Home Battery Backup in Charlotte

Duke Energy prices a three-hour peak every weekday and can call critical peak days at 42.8¢. A battery charged off-peak covers both.

What a home battery runs during a Worcester winter outageThe grid is down and snow covers the array, so the grid-tied solar system produces nothing. The battery feeds a critical load panel, keeping the refrigerator, heating controls, well pump and networking running, while air conditioning, the electric range and the dryer stay off. A reserve floor is held back for outages.GRID DOWNSOLAR 0 kWFRIDGEHEATPUMPWIFIA/CRANGEDRYEROFFBATTERYreserve floor heldback for outages

The short answer

Charlotte is mostly served by Duke Energy Carolinas. On its Schedule RSTC time-of-use rate, on-peak is 6–9 p.m. summer weekdays and 6–9 a.m. winter weekdays, billed at 23.5¢ per kWh against 10.3¢ off-peak — and up to 20 Critical Peak Days a year at 42.8¢ (before riders, effective January 1, 2026).

A battery can carry part of the house through those windows and keep chosen circuits on in an outage. Under Duke's North Carolina net metering rider, a battery counts only if it is charged solely from your onsite solar, and excess energy is credited at just 4.53¢ per kWh.

Duke Energy rates in Charlotte

From Duke Energy Carolinas' North Carolina Schedule RSTC.

Two peaks a year, by season

On Duke Energy Carolinas' Schedule RSTC, on-peak is 6–9 p.m. on summer weekdays (May–September) and 6–9 a.m. on non-summer weekdays (October–April). Hours are Eastern Prevailing Time.

23.5¢ on-peak, 10.3¢ off-peak

RSTC energy charges before riders: 23.4984¢ per kWh on-peak, 10.2875¢ off-peak and 7.4375¢ in the discount hours, plus a $14.00 monthly basic customer charge (effective January 1, 2026).

Up to 20 Critical Peak Days

Duke can call up to 20 Critical Peak Days a year, when the peak hours are billed at 42.7695¢ per kWh. Notice is normally given by 4 p.m. the day before.

Where a battery fits in Charlotte

The daily peak, critical peak days, Solar Choice rules and backup circuits.

Shift the evening and morning peak

A battery charged in the discount or off-peak hours can carry part of the house through the three-hour on-peak window — and the more expensive critical peak hours when Duke calls them.

Solar Choice counts solar-charged storage

Under Rider RSC, Duke's North Carolina net metering rider, a battery is treated as part of the renewable system only if it is charged solely from your onsite renewable generation. Rider RSC requires an RSTC or RETC time-of-use rate.

Excess energy pays less than it costs

Rider RSC nets usage within each time-of-use period. Net excess energy left over is credited at 4.53¢ per kWh — so using your own stored solar at 6 p.m. is usually worth more than exporting it.

Choose the circuits that matter

Refrigeration, well or sump pump, furnace or heat pump controls, internet, lights and medical devices. A critical load panel decides what the battery carries in an outage.

Charlotte next to Oklahoma City and Danville

Oklahoma City is the opposite shape: OG&E's SmartHours rate puts all of its premium into summer afternoons, 2–7 p.m., with no winter peak. Charlotte's Duke rate moves its peak from summer evenings to winter mornings.

Over the Virginia line, Danville is a municipal utility with its own grid-scale batteries. Charlotte homeowners deal with an investor-owned utility, a time-of-use rate and a net metering rider that decides whether a battery counts.

Where these figures come from

Rates and net metering rules trace to Duke Energy Carolinas' North Carolina tariffs; the incentive to Duke's PowerPair trade-ally page.

What a home battery job with us covers

Installation of storage and the backup circuits behind it, with the siting and utility paperwork handled.

  • Battery installation

    Wall or floor-mounted storage installed to the listing and to the residential code sections that govern where it may go.

  • Backup and critical load panel

    Deciding and wiring which circuits stay live, and which must never be on backup — the choice that defines what an outage feels like.

  • Integration with existing PV solar

    Connecting storage to an array that is already on the roof, including whether the existing inverter supports it.

  • Transfer switch and disconnection

    The equipment that separates the house from the grid during an outage, which is what makes backup legal as well as possible.

  • Siting to code

    Location, clearances, separation and impact protection assessed against the adopted code before anything is mounted.

  • Permit, inspection and utility approval

    The electrical permit, the inspection, and the utility's own approval step where storage touches the service.

This is installation work. No runtime, capacity or incentive figure is quoted before your loads and your utility are confirmed. Coverage is confirmed per service area rather than promised as blanket availability.

What the work actually looks like

A battery job is an electrical job. The panel, the circuits and the disconnection are most of it.

What is PowerPair?+

A Duke Energy incentive program in North Carolina for solar paired with a battery. Duke's trade-ally page describes a one-time incentive of up to $9,000 and says capacity is limited and incentives are not guaranteed. Check Duke's current program page before planning around it.

How long will a battery run my house?+

It depends on capacity and which circuits you put on it, so we don't quote a runtime before seeing the panel.

Who installs it, and who is responsible afterwards?+

Seamless Home is the licensed contractor of record on the work it runs. Installation is performed by vetted installing partners engaged as our subcontractors, so the permit, the inspection and any correction notice carry one name. Coverage is confirmed per service area rather than promised as blanket availability.
