Our top pick for New Hampshire backup
Jackery HomePower 3000
3,072Wh · 3,600W · solar panels included · LiFePO4 · ~30 dB, zero exhaust
Runs a furnace blower, the fridge, and lights for one to two days of freezing rain, when the same ice that drops the lines keeps crews off the roads. Its panels refill it once the storm clears.
Do you need a generator in New Hampshire? For most homes, yes — and the reason is ice. Ask anyone in the state about losing power and the conversation comes back to December 2008: a slow band of freezing rain glazed the whole state, and the weight of the ice pulled down trees and lines until roughly 400,000 homes went dark — some of them, out in the smaller towns, for a week or more with temperatures well below freezing. It remains the storm the state’s utilities size their crews and their planning against. The good news is that “generator” no longer has to mean a gas engine roaring in the driveway: a solar generator sized to your furnace blower, fridge, and lights covers the outage that actually happens here, runs safely indoors, and never needs refueling on iced-over roads. If you’re comparing New Hampshire solar quotes, the detail installers rarely mention is that a grid-tied rooftop system shuts off in an outage like that unless you also own storage.
Why an ice storm is the worst case here
New Hampshire is served by Eversource, Unitil, and the New Hampshire Electric Cooperative, and the hazard that defines the state isn’t wind so much as ice. Freezing rain loads branches until they snap onto lines, and the same weather that causes the outage makes the roads too dangerous for crews to move quickly — which is why 2008’s restoration stretched out so long around Manchester, Nashua, Concord, and the rural co-op territory. Add that a grid-tied solar array shuts down the moment the line drops, and a house with panels on the roof is no better off in an ice storm than one without.
Sizing backup for a cold-weather outage
The goal isn’t the whole house, it’s staying warm and fed. A refrigerator runs about 150W, the electric blower on a gas or oil furnace roughly 100 to 300W, ten LED bulbs near 50W, plus a router and phone charging — most homes land under 500W of steady draw to keep heat, food, and light going. A HomePower 3000 carries that for one to two days and ships with solar panels that recharge it on the clear, cold days that usually follow an ice storm.
Rural New Hampshire homes lose their water when the power goes, because the well pump stops. A Solar Generator 5000 Plus delivers 5,040Wh and 7,200W with both 120V and 240V and expands to 60kWh — enough to run a 240V well pump, a full heating system, and the rest of a larger home through a long winter outage.
New Hampshire power outage tips: ready before the freezing rain
Ice storms arrive with little warning, and the stores sell out of backup power the moment the forecast turns. A few habits make the difference:
Buy and test in the fall, not when the forecast turns — get the unit charged, run your fridge and furnace blower off it once, and keep the panels where you can reach them.
Top up before the storm: charge the battery from the wall the day freezing rain is forecast, so you start the outage full.
Prioritize heat, food, and phones — furnace blower, fridge, router, and charging come to well under 500W for most homes; skip the electric dryer and oven.
Never run a gas generator indoors or in an attached garage — carbon monoxide kills people in New Hampshire after nearly every major ice storm. A LiFePO4 solar station is the only backup that’s safe inside.
For most New Hampshire homes, yes. The state's defining hazard is ice — freezing rain that snaps trees onto lines and can leave homes dark for days, a week or more in rural co-op territory, as the December 2008 storm proved with roughly 400,000 outages. You don't need a whole-house standby unit, though: a solar generator like the Jackery HomePower 3000 keeps the furnace blower, fridge, Wi-Fi, and lights running for one to two days, is safe indoors, and never needs a fuel run on iced-over roads.
How bad was the 2008 New Hampshire ice storm?
It's the storm the state still plans against. In December 2008, freezing rain coated trees and power lines across New Hampshire, and the ice brought them down by the thousands — roughly 400,000 homes and businesses lost power, and some rural customers on Eversource, Unitil, and the New Hampshire Electric Cooperative waited a week or more in the cold for restoration. A solar generator is sized for exactly that kind of days-long winter gap.
Can a solar generator run my furnace during a New Hampshire outage?
It can run the electric blower and controls on most gas or oil furnaces, which is what actually stops when the power fails — the burner itself uses little electricity. A HomePower 3000 keeps that blower, a fridge, and lights going for one to two days. For a whole heating system plus a 240V well pump, step up to the 5000 Plus.
Isn't a gas generator the obvious choice for a cold New Hampshire winter?
It has real drawbacks here. A gas generator can't run indoors, has to be refueled in sub-freezing weather, and during a multi-day ice storm the roads and stations may be closed, so fuel runs out. A Jackery LiFePO4 station runs near 30 decibels, vents nothing, is safe inside, and recharges from its panels — no midnight trip to a shuttered gas station.
