Raw Material Procurement
JSBESS solar power begin by sourcing high-quality raw materials and components, including lithium battery cells, battery management system (BMS) chips, inverters, control boards, cooling fans, and steel or aluminum housing materials. All suppliers are evaluated to meet international certifications (such as CE, CB, IEC, or UN38.3, MSDS standards).
Battery Cell Testing and Sorting
Lithium cells are inspected for consistency in voltage, capacity, and internal resistance. Cells are then grouped and sorted to ensure uniform performance, which is critical for the long-term stability of the battery pack.
Module Assembly
Solar power battery cells are welded and assembled into modules. This includes installing busbars, current collectors, and protective insulation materials. Welding quality and connection reliability are strictly monitored to prevent safety risks.
Battery Pack Assembly
Multiple modules are integrated into a complete battery pack. The pack is equipped with temperature sensors, voltage sensors, and wiring harnesses to ensure real-time monitoring. The BMS is installed at this stage to control charging, discharging, and cell balancing.
Integration with PCS & Inverter
The battery pack is combined with the Power Conversion System (PCS) or inverter. This step allows DC electricity stored in batteries to be converted into AC electricity, suitable for residential or commercial use.
System Design & Control Integration
The energy management system (EMS) is configured to manage the flow of power between the grid, solar panels, batteries, and loads. This ensures efficiency, peak shaving, and demand response capabilities.
Cooling and Safety Systems Installation
Depending on the design, either air-cooling or liquid-cooling systems are installed. Fire suppression devices and circuit protection systems are added to meet safety standards.
Housing and Enclosure Manufacturing
The equipment housing is fabricated, often using powder-coated steel or aluminum. It is designed for waterproofing, dustproofing (IP54/IP65 standard), and thermal management.
Final Assembly and Wiring
All modules, PCS, EMS, and safety components are integrated into a complete energy storage system (ESS). Internal wiring and connections are checked against technical drawings.
Testing and Quality Control
Each unit undergoes comprehensive testing, such as electrical performance testing (capacity, efficiency, charging/discharging cycles); Safety testing (overcharge, short circuit, thermal stability); Environmental testing (humidity, vibration, temperature); Only products that pass all tests are approved for delivery.
Solar Power Packaging and Logistics
Finished equipment is packaged with shockproof and moisture-proof materials. Export packaging complies with international shipping standards for lithium battery products (UN3480/UN3481).
Certification and Documentation
Before shipment, products are accompanied by international certifications (such as CE, CB, TUV, IEC 62619/62040), user manuals, and warranty documents.
