Backup Power for South Carolina: Lowcountry Hurricanes and Upstate Ice
Charleston prepares for hurricanes, Greenville prepares for ice, and Helene showed the Upstate that hurricanes reach there too. Two plans for one state.

What's in this article
Helene came through the Upstate at the end of September 2024 and did what no one in Greenville had planned for — it took down trees and lines across the whole region and left some areas dark for more than a week. verify The Lowcountry, which had prepared for hurricanes for generations, was barely touched.
South Carolina is two states when the power goes out, and Helene rearranged which one had the bigger problem.
Why South Carolina is its own problem
The Lowcountry. Charleston, Beaufort, Hilton Head, Myrtle Beach — hurricane and tropical storm season from August to October, with storm surge, flooding, and hot humid restorations.
The Upstate. Greenville, Spartanburg, Anderson, the foothills — ice storms from freezing rain on the Piedmont, and now Helene-type wind events from hurricane remnants that reach further inland than anyone expected.
The Midlands in between. Columbia gets a bit of both, plus summer thunderstorms with the state's heaviest tree cover.
Four utilities. Dominion, Duke, Santee Cooper and the co-ops all restore on their own schedules with their own maps. Rural co-op restoration is slower.
The coast: recharging beats capacity
After a hurricane the sky clears and stays clear. A 1,000–2,000Wh unit with 400W of panels runs a fridge, fans, phones and internet indefinitely in post-storm sun. A bigger battery without panels runs out on day two.
Heat and humidity mean fans, not AC — a box fan on a battery does more than the wattage suggests, and a window unit empties a 2,000Wh pack in hours.
| Appliance | EcoFlow DELTA 21,024 Wh | Bluetti AC200L2,048 Wh |
|---|---|---|
| Full-size refrigerator~150W running, cycles ~35% of the time | 17 hr | 33 hr |
| Box fan~75W running | 12 hr | 23 hr |
| Wi-Fi router + modem~20W running | 44 hr | 87 hr |
| Phones and a laptop~65W running, cycles ~50% of the time | 27 hr | 54 hr |
For the full coastal plan, the hurricane checklist covers what to do the week before.
The Upstate: ice, and now wind
Ice storm outages are cold, grey and a day or three. Most Upstate houses heat with gas. Power the furnace blower through a transfer switch — a few hundred watts cycling — and the whole house stays warm on a 1,000Wh unit. The setup.
Under ice-storm sky, the car is the recharge.
What we'd buy, by situation
Charleston, Beaufort, Myrtle Beach — coast
1,000–2,000Wh plus panels. The Bluetti AC200L with two PV200s. The panels turn a two-day battery into a two-week system.
Greenville, Spartanburg, Anderson — Upstate
A 1,000Wh unit, a transfer switch, and — since Helene — panels too. The EcoFlow DELTA 2 wired to the furnace, with panels for the clear-sky week that a wind event leaves behind.
Rural co-op territory, anywhere on a well
2,000Wh class, panels, and the well-pump conversation. A submersible pump needs 240V and changes the whole budget. Get a standby generator quote alongside.
What not to buy in South Carolina
A coastal plan for the Upstate, or the reverse. They want different recharge strategies.
A battery as a reason to stay for a Category 4. Evacuate. Backup is for after.
A generator without stored fuel. After Helene, Upstate gas stations had no power for days. verify
The free things, which matter most
Know your utility. Dominion, Duke, Santee Cooper or a co-op — different maps, different schedules.
Fill the freezer with water jugs when the forecast turns.
Trim the pines over your service drop. Most Upstate outages start with a tree you can see from the house.
Register medical equipment. Free, one form, changes your priority in every utility's queue.
The picks, in detail
Specs come from data/products.json, so they're the same everywhere on this site.
EcoFlow
EcoFlow DELTA 2
The one most people should buy. It refills fast enough that a short sunny break between storm bands actually matters.
- Capacity
- 1,024 Wh
- AC output
- 1,800W
- Weight
- 27 lb
What's good
- Wall recharge is genuinely quick — useful when power flickers back for an hour
- LiFePO4 cells, so it tolerates being left plugged in for years
- Six AC outlets means no daisy-chained power strips on the kitchen counter
- Add an extra battery later instead of buying a whole second unit
What's annoying
- The fan is audible in a quiet bedroom at night
- 1800W ceiling rules out most space heaters and hair dryers
- Expansion batteries cost nearly as much as the unit itself
Who this is wrong for
Anyone who needs to power a well pump, an electric water heater or a central AC. It will not start them, and it is not a whole-home unit.
Bluetti
Bluetti AC200L
Specs unverifiedA lot of battery for the money, with the port selection of a small workshop.
- Capacity
- 2,048 Wh
- AC output
- 2,400W
- Weight
- 61.9 lb
What's good
- Expandable, unlike most Bluetti units at this size
- A genuinely useful spread of ports including a 30A RV outlet
- Fast recharge for a 2kWh unit
What's annoying
- Shorter warranty than EcoFlow and Jackery offer
- Big and awkward to store
- Bluetti's US service turnaround has been inconsistent
Who this is wrong for
Small apartments. It's physically large and you will trip over it.
Bluetti
Bluetti PV200 200W Solar Panel
Specs unverifiedThe most watts per dollar in folding panels, with a case that feels like it'll outlast the warranty.
What's good
- Strong output for the money
- MC4 makes it universal across brands
- Durable long-fiber ETFE surface
What's annoying
- Four-fold design is awkward in wind
- No integrated USB output
- Kickstand angles are limited
Who this is wrong for
Quick grab-and-go trips. Unfolding four panels in wind is a two-person job.

Founder and editor, GreenCommuteGuide
I started GreenCommuteGuide because backup power is sold with numbers that sound impressive and mean very little — watt-hours on the box, surge ratings that turn out to be a boost mode, charge times quoted to 80% and printed as though they were full. I set the rules this site runs on: every spec is checked against the manufacturer's own documentation, anything we have not verified is marked as unverified on the page rather than quietly published, prices are never shown because they go stale, and every review names at least one product not to buy and who it is wrong for. Where I have not tested something myself, the page says so.
- · Sets and enforces the editorial standards on this site — unverified claims are flagged on the page, and the build fails if they are not
- · Specs are taken from manufacturers' own published documentation, never from retailer listings, and the source and date are recorded for each product
- · No payment is accepted for a rating, a ranking, or a positive verdict
