1OVERVIEW

Thank you for choosing the 48V/9.6KWh lithium battery system. The battery system is based on a lithium ferrite phosphate

chemistry and adopts a modular parallel design. Main features are:

•Mainly consists of one cabinet and multiple battery modules.

•The single cabinet supports up to four 48V/50Ah battery modules in parallel.

•Supports up to two cabinets in parallel and can be expanded to 19.2KWh.

•Customized battery management system (BMS), real-time data acquisition, status monitoring and control to ensure safe and

reliable operation of the system.

The system allows flexibility in configuration, which can be widely

applied to household energy storage scenarios.

Architecture of the battery system is shown on the diagram here.

One battery cabinet can house up to 4 battery modules. Two battery

cabinets can house up to 8 modules, and so on.

Battery modules inside each cabinet are connected in parallel. CAN

BUS communication is made between the modules.

RS485 communication is provided for remote monitoring of the

battery modules by an external energy management system.

( ------- Dotted line means optional)

This manual focuses on the safe operation of the system. Please read

this manual carefully before proceeding. If you encounter any problems during the operation of the device, please consult the

corresponding instructions to solve most problems in the installation and operation. Contact your dealer or supplier if necessary.

2SAFETY PRECAUTIONS

DANGER

ATTENTION

•Wiring work must be performed by electrical engineers, otherwise

there is danger of electric shock or damage to the system.

•Before wiring, make sure that the power is off, otherwise there is

danger of electric shock or fire.

•The installed cable must meet the requirements, and the power

distribution part must comply with the safety regulations.

•Installation must be carried out in strict accordance with the

following installation steps, otherwise it will cause product damage.

•During normal operation, it is strictly forbidden to directly touch the

terminals such as output and input to avoid electric shock hazard.

•Do not open the casing of the machine directly during normal

operation, otherwise it may cause electric shock.

•When removing the outer casing, be sure to disconnect the input

and output circuits, otherwise there is danger of electric shock.

•Even if the casing is disassembled, there is still residual power

inside the machine. Do not touch the bare part of the line directly to

avoid electric shock.

•Maintenance and overhaul must be performed by professional

maintenance personnel. Users should not disassemble the machine

to avoid electric shock and product damage

•During the carry process, avoid strong vibration, falling, bumping,

and prohibit the box from being inverted. Do not lose the

accessories and user manual, warranty card, etc. when unpacking.

•It is forbidden to modify the system by itself to avoid serious

accidents.

•When an abnormality occurs inside the machine, immediately

disconnect the power supply and load.

•If the product is found to be damaged or missing

parts, it cannot be installed, otherwise it may

malfunction. If the packing list does not match

the physical name, please do not install and

contact the dealer in time.

•When handling and installing, please lift it gently

to avoid injury to the foot or damage to the

product.

•Keep the system away from flammable objects

and away from heat sources.

•Do not drop debris into the system when

installing this system, otherwise it may cause

system failure.

•Before running, please ensure that the product

is used within the allowable working range,

otherwise it will cause damage to the product.

•When the product is not used for a long time,

the battery should be discharged to between

45% and 60% of the battery, and the battery

output should be disconnected to avoid the

battery being emptied.

•Be careful when handling, so as not to hurt your

body.
