48V 51.2V 100Ah 200Ah 300Ah 400Ah Options From 5kWh to 20kWh Lithium Lifepo4 Back Batteries Units

Home Energy Storage System

Engineered around premium Grade-A EV-standard LiFePO₄ cells, this battery module integrates an automotive-grade intelligent BMS with a precision solid-state circuit-breaker system for triple-layer protection—thermal, electrical, and mechanical. Designed for universal interoperability, it speaks the same protocols as the industry’s most popular hybrid and off-grid inverters (CAN, RS-485, Modbus-RTU) and can be soft-configured from 51.2 V to 48 V nominal at the press of a key. Scalability is built-in: up to eight identical units can be paralleled without additional combiner boxes, delivering a seamless 5 kWh to 40 kWh expansion path while maintaining ±2 % cell-level balancing accuracy and <100 ms fault isolation across the entire array.
