Inquiry desk

HelioHarbor Sourcing contact path

Send your battery energy storage system requirement through the form below. Include a work email for follow-up questions about the proposed equipment and quotation scope.

Where the brief goes

The form is the published procurement channel. Provide the buying company and a work email so specification questions and supplier quotation details can be discussed with your team.

What to include

Equipment type, usable capacity, rated power, quantity, US destination, and the delivery window. Write figures with units, such as 500 kWh and 250 kW, plus the enclosure rating and the document list you want checked.

Review order

The desk reads specification first, then quantity and destination, then documents and commercial scope. A missing line is returned as a question. It is not filled with an assumption.

Before you submit

  1. Name the application and whether the path is AC-coupled or DC-coupled if you already know it.
  2. Put chemistry, cycle life basis, DC voltage, and thermal management in the requirement box, or mark them open.
  3. State quantity and the US destination as separate facts from the technical lines.
  4. If you add a budget, include currency and per-system, per-kWh, or whole-order basis.
  5. High-end, mid-range, budget, or undecided is a preference, not a factory score.

HelioHarbor Sourcing is an independent sourcing partner. Submitting the form does not reserve equipment and does not appoint a manufacturer. You can also review inquiry names or the compact brief before you write. The ratings note explains the same fields at more length.

Keep commissioning, fire review, and interconnection on your own project list. The form can mention that those approvals are still open. The desk will not close them. Freight and accessory boundaries should be written so two quotations can be lined up later without guessing which cables were included.

If the building team is still choosing a path, say whether the study is AC-coupled storage beside an existing array or DC-coupled storage on a shared DC bus. Each path changes the inverter role and the document set. A lower unit price is useful when delivered scope matches; a higher-service proposal may include documents or accessories that another supplier excludes. Ask for those line items before deciding which proposal fits your budget.

Request MOQ, paid sample or pilot availability, and manufacturing and shipping milestones when those affect the buying decision. Identify who will review the exact model's datasheet, drawing, enclosure rating and test basis. If optional budget controls are unavailable, write the amount, currency, basis and supplier preference directly in the procurement requirement.
