2.1-Single inverter
2.2-Multiple inverters
The maximum current for the busbar cross-section is 300A. When multiple inverters are connected, the total current may exceed 300A. In this case, you can change the inverter connection points to ensure that the current in each cross-section of the busbar does not exceed 300A.
Requirements:
The connection points of the battery positive and negative terminals to the busbar should be evenly distributed.
The connection points of the inverters to the busbar should be evenly distributed.
2.3-Multiple inverters & busbars
The wires connecting the busbars should be configured according to the maximum current of the inverter.
Communication Connection
1.Communication Between Batteries
Use standard network cables to connect the communication ports of the batteries. (RS485 cable inclued in the battery package)
Connect the C-down port of the upper-level battery to the C-up port of the lower-level battery. The highest-level battery is the master battery, The othes are slave batteries.
For multiple stacks/cabinets, connect the C-down port of the lowest-level battery in the first stack/cabinet to the C-up port of the highest-level battery in the second stack/cabinet.
All batteries in the second cabinet will be slave batteries.
DIP switch of all slave batteries is default, Pls check image as below.
DIP switch of master battery depends on the inverter brand.
2. Communication between the master battery and the inverter
Connect the C-up port of the master battery to the inverter's BMS interface with communication cable. Different brand inverters have different BMS interfaces, the communication cables
3. Communication connection between the battery system and the PC (used for checking battery information)
Insert the RJ45 plug of the included RS485 to USB communication cable into the C-up port of the master battery (remove the communication plug connected to the inverter first, if necessary). Insert the USB plug of the communication cable into the computer's USB port. After installing the corresponding communication cable driver, you can run the software to monitor the battery (please refer to the corresponding manual for detailed software operation)
1).Buy the RS485 cable from RUiXU website
2).Make the cable yourself
3).The CAN to USB adapter can be made according to the corresponding wiring sequence.
4. Communication with solar assistant
RUiXU battery pack can be connected to the solar assistant using either RS485 or CAN communication
1) CAN Communication
Pls order CAN bus USB cable from solar assistant directly,corresponding wiring sequence as below.
· Connect the C-up port of the master battery to the inverter, and connect the last battery to the solar assistant.
· Connect the C-up port of the master battery to a splitter, and then connect both the inverter and the solar assistant to the splitter.
Settings:
Battery Settings: Solar Assistant only supports Dyness/Pylontech CAN protocol, the master battery's CAN protocol need to be set to Dyness/Pylontech CAN protocol (Set bit6 and bit7 DIP switches of the master battery to ON and OFF)
1.If the battery is communicating with the inverter using CAN, the communication protocol between the inverter and the battery must also use the Dyness/Pylontech CAN protocol. (such as Victron CAN protocol, will not work.)
2. If the battery is communicating with the inverter using RS485 protocol, set master DIP switches bit3 and bit4 according to the inverter's communication protocol requirements. keep the master battery's DIP switches bit6 and bit7 set to ON and OFF.
Solar Assistant Battery: Select USB CAN BUS.
2) RS 485 Communication
Communication cable
Using an RS485 to USB cable, which can be purchased directly from RUIXU or Solar assistant, or you can purchase an RS485 to USB adapter to make it by yourself. The wiring sequence is as below:
Communication port selection:
It can only be connected to the C-up port of the master battery. If communicating with the inverter, the communication between the inverter and the battery must only be via CAN. The inverter can be connected to the C-down port of the last slave battery, or it can be connected to a splitter at the C-up port of the master battery, with both the inverter and the solar assistant connected to the splitter.
Settings:
Battery Settings: Since the Solar Assistant supports Voltronic LIB RS485 protocol, set the RS485 protocol of the master battery to Voltronic LIB RS485 protocol. Set DIP switches 3 and 4 of the master battery to OFF. DIP switches 6 and 7 of the master battery should be set according to the CAN protocol required for communication with the inverter.
Solar Assistant Battery: Select USB Voltronic LIB RS485
