Pylontech US5000 4.8kWh Li-Ion Solar Battery 48V

The Pylontech US5000 4.8kWh Li-Ion Solar Battery 48V (excl. brackets) is a modular 48V lithium iron phosphate (LiFePO₄) battery module designed for residential and small commercial energy storage systems, offering high usable capacity, long cycle life and flexible expansion.

Product Description

The US5000 is a rack‑ or wall‑mountable low‑voltage (48V) battery module with 4.8kWh nominal energy and 4.56kWh usable capacity at 95% depth of discharge. It is intended for use with compatible hybrid or AC‑coupled inverters in grid‑tied, backup or off‑grid systems, and can be paralleled up to 16 units on a single communication chain for larger installations.

Key Features

• High usable capacity: 4.8kWh nominal and approximately 4.56kWh usable energy per module at 95% DoD, reducing the number of modules required for a given system size.
• Modular design: Up to 16 US5000 modules can be connected in parallel on one COM string, allowing scalable storage from 4.8kWh up to around 76.8kWh without additional LV hub hardware.
• Long cycle life: >6000 cycles at 95% DoD (at 25°C), supporting a design life of 10–15+ years in typical residential use.
• High efficiency: Round‑trip efficiency greater than 95% for effective utilisation of stored PV or off‑peak energy.
• Intelligent BMS: Integrated battery management system providing cell‑level monitoring and protection for voltage, current, temperature, SoC and SoH.
• Communications: RS485 and CAN interfaces for seamless integration with supported inverter brands and energy management systems.
• Flexible installation: Suitable for 19‑inch rack mounting or wall mounting; supply here is excluding brackets, so rack or wall brackets must be ordered separately if required.
