In late January 2009, a slow-moving ice storm coated Kentucky from the Purchase region to the Bluegrass, snapping power lines and tree limbs under the weight of the ice. It became the largest power outage in the state’s history, and in some rural counties LG&E, KU, and the local electric cooperatives took weeks to get everyone back on. Twelve years later, western Kentucky lost power a different way. On December 10, 2021, a violent tornado outbreak tore through Mayfield and the surrounding Purchase region, killing 22 people and leveling nearly 500 homes and businesses. Every customer of Mayfield Electric and Water Systems lost power that night, and Kentucky’s emergency management director said 28,000 homes and businesses statewide were still dark two days later: the town’s substation ran in emergency mode for weeks while crews rebuilt it from the ground up. Kentucky’s grid is split (LG&E and KU cover the center of the state, while Kentucky Power and a patchwork of co-ops serve the mountains and the far west, including Mayfield’s territory) but the lesson from both 2009 and 2021 crossed every service territory: whether it’s ice or a tornado that takes the grid down, restoration in Kentucky is measured in days and weeks, sometimes months, not hours. If you’re comparing Kentucky solar quotes, it’s worth knowing that a grid-tied rooftop system shuts off in that outage too, unless you also have battery storage.
Two disasters, twelve years apart, the same lesson
Ice and tornadoes fail a grid in opposite ways. The 2009 storm built up slowly over days, coating thousands of miles of line and tree limb until the weight brought them down almost everywhere at once: a utility isn’t fixing one big break, it’s fixing thousands of small ones, span by span. Mayfield’s tornado did in minutes what the ice storm did over days: it didn’t just snap lines, it took out the substation the lines run from, which is why “restoration” there meant rebuilding infrastructure, not just re-stringing wire. Between winter ice storms that can idle whole counties and the spring and early-winter tornadoes that have raked Louisville, Bowling Green, Paducah, and now Mayfield, Kentucky homeowners lose power from both ends of the calendar and for very different reasons. The one constant is that a long outage is a real possibility here, so it is worth planning for several days on your own.
Start with the loads that matter
Most homes overestimate what they need to keep running. A refrigerator draws around 150W, ten LED bulbs about 50W together, a router near 10W, and phone charging about 20W. Add a fan or a couple of chargers and you’re near 300W of steady draw: enough to keep food cold, phones alive, and a room lit through the worst of a storm.

How long each Jackery runs a Kentucky 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 |
| Furnace blower (winter ice storm) | ~300 to 600W | ~1,500 to 3,000Wh |
| Wi-Fi router | ~10W | ~240Wh |
| LED lights (ten bulbs) | ~50W | ~300Wh (6 hrs) |
| Phone and laptop charging | ~20 to 60W | ~150 to 250Wh |
| Box fan | ~60 to 100W | ~500 to 800Wh |
| Sump pump | ~800 to 1,300W while running | ~500 to 1,000Wh |
| Space heater | 1,500W | Not recommended |
Fridge, lights, Wi-Fi, and phones come to roughly 1,900 to 2,000Wh a day. Add a furnace blower in a winter ice outage and the day climbs toward 4,000 to 5,000Wh.
The Solar Generator HomePower 3000 is built for the lighter end of that range. It delivers roughly 3,072Wh and 3,600W, covers essentials for one to two days, and its bundle includes solar panels so it recharges mid-outage while the grid is still down.
HomePower 3600 Plus. 3,584Wh and 3,600W, expandable to 21kWh: enough to carry a furnace blower through a multi-week restoration like the one Mayfield needed.
Solar Generator 5000 Plus. 5,040Wh, 7,200W, 120V and 240V, expandable to 60kWh: the only one of the three built to run central air conditioning on 240V alongside the essentials in a Lexington or Louisville home.

Battery or gas generator when you’re cut off
An ice storm or a leveled neighborhood is the worst case for a gas generator. It runs loud, it needs fuel from a station that may be closed, damaged, or unreachable, and its exhaust means it can never come inside: right when the weather or the wreckage is pushing people to bring it too close to the house. Every winter, that trade-off leads to carbon-monoxide emergencies, and after a tornado a generator sitting in the open is one more thing that can be stolen or damaged by debris.
- Indoor safety and carbon monoxide. A battery station vents nothing and can run with the doors shut, wherever you’re sheltering.
- Noise. About 30 decibels versus 60 to 90 gas generators run at.
- Warning time. An ice storm gives a day or two of notice. A tornado gives minutes. A battery that’s already charged is ready either way.
- Cold starting or no starting at all. Push a button, rather than fighting a pull cord in the dark, or discovering your generator was in the part of the garage that’s no longer standing.
- 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 the next storm
- Charge to full and top up monthly. Kentucky’s worst outages have come in January and December alike: there’s no single season to relax in.
- Keep it indoors, above freezing in winter. A closet, utility room, or heated basement, never an unheated garage.
- Map which outlets and which loads. Fridge, furnace blower, 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 furnace runs.
- Test the furnace on the battery once in autumn, before the ice season arrives.
- Keep the panels accessible and easy to grab. A tornado warning gives minutes, not hours, to gather what matters.
- Pair the HomePower 3600 Plus with a transfer switch for hardwired circuits like the furnace. Licensed electrician only.
- Keep a battery-powered CO alarm regardless. A furnace or a neighbor’s generator can still put CO in the house.
Backup is easier to set up before the freezing rain or the tornado watch is in the forecast than during the scramble afterward, when the shelves are often bare. Whichever unit you choose, charge it and learn which outlets carry which loads so it is ready when the lights flicker. Prices change often, so compare current prices before deciding.
