SolaHD, earlier Sola Hevi-Duty, is a long-running brand of dry-type and power-conditioning transformers. Its equipment is common in industrial control panels and plant distribution, but the brand name alone does not tell us what a seller has. A ventilated distribution transformer, a panel-mounted control transformer and a power-conditioning unit need different identification details.
We buy eligible used, new-surplus and decommissioned SolaHD transformers from sellers throughout Virginia. Older Sola Hevi-Duty labels belong in the same equipment inquiry; send what the plate actually says rather than guessing a current model equivalent. Our transformer brand directory covers other makes you may have in the same surplus inventory.
01Which SolaHD Transformers Do We Buy?
We buy general-purpose SolaHD dry-type transformers within our size range: single-phase from 10 kVA and three-phase from 15 kVA. For plant distribution equipment, the useful starting point is rated kVA, primary voltage, secondary voltage and phase. A three-phase unit marked 480 V primary and 208Y/120 V secondary serves a different application from a single-phase unit with the same brand label.
Control and power-conditioning transformers require a closer look at the equipment category and rating. Many control-panel transformers are rated in VA rather than kVA and fall below our minimum sizes. Send the exact rating and catalog number for larger units, and identify each transformer separately when it is part of a mixed lot.
- General-purpose dry-type units: photograph the rating plate and enclosure.
- Control transformers: include VA or kVA, input and output voltages, and catalog number.
- Power-conditioning units: include the complete model designation and rated output.
- Failed or damaged transformers: disclose the problem; purchase review is case by case.
02Read the SolaHD or Sola Hevi-Duty Nameplate
Send a straight-on photo that keeps the full nameplate readable. We pay attention to the catalog or model number, serial number, kVA, phase, frequency, primary and secondary voltages, and tap information. On dry-type units, temperature rise, insulation class and any enclosure designation also help distinguish otherwise similar equipment. Use our transformer nameplate guide if an abbreviation is unclear.
Include the manufacturing year when it is explicitly shown. If the plate has only a serial number or date code, photograph it without assigning a year from memory. Older Sola Hevi-Duty lettering is not a reason to leave a transformer out of your inventory, but neither the label style nor the enclosure paint reliably establishes its age.
- Capture wiring diagrams and voltage connection labels in separate close-up photos.
- Record ratings exactly, including VA versus kVA and single-phase versus three-phase.
- Photograph a damaged plate from several angles rather than filling in unreadable fields.
- Include any separate model label on power-conditioning equipment.
03Condition Details That Matter on Dry-Type Units
We pay attention to enclosure condition, terminal damage, missing covers and signs of overheating. Photograph accessible areas showing corrosion, discoloration, broken insulating parts or debris. State whether the transformer was operating when removed, held as a spare or taken out of service after a fault. Those descriptions mean different things; use the one supported by your records.
Storage conditions also matter. Tell us whether the unit has been kept indoors, exposed to weather or stored where moisture could reach the windings. Share existing test reports if available, but do not energize equipment or open energized compartments to prepare an inquiry. Our dry-type transformer buying page explains the broader equipment category.
04Separate Distribution, Control and Conditioning Equipment
When you sell SolaHD transformer inventory from a plant, separate larger distribution units from small panel components. A control transformer typically supplies a control circuit at a specified secondary voltage; it should not be described as a plant distribution transformer simply because it came from industrial machinery. Listing the actual rating avoids confusion about size eligibility.
Power-conditioning equipment needs its exact model and function identified rather than a general description such as “voltage transformer.” Do not assume that a conditioning unit is interchangeable with a general-purpose dry-type transformer having a similar output voltage. If the equipment remains inside a cabinet, show the complete assembly and the transformer label, and state what is included in the sale.
05Typical Sources of SolaHD Surplus in Virginia
SolaHD inventory can become available during machinery replacement, control-panel upgrades, plant distribution changes and spare-parts cleanouts. A Virginia facility may have an unused replacement transformer on a shelf alongside a used unit removed from service. Label those conditions separately, and explain whether a boxed unit has been installed before or remains new surplus.
We serve sellers in every region of Virginia. For a plant shutdown or warehouse lot, group equipment by model and rating rather than describing everything as “Sola transformers.” Keep photos tied to inventory numbers so similar enclosures are not confused. For example, a 25 kVA single-phase transformer should have its own identification even when it sits beside several three-phase units.
06Prepare a Clear SolaHD Equipment Inquiry
To sell SolaHD transformer equipment, send clear nameplate and overall photos, location, quantity and condition notes through our equipment offer form. We review the information and may ask about test data, PCB status or site access. If the equipment fits, our written offer spells out price, freight, loading and payment terms; pickup is scheduled with you, and payment follows those terms. See how the buying process works for details.
Keep identification and removal planning separate. We do not perform electrical disconnect work; sellers use their own qualified electricians to de-energize and disconnect equipment. PCB status must be disclosed and documented where applicable. We do not ask sellers to drain fluid. SolaHD and Sola Hevi-Duty names describe the equipment only; Virginia Transformer Buyers is not affiliated with the manufacturer.
Frequently asked questions
Do you buy transformers labeled Sola Hevi-Duty instead of SolaHD?
Yes, we buy eligible transformers carrying the earlier Sola Hevi-Duty name as well as SolaHD labels. Send the original catalog number, serial number and electrical ratings rather than substituting a newer model name. Our minimum sizes are 10 kVA single-phase and 15 kVA three-phase. Failed or damaged units are reviewed case by case.
Can I sell a small SolaHD control transformer from a machine panel?
A small control transformer below 10 kVA single-phase or 15 kVA three-phase is outside our stated buying size range. Check whether its plate lists VA or kVA before submitting it. For example, 500 VA equals 0.5 kVA, not 500 kVA. Include larger eligible transformers separately if you are listing a mixed machinery or panel inventory.
What photos do you need for a SolaHD power-conditioning transformer?
Send the complete model label, electrical rating plate and overall photos of the power-conditioning equipment. Include input and output ratings, frequency and any separate labels identifying the assembly. If it is mounted in a cabinet, state whether the cabinet and associated components are included. Clear identification helps distinguish it from a standard general-purpose transformer.
Can I sell a SolaHD transformer with an unreadable serial number?
An unreadable serial number does not automatically rule out a SolaHD transformer, but identify the missing information clearly. Send close-up photos of the plate, catalog number, ratings and any other labels. Existing inventory records may help connect the unit to its documentation. Do not invent a serial number or manufacturing year to complete the listing.
Do unused SolaHD spare transformers need their original boxes?
Original boxes are useful for identification, but the transformer’s own nameplate and actual condition are more important. Photograph both the packaging label and the unit when safely accessible. State whether it has ever been installed, how it was stored and whether any parts are missing. A box alone does not establish that equipment is unused.
Will you review a SolaHD transformer that overheated or failed?
Yes, failed SolaHD transformers are reviewed case by case, with the failure disclosed. Describe overheating, winding faults, damaged terminals or other known problems and include existing test data if available. Do not describe a failed unit as working surplus. Leave it de-energized, and use your own qualified electrician for any required electrical disconnection.
