Larger battery systemsModular design allows scaling with fewer units, but limited to 3 parallel packs per system
Use Guide

Getting It Working on Site

1

Install the pack in a clean, cool, dry, and ventilated area with ambient temperature below +60°C

2

Store the battery at 30–50% state of charge and recharge every 3 months if unused

3

Connect to solar inverter or charge source using correct polarity and cable gauge

4

Do not short circuit, reverse polarity, crush, disassemble, heat or immerse in liquid

5

Use only recommended charge current (20A) and voltage (57.6V) to avoid BMS lockout

6

Monitor BMS status via CAN2.0/RS232/RS485 interface for real-time performance
