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

liquid extinguisher could result in the risk of explosion.

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

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 device 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.

Please charge the battery in 18 hours after it fully discharged or over-discharging

protection mode is activated.

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

DL5.0C 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

Brief Introduction

DL5.0C lithium iron phosphate battery system is a standard battery system unit,

customers can choose a certain number of DL5.0C 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 high operating temperatures, limited installation space, long power backup time and

long service life.

Product Properties

DL5.0C energy storage product’s positive electrode 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.

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~ +55oC, circulation

span and discharging performance are well under high temperature.

Less volume, lighter weight.

DIP Switch Description

When the batteries are connected in parallel, the host communicates with the slaves

through the CAN interface. The host summarizes the information of the entire

battery system and communicates with the inverter through CAN or 485.

If the master is the latest DL5.0C battery with DIP switch:

1. The communication cable from the master CAN IN to the inverter comm port

should be the correct one.

DIP Switch Description

2. When the battery works with GOODWE, Solis, LUX, Sofar, DEYE(Sunsynk),

VICTRON, IMEON, Sungrow, SMA, RENAC, DELIOS, SAJ(CAN Comm) before starting

the battery, you need to put the master DIP switch "# 3" to the "ON" position (to the

top), then turn on the batteries.

3. If the battery communicates with the Axpert-king/VMIII/MAX, Infinisolar, Growatt

SPH/SPA(CAN comm) GMDE, turn the master DIP switch "#2" to "ON" position.

4. If the battery communicates with the Growatt SPF HVM-P/ES/WPV by RS485

communication, turn the master DIP switch "#2" and "#3" to "ON".

5. If the battery communicates with the Schneider Conext Series, turn the master DIP

switch "#1" and "#3" to "ON".

6. When you setup the master DIP as setting 1~4, all the slaves keep the DIP 0000,no

need to change.

7. If the energy storage system has only one DL5.0C, it is the master itself, and still

follow the above steps.

Note: For more information of matching inverter brands, please subject to the latest
