What are the key technical specifications of the VTCBATT ESS Rackmount Battery?
The VTCBATT ESS Rackmount Battery uses LiFePO4 cells arranged in a 16S1P configuration within a single battery pack. The nominal voltage is 51.2V, and the pack capacities range from 50Ah to 200Ah. These battery packs support a peak output current of 100A and operate within a voltage range of 40–58.4V. For larger energy storage needs, up to 16 packs can be connected in parallel to expand total capacity. The battery is designed for a lifespan of over 10 years and provides over 6000 cycles at 80% depth of discharge (0.2C). It features compact dimensions, advanced internal cooling, and supports RS232/RS485/CAN communication protocols, compatible with mainstream inverter brands.
VTCBATT’s Rackmount battery is engineered with safety as a top priority. It complies with internationally recognized certifications including CE, EN62619, UN38.3, and ROHS, ensuring it meets strict standards for quality, environmental safety, and transport. The battery features an advanced Battery Management System (BMS) that provides multiple layers of protection, including safeguards against overcharge, over-discharge, overcurrent, short circuits, and extreme temperatures. These comprehensive protections work together to ensure safe, stable, and reliable operation in a wide range of environments and applications, giving you peace of mind every time you use the battery.
The battery is designed to operate safely within a wide temperature range from -20℃ to 60℃, ensuring reliable performance even in challenging environments. However, for optimal efficiency and to maximize battery lifespan, the recommended operating temperature range is 0℃ to 35℃. When it comes to storage, maintaining the battery at temperatures between 10℃ and 50℃ helps preserve its health and performance over time. Proper temperature management during both use and storage is key to getting the best long-term value from your battery system.
Yes, VTCBATT batteries support multiple communication interfaces such as RS232, RS485, and CAN, enabling seamless integration with advanced Battery Management Systems (BMS). This allows for real-time remote monitoring and management through a dedicated mobile app or desktop platform. Users can conveniently check vital battery information such as state of charge, voltage, current, temperature, and overall health from anywhere at any time. The app also provides diagnostic alerts and maintenance reminders, helping you quickly identify and address potential issues before they become serious. This remote monitoring capability ensures optimal battery performance, extends service life, and makes maintenance more efficient and proactive—perfect for fleet managers, residential users, or commercial operators who want peace of mind and control over their energy systems.
his battery is compatible with all major mainstream inverter brands commonly used in residential, commercial, and industrial energy storage systems. Thanks to its flexible communication interfaces (such as RS232, RS485, and CAN) and standardized voltage profiles, it easily integrates with popular inverters from brands like SMA, SolarEdge, OutBack, Schneider Electric, Victron Energy, Growatt, and more. This broad compatibility allows you to design and deploy energy storage solutions with confidence, knowing the battery will work smoothly with your existing or planned inverter setup.
The battery delivers an impressive cycle life of over 6000 charge-discharge cycles when used at an 80% Depth of Discharge (DoD) and a discharge rate of 0.2C. This long lifespan is achieved through the use of high-quality LiFePO₄ cells known for their thermal stability and durability, combined with an advanced Battery Management System (BMS). The BMS continuously monitors and balances each cell, protecting against overcharge, over-discharge, overcurrent, and temperature extremes. This careful management prevents premature degradation, maintains stable operation, and ensures the battery provides reliable performance for many years, offering excellent long-term value and peace of mind.
