Keep your lights on when the grid goes down, and store your own power for when you need it. We install home batteries (Tesla Powerwall, Enphase, FranklinWH, and more) with licensed electricians, one in-house crew, every permit pulled, and every job signed off by our master electrician.
No obligation. We'll reach out within 24 hours.
A home battery stores electricity (from the grid, from your solar panels, or both) and releases it when you need it. When the grid goes down, it automatically keeps your essential circuits running: fridge, heat, lights, medical equipment, internet. No generator, no gas, no noise.
Installing one is more than mounting a box on the wall. It ties into your electrical panel through a transfer switch or backup gateway, needs correctly-sized wiring and overcurrent protection, and must be configured to power the right circuits safely, which is why it's core electrical work, not a plug-and-play appliance: done wrong, it can backfeed the grid and endanger utility crews.
At Heliotek, battery storage is core electrical work. We're licensed electricians first. We size the system to what you actually want to back up, integrate it with your panel (and your solar, if you have it), and commission it to run safely for years.
Every system is quoted up front: licensed, permitted, master-electrician-approved work across New England. No lowball bait, no hidden fees.
Every home is different. What moves the price: how much you want to back up, the number of batteries, your battery and gateway hardware, whether it integrates with existing or new solar, your panel's condition, and municipal permit fees ($100–$500). Your written quote includes everything: materials, labor, permits, and inspection. You're paying for licensed electricians, one in-house crew with no subcontractors, and a job that's permitted, inspected, and signed off by our master electrician.
Most battery quotes come from a solar-panel sales outfit that subcontracts the wiring. Here's what a licensed electrical contractor does differently.
Every battery install is done by licensed electricians and signed off by our master electrician. A battery is a high-current device wired straight into your service: done by an unlicensed installer, it can backfeed the grid, void your warranty, and put your home at risk. We do it to code, every time.
No subcontractors, no handoffs. If your panel needs work to integrate the battery, the same crew handles it: one permit, one team, one visit. We can add or upgrade solar at the same time, too.
We size your system for what you want to back up today and where you're headed. Adding solar, a second battery, or an EV charger later? We'll plan the capacity now so you're not paying to redo it.
We visit your home, review your panel and any existing solar, and talk through what you want to back up. You get a clear scope and a written quote.
You receive a detailed, line-item quote: the battery system plus any panel or solar work, permits, and inspection all included. No hidden fees, no surprise change orders.
We pull all permits, file the utility interconnection paperwork, and schedule the work at a time that suits you. You don't have to make a single phone call.
Our licensed crew mounts the battery and gateway, wires them into your panel, and commissions the system (testing that backup kicks in when the grid drops), and leaves your home clean.
We schedule the municipal inspection, confirm the utility sign-off, hand you all documentation, and show you how to monitor and get the most from your system.
