What we buy
Ranges we buy on this page
Transformer Buyers NC buys used, surplus, failed and obsolete transformers from battery storage facilities across North Carolina.
For storage projects paired with eastern North Carolina solar farms, the nameplate, outage boundary and interconnection schedule shape what can leave the site and when.
| Phase | kVA | Voltage | Fluid |
|---|---|---|---|
| 1-phase | 10 - 333 kVA | up to 25 kV | Liquid or dry |
| 3-phase | 50 - 20,000 kVA | 115 kV | Liquid or dry |

Fast offers
A written offer the same business day, based on your photographs.
Dedicated logistics
Our own crew, trailer and crane, not a brokered haul.
No broker fees
One buyer from first call to cleared pad, with nothing skimmed.
How it works
Six steps from photograph to payment
- 01
Take pictures
Photograph the nameplate, the inside of the cabinet and the tank from both ends. Four frames on a phone are enough to price most units.
- 02
Send them to us
Email or text the photographs with the site address and whether the unit is still energised. We reply the same business day with questions or a number.
- 03
Review the offer
The offer names the unit, the site, the price and the pickup window. It is written, dated and good for thirty days unless the unit changes hands.
- 04
We schedule freight
A crew, a trailer and a crane if the pad needs one. You get the date and the arrival window, and the site does not have to close for it.
- 05
Testing on arrival
Winding resistance, insulation resistance and a turns ratio check, plus oil analysis where the unit is liquid-filled. Results travel with the unit.
- 06
Get paid
Payment is released against the signed bill of sale and the scale ticket, by check or ACH, with the paperwork copy left on site.
What we handle
The parts sellers dread
Rigging
Crane, skates and a route survey for anything that will not roll onto a trailer.
Oil containment
Pans, absorbent and a spill plan before a drain plug is touched.
Bill of sale
A document that clears a lien, a lease or a bankruptcy file, not a handwritten note.
PCB paperwork
Testing and manifesting for pre-1979 oil, handled before the unit moves.
On the ground
How Battery Storage use power
Battery storage moves power in both directions: into batteries during charging and toward the grid during discharge. The transformer sees a fast-cycling load with high harmonic content associated with inverter operation.
Loading records should distinguish charging duty, discharge duty and periods when auxiliary equipment alone remains energized.
Inverter controls and filtering affect the harmonic spectrum, so the storage duty cannot be judged from kVA alone. Before releasing a failed transformer, preserve relay targets, oil test reports and inverter event logs.
Those records help separate winding damage from a cable fault or an external protection operation.
Local reality
The equipment you will find
Battery storage sites can hold padmounts, inverter-duty units and substation transformers. A padmount may connect an inverter block to a medium-voltage collector circuit; a larger substation unit serves the grid interface.
Record each unit separately rather than treating every tank inside the battery fence as identical equipment.
Nameplates should show kVA or MVA, primary and secondary voltage, impedance, cooling designation and winding connection. Include photographs of bushings, elbows, radiators and fuse compartments where accessible without exposure.
An inverter-duty designation matters, but it does not replace the actual ratings or the manufacturer's connection diagram for that unit.
Around the site
The state's Battery Storage footprint
In North Carolina's eastern counties, storage projects paired with solar farms may share collector roads, substation access and portions of the interconnection equipment.
Establish whether the transformer belongs to the battery project, the solar owner or the utility before assigning removal work or marking a tank for pickup.
An eastern North Carolina solar site can have narrow aggregate roads between panel rows and drainage ditches beside the storage compound. A route adequate for service trucks may not accommodate a loaded lowboy.
Provide the entrance location, culvert restrictions and turning area rather than relying on a general site address.
Where it sits
The decision chain
The battery project owner usually controls asset disposition, while an EPC contractor may still control construction access or warranty documentation. Utility-owned interconnection transformers require a separate authorization path.
Identify the owner of each serial number and obtain written release before a crane crew enters the fenced storage compound.
For a failed inverter-duty unit, the engineer, insurer and manufacturer may need photographs or samples before removal. A bankruptcy trustee may instead require an asset schedule and proof of ownership.
Keep those approvals tied to the specific transformer, especially where solar and storage equipment sit behind the same gate.
On the ground
Schedule and regulatory pressure
An interconnection date drives the battery storage schedule, and the transformer is the long-lead item. Removing a surplus or failed unit must not block replacement delivery, cable termination or commissioning.
Coordinate the lift window with the EPC schedule and the utility's approved switching plan for the affected collector circuit.
Disconnection requires qualified personnel, isolation, verification of absence of voltage and grounding under the site's procedures. Battery containers and inverter circuits can remain separate hazards even after the transformer is isolated.
Document oil condition and applicable PCB information, and assign responsibility for spill control and any required waste handling.
Local reality
Removal logistics
Start the lift plan with transformer weight, dimensions, lifting points and the condition of the tank base. Radiators, bushings and cable boxes may change transport clearance.
On a battery compound, crane outriggers must avoid buried collector cables, grounding conductors and duct banks shown on the site drawings before setup.
Confirm whether the padmount can leave intact or whether accessories need removal under an engineered handling plan. A spreader bar may be necessary to protect lifting geometry.
Keep the lowboy route clear of battery container doors, fire access lanes and the space reserved for the incoming replacement transformer.
Around the site
What to send us
Send a readable nameplate photograph, serial number, equipment count and the North Carolina site location. Include overall tank photographs and the stated operating condition: energized, disconnected, failed or never commissioned.
For an inverter-duty transformer, provide its drawing or specification sheet and identify the battery inverter block it served.
Add the required removal date, ownership authorization and contact for site access. Note oil leaks, damaged bushings, missing radiators and any retained cables or elbows.
Include available weight information, crane access photographs and the interconnection schedule if pickup must occur before replacement equipment reaches the battery storage pad.

Questions
Straight answers
Equipment types
Can you buy failed battery storage transformers?
Yes. Transformer Buyers NC buys failed units as well as used, surplus and obsolete equipment. Identify the failure condition and include nameplate photographs, oil leaks and visible bushing damage. Preserve inverter event logs and any evidence the manufacturer or insurer needs before authorizing removal.
Service area
Who authorizes removal at a shared solar site?
The owner of the specific transformer must authorize its release. A shared solar and battery storage fence does not establish common ownership.
Payment
What helps plan pickup before battery commissioning?
Provide the interconnection date, replacement delivery window and approved isolation schedule. Nameplate data, transport dimensions and verified weight support the handling plan. Photographs of the storage entrance, crane setup area and collector road help identify conflicts with battery fire lanes or incoming transformer placement.
Logistics
The decision chain: what should a seller know?
The battery project owner usually controls asset disposition, while an EPC contractor may still control construction access or warranty documentation. Utility-owned interconnection transformers require a separate authorization path.
