Collection: AC Controller Upgrades

Upgrade the performance of a golf cart that already has a factory or existing AC drive system with an upgraded AC controller from Winnie's Golf Carts.

This collection is for golf carts that are already equipped with an AC motor system and do not need a full DC-to-AC conversion kit. Shop higher-amperage and performance AC controller upgrades designed to improve acceleration, torque, speed potential, and overall drivability on compatible carts.

Fitment depends on the golf cart year, make, model, voltage, motor system, wiring, CAN communication, and factory controller configuration. If you're unsure which AC controller upgrade fits your cart, contact us before ordering and we'll help verify compatibility.
