BC555 Black Catalogue Record / HY555-B120DDD 535–555W Module

The website calls this product BC555-B120DDD Black, while the attached PDF identifies HY555-B120DDD and lists HY535 through HY555 power bins without adding “Black” to the model string. For the HY555 bin the PDF shows 555 W, 38.07 V Vmpp, 14.58 A Impp, 45.49 V Voc, 15.43 A Isc and 24.59% efficiency. It also displays a black appearance, 1990 × 1134 × 30 mm, 27.5 kg ± 3%, N-type HYBC, bifacial/load/fire/warranty claims and certification logos. The BC/HY and Black-variant identity must be formally mapped to the delivered BOM, nameplate and documents.

Identity conflict: catalogue/URL use BC555-B120DDD Black; the PDF cover/table use HY555-B120DDD and do not include “Black” in the model string.

Current document status

A local two-page PDF is attached and visually verified. Request formal BC-to-HY and Black-variant cross-reference, nameplate/BOM/front-rear appearance specification, model-covered certificates/reports, load/fire evidence, installation manual, signed warranty and current packing/traceability documents.

Verified PDF evidence

Separate catalogue alias, PDF model family, 555 W bin and Black variant

Four identity layers currently depend on one PDF and require a formal commercial cross-reference.

BC/HY and Black mismatch

The catalogue says BC555-B120DDD Black; PDF pages say HY555-B120DDD and the family table lists HY535–HY555-B120DDD. The PDF image is black, but the model string does not encode Black.

Exact HY555 electrical bin

The 555 W column shows 38.07 V Vmpp, 14.58 A Impp, 45.49 V Voc, 15.43 A Isc and 24.59% efficiency; lower family bins have different values.

Working and temperature data

The HY555 working row shows 427 W, 36.01 V, 11.86 A, 43.21 V and 12.44 A at stated NOCT conditions; coefficients are -0.26/-0.22/+0.05%/°C.

Mechanical/PDF claims

The PDF lists N-type HYBC, 2.0 mm glass, anodized frame, IP68 box, MC4-compatible, ±300 mm cable, black imagery, bifacial/load/fire/warranty statements and logos.

BC555 Black/HY555 procurement checks

Six checks before approving the full-black 555 W supply

Aesthetic appearance and technical identity must both be controlled in the PO and sample approval.

Formal model mapping

Require manufacturer letter mapping BC555 Black to HY555-B120DDD, full sellable code, nameplate, factory and certificate/warranty models.

Black appearance and BOM

Approve front/rear colour, frame, cells, busbar visibility, back material/glass, encapsulant, junction box, cable and connector against a signed golden sample.

Exact 555 W bin

Specify HY555/555 W, flash distribution and 0 to +3% tolerance; prohibit substitution with HY535–550 without written approval.

String and BOS fit

Use 45.49 V Voc, 38.07 V Vmpp, 15.43 A Isc and 14.58 A Imp with temperature/design factors against inverter, connectors, cables and 30 A fuse.

Claims and documents

Request load/fire/PID/IEC reports, certificate numbers and signed 25/30-year warranty instead of accepting marketing text or logos alone.

Packing and inspection

Confirm 36/pallet, 792/40-HQ, pallet size/1020 kg, colour/appearance inspection, flash/EL criteria, serial traceability and damage process.

Black variant and evidence boundaries

Black appearance does not prove a unique certified BOM or higher energy yield

The aesthetic variant must be tied to an exact model, sample, BOM, certificate and warranty.

Black is not encoded in the PDF model

The file name and catalogue say Black, but the PDF model string is HY555-B120DDD. Require formal variant naming and nameplate/BOM mapping.

Full-black is not a performance advantage

Do not claim lower temperature or higher yield from appearance. Use the exact electrical coefficients and project thermal/energy model.

Load/fire/certificate logos need evidence

5400/2400 Pa, Class A, IEC/TÜV/MCS/CE graphics require reports/certificates showing exact model/variant, factory, test conditions and validity.

Warranty graphics need signed terms

25-year product, 30-year linear and 88.85% graphics do not define exclusions, degradation schedule, remedy, claimant, labour/freight or transferability.

BC555 Black / HY555-B120DDD FAQ

Questions created by the alias and aesthetic variant

The golden sample, model cross-reference and exact documents must agree.

Does the PDF identify the model as BC555 Black?

No. Its cover and table use HY555-B120DDD; Black appears in the website/file context and imagery, not the PDF model string. Require formal cross-reference.

Does the datasheet cover only 555 W?

No. It lists HY535, 540, 545, 550 and 555-B120DDD. Specify the 555 W bin and flash/tolerance controls in the PO.

Does full-black appearance improve output?

Do not assume so. Appearance is a BOM/aesthetic requirement; use the exact electrical data, temperature coefficients and project conditions for performance.

How should the Black variant be inspected?

Use a signed golden sample and criteria for colour uniformity, cells/busbars, frame/rear appearance, label/model, connector/cable, EL, flash, dimensions, packaging and serials.
