Connecting the JK BMS

Protocol selection

On the SolarAssistant configuration page, select the protocol below.

Connections and components

The typical setup requires the two components below. We do not sell any of them.

  • JK BMS RS485 module
  • USB RS485 adapter (ensure it's not TTL). We recommend FTDI chip adapters.

Note you can also use a USB TTL adapter instead of the two adapters above, but it requires manual wiring into the JK BMS where the JK BMS RS485 module connects.
