TC72N-550 production-batch evidence review
TC72N-550 550W N-Type TOPCon 144 Half-Cell Module
The TC72N-550 internal record describes a 550 W, 21.3% efficient N-type TOPCon bifacial dual-glass module with 144 half-cells. Its STC values are 41.8 V Vmpp, 13.16 A Impp, 49.8 V Voc and 13.93 A Isc. The module is listed at 2278 × 1134 × 30 mm and 27.4 kg with 2.0 + 2.0 mm glass, 1500 V maximum system voltage and a 30 A series fuse. Exact factory suffix, BOM, connector/cable, mechanical loads, certificates and production-batch packing remain to be approved.
Current source identity: TC72N-550 internal single-bin record; no released factory datasheet, manufacturer identity or certificate package is attached.

Current TC72N-550 evidence
Keep the 72-format electrical and mechanical record distinct
The 550 W row must not inherit size, current or cell-count values from TC54N or TC66N products.
550 W STC row
The record lists 550 W, 41.8 V Vmpp, 13.16 A Impp, 49.8 V Voc, 13.93 A Isc, 21.3% efficiency and 0 to +5 W tolerance.
144 half-cell format
2278 × 1134 × 30 mm, 27.4 kg, 2.0 + 2.0 mm glass, anodized frame and IP68 junction box are displayed.
Temperature/system labels
Pmax -0.29%/°C, Voc -0.24%/°C, Isc +0.04%/°C, 43°C ± 2°C NOCT, 1500 V and 30 A fuse are listed.
Missing batch identity
Manufacturer, full suffix, cell/BOM code, connector maker/model, cable length, clamp zones, mechanical loads and certificate revision are absent.
TC72N-550 procurement checks
Six checks before approving the alternate 144-half-cell format
Electrical, roof/ground structure and logistics decisions must use this exact geometry and current.
Full model and BOM
Freeze manufacturer, suffix, cells, glass/encapsulant, frame, junction box, connector, cable, nameplate and factory before sample approval.
String voltage/current
Use 49.8 V Voc, 41.8 V Vmpp, 13.16 A Impp and 13.93 A Isc with temperature/design factors against inverter and BOS limits.
Format and handling
Confirm 2278 mm length and 27.4 kg weight with roof access, lifting, clamp zones, rail span, portrait/landscape permission and installation productivity.
Project loading
Obtain model-specific load and clamp-zone evidence, then complete site wind/snow, roof or ground structure, fastener and foundation calculations.
Rear-side modeling
Confirm rear construction and use project albedo, height, row spacing, shading and mounting obstruction rather than treating 80% bifaciality as yield.
Documents and packing
Request IEC/load/fire/PID files, warranty, flash/EL, serials, 36-per-pallet/720-per-container drawing, pallet mass and shipping inspection criteria.
Format and batch boundaries
A 550 W/144-half-cell label does not establish structural or document equivalence
The exact BOM, model revision and project mounting design remain decisive.
Cell count is not a universal format
Use the stated dimensions, weight, electrical table and suffix; do not substitute another 144-half-cell module without redesign.
STC power is not delivered energy
Field output depends on temperature, irradiance, spectrum, mismatch, soiling, rear irradiance, downtime and system losses.
MC4-compatible is not connector approval
Confirm exact mating pair, manufacturer, rating, certification, tooling and no cross-mating of incompatible connector brands.
No numeric load value is currently evidenced
Require the released batch datasheet/test and project structural calculations before roof or ground-mount approval.

Questions to close before approving the 550 W production batch
All answers must map to the exact manufacturer suffix and delivered BOM.
Can TC72N-550 be substituted with another 550 W module?
Not without review. Compare dimensions, weight, cell/BOM, voltage/current, connector/cable, loads, certifications, packing and warranty.
Are the mechanical loads confirmed?
No. The internal record refers to an approved batch datasheet but gives no numeric load. Obtain model-specific evidence and complete project structural design.
Does 1500 V determine the string length?
No. Calculate cold Voc and hot operating Vmp with the exact coefficients, inverter windows, safety factors and local code.
What belongs in production approval?
Approve datasheet/nameplate/BOM, sample, certificates, flash/EL criteria, connector/cable, pallet drawing, serial traceability, inspection and warranty documents.
Prepare a TC72N-550 batch-specific RFQ
Send inverter/string limits, mounting geometry and loads, destination certificate needs, connector/cable, packing, inspection and serial-traceability requirements.
Start with the product, application or project information you have. We can help identify the remaining configuration, document or delivery questions before a final quotation.
