Power through Uncertainty

Keep the lights on, protect your family and secure your home office during blackouts. Our 100-year-old utility grid is expensive, dirty, and susceptible to extreme weather. As blackouts become the new normal, Battery Storage backs you up with reliable, clean energy for your home and family.

Self -Powered

While your solar energy system produces energy, the excess amount is automatically stored in your home battery for the times you need it most and/or is sold back to the grid for future utility bill credits.

Back-up Power

When power outages and blackouts occur, your home battery will disconnect you from the grid and automatically restore power to your home. Most homeowners never even notice the power went out.

Energy Independence

Become energy independent and power your home 24 hours a day. Your home battery will store the unused electricity your solar panels produce so it's available when you need it most.

HOW SOLAR BATTERY STORAGE WORKS

During the day, your solar panels produce electricity to power your home and charge your battery storage. At night or during cloudy days when your solar panel system isn’t producing enough energy, your battery will detect this and decrease the electricity you draw from the grid by utilizing the energy it previously stored. Not only does it reduce your reliance on the grid, but it also continues to keep your utility bills low. Plus, when blackouts and outages occur, your battery storage will kick in to keep your lights on, your phones charged and your appliances running smoothly.

Why Long Island Homeowners Need Battery Storage

Our 100-year-old utility grid is expensive, vulnerable to extreme weather, and blackouts are becoming the new normal. During an outage, your battery disconnects you from the grid and restores power automatically -most homeowners never even notice the lights flickered. By day, excess solar energy charges your battery instead of being wasted; by night, that stored energy powers your home, so you buy less from the utility.

How Solar Battery Storage Works

During the day, your solar panels power your home and charge the battery. At night or on cloudy days, the battery supplies that stored energy instead of the grid — keeping bills low around the clock. When an outage hits, the system detects it instantly, disconnects from the grid, and automatically restores power to your lights, phones and appliances. Excess production is either stored for later or exported to the grid for bill credits under PSEG Long Island’s net metering program.
