Energy storage and hybrid lines
Representative application tracks. Final inverter pairings, enclosure class, and certificates are quoted per destination and duty cycle.
Residential line. Wall-mount or stackable home battery in a utility room or garage; clean product context.Residential ESS
Wall and stack systems for backup, self-consumption, and tariff arbitrage where the grid allows export.
C&I systems. Outdoor ESS cabinet or container on a commercial site; daytime exterior.C&I battery systems
Outdoor cabinets and container blocks for factories, logistics sites, and campuses with demand-charge pressure.
Hybrid install. Roof PV with outdoor inverter and battery; rural or peri-urban setting acceptable.Weak-grid and hybrid
PV plus hybrid inverter and battery for unstable grids, diesel displacement, and priority-load backup.
OEM branding. Pack with approved label treatment; optional QC bench context.OEM / ODM packs
Mechanical, electrical, and labeling programs with sample-to-mass workflow and stated MOQ bands.
1 day
Typical first response
Serious inquiries with country, volume, and technical scope usually get a same-business-day direction when time zones align.
2–6 wk
Sample band
Common sample window after agreed drawing freeze; complex tooling or holiday shutdowns extend—your sample PI states the calendar.
4–10 wk
Volume band
Typical production window after deposit and material lock; cell allocation and SKU mix move the date—confirmed on quotation.
Manufacturing discipline
Buyers who tour or witness FAT care about traceability, test records, and pack serialization—not slogans. We align inspection scope and document drop dates before releasing metal.
Factory and production. Pack assembly, aging, or calibrated QC bench—real factory photography preferred over generic stock.Reference deployments
Headline outcomes are agreed with the customer or installer; your site economics are modeled from your own load and tariff data.
Detailed timelines, single lines, and test excerpts are shared under NDA for qualified RFQs—not full public dossiers.

Where we ship. Regional project map, shipping lane summary, or three-market photo strip—keep legible labels and avoid decorative clutter.Frequently Asked Questions
- Destination country and discharge port, target certifications, inverter brand and model if known, application (residential, C&I, weak-grid, or OEM), and either annual volume or project size. For batteries, a load list or 15-minute demand profile is more useful than a catalog photo. We reply with a configuration direction and document list; binding commercial terms sit on the formal quotation or contract.
- The exact pack depends on SKU, destination, and NDA stage—see our Trust page for a professional checklist. Summaries and artwork we show publicly are indicative only; marks on labels and shipping documents follow the PO you execute. Importer registrations, utility studies, and country-specific filings are typically outside the factory base pack unless quoted.
- Sample builds often fall in a 2–6 week window after agreed drawing freeze, while production lots commonly need roughly 4–10 weeks from deposit and material lock—both move with complexity and cell allocation. Your quotation states the band we can commit to; this FAQ is only for rough internal planning.
- MOQ is quoted per SKU and design complexity; shallow customization stays modest, deep ODM tooling raises the entry quantity. Standard practice is advance payment plus balance before shipment unless a long-term frame agreement says otherwise, and Incoterms are named explicitly on the PI (EXW, FOB, CIF, etc.). Nothing here replaces the text in your signed order.
