A better ride from the cart you already own
Navitas Vehicle Systems makes electric vehicle control systems and golf car conversion kits for low-speed vehicles. If you want more speed and torque, smoother control, or to convert a DC cart to AC, we can help you choose the right kit and install it.
Stop by any of our stores, call (704) 302-1200, or send us a note with your cart details. We’ll confirm what fits and send you a quote.
Navitas AC motors and DC-to-AC conversion
Navitas AC induction motors come in 3 kW, 4 kW, and 5 kW. They use a steel and aluminum construction, an external speed sensor, and 10-tooth or 19-tooth spline options, with or without a motor brake.
These motors are used with Navitas TAC2 DC-to-AC conversion kits, which replace a stock DC setup with an AC motor and a TAC2 controller. Navitas lists applications that include golf cars, utility vehicles, personnel carriers, UTVs, LSVs, and hunting buggies.
Navitas designs the kits as plug-and-play for many popular golf cars, with no need to cut or modify the cart. Navitas also says its compact AC systems are built for more miles per charge and stronger performance. The right motor size depends on your cart and the kit we recommend.
Navitas controllers
TAC2 AC controller
The TAC2 is Navitas’s fully programmable controller for AC induction motors, made for on-road and off-road vehicles. It is the controller used in Navitas DC-to-AC conversion kits.
Features Navitas lists for the TAC2 include:
- 440A to 600A MOSFET design, compact size, and a fully sealed IP65 case
- Regenerative braking, rollback protection, and speed limiting
- Thermal and under-voltage protection
- Bluetooth and CAN (module specific), so you can adjust settings such as current limits, maximum speeds in forward and reverse, and battery over-discharge protection
- Plug-and-play installation for many popular golf cars, plus an optional Navitas On-The-Fly (OTF) programmer
TSX3.0 DC controller
The TSX3.0 is Navitas’s programmable controller for separately excited DC motors. It is built to optimize motor performance and allow smooth reversing.
Features Navitas lists for the TSX3.0 include:
- 36 to 48 volt operation, with 440A and 600A options, in a compact, fully sealed IP65 case
- Regenerative braking that can help manage speed and return energy, plus rollback protection and motor over-speed protection
- Contactor-less motor reversing, thermal and under-voltage protection, and speed limiting
- Bluetooth programming with the Navitas Dashboard App, including current limits, maximum speeds in forward and reverse, and battery over-discharge protection
- Plug-and-play installation for many popular golf cars, plus optional OTF programmer compatibility
The Navitas Dashboard App is available for iOS and Android. Navitas TAC, TAC2, and TSX3.0 controllers have Bluetooth and work with the app, so you can tune settings, view live data, and use lockout features. An optional OTF programmer lets you adjust speed, acceleration, and (on TSX controllers) regen while you drive, and you can lock those settings in.

Frequently asked questions
What is a Navitas upgrade?
Navitas Vehicle Systems makes golf cart motors, controllers, and DC-to-AC conversion kits. Queen City Carts sells and installs those upgrades, so you can add a Navitas motor or controller, or convert a DC cart to AC, on the cart you already own.
Will a Navitas kit fit my golf cart?
Navitas makes kits for many Club Car, E-Z-GO, and Yamaha models, plus some other low-speed vehicles. Fitment depends on the year, make, model, and the controller already in the cart. Some later Club Car Precedent models and Club Car Regen 2 carts are not compatible with certain kits. Share your cart details, or bring it in, and we’ll confirm the right fit.
What is the difference between the TAC2 and the TSX3.0?
The TAC2 is Navitas’s programmable controller for AC induction motors and is used in DC-to-AC conversion kits. The TSX3.0 is Navitas’s programmable controller for separately excited DC motors. Both offer regenerative braking, Bluetooth tuning, and optional On-The-Fly programmer support.
Can I adjust the settings myself?
Yes. Navitas TAC, TAC2, and TSX3.0 controllers have Bluetooth and work with the Navitas Dashboard App on iOS and Android. You can tune settings and view live data in the app. An optional On-The-Fly programmer can also adjust speed, acceleration, and (on TSX controllers) regen while you drive.
