Navitas AC Controller for Golf Carts & EVs – Plug & Play Upgrade

In the world of electric golf carts, upgrades are no longer limited to tires, seats, or body customization. One of the most impactful enhancements you can make is at the heart of the cart’s powertrain — the controller. And when it comes to top-tier control systems, few names command as much respect as the Navitas Controller.

At Prime Golf Parts, we specialize in advanced golf cart components, and offering Navitas controllers is central to our mission: to help you maximize performance, efficiency, and customization potential.

What Is a Navitas Controller?

A Navitas Controller is a high-performance electric controller designed for low-speed electric vehicles (LSEVs) like golf carts, utility vehicles, and even light industrial EVs. It handles the management and regulation of electrical current flowing from your batteries to the motor, deciding how much power to deliver based on throttle input, conditions, and programmed settings.

Navitas offers both DC (direct current) and AC (alternating current) controllers, and even full DC‑to‑AC conversion kits, which let you convert a legacy DC golf cart to an AC drive system.

Key Models & Lines

  • TSX3.0 — A separately excited DC controller that supports features like regenerative braking, smooth reversing, and smartphone tuning.

  • TAC2 / TAC series — AC controllers, commonly used in conversion kits, for upgraded performance and efficiency in AC motor setups.

  • DC to AC Conversion Kits — These include the controller, motor (often 4 kW or 5 kW), and all necessary wiring and hardware.


Why Upgrade to a Navitas Controller?

Upgrading or installing a Navitas system offers several compelling benefits:

  1. Increased Power & Torque



  • You can choose from controllers with 440 A or 600 A ratings, giving you stronger acceleration and greater climbing capability.

  • For example, the Navitas 600‑Amp Controller Kit for Yamaha G19/G22/Drive models claims up to 75% more torque over stock controllers.



  1. Enhanced Efficiency & Range



  • The intelligent control, regenerative braking, and precise current management help extract more usable range per charge.

  • In AC setups, performance gains are often more pronounced, especially when paired with modern lithium battery systems.



  1. Customizability & Control



  • Via Bluetooth or On-The-Fly (OTF) programmer, you can fine-tune acceleration curves, max speed, braking aggressiveness, and other parameters.

  • Lockout features prevent unauthorized tweaks, making the setup safer for fleet or club use.



  1. Plug‑and‑Play Compatibility



  • Navitas designs its controllers to work with the harnesses and wiring layouts of common golf cart brands: EZGO, Club Car, Yamaha, ICON, Star EV, Columbia, etc.

  • Many offerings at Prime Golf Parts are preconfigured to suit specific cart models (for example, “Navitas Controller for EZGO TXT 48V (440/600 Amp)”). P



  1. Durability and Safety



  • The controllers are sealed for protection, include thermal and voltage safeguards, and support current limiting to protect components.

  • Regenerative braking and motor over‑speed protection are built in to mitigate damage or loss of control.


Real-World Evidence & User Experience

While manufacturer specs paint an ideal picture, user feedback provides valuable insight into actual behavior.

  • One Reddit user reports upgrading a 2012 RXV with a 440 A Navitas and lithium setup, going from 15 mph to over 42 mph (though some caution is used).

  • Others mention hill climbing issues when settings or battery configurations are mismatched.

  • Some users report latency or throttle response quirks, especially after AC conversion, which may be tied to tuning settings or firmware.

  • In a post about a blinking LED error (7 blinks), the user realized it came from a Navitas controller, highlighting the importance of understanding the controller’s diagnostics.


These experiences show that while the Navitas Controller offers great potential, correct setup, tuning, and component matching (motor, battery, wiring) are crucial to fully benefit from it.

Choosing the Right Navitas Setup for Your Golf Cart

DC vs AC

  • DC controllers (e.g. TSX series) are ideal for carts built with DC motors and wiring systems. They can deliver significant performance upgrades without a full drivetrain overhaul.

  • AC controllers (e.g. TAC2) are part of full DC to AC Conversion Kits. Switching to AC often unlocks better efficiency, smoother operation, and higher torque — but requires more involved installation (motor swap, wiring changes).


Amp Rating

  • 440 A: Safer, smoother upgrade for many carts, especially if you want to preserve longevity of existing motors and batteries.

  • 600 A: More aggressive performance. Best paired with high-quality battery systems, upgraded wiring, and good cooling.


Match to Your Cart Model

Ensure that the controller you purchase is compatible with your cart’s brand, model, connector types, and voltage. On Prime Golf Parts, you'll find options like Navitas Controller for Yamaha G14/G16, 36/48V or Navitas AC Controller for EZGO RXV.

Supporting Parts & Accessories

  • Wiring harnesses, sensor cables, and conversion kits are offered alongside controllers.

  • You’ll also want the On-The-Fly (OTF) programmer to make real-time adjustments during testing.

  • If doing AC conversion, a new AC motor (e.g. 4 kW, 5 kW, or higher) may be required.


How to Install & Tune Your Navitas Controller

While the installation steps will vary depending on cart make and whether you’re doing DC or AC, here is a general outline:

  1. Disconnect battery and isolate power — Safety first.

  2. Remove the existing controller and wiring harness carefully, labeling wires if needed.

  3. Mount the new Navitas controller in a suitable location with vibration isolation.

  4. Connect the harnesses, including motor leads, throttle, forward/reverse wiring, etc., following manufacturer instructions.

  5. Reconnect the battery with heavy gauge wiring.

  6. Power it up and use the Navitas app or OTF programmer to set foundational parameters: battery type, voltage, max amps, speed limits, regen strength.

  7. Test in a controlled environment, monitor current, temperature, behavior, and adjust settings as necessary.

  8. Lock configurations or limit changes if needed.


If issues arise (e.g. blinking error codes, cutouts uphill, throttle lag), Navitas technical support or community forums can often help you walk through diagnostics. As one user noted, they had a blinking LED on a 2017 Cart after a tow/ride switch flip — ultimately tracked to the controller.
