Sunpok High-Voltage Rack System: Purpose-Built for High-Performance Energy Storage
In professional energy storage, the margin for error is minimal. Systems must perform predictably under load, integrate seamlessly with existing electrical infrastructure, and maintain stability over years of service. The Sunpok 76.8V 314Ah rack-mounted lithium battery is developed to meet these exacting standards. It is a high-voltage component designed for integrators and contractors who value engineering precision and long-term system reliability.
High-Voltage Efficiency for Modern Installations
The 76.8V architecture addresses the growing demand for higher voltage energy storage in both residential and light-commercial sectors. Operating at this voltage level significantly reduces the current required for power delivery, which in turn lowers resistive losses and minimizes heat buildup in cabling and connections. This efficiency gain allows for cleaner system layouts and reduces the physical footprint of the balance of plant, making it an ideal choice for space-constrained technical rooms.
Stable Chemistry in a Robust Chassis
Inside the industrial-grade enclosure, LiFePO4 cells provide a stable and predictable energy source. This chemistry is selected for its resistance to thermal stress and its ability to maintain performance consistency across numerous cycles. The rack-mountable chassis is constructed for durability and ease of handling during installation. With an IP21 rating, the unit is protected against solid foreign objects and vertically falling water, confining its use to controlled indoor environments such as dedicated battery rooms, IT closets, or protected equipment shelters.
Integrated Management and Communication
System health and safety are managed by a sophisticated Battery Management System (BMS). This internal controller continuously monitors cell voltages and temperatures, executing cell balancing to ensure uniformity across the battery pack. Communication is handled via CAN and RS485 protocols, enabling the battery to act as an intelligent node within a larger energy management ecosystem. This allows for precise coordination with compatible inverters, ensuring that charging and discharging events are optimized for both performance and longevity.
A Component for Professional Integration
This battery is strictly a component for professional assembly. Sunpok does not provide installation services, and the product is not designed for consumer-grade "plug-and-play" deployment. Proper integration requires the expertise of licensed electricians or system integrators who understand high-voltage DC systems. They are responsible for implementing the necessary safety mechanisms, including fusing, disconnects, and grounding, to ensure the installation complies with local codes and operates safely.
Manufacturing Excellence and Supply Chain Support
As a direct manufacturer, Sunpok leverages its Guangzhou-based production facilities to maintain strict quality control over every unit. We focus on serving the B2B market, offering OEM and ODM services to meet specific project requirements. Each battery undergoes comprehensive factory testing before shipment. Our logistics capabilities support global distribution through flexible Incoterms, ensuring that projects of any scale receive reliable and timely delivery.
