About DEJIE TECH
Shenzhen Dejie Electronic Technology Development Co., Ltd. (DEJIE TECH) is a power electronics company focused on new energy — carrying out product development, manufacturing and sales across solar PV, energy storage, industrial power supplies and high-power EV charging.
Getting power conversion right
The efficiency, reliability and cost of a new energy system depend largely on the power conversion stage. We develop power modules, thermal management, mechanical design and control strategy within a single engineering framework, so core building blocks and finished systems are matched by design — not assembled from bought-in parts.
Our customers are EPC contractors, system integrators, charge point operators, equipment manufacturers and project owners. We supply individual units and also adapt capacity, interfaces and protocols to project requirements. From selection discussions to serial delivery, milestones and documentation are confirmed item by item.
- ✓Four product lines covering generation, storage, conversion and charging
- ✓Core power stages co-developed with complete systems
- ✓Project-based configuration and packaged delivery
What we actually do
Being specific about scope is more useful than piling up adjectives.
Engineering & selection
Topology and model recommendations based on voltage class, capacity, efficiency and ingress requirements, delivered with parameter tables and configuration lists.
Manufacturing
Power module and system assembly, burn-in and functional testing executed by batch, with traceable shipment documentation and serial numbers.
Quality & documentation
Datasheets, test records and certification documents provided on request. Final parameters follow the signed technical agreement.
Delivery & after-sales
Packing, shipping documents, commissioning guidance and technical support tracked against order milestones, with on-site coordination where required.
Standards and compliance support
Certification, grid connection and charging protocol requirements differ by market and project. We align the list at design stage.
Power conversion equipment
Testing and documentation requirements corresponding to IEC 62109, IEC 61727 and IEC 62116 can be addressed on a project basis.
Storage systems and cells
Cell and system safety testing, transport documentation (e.g. UN38.3) and fire suppression scheme descriptions can be coordinated per project.
Charging equipment
Vehicle communication is compatible with GB/T 27930 (legacy and current); protocol conformance and interoperability testing can be supported.
