This page is dedicated to use of Toyota inverters unmodified via the serial protocol (REQ, CLK, HTM, MTH). This page also contains wiring and connector information for the various models of Toyota Inverters.

Toyota Protocol

  • REQ Request line from hybrid controller to Inverter
  • CLK Clock signal from hybrid controller to Inverter (Constant 500KHz)
  • HTM Hybrid controller to Inverter data frame
  • MTH Inverter to Hybrid controller data frame

The number of bytes sent/received during a transfer will depend on the model of inverter, the table bel at 500kbpsow outlines the number of bytes for the different inverter models:-
