Safety Precautions
Warning
Please do not put the battery into water or fire, in case of explosion or any other situation
that might endanger your life.
Please connect wires properly while installation, do not reverse connect.
To avoid short circuit, please do not connect positive and negative poles with conductor on
the same device.
Please avoid any form of damage to the battery, especially stab, hit, trample or strike.
Please shut off the power completely when removing the device or reconnecting wires
during the daily use or it could cause the danger of electric shock.
Please use extinguisher to put out the flame when encountering a fire hazard.
For your safety, please do not arbitrarily dismantle any component in any circumstances.
The maintenance must be implemented by authorized technical personnel or our company’s
technical support. Device breakdown due to unauthorized operation will not be covered
under warranty.
Caution
Our product has been strictly inspected before shipment. Please contact us if you find any
abnormal phenomena such as device outer case bulging.
The product shall be grounded properly before use in order to ensure your safety.
To assure the proper use please make sure parameters among the relevant are compatible
and matched.
Please do not mixed-use batteries from different manufacturers, different types and models,
as well as old and new together.
Ambient and storage method could impact the product life span, please comply with the
operation environment instruction to ensure device works in proper condition.
For long-term storage, the battery should be recharged once every 6 months, and the
amount of electric charge shall exceed 80% of the rated capacity.
Formula of theoretical standby time: T=C/I (T is standby time, C is the battery capacity, I is
total current of all loads).

Preface
Manual declaration
AE-48100 Lithium-iron phosphate battery energy storage system can provide energy storage for
photovoltaic power generation users through parallel combination. Our product can store extra
electricity into battery from photovoltaic power generation system in daytime and supply stable
power to user’s equipment as power backup at nighttime or any time when needed. It can
improve the efficiency of photovoltaic power generation and increase the electric power
efficiency by peak load shifting.
This user manual details the basic structure parameters, basic procedures and methods of
installation and operation and maintenance of the equipment.

1 Introduction
1.1 Brief Introduction
AE-48100 Lithium-iron phosphate battery system is a standard battery system unit, customers
can choose a certain number of AE-48100 according to their needs, by connecting parallel to
form a larger capacity battery pack, to meet the user’s long-term power supply needs. The
product is especially suitable for energy storage applications with limited installation space, long
power backup time and long service life.
1.2 Product Properties
AE-48100 energy storage product’s positive materials are lithium-iron phosphate, battery cells
are managed effectively by BMS with better performance, the system’s feature as below:
●Comply with European ROHS, Certified TUV, employ non-toxic, non-pollution environment-
friendly battery.
●Anode materials are lithium iron phosphate (LiFePO4), safer with longer life span.
●Carries battery management system with better performance, possesses protection function
like over-discharge, over-charge, over-current, abnormal temperature.
●Self-management on charging and discharging, Single core balancing function.
●Intelligent design configures integrated inspection module
●Flexible configurations allow parallel of multi battery for longer standby time.
●Natural ventilation with lower system noise.
●Less battery self-discharge, then recharging period can be up to 6 months during the storage.
●No memory effect so that battery can be charged and discharged shallowly.
●With wide range of temperature for working environment, -10℃~+50℃.
●Less volume, lighter weight.
