Down East · Hancock County · Coastal Maine
Ellsworth Unlimited engineers and installs power, connectivity, and automation systems built for the realities of the Maine coast: no grid at the property line, salt air on every connector, and winters that punish anything half-done. We spec it, we wire it, we stand behind it.
What we build
Every one of these is chosen because a Maine property demands it — not because it looks good in a brochure. We design the whole system, source the hardware, and do the install.
Islands, camps, and Down East properties that sit a half-mile past the last utility pole. Solar arrays, lithium storage, and inverter systems sized for short winter days — with generator auto-start for the deep cold.
Remote & island powerStarlink and fixed-wireless brought inside, then meshed across barns, boathouses, and acreage where a single router never reaches. Failover between links so a seasonal home stays online year-round.
ConnectivitySmart controls for heat pumps and boilers, remote thermostats, and freeze & water-leak sensors that alert you before a burst pipe empties a camp you won't visit until May.
Climate automationDock power and lighting, shore-power management, boathouse camera systems, and hardware specced for salt, spray, and tide — the working edge of the Maine coast.
WaterfrontCamera, entry, and monitoring systems built for houses that sit empty for months. Cellular-backed so they keep watching even when the power and internet go down in a nor'easter.
MonitoringAutomatic standby generators and battery backup, transfer switches, and load management so the well pump, heat, and freezer never quit during a multi-day outage.
ResilienceMonitored well pumps, pressure and tank-level sensors, and freeze-safe controls — because out here the water system is technology, and it fails at the worst possible time.
UtilitiesHome EV chargers sized to rural service, plus structured low-voltage cabling — the clean backbone that ties power, network, and control together in one documented system.
InfrastructureHow we work
You get one team from the first site walk to the final label — not a designer who hands you a parts list and disappears.
We come to the property — the real one, with its dead spots, its old wiring, and its half-mile driveway — and map what's actually there.
A documented design: what hardware, sized to your loads and your winters, with the trade-offs spelled out in plain language before a dollar is spent.
We source and install it — power, network, controls, and enclosures — done to hold up to salt air and cold, and labeled so the next person understands it.
Documentation, a walkthrough, and someone local to call. Remote-monitored systems mean we often see the problem before you do.
Service area
Based in Ellsworth, Maine, Ellsworth Unlimited serves Hancock County and the surrounding coast — from the Blue Hill peninsula and Mount Desert Island to the camps and islands scattered along the Down East shoreline.
Property off the beaten path? That's exactly the kind of job we're built for.

Off-grid build, a connectivity headache, or a system that needs to survive the winter — send the details and we'll map out an approach.
