and systems.
The LP2000 series has a built-in BMS battery management system, which
can manage and monitor battery voltage, current, temperature and other
information.
2.1 Product Features
1) Built-in soft start function, when the inverter needs to start from the
battery, it can reduce the current impact.
2) Double active protection at BMS level.
3) Automatically set the address when multiple groups are connected.
4) Support wake-up via 5~12V signal of RJ45 port.
5) Support the host controller to upgrade the battery module through CAN
or RS485 communication.
6) Enable 95% depth of discharge, which can be used for inverters
operating in full compliance with its protocol.
7) The module is non-toxic, non-polluting and environmentally friendly.
8) The cathode material is lithium iron phosphate, which has good safety
performance and long cycle life.
9) The battery management system (BMS) has protection functions such as
over-discharge, over-charge, over-current, high and low temperature, etc.
10) The system can automatically manage the charging and discharging
status and balance the voltage of each cell.
11) Flexible configuration, multiple battery modules can be connected in
parallel to expand capacity and power.
12) Adopt self-cooling method to quickly reduce the overall noise of the
system.
13) The module has less self-discharge, and can be put on the shelf for up
to 6 months without charging. There is no memory effect, and the
shallow charge and discharge performance is excellent.
14) Small size, light weight, easy installation and maintenance.

It is recommended to wear the following safety gear when dealing with
the battery pack.
4.1 Package Items
Unpack and check the pakcing list
(1) For battery module package：
①Single battery pack stanard package:1pc orange and black waterproof
terminal and OT(100A)
4. Installation and Operation
13
②Could be customization per require：battery cable、communication cable、
parallel cable、grounding cable.

14
（2） For battery system connecting to inverters:
Two long power cables (current capacity 120A, constant 100A) and one
communication cable for each energy storage system:
4.2 Installation Location
Make sure that the installation location meets the following conditions:
（1）The area is completely water proof.
（2）The floor is flat and level.
（3）There are no flammable or explosive materials.
（4）The ambient temperature is within the range from 0°C to 50°C.
（5）The temperature and humidity is maintained at a constant level.
（6）There is minimal dust and dirt in the area.
（7）The distance from heat source is more than 2 meters
（8）The distance from air outlet of inverter is more than 0.5 meters.
（9）The installation area shall avoid of direct sunlight.
（10）There is no mandatory ventilation requirements for battery module,
but please avoid of installation in confined area.The aeration shall
avoid of high salinity, humidity or temperature.
If the ambient temperature is outside the operating range, the battery pack
stops operating to protect itself. The optimal temperature range for the
battery pack to operate is 0°C to 50°C. Frequent exposure toharsh
temperatures may deteriorate the performance and life of the battery pack.

Install a grounding cable to the grounding point of the modules.
4.4 Installation Instruction
Grounding cables shall be 10AWG or higher yellow-green cables. After connection,
the resistance from battery grounding point to Ground connection point of room
or installed place shall smaller than 0.1Ω.1)
(1)Connect the cables to inverter.
(2)Connect the cables between battery modules.

Note:
(1) After the battery module powered on, the soft-start function takes 3sec
to active. After soft-starts battery ready to output high power.
(2) During capacity expansion or replacement, when parallel different
SOC/voltage of module together, please maintain the system in idle for
≥15mins or till the SOC LED becomes similarly(≤1dot difference) before
normal operation.
4.6 Power off
(1) Turn external power source off.
(2) Press red SW switch of master battery. Then all batteries will off.
(3) Turn off the power switch .
4.7 Multi-group mode
Connect power cable first:
(1) each pair of cable hold max 100A constant current. Connect enough pairs of
cable based on calculation of system current.
(2)Suitable protection breaker between battery system and inverter is required.
(3) Make sure all dip switch of master batteries are R 0XX, then turn ON batteries.
R: is the baud rate of RS485 needed, all master batteries shall be the same.
(4) After all batteries running and buzzer of master battery in group1 rings 3
times.Means all groups are online.
The interruption of each RS485 command shall at least≥1s.

18
Problem determination based on:
(1) Whether the battery can be turned on or not.
(2) If battery is turned on, check the red light is off, flashing or lighting.
(3) If the red light is off, check whether the battery can be
charged/discharged or not.
Possible conditions:
(1) Battery cannot turn on, switch ON and press the metal SW the lights
are all no lighting or flashing.
(1.1) Capacity too low, or module over discharged.
solution: use a charge or inverter to charge battery. If battery can
start, then keep charge the module and use monitor tools to check
the battery log.
If battery terminal voltage is ≤2.8V/cell, please use ≤0.05C to slowly
charge the module to avoid affect to SOH.
If battery terminal voltage is ＞2.8V/cell, it can use ≤0.5C to charge.
If battery cannot start, turn off battery and repair.
(2)The battery can turn on, but red light is lighting, and cannot charge or
discharge. If the red light is lighting, that means system is abnormal,
please check values as following.
(2.1)Temperature: Above 60 ℃ or under -10 ℃, the battery could not work.
Solution: to move battery to the normal operating temperature range
between 0℃ and 50℃.
(2.2)Current: If current exceeds 100A, battery protection will turn on.
Solution: Check whether current is too large or not, if it is, change the
settings on power supply side.
(2.3)High Voltage: If charging voltage is over 3.65V per cell, battery
protection will turn on. Solution: Check whether voltage is too high
or not, if it is, to change the settings on power supply side. And
discharge the battery.
