The Peace of Mind When The Unexpected Happens
What size of system do you need?

STEP 2
What should stay on?
STEP 3
Do you have solar?
Solar recharges your battery during an outage, so you may need less storage to go the same distance.

STEP 4
How long without the grid?
How long should your system carry you with no grid power?
*This is just an estimate, and you should speak to a Lion Energy Advisor for specific details on your project. Actual needs vary with climate, season, appliance age and how you use your home. Sizing assumes 14.3 kWh per Lion battery, 12 kW continuous output per Sanctuary 3 inverter, and a planning reserve so you aren't running the battery to empty. Solar estimates assume clear-sky production; cloudy or snowy days produce less, so with solar we still size for at least an evening and night of storage. A Lion Certified Installer will confirm the final design for your home.

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.
Case Studies
Heath and Cedar at Red Poppy Ranch were looking for a way to replace an array of 12V batteries for their off-the-grid energy storage. The Lion Sanctuary system more than met their needs.

You May Qualify for Tax Credits
Thanks to the Inflation Reduction Act, residential batteries installed in 2023 may qualify* for a 30% federal tax credit even without being connected to solar. This incentive can save you thousands and makes clean, reliable energy more affordable than ever.
*To qualify, you must own the battery system, have taxable income, and install it at your primary residence. The system must be a first-time installation with a capacity of at least 3 kWh. Additional requirements may apply, so consult a local tax professional. Source: energy.gov
