BMS RS485 Box for Pylontech Batteries | Voltronic InfiniSolar

This external BMS RS485 interface box lets a Voltronic InfiniSolar hybrid inverter communicate directly with a Pylontech lithium battery bank. It connects via the inverter's RS232 port, so there is no need to open the inverter case or fit an internal card. Data cables are supplied, and the box works with the InfiniSolar 3kW, 5kW Plus and three phase 10kW models.

Key features of this off grid hybrid inverter accessory

• Connection type, external box wired to the inverter's RS232 port
• Compatibility, InfiniSolar 3kW, 5kW Plus and three phase 10kW
• Included cables, data cables supplied for connection
• Charge control, enables automatic charge management using Pylontech battery BMS data
• Discharge control, lets the inverter start and stop discharging based on battery status

Applications

Built for systems pairing a Pylontech lithium battery bank with a Voltronic InfiniSolar hybrid inverter. It suits off grid and hybrid installations where the inverter needs live battery status to manage charge and discharge cycles automatically, without manual intervention from the installer once configured.

Installation notes

Connect the box to the inverter's RS232 port using the supplied cable, then connect it to the Pylontech battery communication port. The inverter itself needs to be configured to talk to the BMS box; the correct communication settings are in the InfiniSolar installation manual.
