Overview

The LB series is a LiFePO4 energy storage battery in a high-strength metal shell, designed for residential and small commercial PV storage systems on 25.6V and 51.2V platforms from 2.56 to 16.08 kWh.

A built-in MCU with intelligent power management monitors battery status in real time — SOC/SOH estimation, cell balancing and multiple sleep and wake-up modes — while RS232/RS485/CAN communication with user-changeable inverter protocols integrates with mainstream inverters. Up to 15 modules can operate in parallel as storage needs grow.

Key Features

  • True-capacity LiFePO4 battery in a high-strength metal shell
  • SOC & SOH estimation, real-time status monitoring
  • LED strip + LCD display
  • Ultra-low standby loss with multiple sleep/wake-up modes
  • Adjustable over-current protection, short-circuit protection, buzzer alarm
  • High measurement accuracy: voltage ≤20mV, current ≤2% FS, temperature ≤2°C
  • Up to 15 modules in parallel — RS485 host monitoring & CAN
  • Cell balancing; capacity & cycle-count calculation
  • User-changeable inverter communication protocols
