BMS RJ45 Communication Cable for Fogstar Batteries | Voltacon

This RJ45 ethernet type BMS cable links Fogstar lithium batteries to Voltacon off grid inverters, allowing the inverter to read BMS data and manage charging correctly once the right lithium protocol is set.

Key features

• Connector type, RJ45 ethernet style plug
• Compatibility, Fogstar lithium batteries paired with Voltacon off grid inverters
• Pin layout, matches the RS485 communication chipset used for BMS data exchange on Voltacon off grid inverters only

Inverter protocol setting

Set the battery protocol to PYL (Pylontech) in the inverter menu. This is 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 for its location).
• Connect the other end to the battery RS485 communication port.

Applications

Intended for off grid solar setups using Fogstar lithium battery storage alongside Voltacon inverters, where correct BMS communication is needed for safe, stable charging.
