Installation process

Installation instructions

3.1 Installation notes
Before installation, please read this manual carefully and familiarize the installation steps.

1. Be sure to leave a certain space around for heat dissipation during installation.

2. Avoid sunlight direct and rainwater infiltration during outdoor installation to cause battery damage.

3. Do not place metal products near the place of the energy storage LiFePO4 battery installation to prevent short circuits.

4. Virtual connection points and corroded wires may generate high heat, and the molten insulation layer will burn surrounding materials and even cause a fire. Therefore, it must be ensured that the connector has been tightened and the wires should be secured with cable ties to avoid loosening of the connector due to shaking during
   mobile applications.

5. After the battery switch is turned off,there is still high voltage inside the energy storage case. Please do not open or touch the internal components, and external short circuit is strictly prohibited.

6. Please do not install it in a harsh environment where a large amount of damp, greasy, flammable and explosive dust gathers.

7. lt is forbidden to reverse the charging and discharging terminals of the battery, other wise it is very easy to damage the battery or cause unpredictable risks.

8. When the fan is working, please do not touch it to avoid injury.

9. When installing the battery on the wall, you must first ensure the bearing capacity of the wall and check whether the screws are installed firmly to avoid unnecessary danger.

10. lf an injury occurs during installation or use, please seek medical attention in time.

3.2 Installation and connection
Installation and connection must comply with national and local electrical code requirements. According to the current situation, firstly, choose the corresponding wire or a  wire with a larger wire diameter to avoid unnecessary troubles during use. Secondly, determine the installation location. Thirdly, when installing, please make sure to leave at  least 200 mm of space at the air outlets on both sides of the energy storage battery to ensure natural convection heat dissipation.
3.3 Recommended external wiring diameter and switch selection.

Model| Recommended extemal wiring diameter| Battery continuous current circuit breaker
---|---|---
POW-LIO48100-15S| 25mm² /4AWG| 100A
POW-LIO48200-15S| 25mm² /4AWG| 100A

Note: The wiring diameter is for reference only. If the distance between the load and the battery is relatively long,use a larger wire to reduce the voltage and improve the  system performance. The above wiring diameter and circuit breaker are only recommendations, please follow the actual choose the appropriate wire diameter and circuit breaker according to the situation.

3.4 Schematic diagram of the wall mounted installation

Warning: Danger of explosion! In order to avoid accidents, do not reverse connect the charging and discharging ports or short circuit, and do not install them in a closed environment. Rain proof and moisture-proof protection must be installed in the outdoor.
Attention!! The above steps can be omitted without wall mounting.
Attention!! When Only one battery is using inverter below 5kw or other loads below 5kw are recommended.
Attention!! Before making the final DC connection, please ensure that the battery switch / DC circuit breaker is disconnected, and ensure that the positive (+) must be connected to the negative positive(+), and the negative (-) must be connected to the negative(-).

As shown in the pictures above:

1. According to the actual situation,first install the wall mounting plate with M8 expansion screw on the wall to ensure that the installation is firm (picture 1).
   Note: the height of the expansion screw protruding from the wall shall be controlled within 25mm to avoid interference with the battery box during installation (Picture 2).

2. Fix the wall mounting bracket on the outer box of the battery with M6 screws, and ensure that the bolts are tightened with a torque of 2-3 nm (Picture 3).

3. After all the above are installed, hang they on the wall mounting bracket, and final lock the case and wall mounting bracket with M5 screws to prevent accidental tripping(Picture 4).

Schematic diagram of connecting

Note：

1. When the battery pack is used in parallel, it is necessary to distinguish different packs by hardware address, and the hardware address of each pack in the whole  battery pack is unique.
2.  lt must set up a park for the host park.The inverter communicate with host pack via PRS485/CAN. The hardwareaddress can be set successively through the dial switch on theboard.

Key Description

1. When the BMS is in sleep state, press the button (3~6S) and release it, the protection board will be activated, and the LED indicators will light up sequentially from  “RUN” for 0.5 seconds.
2. When the BMS is active, press the button (3~6S) and release it, the protection board will be put to sleep, and the LED indicators will light up sequentially for 0.5 seconds from the lowest battery indicator.
3. When the BMS is active, press the button (6~10S) and release it, the protection board will be reset, and all the LED lights will light up at the same time for 1.5 seconds.
4.  After the BMS is reset, the parameters and functions set by the host computer are still retained. If it is necessary to restore the initial parameters, it can be achieved  through the ” restore default value” of the host computer, but the relevant operation records and stored data remain unchanged (such as power, cycle times, etc.).

BMS communication settings

6.1 BMS communication and setting
When the load (such as inverter) needs to communicate with the battery, in order to establish normal communication with the load, BMS needs to set the following settings  for each brand. The RS485 communication protocols of inverters are different,but there are several RS485 communication protocols inside the inverter to match the battery.  When using,you can directly select the communication protocol code in the inverter for matching. If you have other problems, please consult the supplier.

Battery BMS interface pin foot definition as shown in the following figure

“ADS” is used for parallel use of battery packs.
PACK can be distinguished by hardware address.
The definition of ADS master-slavead dress refers to communication address selection specification. “PRS485/CAN” battery pack can communicate with the upper  computer or inverter and the reverse control integrated machine through the interface. “RS485” is used in parallel for battery pack,and the main communicates with pack from the interface.

The battery communication interface adopts 8P8C RJ45 socket.
