FORTRESS LITHIUM BATTERY INSTALLATION MANUAL LFP-5 

SECURE YOUR ENERGY WITH FORTRESS LITHIUM BATTERY SYSTEMS 

Fortress battery systems utilize the industry’s most environmentally benign chemistry- Lithium Ferro 
Phosphate, which eliminates operating temperature constraints, toxic coolants and the risk of thermal 
runaway and fire. The built-in smart Battery Management System (BMS) integrates multilevel safety 
concepts: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation. 

Fortress High-performance Lithium Batteries are manufactured at the highest quality standard. It comes 
with  large  power  capacity  and  a  fast  charging  and  continuous  discharge  power.  The  proprietary 
architecture and BMS eliminate the need for cooling or ventilation, which creates an efficient round-trip 
conversion. 

Fortress Lithium Battery is safe, easy to install, consistently reliable, highly efficient. It provides you the 
lowest lifetime energy cost.   

This installation manual contains information concerning important procedures and features of Fortress 
Power  Lithium  batteries.  Read  all  the  instructions  in  this  manual  before  installation,  operation, 
transportation, storage and maintenance.
