HelioLink Sourcing desk boundary

What the desk will ask a factory

Each outbound note names the buyer application, the quantity and the US destination. It then lists the evidence the factory should return for the exact proposed item.

• Model identity, usable capacity and rated power on the same row.
• DC voltage, current limits and the connector or terminal style.
• Thermal management description and enclosure rating.
• Communication path, including whether an external controller is assumed.
• Document set: datasheet, drawing, and any listing or transport file the supplier is willing to share for that item.

What stays outside the desk

These limits are part of the service description, not a footnote. They keep a sourcing note from being read as a design stamp.

1. No claim that a cabinet is in a warehouse or reserved for a project.
2. Product listing and UN 38.3 transport evidence must identify the proposed item. An ISO 9001 certificate instead identifies the supplier organization, certified scope and validity; it does not approve a battery model.
3. No interconnection, structural or fire approval. Those reviewers remain with the project.
4. No published savings figure. Delivered cost is compared only after scope, freight and documents match.
5. No supplier tier assigned by this site. High-end, mid-range, budget-friendly or undecided is copied from the buyer note as a preference.

The quote desk shows the field order. The procurement brief shows one worked checklist. Neither page is a factory audit report.

The desk will forward a buyer figure such as 800 kWh usable capacity or 250 kW rated power without treating it as a measured site result. Thermal management, enclosure rating and the battery management system protocol are question labels. They become supplier statements only after the quoted model returns a file.

A lower unit price can fit a limited equipment budget when the required scope matches. A wider delivered offer may include cables, freight or document work that the cheaper offer excludes. Keep both totals and exclusions visible; the buyer decides which scope fits the project rather than treating a supplier preference as a verified grade.
