Lion Sanctuary™

Residential Smart Energy Storage System

Lithium-based home battery backup systems.

Lion Sanctuary

Prepare for the next power outage with the safest, quietest backup power generator.

The Lion Energy Sanctuary system stores 13.5kWh of backup power to automatically keep your house running during those unexpected power outages.

Avoid noisy, fuel-powered generators that require upkeep and maintenance. The Sanctuary uses lithium iron phosphate battery cells to give you immediate power that is safe, silent, and renewable. No maintenance is required.

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. The Sanctuary uses advanced technology as part of our LionESS (Energy Storage System).

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.

With the Inflation Reduction Act, residential batteries installed in 2023 can qualify* for the 30% federal tax credit, even if they aren’t attached to solar panels. This may allow you to save thousands and is a key to unlocking affordable, clean energy.

*To qualify, the taxpayer must be the owner of the battery system, must have taxable income, and the system must be installed at the taxpayer’s residence. It can only be claimed on the original installation of the system, and the battery must be as least 3 kilowatt-hours (kWh) in size. Other conditions may apply to your personal situation. Please refer to a tax expert in your area. Source: https://www.energy.gov/eere/solar/homeowners-guide-federal-tax-credit-solar-photovoltaics

Lion Sanctuary™

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

CONSTANT STORAGE

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.*

FLEXIBLE OPTIONS

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.*

24/7 AVAILABILITY

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.

Client Case Studies

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.

Backup Options - Pros/Cons

Sanctuary system Gas generator Portable lithium generators

Pros

Expandable
Can be expanded to a larger capacity either at install or later when budget allows.
Higher Capacity
Higher potential energy storage capacity of over 30 kWh (a typical home uses ~30 kWh a day)
Lower Price per kWh
Lower price per kilowatt-hours at larger storage levels
Seamless Transition
In a power outage, power automatically begins to draw from the backup unit.
Higher Lifecycles
Stationary, permanently installed, lithium iron phosphate backups generally have 6,000+ lifecycles compared to ~3,500 lifecycles for portable-based units.
Longer Warranty
10+ years for a stationary unit compared to 3-5 for portables.
Bigger Inverters
Stationary units have bigger, more powerful inverters. This lets you power more items and larger appliances.
Run More Devices
With larger inverters and more capacity, you can run more items and larger appliances for longer.
More Efficient
Only draws the power that is needed.
Inside Installation
Some lithium iron phosphate systems, like the Sanctuary, are safe to install indoors.
Fed Tax Credit
May qualify for up to a 30% tax credit based on the Inflation Reduction Act.
HELOC Financing
As a permanent addition to your home, this purchase qualifies as an appropriate home equity loan purchase.
Renewable Sources
Can be recharged through renewable energy sources such as solar and wind.
Silent and Safe
No moving parts create a quient experience. And with no fumes or emissions, there is no danger to your health.
Home Resale Value
May increase the resale value of your home.
Traditional Concept
A traditional, cumbustible engine. The style used for the past 20 years for home energy backup.
Portable
Can be removed from the home setup and taken as a portable unit.
Second Location
As a removable unit, you can reattach to a setup in a different house.

Cons

Smaller Capacity
Cannot expand beyond ~22 kWh of total capacity.
Smaller Inverter
Due to limited capacity, you have to run less items for less time.
Shorter Lifecycles
Portable units have ~3,5000 lifecycles compared to 6,000+ for stationary units.
Shorter Warranty
2-5 year warranty.
Dated Technology
Combustible engines are dated technology compared to battery-based systems.
Loud Engine
Combustible engines, regardless of their build, create noise.
Ongoing Cost
Ongoing purchase of fuel and maintenance.
Not Exapandable
Once you purchase your unit, that's all you get. To increase capacity, you must replace the entire unit.
Outside Installation
Must be installed outside to due fumes, emissions, or volatile chemistry.
Not Renewable
Cannot be recharged with renewable energy resources like solar and wind.
Inefficient
Provides full power output regardless of energy needs.
No Tax Credit
Does not qualify for a tax credit.
Additional Hardware
Requires additional hardware to be purchased to install system.
Manual Transition
Must be manually started on event of a power outage.
Phantom Power Loss
Due to additional features that are "always on". Power is constantly leaked to keep these features running.
Installation Required
Professional installation required.
Permits Required
State and/or local permits may be required for installation.

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.
