Product Description

HJ51.2V-628AH – 32kWh LiFePO₄ High‑Capacity Battery | 300A Discharge, Up to 16 Parallel Units for Large Homes & Commercial Solar Storage

The HJ51.2V-628AH is a massive 32.154 kWh lithium iron phosphate battery designed for large residential solar systems, small commercial buildings, and off‑grid applications that demand high energy storage and power output. Using Grade A 3.2V 314Ah cells in a 2P16S configuration, this battery delivers 628Ah capacity at a nominal 51.2V - sufficient to power entire homes or small shops through nights, peak rates, or cloudy weather periods. With an industry‑leading 6000‑cycle life (over 15 years), it offers exceptional long‑term value. The 300A continuous charge/discharge current supports powerful inverters (≥15kW) and heavy loads. Modular and expandable (up to 16 units in parallel), this battery grows with your energy needs.

Key Advantages

Highest Energy in a Single Module - 32.1 kWh reduces parallel units needed, simplifying installation and BMS coordination
Ultra‑High Current - 300A continuous supports whole‑home backup with multi‑ton AC units, electric ovens, water heaters, and 11kW EV chargers simultaneously
Superior Safety - LiFePO₄ chemistry is intrinsically safe with no thermal runaway. Certified to IEC62619, UN38.3, and CE
Modular Scalability - Add up to 15 more units (total 16) for over 500 kWh of storage - ideal for commercial microgrids or large off‑grid estates
Smart BMS - Advanced Battery Management System provides pre‑charge, cell balancing, over‑current/voltage/temperature protection, and supports remote monitoring and firmware updates via CAN/RS485
Wide Inverter Compatibility - Works with most hybrid and off‑grid inverters that support 48V LiFePO₄ profiles
