Our Featured Products

A C&I solar energy storage system is a mechanism that converts the electrical energy captured from solar panels into usable electrical energy through a inverter, and effectively stores it in an energy storage cabinet. Explore how we can leverage our expertise in these three categories of products.

C&I energy storage

Energy Storage Cabinet

IP65 energy storage cabinets are reliable for the storage of solar batteries and main devices, enabling the reduction of peak loads and filling of low demand periods, as well as support high-voltage output.


Our inverters and isolated power converters support parallel of multi items, which can meet the electricity demand of 30KW~3MW to improve the energy independence of commercial & industrial uses.

Practical, Reliable, and Scalable Energy Storage Cabinets

With an energy storage system, you can store and reuse solar energy to effectively reduce demand peaks and reduce energy costs. The point is that only with reliable energy storage cabinets can you safely reduce your energy costs in the long run.

Battery Cells

Using quality materials, advanced electrolyte, and highly stable graphite, our batteries feature a remarkable capacity and an extended lifespan. Our cells can be recharged multiple times without experiencing any degradation in performance.
battery pack

Battery Packs

After testing, aging, and capacity separation, the paired batteries are selected to produce battery packs. In addition, the internal structure of the battery pack is strong thanks to laser welding. Our battery packs are of stable quality and maintenance-free.

Battery Management System (BMS)

Through precise analysis of the status data of each cell, examination of charging and discharging patterns, and detection of any irregularities, our built-in battery management systems guarantees the optimal condition of all batteries at all times.

Energy Management System (EMS)

EMS allows for the visualization and timely alerting of energy data. It encompasses BMS, data acquisition, monitoring, and control systems, which transmit energy data from the field control station to the management control center.

Fire Safety System

The fire safety system and components that comply with international standards for electrical performance and safety ensure that our energy storage systems are safe from the risk of fire.

Thermal Management System

Multi temperature probes present in every battery module ensure precise temperature control, support high power rates, and emprove the reliability. The heat dissipation performance is enhanced through the spacious channel design, which effectively generates turbulence.
