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

(Wires for instance).

⚫Please do not stab, hit, trample or strike the battery in any other way.

⚫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 dry powder extinguisher to put out the flame when encountering a fire hazard,

liquid extinguisher could result in the risk of secondary disaster.

⚫For your safety, please do not arbitrarily dismantle any component in any circumstances

unless a specialist or an authorized one from our company, device breakdown due to

improper operation will not be covered under warranty.

Caution

⚫We have strict inspection to ensure the quality when products are shipped out, however,

please contact us if case bulging or another abnormal phenomenon.

⚫For your safety, device shall be ground connected properly before normal use.

⚫To assure the proper use please make sure parameters among the relevant device are

compatible.

⚫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 life span and product reliability, please

consider the operation environment abundantly to make sure 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.

⚫Please charge the battery in 18 hours after it discharges fully and starts over-discharging

protection.

Formula of theoretical standby time: T=C/I (T is standby time, C is battery capacity, I is total

current of all loads).

Preface

Manual declaration

The M3000 lithium iron phosphate battery energy storage system can provide energy storage

solutions for photovoltaic power generation users through parallel combination. During the day,

the excess power of photovoltaic power generation can be stored in the battery. At night or

when needed, the stored electrical energy can be used to supply power to the electrical

equipment, which can improve the efficiency of photovoltaic power generation, peak load

shifting, and emergency power backup.

This user manual details the basic structure, parameters, basic procedures and methods of

installation and operation and maintenance of the equipment.

M3000 ESS Unit User Manual

1 Introduction

1.1 Brief Introduction

M3000 lithium iron phosphate battery system is a standard battery system unit, customers

can choose a certain number of M3000 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 applications with high operating temperatures, limited

installation space, long power backup time and long service life.

1.2 Product Properties

M3000 energy storage product’s anode materials are lithium iron phosphate, battery cells

are managed effectively by BMS with better performance, the system’s features as below:

⚫Comply with European ROHS, Certified SGS, 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, with 3 remote functions

(remote-measuring, remote-communicating and remote-controlling).

⚫Flexible configurations allow parallel of multi battery for longer standby time.

⚫Self-ventilation with lower system noise.

⚫Less battery self-discharge, then recharging period can be up to 10 months during the

storage.

⚫No memory effect so that battery can be charged and discharged shallowly.

⚫With wide range of temperature for working environment, -20oC ~ +55 oC, circulation

span and discharging performance are well under high temperature.

⚫Less volume, lighter weight.

Battery voltage is higher than safe voltage, direct contact

with electric shock hazard.

Be careful with your actions and be aware of the dangers.

Read the user manual before using.

The scrapped battery cannot be put into the garbage can

and must be professionally recycled.

After the battery life is terminated, the battery can

continue to be used after it recycled by the professional

recycling organization and do not discard it at will.
