BMS Communication Cable RJ45 Ethernet Type for Fogstar Batteries (SKU: 002945)

This RJ45 ethernet type BMS cable is designed for reliable communication between Fogstar lithium batteries and Voltacon off grid inverters. It enables the inverter to read battery BMS data correctly, supporting stable charging and safe battery operation when the correct lithium protocol is selected.

Inverter protocol setting

• Set the battery protocol to PYL (Pylontech) in the inverter menu.
• This matches the communication method used for Fogstar BMS integration with Voltacon off grid units.

How to connect

• Use the Lithium Ion communication port on the inverter (check the inverter manual).
• Connect to the battery RS485 communication port.

Pin configuration

This cable uses the correct RJ45 pin layout for Voltacon off grid inverters only. The pin configuration matches the RS485 communication chipset used for BMS data exchange.
