Offgridtec's BMS-Link (MPN 013710) is an external BMS protocol inverter with an independent MCU. It is suitable for the 24 & 48V versions of the Offgridtec IC series, the BMS link cannot be used with the 12V version. The setting of "PRO" parameter is done through the remote meter or PC software after connecting the BMS link to IC and lithium battery.


  • Independent MCU
  • Dual RS485 com. port*
  • Multi BMS protocol conversion support
  • Free setting of log number
  • Reliable protocol conversion and communication
  • Optional remote counter or PC software to set log number
  • Easy installation and convenient operation
  • *The port connected to the lithium battery is an isolated RS485 communication port and the port connected to the all-in-one products is a non-isolated communication port.

Usable for different manufacturers

The protocols of different manufacturers can be converted to our standard protocol, which improves the flexibility of the actual application. Compared with the traditional built-in BMS protocol conversion module, this converter has greater application flexibility and expandability. It is more suitable for our all-in-one products and other products to communicate with the lithium battery BMS.
