What a 2-day ice storm / Nor’easter outage actually needs
Ice and wet Nor’easters knock out suburban feeders for about two days more often than a week. The job is cold, often sunless for panels, and unforgiving on pipes, sumps, and medical loads. This is not another “best of 2026” list, not a hurricane week page, and not a portable-to-panel how-to.
Edited by K Singh. contact@outageshield.com. Manufacturer pages and dated list prices only. No invented homeowner stories. No test lab.
Write the must-run circuits first. Then check voltage, surge, and usable kWh. Brands come after the job is honest. For fuel-vs-battery math on a longer storm week, use generator vs battery vs hybrid. For hour-by-hour failure order, see what dies first. Mid-Atlantic hurricane / remnant framing stays on the storms page.
1. Duration first — 2-day ice vs multi-day hurricane
| ~2-day ice / Nor’easter | Multi-day hurricane / remnant week | |
|---|---|---|
| Typical planning window | About 36–60 hours of feeder / tree damage | Often 3–7+ days of dirty power and delayed crews |
| Air and pipes | Cold; freeze risk if heat and water stop | Warm or humid; food and flood more than freeze |
| Solar recharge | Usually useless under ice cloud / wet snow | Often useless at landfall; may return after sky clears |
| Water loads | Sump (melt + rain) and well if you have them | Sump + well still matter; flood height dominates placement |
| Fuel logistics | Iced roads delay propane / gas delivery | Flooded roads and queues; still outdoor-only generators |
A 2-day ice outage is enough to spoil a fridge, stop a CPAP night, freeze pipes if heat controls die, and flood a basement if the sump stops. It is not automatically a 40 kWh whole-home week. Size for the cold, short window — then expand only if your house actually needs it.
2. Must-run circuit list (before any brand kit)
Check only what you will keep. Everything else is shed. Do not buy inverter watts for a dryer you will not run.
| Circuit / load | Why it matters in ice | Typical running note | Ice-specific honesty |
|---|---|---|---|
| Refrigerator / freezer | Food loss in ~1–2 days if doors open | ~100–200 W average if disciplined | Keep; door discipline beats a bigger pack |
| Furnace control / blower (gas) | Pipe freeze and cold nights | Controls modest; blower often a few hundred W | Control + blower ≠ whole heat-pump compressor |
| Space heat (if used) | Last-resort warm room | Many space heaters 1,000–1,500 W | Honest: one heater can empty a ~4 kWh pack in hours |
| Router / ONT / phones | Outage info, medical apps, family | ~20–40 W | High value, tiny Wh — keep |
| CPAP | First night medical | ~30–90 W; humidifier costs more | Dial humidifier down for nights, not hours — CPAP + fridge |
| Sump pump | Meltwater / rain into basements | Often 120 V cycling; surge on start | High value if you have a basement |
| Well pump (if present) | No water once pressure tank empties | Often 240 V; LRA is the gate | Fail closed on surge before kWh — well pump |
Planning average for fridge + CPAP + router often lands around 0.25–0.40 kW if you are strict. Across two days that is roughly 12–20 kWh before inefficiency, door openings, a sump cycle, or a space heater. A single 3.84 kWh station is a night or two of essentials — not a silent whole house — unless you recharge. Run your watts on the runtime calculator. Tick boxes on the essentials checklist.
3. Voltage · surge · usable-kWh gates
Fail any gate and the product is the wrong class for that job, no matter the brand.
- Voltage. Fridge, CPAP, router, many sumps: 120 V. Many wells and some dryers: 240 V. A 120 V-only box fails the well before Wh matters.
- Surge / start. Locked-rotor amps on the pump badge beat marketing “runs a well.” Soft-start kits cut start current. Extra batteries do not buy start current.
- Usable kWh. For ice, assume little or no solar for 48 hours. Usable energy ≈ nameplate × depth-of-discharge honesty × inverter efficiency — then divide by your average kW. Recharge from the wall before the storm, or from a generator if you already own one.
| Job | Voltage | Surge gate | Usable kWh for ~2 days |
|---|---|---|---|
| Fridge + CPAP + router | 120 V | Modest | ~12–20 kWh planning band if no recharge |
| Gas furnace control + blower | Usually 120 V | Confirm nameplate | Add blower hours to the essentials math |
| Sump | Often 120 V | Start surge on each cycle | Energy is usually small; start reliability matters |
| Well | Often 240 V | LRA first | Irrelevant until it starts — then running hours |
4. Shop-ready paths vs installer (dated 11 Sep 2026)
Shop-ready means you can order hardware without waiting on a Tesla or Powerwall quote. Automatic whole-home still means a panel kit and an electrician in most houses. No federal 25D subtraction on a homeowner-owned 2026 install.
Anker SOLIX F3800 class
Anker SOLIX US PDP (ankersolix.com/products/f3800, checked 11 Sep 2026): 3.84 kWh, 6,000 W continuous, 120/240 V class. Base/list path price $2,199.99. Live JSON-LD Offer and a $200 WSTD promo also showed $1,999.99 the same day — cite the sale only if your cart still shows it. Expand with BP3800s for a real 2-day essentials bag; one pack alone is short if you add heat or a sump.
Ladder: Anker F-series.

Dedicated ultra-extra PDP still showed $2,399 the same day — this site follows the Ultra X rail lock. For ~2 cold days of essentials, the starter Wh is in the right ballpark before space heaters.

5. Generator vs battery for ice
Battery favors ice when the critical list is fridge, medical, networking, furnace control, and maybe a sump — and you want silent indoor storage with no CO in a closed garage. Charge to 100% from the wall before the forecast icing. Do not plan on folding panels under gray ice cloud.
Generator risk rises on ice because fuel delivery and safe outdoor placement get harder when roads glaze. A dual-fuel plant still wins on multi-day Wh and some 240 V starts, but only if you already have fuel on site and a safe outdoor plan. Never run a generator indoors or in an attached garage.
Hybrid only if you already own the generator: battery for quiet nights and UPS-class medical loads; generator for recharge and the high-surge 240 V job. Do not buy both at whole-home scale before you have a written circuit list. Full fork: generator vs battery vs hybrid.
- ~2 cold days, essentials only → expandable 120/240 V portable (F3800 / DP3 class) plus same-brand extras if Wh is short.
- ~2 days + automatic circuits / more Wh → Ultra X class (± SHP3) or EP900 stack — confirm live carts.
- Well on the must-run list → fail closed on 240 V + LRA first; see well pump.
- Already own a generator → hybrid pattern; do not invent a second plant “just in case.”
