Your Next Generation Energy Storage Solution

Lion Sanctuary - Reliable, Quiet, and Zero-Maintenance Backup Power

Be ready for anything with the Lion Sanctuary™—your dependable, long-lasting home power solution. Powered by advanced lithium iron phosphate batteries, it’s maintenance-free and runs quietly, without the fumes or noise of traditional generators.

Stay powered no matter what. When the grid fails, your Sanctuary delivers immediate, uninterrupted backup. It powers your essentials like refrigeration, lights, furnace, Wi‑Fi, and outlets for most outage scenarios with ease. Whether you're in a hurricane zone or dealing with seasonal power loss, the Sanctuary’s scalable design ensures you stay online.

The Lion Sanctuary Home Backup System detects outages from the grid to keep your life running.

The Lion Energy Sanctuary system stores 14.3kWh of backup power to automatically keep your house running when solar isn’t available

Watch your system's performance, control battery settings from your mobile, and save by optimizing energy use with real-time insights and consumption tracking..

Power Outages Happen. Be Ready.

The average U.S. power outage lasts about 8 hours and that number is rising. The Lion Sanctuary™ keeps your essentials—fridge, lights, furnace, outlets, and Wi-Fi—running for most outages.

Powered by our advanced LionESS™ technology, it delivers reliable, maintenance-free backup you can trust.

For homes in hurricane or flood zones, where outages average around 25 hours, the Sanctuary offers expandable capacity to keep you powered even longer.
