symbol
Danger
●Battery strings will produce high voltage DC
power and can cause a lethal voltage and
electric shock.
●Only qualified person can perform the wiring
of the battery strings.
Warning
Risk of battery system damage or personal injury
●DO NOT pull out the connectors while the
system is operating!
●De-energize from all multiple power sources
and verify that there is no voltage.
Caution
Risk of battery system failure or life cycle
reduction.
Warning: This product is a high voltage DC system, operated by
authorized person only.
Danger: Before installation or operation you must read <Operation
Menu> carefully.
Caution:

1 Introduction
1.1 Brief Introduction
Tower is a high voltage battery storage system based on lithium iron phosphate battery, and it’s
one of the new energy storage products developed and produced by Dyness. it can be used to
support reliable power for various types of equipments and systems. Tower is especially suitable
for application scene of high power, limited installation space, restricted load-bearing and long
cycle life.
1.2 Product Properties
The whole module is non-toxic, non-polluting and environmentally friendly;
Anode material is made from LiFePO4 with safety performance and long cycle life;
Battery management system (BMS) has protection functions including over-discharge,
over-charge, over-current and high/low temperature;
The system can automatically manage charge and discharge state and balance current and
voltage of each cell;
Flexible configuration, multiple battery modules can be in serial for expanding voltage and
Capacity.
Adopted self-cooling mode rapidly reduced system entire noise;
The module has less self-consumption, up to 6 months without charging; no memory effect,
excellent performance of shallow charge and discharge;
Working temperature range is from 0 to 50 ℃, with excellent discharge performance and
cycle life;
Small size and light weight, standard module is comfortable for installation and
maintenance;
