EV Charger & Tesla Powerwall Installation in Sag Harbor, NY
Sag Harbor is one of the few Hamptons communities that thrives year-round — and its homeowners expect contractors who match that standard. Homefront Energy is a Tesla Certified, veteran-owned electrical contractor serving Sag Harbor, North Haven, and the surrounding East End with EV charger installation, Tesla Powerwall battery systems, and panel upgrades.
We've completed 600+ installations across Long Island and are fully experienced with the Village of Sag Harbor permitting process from start to finish.
Our Services in Sag Harbor
Tesla Powerwall Installation
Power outages in the Hamptons aren't just inconvenient — on a large estate, they affect HVAC, security, well pumps, outdoor lighting, and refrigeration. Tesla Powerwall 3 keeps your home fully operational through any outage, silently and without fuel. We are a Tesla Certified Energy Installer and handle the full installation including utility interconnection and town permitting.
EV Charger Installation
Level 2 EV charger installation for all vehicles — Tesla, Rivian, Porsche, BMW, Mercedes, Range Rover, Audi, and more. We design multi-vehicle charging setups for garages with 2, 3, or 4 EVs, with proper load management and dedicated circuits. Tesla Certified and Qmerit-certified.
Panel Upgrades
Sag Harbor estates often run into capacity limits when adding EV chargers, Powerwalls, and modern electrical loads to older electrical services. We perform 200A–400A panel upgrades and subpanel additions sized for today's high-demand homes.
Bi-Directional Charging (V2H)
We install Tesla Powershare, Ford Intelligent Backup Power, and GM Powershift systems — vehicle-to-home technology that turns your EV into a backup power source for your entire home. Ideal for Hamptons properties where backup power is a priority. One of the few installers on Long Island certified and experienced in vehicle-to-home technology.
Solar Wiring & Interconnection
We provide all electrical wiring for solar installations on Sag Harbor and Hamptons properties, including interconnection, panel coordination, and bi-directional charging setup.
Seasonal & Second Home Scheduling
We understand Hamptons properties are often seasonal or part-time residences. We work around your schedule — whether you need installation completed before summer, or coordinated during a specific visit window.

Storm Preparedness Is What We Do
Our Master Electrician is a former Fire Chief. Storm-ready electrical systems aren't a marketing angle for us, they're how we think about every installation. A Powerwall-equipped Sag Harbor home stays operational when the grid goes down.
