Lion Sanctuary™

Residential Smart Energy Storage

Weather the storm

Losing power isn't fun. The average power loss duration in the US is 8 hours and increasing. You don't have to go without power during emergencies. Our essential Lion Sanctuary energy storage solution is a perfect option for 95% of the power outages, keeping your essentials (e.g. fridge, lights, outlets, furnace, and WI-FI) running for the duration.

For residents that live in higher risk areas for hurricane or flood zones, the average power outage duration is roughly 25 hours. We've got you covered with expandable options of the Lion Sanctuary.

Lion Sanctuary™

The perfect system to give you critical energy backup for those unforeseen power emergencies.


Grid, gas generators, panels, wind turbines, all produce energy that is pushed to our incredibly safe lithium iron phosphate battery storage system.

Our expandable and maintenance-free battery storage system holds energy for when and where you need to use it, creating a perfect 24/7 energy backup for your home.*


You decide the size of your backup system. You can be prepared to cover just your essentials for the duration of an outage or power everything in your home for longer.

Proprietary software monitors the level of your energy storage and pulls power from the least expensive source at the best possible time, so you are always efficient with your power usage.*


Use the right amount of power at the right time. Even “fill up” portable energy sources so you can have power remotely.

"Time of use” allows you to reduce the cost of your energy by powering up the Sanctuary during lower-cost times and using it during higher-cost periods.

Be protected 24/7. Have peace of mind.

* Lion Energy does not sell home solar panel systems. To add solar to integrate with your Lion Sanctuary system, please contact a licensed provider in your area.

Smart Energy Storage

The Lion Sanctuary dramatically reduces energy cost when either paired with solar panels or in areas that have peak billing.

Solar panels typically are most efficient during periods of lower demand. Pairing solar panels with the Lion Sanctuary stores energy during the day for use during peak usage time in the evening and early morning.

In areas where energy costs have peak and off-peak billing times, the Sanctuary can be set to collect energy from the grid during off-peak times for use during peak hours, thus mitigating energy costs.


Top-quality technology

Smart Energy Storage is built using our proprietary technology of:

  • Lithium iron phosphate battery storage
  • Cutting-edge inverters
  • US-based engineering that interweaves monitoring software
  • Easy-to-use app technology
  • Ready to use anytime and anywhere

Compared to old tech that required:

  1. Fossil fuels in form of gas or natural propane
  2. Dangerous health-hazardous from fumes and fire issues
  3. Maintenance to ensure your system is ready to use
  4. Scarce availability of resources in an emergency
  5. Negative environmental impact
“The Lion Sanctuary is a perfect solution to integrate a smart energy storage system with our current centralized electrical grid.”
—Tyler Hortin, President of Lion Energy

Get an estimate

Get an estimate of what size of system you might need. Using data like state average power cost and your monthly power bill, we can estimate how much power you use on a monthly basis. We can then determine if you need the “essentials back up” or “whole home back up”.

Through our online estimate process, we can take a complicated process and give you a simple solution or you can chat with an expert.


Advanced Design

With easy installation and a minimalist design, the compact, all-in-one construction features versatile mounting options for being mounted indoors, eliminating the ugly curb appeal issues with a large battery system attached to the outside of your house.

By using lithium iron phosphate, it is possible to install the Lion Sanctuary indoors. Other backup systems often use a lithium NMC design that can be combustible and should be installed on the outside of a structure.

Better capabilities. Better solution.

The Lion Energy Sanctuary is the only lithium-based backup system that comes with installation included (reducing unexpected costs on the back end of the purchase) and comes standard with an inverter while others may only provide the battery. The Sanctuary has better energy capacity, max peak load, and max continuous load than the competition. In all, the Sanctuary gives you the most complete package for your emergency backup at a comparable price.
