Build Your Own Tesla SDU Openinverter Kit
🇺🇸 FREE Shipping within the USA 🇺🇸
Logic Board
The Openinverter SDU logic board allows you to control any non-Raven 2012-2020 Tesla Model S/X Front or Rear Small Drive Unit (SDU) for use in EV conversions and custom electric vehicles. It will NOT work in a Tesla vehicle!
All components and connectors are included and fully soldered. The board has been flashed with the latest firmware and parameters and has been tested. Once installed, you can access the inverter parameters via an easy-to-use web interface to tune the motor for your application. SDU boards supplied by Westside EV have been slightly modified so that the plastic MX150 connector fits better on the board and avoids breaking off the little leg protruding from the bottom of the connector.
Openinverter boards include an onboard ~5kW charging feature, so you don't need to buy and integrate a separate onboard charger if fast charging is not required. However, this advanced feature should only be implemented by trained professionals as it requires working with high voltage.
NOTE: Installation is not for beginners! It requires soldering delicate current sensors and moving fragile plastic parts from the old board to the new board.
Watch this comprehensive installation video for guidance.
Current Sensors (Included)
Two new Melexis 7.3mV/mT current sensors are included, so you don’t have to worry about removing and reusing the existing sensors without damaging them.
Wiring Harness
Simplify your Openinverter setup with our optional, fully labeled MX150 wiring harness pigtail. Crafted from high-quality 18 AWG silicone wire, this harness is color-coded and clearly labeled to match the Openinverter logic board pinout. A full-color pinout card is included for easy reference.
Our standard 1-meter harnesses are in stock and ready to ship, while longer lengths are made to order and may require additional processing time.
Contactors
Used/refurbished Kilovac EV200AAANA high voltage contactors. These contactors feature an economizer and can handle 500 amps and up to 900vdc. Contactors show signs of use and/or refurbishment but have been tested and confirmed to be in good working condition. These units are very expensive new, so you are saving a LOT with these refurbished ones.
Voltage (Max) (VDC): 900
Coil Voltage Rating (VDC): 9 – 36
Coil Resistance (Ω): 3.14
Contact Switching Voltage (Max) : 900
Contact Current Rating (A): 500
