What being snowed in does to a solar cabin

When a storm buries the array, the cabin lives on whatever is in the battery bank. If the weather also keeps you from clearing the panels, the bank only goes down. Add a cold snap, and the loads you rely on (water pump, heater fan, charger) all pull harder at the same moment.

A kit for that scenario has one rule: every critical function needs a backup that does not depend on the solar system. Light, heat, communication and information should all have a second way to work. The American Red Cross suggests that a stay-at-home kit hold at least two weeks of supplies, and a three-day go-kit you can carry if you need to leave to get warm. For a remote cabin, that is a useful benchmark for how long to plan.

Light that does not need the battery bank

Keep at least two headlamps and a lantern, each with spare batteries or a charged power bank. The Red Cross advises against candles because of fire risk and suggests battery-powered lights or flashlights. Store the light in a known place near the door and the bed, not in a drawer you have to find in the dark. For ideas on small lights, see our guide to lanterns and headlamps.

Heat: a backup that does not need the inverter

Heat is the highest-stakes item. If your main heat depends on a fan or igniter that uses battery power, you need a second option that does not. That may be a wood stove, or a heater rated for indoor use whose manual covers the cabin's ventilation. Follow its instructions for clearances and use. The Red Cross says to keep flammables at least 3 feet from space heaters and fireplaces, and never to heat a home with a cooking oven or stove.

The CDC recommends that fuel-burning equipment be vented outside, that wood-stove chimneys be inspected each year, and that a battery-operated CO detector and smoke detector be placed near the heated area. Keep a dry-chemical extinguisher close. Our cabin heating guide covers the options, and the propane and CO detector guide covers placement.

Power: protect the bank and keep a small reserve

Decide in advance which loads you will shed when the bank runs low: usually the water pump, the fridge and any heated accessories first. Make sure the low-voltage cutoff is set as your manual describes, which prevents deep discharge; see our low-voltage cutoff guide. Keep one or two charged USB power banks separate from the main system for phones and lights.

If you own a generator for dark spells, the safety rules above apply, and the way it connects to the cabin should follow the equipment manual and local code, with a licensed electrician doing any wiring. Our generator auto-start guide explains the basics. Clear the array with a soft brush on a long handle once it is safe to go outside.

Communication and information

Cell service may fail or not exist. Pack a battery-powered radio with spare batteries, as the Red Cross recommends, and a way to charge your phone. A two-way radio can reach people nearby, but GMRS requires an FCC license; the FCC says individuals who apply must be at least 18 and the license lasts ten years. See our GMRS radio guide and cell booster guide.

The most useful item is not gear: tell someone your dates and when you will check in, and agree what they do if you do not. Our pre-snow gear list covers ordering these items in time.

Food, water, warmth and first aid

• Water: The Red Cross suggests at least one gallon per person per day.
• Food: Items that need no cooking, in case the stove fuel or power runs out.
• Warm clothing and bedding: Hats, mittens, extra blankets or sleeping bags for everyone.
• First aid and medicine: A first aid kit and a supply of any prescriptions, with a card listing dosages.
• Tools: A snow shovel, ice melt and a way to clear the door.
