Product Overview
The 76.8V120AH high voltage rack-mounted lithium battery module delivers 9216Wh of nominal energy and 8294.4Wh of usable energy in a single 468×642×202mm unit.
With a charge/discharge voltage range of 68.4–85.2V and a 120A charge/discharge current, it is designed for high voltage energy storage systems. A safety-first intelligent BMS monitors system voltage, cell voltage, cell temperature, system current and SOC, while RS485/CAN communication supports system integration.
The patented modular plug design simplifies installation and enables flexible expansion, and air cooling, a cycle life of 6000 cycles or more at 25°C and a design life of 10 years or more support long-term operation.
Certified to CE, UN38.3 and MSDS, the module suits residential solar storage, emergency backup and off-grid operation.

Mode |
Description |
|
Emergency backup |
Stored energy supplies critical loads when the main supply is interrupted. |
|
Off-grid operation |
Modules provide standalone power where no utility connection is available. |
|
Solar self-consumption |
Modules store surplus solar energy for later use at homes and buildings. |
