4 Product Overview
4.1 Brief Introduction
Product overview
SOFAR GTX5000S is a battery system with an operating voltage range
between 40. 8~57. 6V. It is utilized in household energy storage
applications and works together with a low-voltage PCS to realize the
goal of energy storage for the home.
SOFAR GTX5000S has built-in BMS (battery management system),
which can manage and monitor cells information including voltage,
current and temperature. What’s more, BMS can balance cells
charging to extend cycle life. BMS has protection functions including
over-discharge, over-charge, over-current and high/low temperature;
the system can automatically manage charge state, discharge state
and balance state.
Multiple batteries can connected in parallel to expand capacity and
power for larger capacity and longer power supporting duration
requirements, SOFAR GTX5000S support up to 4 parallel operation.

4.3.1 Wiring instructions
Applicable to CEC requirements in Australia only.
Note:
1. Power Switch larger than 125A;
2. You are advised to use the EV power cable with size min. 25 mm2 or
3AWG (600V, 125A) and length min. 1500mm. The length of the power
cable from connecter terminals of each battery pack to the battery
connecter interface of PCS should be same by isolated device.
3. Before assembling Power cable, label the cable polarities correctly
to ensure correct cable connections.
4. The power cable installation and connected must training skilled of
professional personal.

Suggest Wiring Diagram (except CEC):
1、Power cable wiring instructions
Power cable terminals: There are two pair of power terminals, each
pair with same function.
Single module: Any of the terminals of each pair can be used.
Parallel system: Multiple batteries can connected in parallel to expand
capacity and power for larger capacity and longer power supporting
duration requirements.
NOTE: P+ must connect to master pack, and P- must connect to last
slave pack.
Master pack: one of the P+ terminals connect to PCS, the other one
paralleling to another battery for capacity expanding.
Last slave pack: one of the P- terminals connect to equipment, the
other one paralleling to another battery for capacity expanding.
Other slave pack: for each pair terminals, paralleling to another
battery for capacity expanding.
2、Parallel communication cable wiring instructions
CAN/Link In and Link Out communication terminal (RJ45 port) is
integrated with the signal for automatic coding function, it's can

GTX5000S USER MANUAL

automatic identification the parallel connected slave batteries by
internal control software of master battery.
NOTE: The connection order of Port In and Port Out should not be
wrong, otherwise it will lead to the automatic coding failed.
It is required that the Port In of the master PACK should be connected
to the PCS, and the parallel communication wire is connected to the
Port In of the first slave PACK from the Port Out of the master PACK.
Then the Port Out of the first slave PACK is connected to the Port In of
the second slave PACK. The Port Out of the second slave PACK is then
connected to the Port In of the third slave PACK. The parallel system
support up to 4 parallel operation, and Port Out of the last slave PACK
do not connected to the communication line.
3、PCS communication cable wiring instructions
The OUT communication port of the Master pack is connected to PCS.
4、Grounding wiring instructions
The ground wire of the battery system needs to be connected reliably.
Connect the grounding of the parallel system first, and then ground it
nearby through the connection point of one of the battery packs.
4.3.2 Link Port and Automatic Coding Function
CAN/Link In and Link Out Communication follow CAN protocol, for
communication between multiple parallel batteries.
After confirming the wiring is correct(refer to section 4. 3. 1), press the
startup button of the master pack long.
After normal startup, the parallel battery system will automatically
code and assign ID to each parallel PACK, and then the parallel
system will run normally(refer to section 4. 2. 1).

4.3.3 Link Port
CAN Communication Terminal(RJ45 port) follow CAN protocol,
connect to communication port.
1. BMS controls the charging current/charging voltage or discharge
current/discharge cut-off voltage of the PCS through CAN com-
munication according to the battery voltage and battery temperature.
2. If the battery capacity is less than 8%, BMS controls the PCS to make
compulsory recharge through the CAN communication to avoid the
damage of the battery due to deep discharge.
3. If SOC was less than 97% for one consecutive month, BMS
controlled PCS by CAN communication to full charge the battery to
corrected SOC and fully charged capacity.
Note: Through the SOFAR PCS, skilled peoples can set the fully
charged time period.
