One clean supply chain.
New energy manufacturing from one network: energy storage with 10ms transfer and 10,000-cycle depth, 2GW+ solar module capacity, and EV charging systems from 30 to 360kW — boards, wire harnesses, cabinets and certification files together, signed by the same engineering desk.
Energy systems, one clean supply chain.
Energy equipment fails on the gaps between vendors: the BMS board from one factory, the module built somewhere else, cables and cabinet from two more — and the certification stack you assemble alone. Our network closes those gaps: battery modules with BMS SMT, laser welding and pack aging, wire harnesses, 42-52U cabinets rated to 1,600 kg, and CE, IEC 62109, UN 38.3 and UL 2594-series files coordinated by one desk. What that actually buys you is a shorter call chain: when the module engineer asks the cabinet engineer a question, the answer takes a hallway walk, not a Monday email. It is not cheaper to do it the fragmented way — it just looks cheaper until the change orders arrive.
Product lines
Fragmented supply, quantified.
Fill in one vendor per row in a typical piecemeal energy project — then count the hand-overs.
| Point of difference | Fragmented suppliers | EMS-Trade network |
|---|---|---|
| BMS to module | Battery module, BMS board and wire harness bought from three factories and matched by eye, with three fault-finding cultures when it fails — each one arguing the other two caused it | BMS SMT, laser-welded module assembly and wire harness from one network — matched by one program owner and root-caused by one team |
| Cabinets & enclosures | Sheet-metal cabinets from a fourth vendor, toleranced against someone else's drawings, re-quoted whenever the assembly changes | In-house sheet-metal lines — 42-52U cabinets rated to 1,600 kg, doors and power-ready hardware on one schedule, one drawing set |
| Certification chain | CE, IEC and UL files scattered across four suppliers; you assemble the stack, red-line the gaps and re-run the expensive tests | CE · IEC 62109 · UN 38.3 · UL 2594/2202/2231 files coordinated from one network — pre-checked before the lab, not after it |
| Delivery & export | Cargo arrives in three consignments weeks apart; export paperwork, HS classification and customs files are your project | One consignment — FOB Shenzhen, CIF or DDP — with export docs and HS classification from the same desk that built it |
Three product lines, one warranty network.
The parameters below are what a buyer checks first: numbers first, then the paperwork. All three lines run under the same ISO 9001 quality system and the same 24-48h quote desk: three factories, one network, one liability.
| Line | Key parameters | Certification & delivery |
|---|---|---|
| Energy storage & ESS | 10ms transfer between grid and store, 10,000 cycles at 100% DOD, rack modules around the 51.2V platform — the architecture behind the group's Changsha program since 2016 | CE · IEC 62109 · UN 38.3 · shipped to 20+ countries since 2016 |
| Solar PV | 2GW+ module capacity in the network; microinverter family spanning 400-1600W; bifacial and N-type lines on their own automation | CE files with the IEC 62109 series; module lines running IEC-standard production controls |
| EV charging | DC fast chargers from 30kW to 360kW with AC wallboxes in the same product family — power stage, firmware and enclosure from the same engineering group | UL 2594 / 2202 / 2231 series files · CE · OCPP 2.0.1 charging platform |
Send the package, not the puzzle.
One BOM, one drawing set and one point of contact. The engineering desk answers within 24-48 hours with the build plan and a fixed quote — including which certificate files travel with your shipment, and which ones we would rather not sign. The second list is shorter here than anywhere else.
