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).
The product is affixed with a torn invalid label before leaving the factory. If anyone need to
open the cover to operate, such as set DIP mode, expand the capacity or other operations
that won’t harm the product, customer needs to contact DYNESS and inform the product ID.
DYNESS will record the case, confirm the operation can be operated and will authorize. After
the authorization, only professionals are allowed to operate. Contact the DYNESS authorized

distributor or agent to get a new torn invalid label. After the operation, re-attach the new
torn invalid label at different locations.
Preface
Manual declaration
Powercube series energy storage system is composed of several B4850 or B4874 energy storage
system units connected in parallel to provide users with energy storage power generation.
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 describes 4Box, 5Box, 6Box and 7Box in the Powercube series. It details the
basic structure, parameters, installation, and operation and maintenance of the equipment.

1 Introduction
1.1 Brief Introduction
The B4850 and B3 lithium iron phosphate battery systems are standard battery system
units. Each module can be connected in parallel to obtain a complete system of certain
specifications. Customer can select the appropriate Powercube specifications according to
their 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.
1.2 Product Properties
Powercube series energy storage product’s anode materials are lithium iron phosphate,
battery cells are managed effectively by BMS with better performance, the system feature
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 and longer system backup time.

DIP switch description:
The battery pack is connected in parallel in the Powercube, the battery module that
communication connected to the inverter is defined as the host. The host can communicate with
the slave through the CAN interface. The host summarizes the information of the entire battery
system and communicates with the inverter through CAN or 485. The connection mode is
divided into the following two cases:
Note:
Before opening the cover to change the DIP mode, contact DYNESS to inform the ID, DYNESS will
record the battery ID and authorizes the opening operation. Only authorized by Dyness to operate.
Except for changing the DIP mode, any other operations cannot be done.
