Sunpok High-Voltage Rack-Mounted Lithium Battery: Engineered for Demanding Energy Storage
As energy systems grow more sophisticated, the need for storage that can keep pace with higher voltages, denser configurations, and mission-critical loads has never been greater. The Sunpok 76.8V 314Ah rack-mounted high-voltage lithium battery answers that need with a purpose-built architecture designed for integrators, distributors, and project developers who require a dependable building block for larger residential and commercial solar storage systems.
A High-Voltage Platform Built Around LiFePO4 Chemistry
At the core of this battery is lithium iron phosphate (LiFePO4) technology, chosen for its thermal stability, long service life, and excellent cycle performance. The 76.8V high-voltage configuration is optimized for modern high-voltage inverters and energy management systems, enabling efficient power conversion and reduced current stress across the system. With a substantial amp-hour rating, the battery delivers the deep energy reserve required for backup power, solar self-consumption, peak shaving, and off-grid applications.
Rack-Mounted Form Factor for Flexible Deployment
The unit adopts a standardized rack-mounted design, allowing it to be installed inside battery cabinets or server-style racks in dedicated indoor spaces. This form factor saves floor area, simplifies system layout, and provides a clean, professional appearance suitable for utility rooms, commercial plant rooms, and technical closets. The rack-mounted structure also facilitates future capacity expansion, giving system designers the freedom to scale storage as energy demands grow.
IP21 Protection for Indoor Environments
The battery enclosure carries an IP21 rating, offering protection against dust ingress and dripping water from above. This makes the unit appropriate for standard indoor installation environments where the battery is sheltered from direct weather exposure. It is intended for use in controlled indoor settings rather than outdoor or harsh industrial conditions.
Intelligent Battery Management and Communication
An integrated Battery Management System (BMS) monitors cell voltage, temperature, and current in real time, providing comprehensive protection against over-charge, over-discharge, over-current, short circuit, and temperature extremes. Cell balancing is handled automatically to maintain uniformity across the pack and extend service life.
Standard communication protocols including CAN and RS485 enable seamless integration with a wide range of hybrid and off-grid inverters. This ensures that the battery can exchange data with the inverter and energy management system for coordinated charge and discharge operation, remote monitoring, and fault diagnostics.
Designed as a System Component
This high-voltage battery is supplied as a storage component intended to be configured by qualified installers. It is designed to be integrated into a broader energy storage system alongside a compatible inverter and appropriate electrical protection. Sunpok does not provide on-site installation services; instead, the product is engineered for straightforward integration by professional technicians who will ensure compliance with local electrical codes and compatibility with the selected power conversion equipment.
The battery is not a standalone plug-and-play device. It is a high-performance module meant to serve as the energy core within a custom-designed storage system, giving developers and integrators full control over system architecture.
Manufacturing Strength Behind the Product
Sunpok Energy is a Guangzhou-based manufacturer with in-house production lines, a professional R&D team, and a quality control laboratory. Since its founding in 2016, the company has grown into one of China's established producers of lithium energy storage batteries, serving customers across residential, commercial, and industrial markets. Sunpok supports OEM and ODM customization, allowing partners to specify packaging, branding, and technical parameters suited to their target markets.
Every battery undergoes rigorous factory testing prior to shipment. Bulk and customized small packaging options are available, with delivery terms including FOB, CIF, DDU, and DDP to accommodate global logistics requirements.
