OEM / ODM

We work with distributors and brands that need their own product line, not generic relabeling. If your team already has a target market and sales channel, we can build around that commercial reality. Documentation expectations for serious orders are summarized on Trust & Quality.

Typical commercial bands

These are experience ranges for planning—not a promise until your SKU is quoted. Your signed PI or contract overrides this page.

MOQ
Quoted per SKU and design complexity. Catalog-style packs often start at modest volumes; deep mechanical or BMS changes push the entry quantity up. We give a number only after drawing review.
Sample lead time
Roughly 2–6 weeks from agreed drawing freeze for many pack programs. New housing tooling, special tests, or holiday factory blocks can add time—we state the calendar in the sample PO.
Mass production lead time
Roughly 4–10 weeks from deposit, material lock, and released BOM for typical runs. Large container orders or tight cell allocation windows can stretch this; your quotation will show the band we can commit to.
NRE and tooling
Fixtures, molds, certification samples, and third-party lab slots are billed or quoted separately when they apply. Nothing hidden—we list them before you pay a sample invoice.

Typical cooperation workflow

Step 1 · NDA and requirement intake

You share target market, inverter ecosystem, volume plan, and compliance scope. We confirm feasibility and data needed for quoting.

Step 2 · Technical freeze and sample

Mechanical layout, electrical limits, and labeling files are frozen. Sample schedule and validation criteria are agreed in writing.

Step 3 · Pilot and mass release

After sample sign-off, we run pilot lots, lock QC checkpoints, then release volume production with shipment documentation.

Before we quote

Please prepare expected annual volume, target country, required certificates, and your launch timeline. That lets us give you a realistic MOQ and lead-time range from the start.
