Welcome to the openinverter.org Wiki Site.

The open inverter project consists of some reference designs for the control hardware using an STM32F103, the inverter firmware, and an easy to use web interface. Other hardware variants include drop in boards for Tesla small and large drive units.

If you have received a kit you are probably looking for build instructions.

If you want to tune your inverter check the parameter description.

You might also want to set up CAN communication or use the inverter as a battery charger also.

If you need help with your EV conversion check out my consulting offers.
