Battery Storage for the East End
Tesla Powerwall and premium battery systems engineered for storm resilience and complete energy independence.
Battery Storage for the East End — Beyond Backup
When nor'easters hit the East End, the difference between a comfortable home and a powerless estate is battery storage. We design Tesla Powerwall, Enphase IQ, and premium battery systems that provide whole-home backup, grid independence, and seamless solar integration.
Whole-Home Backup, Not Just Lights
Our battery designs power your entire estate during outages — HVAC, refrigeration, well pumps, security systems, and lighting. No more guessing which circuits matter most. Configure your whole-home system to maintain normal life during storms.
Seamless Solar Integration
Battery systems work hardest when paired with solar. We integrate Tesla Powerwall and Enphase IQ Battery systems directly with your solar array for true energy independence — using your panels by day, your battery by night, the grid only when you choose to.
Built for East End Storms
The East End experiences power outages from hurricanes, nor'easters, and grid instability more often than most regions. Every battery system we install includes weatherized installation, surge protection, and remote monitoring — engineered for the specific demands of coastal Long Island.

How It Works
Our Process
Load Analysis
We audit your home's electrical loads to determine the right battery capacity for your backup needs — from critical circuits only to whole-home coverage.
System Selection & Design
We recommend the optimal battery platform for your property and produce a complete system design, including housing, electrical routing, and integration with your solar array.
Installation & Commissioning
Our licensed electricians complete the installation and commission the system with full utility interconnection and permitting handled in-house.
Monitoring & Support
Remote monitoring, firmware updates, and priority support are provided for the life of your system through our ongoing service program.
Pairs Well With
Residential Solar
Battery storage performs best when paired with a solar system. If you don't yet have solar, we design both together as a single integrated solution.
Explore Residential Solar →Off-Grid Systems
For Shelter Island and other properties where true grid independence is the goal, off-grid solar and battery design offers complete autonomy.

"We lost power for three days after a hurricane two years ago. This winter, the same storm came through and we didn't notice. The system ran the whole house without interruption. That is what we paid for, and that is what we received."
