Solar Battery Storage & Backup
Add battery backup to your Florida solar system for energy independence and power during outages. Store excess solar energy for nighttime use and storm-season preparedness.
How It Works
Energy storage needs assessment → battery system sizing based on critical load analysis → equipment selection → professional installation alongside or as an add-on to your solar system → system programming and activation → backup power testing.
Why Battery Storage in Florida
- Standard solar systems must shut down during grid outages for safety reasons
- Battery storage lets you keep critical appliances running during power failures
- Hurricane season (June–November) brings frequent and extended outages across Florida
- Store excess daytime solar production for evening and nighttime use
- Reduce grid dependence even further beyond what solar alone provides
- Battery prices have decreased dramatically — making residential storage increasingly viable
Critical Load Coverage
- Refrigerator and freezer — protect food and medications
- Lighting in essential rooms
- Phone and device charging for communication
- Medical equipment (CPAP machines, oxygen concentrators)
- Wi-Fi routers and security systems
- Sump pumps and water systems
- Custom load prioritization based on your needs
Technology Options
- Lithium-ion battery systems from leading manufacturers
- Scalable capacity — add battery modules as needs grow
- Indoor and outdoor installation options
- Seamless integration with existing or new solar arrays
- Smart energy management — battery charges during peak production, discharges during peak usage
- Mobile app monitoring for battery status and energy flow
Benefits
- Keep your home powered when the grid goes down
- Essential for Florida's hurricane season — peace of mind during storms
- Store excess solar energy for nighttime use instead of sending it to the grid
- Maximize your energy independence beyond net metering
- Protect critical appliances, food, medications, and security systems
- Scalable — add capacity as prices decrease or needs grow
- Smart energy management reduces grid dependence further
Savings Information
- Battery storage maximizes the value of every kilowatt-hour your panels produce
- Evening self-consumption from stored solar reduces grid usage further
- Cost of battery storage continues to decline — improving ROI each year
Florida-Specific Focus
Florida is the #1 state for hurricane exposure. Battery storage provides essential backup power during the June–November hurricane season and the severe thunderstorms common year-round.
Additional Info
- Battery addition may be available as an upgrade to existing solar rental agreements
- Sunlarus is actively developing battery rental options as costs decrease
