When Tropical Storm Irene reached Vermont in August 2011, the damage wasn’t what most people picture from a tropical system. It was the water. Rivers and mountain streams jumped their banks, tore out roads and covered bridges, and left towns from the Green Mountains to the southern valleys physically cut off — no way in for repair crews, no way out for residents, and the power gone for days. That’s the Vermont version of a grid emergency: not just downed lines, but downed lines you can’t reach. If you’re comparing Vermont solar quotes, it’s worth knowing a grid-tied rooftop system shuts off in that outage too, unless you also have storage.
When getting to the problem is the problem
Vermont’s terrain is what makes its outages long. Green Mountain Power and the state’s smaller co-ops and municipal utilities serve a lot of homes at the ends of rural roads, and when ice, wet snow, or Irene-style flooding takes out both the line and the road to it, restoration slows to a crawl. A December 2008 ice storm proved the same point in winter. And because an anti-islanding grid-tied array switches itself off the instant the utility line goes dead, the solar panels on your roof won’t help while you wait — only a battery you own will.
The outages Vermont actually gets
Vermont sits inside the ISO New England grid and shares the region’s structural problem: heavily forested rural distribution lines. A wind or ice event does not knock out one feeder, it brings trees onto wires across a wide area at once.
The January 1998 ice storm. Freezing rain coated northern Vermont and left rural customers without power for days, and in places well over a week. It is still the benchmark event.
Tropical Storm Irene, August 2011. Irene destroyed roads and bridges across the state and cut off whole towns, so the outage and the inability of a crew to reach you arrived together. That combination is what makes Vermont outages long.
December wind and wet-snow events. Heavy wet snow loads limbs until they come down on the wires, and it happens most Decembers somewhere in the state.
Deep cold. A cold snap does not cause the outage, it decides what the outage costs you. With no blower and no circulator, an unheated Vermont house loses ground fast.
Terrain is the aggravating factor. Valley roads wash out or block, and a mountain road closure delays restoration far longer than the line repair itself takes. Green Mountain Power, Vermont Electric Co-op, and Burlington Electric Department all work substations and the biggest circuits first, so a house up a dirt road is last twice over: once for being remote, once for being hard to reach. Our New Hampshire guide and Maine guide describe the same pattern next door.
What it takes to keep a Vermont home running
You’re covering essentials, not the whole house. A fridge draws about 150W, a furnace or pellet-stove blower roughly 100 to 200W, ten LED bulbs near 50W, plus the router and phones — under 500W of steady load to keep heat, food, and communication going. A HomePower 3000 handles that for one to two days and comes with foldable solar panels, so on the bright days that often follow a Vermont storm it recharges itself while the road crews are still working.

How long each Jackery runs a Vermont home’s essentials
Size against watt-hours per day, not the wattage on the label.
| Load | Typical draw | Energy per day |
|---|---|---|
| Fridge | ~150W running (cycling) | 1,000 to 1,500Wh |
| Chest freezer | cycling compressor | 600 to 900Wh |
| Gas or oil furnace blower and ignition, or a boiler circulator | 400 to 600W while running | 3,000 to 5,000Wh in deep cold |
| Well pump (240V) | ~1,000W running, 2 to 3x to start | Depends on household use |
| Wi-Fi router | ~10W | ~240Wh |
| LED lights (ten bulbs) | ~50W | ~300Wh (6 hrs) |
| Phones and a laptop | 20 to 60W | 150 to 300Wh |
| CPAP | 30 to 60W | 300 to 500Wh per night |
| Space heater | 1,500W | Not recommended |
Say the last row plainly: a 1,500W space heater drains a 3,000Wh battery in about two hours, so it is the wrong plan. Run the blower or the circulator, which heats the house for a fraction of that energy, and spend the rest of the battery on food, water, and phones.
A mild-weather day lands near 2,000Wh. A January day with the heat running lands nearer 5,000 to 6,000Wh.
HomePower 3000. 3,072Wh and 3,600W covers fridge, freezer, lights, router, and phones for one to two days per charge. Add the furnace blower or circulator in real cold and it is closer to a day per charge. A bright day puts 1,500 to 2,000Wh back through the included panels, a grey winter day only a few hundred. It is 120V only and not expandable.
HomePower 3600 Plus. 3,584Wh, 3,600W, expandable to 21kWh, and transfer-switch ready. That expansion turns a 5,000Wh heating day into three days or more with no useful sun, which is the right shape for a farmhouse at the end of a road that may stay closed. The HomePower 3600 Plus review goes through it in detail.
Solar Generator 5000 Plus. 5,040Wh, 7,200W, 120V and 240V, expandable to 60kWh. The only one of the three that runs a 240V well pump, so if losing power means losing water, this is the unit.

| HomePower 3600 Plus | 3,584Wh · 3,600W · to 21kWh | Days of heat when the road stays closed, on a transfer switch | Check price → |

Tying it into the house
If you’d rather have the essentials come back on their own — furnace blower, fridge, well pump, and lights running off your existing circuits — the HomePower 3600 Plus connects through a transfer switch, holds 3,584Wh at 3,600W, and expands to 21kWh, which suits a Vermont farmhouse that needs backup to run without anyone flipping cords in the dark.

Solar generator vs gas generator in a Vermont winter
- Carbon monoxide and indoor safety. A battery produces zero exhaust and runs in a mudroom or basement with the house sealed against the cold. A gas generator can never run indoors or in an attached garage, so it sits out in the weather and someone has to go to it in the dark.
- Noise. About 30 dB, against an engine you and your neighbors hear all night up a quiet valley.
- Fuel in a storm. The Irene problem exactly. The battery is full beforehand and refills from the sun after. Gasoline runs out, and a washed-out road means no trip to town.
- Cold starting. Push a button at 10 below, or fight a pull cord and cold oil.
- Maintenance. Oil, carburetor, and monthly test runs, against a monthly charge check.
- Running cost. Sun costs nothing. A week of gasoline costs plenty.
- What a gas generator still does better. A very long outage with no sun, and cheap whole-house 240V up front. If that is your farm, pair a gas generator outdoors with a battery indoors for the quiet overnight loads. Our guide to running a furnace on a solar generator covers the heating side.
Set-up checklist before the first storm
- Charge to full now, then top up monthly, October through April.
- Keep it indoors and above freezing. A mudroom, closet, or heated basement, never an unheated barn or garage.
- List the loads it will carry. Furnace or boiler controls, fridge, freezer, router, one lamp per floor. Tape the list to the unit.
- Buy heavy-gauge extension cords for the fridge and the heating runs. Thin cords lose voltage and get warm.
- Test the heat on the battery in October. If the burner is hardwired, have an electrician add a plug-in connection first.
- Keep the panels reachable and clear of snow, with a south-facing spot in mind you can get to without digging.
- Use a licensed electrician for a transfer switch, which the HomePower 3600 Plus is built for, and never backfeed a wall outlet.
- Keep a battery-powered CO alarm regardless. A burner, a wood stove, or a neighbor’s generator can still put carbon monoxide in the house.

Set it up before mud season or the first ice
The lesson of Irene is that help can be days away when the roads go, so the power you’ll have in an outage is the power you set up beforehand. Charge a unit now, learn what it runs, and keep the panels within reach. Look over the current deals first.
