5. Electrical Connection User Manual
High voltage on the AC power supply port! Do not operate under voltage. Make sure the input side is completely voltage-free and the grounding cable is reliably grounded before cable connection.
SD card does not support hot plugging.
The RS485 communication cable must be shielded twisted pair cable and single-point grounded.
0.2mm² ≤ the maximum cross-sectional area of the shielded twisted pair ≤ 1.2mm², and the recommended stripped length of the cable is
8mm. Keep at least 0.5m away from the strong electricity. Avoid parallel cable
layout. Use the steel tube in area with strong interference. It is recommended to add an SPD if an outdoor device is connected to
the local controller. Otherwise, the local controller may be damaged by lightning.
The local controller supports a maximum of 6 RS485 buses. COM1 to COM 5 support connections to optional devices as well as PCS, battery BMS (BMS of Samsung battery only). COM6 is used to connect touch screen and other devices.
When more than 15 devices are connected to the RS485 bus, it is recommended to connect 12Ω resistors in parallel to A and B of the devices on two ends of the bus.
6.3 Communication Device Connection
Devices that can be connected to the local controller include PCS, BCP, and the like.
6.3.1 COM Port Connection
Devices are connected to serial ports of the local controller in the daisy chain manner by using the RS485 bus.
14
Page 21
User Manual 5. Electrical Connection
It is recommended that devices of different models need to be connected to the local controller separately. For example, connect the PCS and the battery BMS to different RS485 communication ports of the local controller.
Addresses of all devices connected to each input of the bus RS485 must be within set address range of the local controller and be different from each other. Otherwise, communication failure occurs.
The baud rate of all devices connected to each bus RS485 must be consistent with that of the local controller.
IP addresses of all devices must be on the same network segment as the local controller address, and be different from each other. Otherwise, communication failure occurs.
6.3.2 Internet Port Connection
The internet port of the local controller can be connected to the PCS. Connect both the local controller and to-be-connected devices to the switch through ETH1 and corresponding network ports, where Modbus-TCP communication protocol is supported.
6.4 Connection to System EMS
The local controller can be connected to the system EMS via the Ethernet port, and the communication protocol is standard Modbus-TCP.
The connection method is as follows: In the following, an example of the connection to the background monitoring
system through the Ethernet switch is used for description.
Step 1 Insert one end of the network cable (within the scope of delivery) to the
electricity port of the Ethernet switch and the other end to the port ETH2 of the local controller.
15
Page 22
5. Electrical Connection User Manual
IP addresses of ETH1 and ETH2 cannot be on the same network segment. Otherwise, communication error occurs.
Default IP address of ETH1 is IP192.168.0.100 Default IP address of ETH2 is IP192.168.1.100 ETH2 is used by default to set the WEB of the local controller, and the
IP address cannot activate the DHCP function.
The grounding cable must be well grounded. Otherwise: Lethal electrical shock occurs to the operator in a fault case! The device can be damaged by lightning!
Step 2 Set ETH2 IP address of the local controller to be on the same network
segment as that of the background monitoring system.
6.5 Protection Earthing Connection
Step 1 Prepare the grounding cable (recommended: outdoor copper-core cable
with cross-sectional area of 4mm2 to 6mm2 or 12AWG to 10AWG) and OT terminal.
Step 2 Crimp the grounding terminal shown in the following figure.
Step 3 Tighten the M4 screw to the grounding hole according to the sequence
shown in the figure below by using the wrench with fastening torque: 5± 1N·m.

DC cables are shown in the following table:
Step 2 Remove the phoenix terminal at the power supply port of the local
controller, and crimp the power supply terminal.
Step 3 Insert the power supply terminal to the corresponding DC/AC power

charge and discharge sections is at the lower limit 1 to the upper limit 1.
In the off-grid case, the battery SOC or the voltage section is
above the lower limit level 2.
Vbat upper limit 1 (2) level: battery charge voltage 1 (2) level upper limit
Vbat lower limit 1 (2) level: battery discharge voltage 1 (2) level upper limit
