S48-100LFP STACK-LV Communication Interface

COMMUNICATION INTERFACE

The BMS of the battery pack has one external CAN bus communication port and one

external RS-485 communication port for closed loop communication. All inverters, when

set with proper voltage and current setpoints for charge and discharge, can be used with

our batteries. A list of inverters which can take advantage of closed loop communication

can be found in Appendix A.

Note: Closed loop communication is essential for long-term performance and is a

requirement of product registration and the extended warranty offered on the

S48-100LFP STACK-LV model.

CAN COMMUNICATION
The CAN bus port pinout is shown below. See Appendix A or S48-100LFP STACK-LV Inverter Compatibility for compatible inverters.

RS-485 COMMUNICATION

The RS-485 port pinout is below. See Appendix A for compatible inverters.

When connecting between batteries over RS-485, a standard network cable is used.

LINK UP AND LINK DOWN COMMUNICATION

Batteries should be connected to each other via a separate RS-485 interface, with ports

dubbed “LINK UP” and “LINK DOWN”.
