2 Safety

2.1 Safety Precautions

Before carrying out battery work, you must read carefully the safety precautions

and master the correct installation and connection methods of the battery.

Prohibit to turn it upside down, tilt, or collide.

Prohibit to short-circuit the positive and negative poles of the battery,

otherwise it will cause the battery to be damaged.

Prohibit to throw the battery pack into a fire source.

Prohibit to modify the battery, and it is strictly prohibited to immerse the

battery in water or other liquids.

DO NOT place installation tools on the battery during battery installation.

DO NOT disassemble, squeeze, bend, deform, puncture, or shred the

battery without the authorization of supplier and authorized dealers.

DO NOT exceed the temperature range, otherwise it will affect the battery

performance and safety.

The battery circuit must be kept disconnecting status during installation

and maintenance operations.

Check the battery connection end bolts regularly to confirm that the bolts

are tight.

2.2 Abuse Operation

The battery pack needs to avoid abuse operations under the following (includ-

ing but not limited to) conditions:

Abuse Operation

Protection Description

Reverse connection of positive

and negative poles

If the positive and negative poles are connected reversely, the

battery will be directly damaged.

External short circuit

If the battery pack is short circuited externally, the battery will

be directly damaged.

Series connection application

The battery pack does not support the application of battery

packs in series. If the battery packs are forced to be

connected in series, the batteries may be directly damaged,

and may even cause fire, explosion and other dangers.

3 Overview

3.1 Product Description

The B20L48V100/B20L51V100 ESS series products use lithium iron

phosphate (LFP) as the positive electrode material. It can be widely used in

energy storage systems such as residential energy storage, back-up power, and

PV self-consumption optimization.

The battery pack is composed of 15 cells/16 cells of LFP batteries in series

connection, with low self-discharge, high energy density, and no memory effect. This

type of battery also has excellent performance in high rate, long cycle life, wide

temperature range, and high safety.

3.1.1 Features

High energy density

Higher volume ratio energy and weight ratio energy.

Maintenance-free

The battery pack is maintenance-free in the process of using, which can save

customers' battery operation, maintenance testing costs and reduce the frequency of

on-site replacement.

Long cycle life

The battery pack life is 3 times long than the ordinary lead-acid batteries.

3.1.2 Basic Functions

Monitor

The battery system uses a high-performance BMS, it has protection functions

such as over current, over voltage, high and low temperature, etc.

Alarm

Support abnormal alarms such as over voltage, undervoltage, over current,

short circuit, high and low temperature, battery failure, hardware failure, etc.

Communication

Provide dual RJ45 interfaces, upload alarming and status data through the

RS485/ CAN communication protocol.

Balance function

Support the cells balance function.

3 Overview

3.2 Application Scenario

The battery pack is used to provide backup power, load shifting, peaking

shaving and can be used for residential energy storage, solar energy storage and

other application scenarios.

If there is a monitoring platform or APP of the customer's terminal

Charger/Inverter for battery configuration, then the battery status and data can be

easily monitored through the inverter's monitoring platform or APP.

The normal working operation diagram of the battery pack can be as shown in

the figure below.

4 Application Description

4.1 Low-temperature Application

Low-temperature charging

The battery pack does not support direct charging of the battery below 0°C.

When the minimum temperature of the battery is below 0°C, the BMS will cut-off

the charging circuit and cannot be charged.

Low-temperature discharging

The battery pack does not support discharge below -20°C. When the

minimum temperature of battery is below -20°C, the BMS will cut-off the

discharge circuit and cannot discharge.

4.2 Low Battery-capacity Storage (SOC≤5%)

After the battery pack is powered off, there will be BMS static power

consumption and self-discharge loss. In actual scenarios, it is necessary to avoid low-

battery-power state（SOC≤5%）storage. If it is unavoidable, the longest storage

period is 30 days@25°C, 15 days@45°C. The battery needs to be recharged in time

after storage, otherwise the battery may be damaged due to over-discharge, and the

entire battery pack needs to be replaced.

The following conditions may cause the battery pack to be stored in a discharged

state:

After the utility power failure, the line/fault cannot be eliminated in time, and

the power supply cannot be restored for a long time.

After the installation and commissioning work is completed, the utility power

is turned off directly, but the battery pack is not powered off, which will cause the

battery to enter the low power consumption mode.

Other reasons cause the battery pack to fail to enter low power consumption

normally.

4.3 Application of Nearing the Ocean

The atmospheric corrosion environment is defined and classified according to

the natural environment state, and the A/B environment is defined as follows:

A. environment refers to the ocean or the land near the pollution source, or

the environment with simple shelter (such as awning. "Near the ocean" refers to the

area 0.5～3.7km away from the ocean; "Near the pollution source" refers to the area

within the following radius: 3.7km from the saltwater lake, 3km from heavy pollution

sources such as smelters, coal mines, and thermal power plants, chemical industry,

rubber, electroplating, etc. 2km from medium pollution sources such as chemical

4 Application Description

industry, rubber and electroplating, etc. And 1km from light pollution sources such

as food, leather and heating boilers, etc.

B. environment. Refers to the environment on land or outside with simple

shelter (such as awning within 500m from the coast, or the environment on the sea.

NOTE

The battery pack can be used under other environmental conditions

and cannot be used alone under A/B environment. If it is to be used in the A/B

environment, it needs to be equipped with a high-protection air-conditioning

cabinet, which is recommended to be IP55 or higher.

4.4 Installation Location Requirements

• Please install the battery pack indoor.

• The area is completely waterproof.

• There are no flammable or explosive materials.

• The distance from heat source is more than 2 meters.

• The distance from air outlet of inverter is more than 0.5 meters.

• The minimum clearance to battery pack is more than 5mm, rack, cabinet or any

object is more than 0.5 meters.

• The installation areas shall avoid of direct sunlight.

• There is no mandatory ventilation requirements for battery pack, but please avoid

of installation in confined area. The aeration shall avoid of high salinity, humidity

or temperature.

• Batteries are not allowed to be installed in the habitable space of the residence.

4.5 Recycling and Disposal

Failed batteries contain varieties of heavy metals, corrosive organic solvent, carbon

and other harmful materials, and if they are threw away arbitrarily, it is too harmful to

the environment and public health.

Failed batteries need to be recycled and disposed of according to local policies.

Supplier can provide the recycling guideline about the lithium battery, which can help

the end user to guide how to recycle and dispose the lithium battery.
