3.4 Module parallel solution
4850 the energy storage module can be used in parallel and the maximum
number of parallel units is 6.
Parallel installation steps:
1.the Master and the slave CAN communication have been connected.
2.8 core shielded twisted pair is used to connect host TX to slave 1 RX,
slave1 TX to slave2 RX,and so on, to complete communication connection.GND
must connected.
3.OUT+ and OUT- are connected to the confluence box through the cable,
and the confluence box is connected with the inverter.
4.Configure the master slave address through CAN debugging software, see
the following table.

4．Safety precautions
Safety precautions
It must be operated by professional electrical personnel or trained
technicians.
Ensure that the power switch is disconnected during installation.
Please check the material carefully before installation. If there is any
missing or damaged, please do not install dangerous.
The installation position requires waterproof, moisture proof and good
heat dissipation.
When installing, you must wear insulating gloves. Please do not carry
large or too long metal ornaments. The metal tools need to be wrapped
with insulation tools to avoid short circuit risk.
When installing, it is forbidden to contact the total and negative load
of the battery pack at the same time, so as to avoid high voltage hurting
people.
When installing, do not drop debris into the module, otherwise it may
cause instability or damage to the system. It is forbidden to shake the
battery module in the shell, prevent the internal resistance of the wire
loosening, increase the temperature, and cause the battery collision
risk.
All modules must be connected correctly before they can be electrical
tested, and the plug is not allowed when power on. Otherwise, there will
be risks of electric shock or burnout of modules.
Non-professional personnel are forbidden to disassemble the module shell,
and not to touch the internal circuit boards, so as to avoid causing
electric shock accidents.
It has not been confirmed by the manufacturer's technical personnel that
the system is not allowed to be modified or used in other projects, so
as to avoid serious accidents.
