7.1 APX 98034-P2 (Power Module)
7.2 APX 5.0P-B1 (Battery Module)

The entire APX 5.0-30.0P-S2 high-voltage energy storage system is composed of a APX
98034-P2 (hereinafter referred to as Power Module) and multiple APX 5.0P-B1 battery
modules (hereinafter referred to as Battery Module, the maximum number of Battery
Module connected in parallel is 6).
Each Battery Module consists of 100Ah LFP battery cells and a DC-DC converter, which
boosts a power source of 51.2V up to 380V. One to six Battery Modules can be connected
in parallel to increase the capacity and power of the energy storage system.
The APX battery system powers the loads through the three-phase hybrid inverter MOD
3-10KTL3-XH (Backup version) or MID 11-30KTL3-XH whenever demanded; when solar
becomes available during daytime, solar energy powers the loads as a priority and the
surplus solar power is stored into the APX battery system.

1.3 Working Principle and Function
The APX distinguishes itself with better charging and discharging performance, higher
charging and discharging efficiency, higher flexibility in capacity expansion, more
accurate status monitoring, longer service life, and less self-discharge loss.
ŸProtection and Alarm: Generate alarms and provide protection in cases of overvoltage,
undervoltage, overcurrent, over-temperature or under-temperature.
ŸParallel connection: Support the parallel connection of one to six Battery Modules.
The APX 5.0-30.0P-S2 high voltage battery system is composed of a Power Module APX
98034-P2 and multiple Battery Modules APX 5.0P-B1 connected in parallel. It contains
electrochemical batteries, battery control units, power control units, battery
management units, power and signal terminals, and mechanical parts.
ŸMonitoring: Monitor the voltage, current and temperature of each battery module and
the battery system.
ŸSystem power-off: 12 minutes after the battery system and hybrid inverter
communication is disconnected.
ŸBattery Module balancing: intelligent power distribution, active balancing
ŸReport: Report alarms and status data to the hybrid inverter.
ŸCascading connection: Support the cascading of two APX systems.
ŸBattery cell balancing: passive battery balancing.
A single APX system can connect 1 to 6 Battery Modules in parallel to increase the
capacity and power of the battery system; at the same time, it supports the cascading of
2 APX systems. The APX system communicates with the hybrid inverter through RS485
communications. For a cascaded system, one APX system communicates with another
APX system through CAN communications. It also excels at operation stability.
When installing or using a battery system, observe the safety precautions provided in this
section. For personal safety, the operation personnel must read through this manual and
observe the safety instructions.

ŸNote 2 to entry: An electrically instructed person is a person who are
informed of the safety rules for operating electrical equipment and can
perform some operations under the supervision of skilled persons.
ØThis area is a restricted access area, which is explained below:
ŸNote 1 to entry: An electrically skilled person is a person who has
received special education and adequate training in safety rules for the
operation of the electrical installations.
ØEnsure that the PE cable is securely connected.
ŸArea accessible only to electrically skilled persons and electrically
instructed persons with the proper authorization.
ØFor a single APX battery system, the “Link-in” and “Link out” port of
the Power Module don't need to be connected as they are only used for
cascading the APX battery systems. For the cascaded system, connect
the “Link out” port of the Power Module to the “Link in” port of
another Power Module. Please pay attention to the connector color
when connecting the power cables. Stick to the color conventions -
orange to orange,blue to blue,black to black.

Step 2: Insert the communication cables into the “Link-in” and “Link out” port, and then
tighten the communication terminals clockwise.
Step 1: Insert the power cable into the corresponding port. The click sound indicates a
robust connection.
Step 3: The "Link out" port of the last battery module does not need to be connected.
Tighten the dust cover.
ØThe last battery module refers to the battery module that is the most
distant from the power module.
ØPlease pay attention to the connector color when connecting the
power line. Stick to the color conventions - orange to orange,blue to
blue,black to black.
Notice
Note:
Ensure that the PE cable is securely connected.
The battery is not allowed to be installed when the machine is running. Ensure that all
the lights indicating “RUN” of battery modules are off before installation.
4.4.2.3 Electrical wiring connection
Step 1: Insert the power cable into the corresponding port. The click sound indicates a
robust connection. The power cables are delivered with the Power Module.
Step 2: Insert the communication cable into the "INV " port and "BMU" port, and then
tighten the communication terminal clockwise. The INV communication port is used for
communication connection with the hybrid inverter, and the BMU communication port is
used for communication connection with the Battery Module by connecting to the "Link-
in" port of the Battery Module. The communication cables are delivered with the Power
Module.

ØHang the warning sign: Do not touch. Authorized personnel only.
ØPlease stand on dry insulating objects and do not wear conductive
material such as watches and necklace during operation. Insulated tools
should be used.
ØIf abnormality is found when the equipment is energized, turn off the
DC switch of the power module immediately. After the fault is rectified,
turn on the switches again.
ØMake sure the inverter is off before checking the APX battery system.
ØAvoid contact with any parts with electric potential difference.
ØPersonnel who install and operate the Battery System must receive
thorough training and possess the local national required qualifications
before operation. Only qualified professionals and trained personnel are
allowed to install, operate and maintain the equipment.

Step 1: Power off the APX system.
Step 2: Loosen the screws on the fuse shell.
Step 3: Lift the fuse box opening, remove the fuse, insert a new fuse into the slot, and
close the fuse box.
Step 4: Tighten the screws on the fuse shell.
ØAfter the system is powered off, the remaining electricity and heat still
exist in the chassis, which may cause electric shocks or burns. Therefore,
