Lion Energy Sanctuary 2 – Home Energy Storage System The Lion Energy Sanctuary 2 is a powerful, fully automated home energy storage system designed to keep your home running during power outages. Built with advanced LiFePO₄ battery technology and a hybrid grid-support inverter, it delivers reliable, quiet, and maintenance-free backup power. When the grid goes down, the system instantly switches to battery power — keeping your lights, refrigerator, furnace, Wi-Fi, and essential appliances running without noise, fuel, or manual intervention. Designed for indoor installation, the Sanctuary 2 is ideal for whole-home or essential-load backup and can be expanded as your energy needs grow. Key Features Automatic Backup PowerInstant seamless transition to battery power during outages — no fuel, no noise, no manual transfer switch required.
