homeowners themselves in just 30 minutes.

The power pack measures 29 inches high by 13 inches wide and weighs 40 pounds, making it a compact solution for emergency power needs. The Backup Extend add-on device can be used to double the power capacity to 3072 Wh, and additional devices can be added in series to increase the total maximum capacity to 10.5 KWh.

The full 'Backup Complete' solution, with two cells, can provide up to 60 hours of running time if the grid goes down, giving homeowners peace of mind and protecting their food from spoilage. This is especially important during power outages, when the loss of refrigeration can result in significant food waste and financial loss.

## Why it matters The Backup by BioLite system addresses a significant problem for homeowners, who often face significant financial losses due to food spoilage during power outages. With the rising cost of living and increasing frequency of power outages, a reliable and affordable emergency power solution is more important than ever. The Backup by BioLite system offers a cost-effective alternative to whole-house battery backup systems, making it an attractive option for homeowners who want to protect their food and their finances.

## What happens next As the Backup by BioLite system becomes available, homeowners will have a new option for emergency power that is both affordable and reliable. With its modular design and easy installation, the system is expected to be a popular choice for those looking to protect their food and their finances during power outages.
