No storm reshaped New Jersey’s relationship with its power grid like Superstorm Sandy. When it came ashore near Brigantine in late October 2012, a record surge and hurricane-force winds knocked out power across PSE&G, Jersey Central Power & Light, and Atlantic City Electric territory, from the barrier islands to Newark and Jersey City, and some neighborhoods stayed dark for two weeks or more. New Jersey sits inside the PJM regional grid, but PJM manages the transmission backbone; it can’t reconnect the flooded substation or the downed pole on your street. That’s the job storage does. If you’re comparing New Jersey solar quotes, it’s worth being clear-eyed about it: panels alone lower the bill, but a battery is what actually keeps the lights on.
Sandy wasn’t a one-off
Eight years after Sandy, Tropical Storm Isaias proved the state’s grid still buckles under a summer storm, not just a hurricane. When it crossed New Jersey on August 4, 2020, JCP&L alone reported 788,000 customers impacted statewide, with more than 567,000 of those outages concentrated in Monmouth, Morris, and Ocean counties. Restoration crawled: it took roughly a week to reach 97% of affected customers, and residents’ frustration with the pace was loud enough that the state’s Board of Public Utilities opened a formal review of how JCP&L, PSE&G, and Atlantic City Electric had handled the storm. Two very different storms, eight years apart, landed on the same lesson: whatever the utility’s response time turns out to be, your own power comes from what’s already charged at your house.
What a solar quote usually leaves out
Rooftop solar is one of the best ways to cut a New Jersey electric bill: right up until the grid fails. A grid-tied system is required to shut down the instant the utility goes offline, because anti-islanding protection keeps your array from energizing lines that crews are repairing. So on the sunny morning after a nor’easter, your panels produce nothing for your own home. For a state with New Jersey’s coastal exposure (where Sandy, Isaias, and routine nor’easters all mean multi-day outages) that’s a real gap, not a hypothetical one.
How long each Jackery runs a New Jersey home’s essentials
Size against energy used per day, not the wattage printed on the box.
| Load | Typical draw | Energy per day |
|---|---|---|
| Fridge/freezer | ~150W running (cycling) | ~1,200Wh |
| Wi-Fi router | ~10W | ~240Wh |
| LED lights (ten bulbs) | ~50W | ~300Wh (6 hrs) |
| Phone and laptop charging | ~20 to 60W | ~150 to 250Wh |
| Window AC (summer storm) | ~900 to 1,200W | ~4,000 to 6,000Wh |
| Sump pump (coastal/river flooding) | ~800 to 1,300W while running | ~500 to 1,000Wh |
| Furnace blower (winter nor’easter) | ~300 to 600W | ~1,500 to 3,000Wh |
Fridge, lights, Wi-Fi, and phones come to roughly 1,900 to 2,000Wh a day. Add a window AC in an Isaias-style summer storm or a sump pump during coastal flooding and the day climbs toward 4,000 to 5,000Wh or more.
How to gauge your own storm risk
Two questions settle most of it. How exposed is your street? If a bad coastal storm or tropical remnant reliably darkens your block for a day or more, backup is more likely to be worth the cost, and the shore counties and low-lying river towns carry the highest odds. What truly has to stay on? For most homes it’s the fridge, Wi-Fi, phones, and a few lights, together only about 300W. If someone depends on medical equipment, or you want a window AC through a summer storm, the number, and the battery, grows.
Start with the essentials, scale up if the risk warrants
For keeping the core of a home running, the Solar Generator HomePower 3000 is the sensible starting point: about 3,072Wh and 3,600W, enough for a fridge, Wi-Fi, and lights for one to two days. Its bundle includes solar panels, so it recharges in daylight and keeps going through a multi-day storm, and at near 30 decibels with zero emissions it’s safe indoors: unlike a gas generator you can’t run in a flooded, closed-up house.
Current price of the HomePower 3000 at Jackery (panels included)
If you’re in a larger home, or want to carry central air through a long summer outage, step up to the Solar Generator 5000 Plus: 5,040Wh and 7,200W with both 120V and 240V, expandable to 60kWh, enough to run HVAC and several rooms at once. The HomePower 3600 Plus sits between the two: 3,584Wh, 3,600W, and expandable to 21kWh, a middle option for homes that want more runway than the base 3000 without stepping up to 240V.
| Unit | Capacity / output | Best for in New Jersey | Price |

| HomePower 3600 Plus | 3,584Wh · 3,600W · to 21kWh | A week-long restoration like Isaias, sump pump included | Check the price |
| Solar Generator 5000 Plus | 5,040Wh · 7,200W · 120V/240V · to 60kWh | Central AC through a Sandy-length outage | Check the price |

Battery vs gas generator after a coastal storm
A hurricane remnant or nor’easter is difficult weather for a gas generator: it has to sit outside in wind, rain, or floodwater, venting exhaust that’s deadly if it drifts back indoors. A Jackery is zero-emission, LiFePO4, and near-silent at about 30 decibels, so it runs safely from a closet or garage with the doors shut.
- Indoor safety and carbon monoxide. A battery station vents nothing and runs with the house sealed against wind or rain.
- Noise. About 30 decibels versus the 60 to 90 a gas generator runs at.
- Fuel in a storm. The battery is charged before the storm and refilled by the sun after. Gasoline has to be stored fresh, and flooded roads after a coastal storm can cut off the nearest station too.
- Maintenance. Oil, carburetor, and monthly test runs for gas. A monthly top-up for the battery.
- What gas still does better. A very long outage with no sun, and whole-house 240V at a lower upfront cost.
Set-up checklist before hurricane season
- Charge to full and top up monthly, whether it’s hurricane season or a winter storm watch.
- Keep it indoors and above flood level. A closet, upstairs room, or elevated utility space, never a low-lying garage on the shore.
- Map which outlets and which loads. Fridge, sump pump, router, one lamp per room. Tape the list to the unit.
- Buy extension cords rated for the load. A short 12-gauge cord for the fridge and sump pump runs.
- Test the sump pump or AC on the battery once before the season starts.
- Keep the panels accessible for daylight recharging if the outage runs multiple days.
- Pair the HomePower 3600 Plus with a transfer switch for hardwired circuits. Licensed electrician only.
- Keep a battery-powered CO alarm regardless. A neighbor’s gas generator can still put CO in your house.
Sandy and Isaias showed that long outages recur in New Jersey. If backup makes sense for your home, the practical time to decide is before the first storm warning of the season, when you can compare options without time pressure.
