Pylontech US3000D LiFePO4

The US3000D from Pylontech (MPN: US3000D) is a low-voltage battery module featuring LiFePO4 technology. This modular energy storage system has a rated capacity of 3.55 kWh and a rated voltage of 48 V. The battery is designed for stationary energy storage systems and can be expanded in parallel within a battery group of up to 16 modules. An integrated battery management system (BMS), CAN and RS485 communication, and the compact design for 19-inch rack systems support integration into scalable storage solutions.

Scalable 48 V battery storage system with integrated BMS

• 3.55 kWh rated capacity and 3.3 kWh usable capacity
• 48 V nominal voltage for low-voltage storage systems
• Lithium iron phosphate (LiFePO4) technology
• 95% depth of discharge (DoD)
• Soft start to limit inrush current
• Expandable to up to 16 battery modules per battery group
• Integrated battery management system (BMS) for monitoring and protecting the storage system
• CAN and RS485 interfaces for communication with compatible system components
• More than 8,000 cycles at 25 °C
• Natural cooling without active fans
• Status and state-of-charge display via LEDs
• 7-year manufacturer’s warranty—you can find information on the warranty terms here

Modular design for various storage capacities

Individual modules can be connected in parallel, allowing the storage capacity to be adapted to specific energy needs. Up to 16 modules are possible within a single battery group. For larger systems, multi-group operation is also possible. Parallel connection is particularly useful when an existing storage system needs to be expanded later. A new battery module can be easily added to an existing system. However, before expanding the system, the state of charge of the batteries must be balanced. Important note: The previous version, the US3000C, can also be combined with other modules. However, the newest battery must always be designated as the master.

Integrated BMS for Monitoring and Protection

A battery management system (BMS) is integrated into the battery. The BMS monitors key operating conditions and provides protection against overvoltage and undervoltage during charging and discharging, overcurrent during charging and discharging, high or low cell temperatures, and short circuits. Additionally, the described functions include calculating available capacity, monitoring the electrical circuit, and communicating with the inverter. The LEDs on the front panel allow you to view the operating status, alarm conditions, and the current state of charge (SOC) directly on the battery module.

Pylontech Brackets

The Pylontech Brackets are designed for vertically stacking Pylon US3000D battery modules. With these stackable brackets, you can stack the Pylontech US3000D batteries to ensure optimal air circulation around them. The batteries should not be stacked directly on top of one another without spacing. A clamping mechanism on the sides of the bracket allows stacked brackets to be connected and secured to one another. A maximum of 4 batteries can be stacked on top of one another in this manner. One set, consisting of two brackets, is required per Pylontech battery.

Features

• Optimal air circulation
• Connect and secure stacked brackets using a clamping mechanism
• Up to four batteries can be stacked
• Set of two brackets per battery

Connection Kit

The Pylontech battery connection cable set (MPN BW0US3000BAL0002) includes two 2-meter cables (positive/negative), each with a cross-sectional area of 25 mm², and a CAN data cable with RJ45 connectors on both ends. This set is required to connect Pylontech batteries to an inverter.

Contents

• 2-meter positive cable with M8 ring terminal and Amphenol connector (Pylontech)
