Solar Pump Inverter AX300

SKU AX300 Category



The AX300 series features high-performance vector algorithms and a modular design. Low frequency, high torque, smooth speed, and powerful functions, can be freely combined according to the needs of different industries.

The AX300 series can drive three-phase asynchronous motors and three-phase synchronous motors for speed control. It can be used in industries such as textiles, machine tools, paper making, printing, packaging, wire drawing machines, food, woodworking, fans, water pumps, etc.


● Frequency setting methods: digital setting, analog setting, serial communication setting, multi-segment speed, PID setting, etc;

● PID control function;

● Multi-stage speed control function: 16-stage speed control;

● Swing frequency control function;

● Instantaneous power failure without shutdown function;

● M-key function: a multi-functional shortcut key freely defined by the user;

● Automatic voltage adjustment function: When the grid voltage changes, it can automatically maintain the output voltage constant;

● Provide up to 25 fault protection functions: overcurrent, overvoltage, under voltage, over temperature, phase loss, overload, and other protection functions.
