FAQ

How to wire a single phase to a three phase frequency inverter?

When wiring single-phase to 3 phase inverters, special attention needs to be paid to ensure that the circuit operates normally, the wiring is firm and reliable and prevents poor contact or short circuit. There are two main ways of wiring, namely star connection and delta connection.
The y-type connection method is suitable for motors with a rated voltage of 380V and below. In this wiring method, the U, V, and W lines of the three-phase motor need to be connected to the corresponding terminals in sequence, and then the midpoints of the three lines are connected to form a star connection.
Delta connection method is suitable for motors with a rated voltage of 380V and above. In this wiring method, the U, V, and W lines of the three-phase motor need to be connected to the corresponding terminals in sequence to form a diamond connection, and finally, the other ends of the three lines are connected to form a triangle connection way.

Great 0.4 kW frequency inverter for light-duty gear.

I’m using this 0.4 kW inverter to drive a small 3-phase motor on a benchtop lathe, and it works exactly as expected. Converts single-phase to three-phase smoothly, and the speed control is responsive across the full range. Just make sure your load stays within its limits.

Good inverter but limited to basic applications

The 0.4 kW single-phase to three-phase frequency inverter works well for basic motor speed control, and I've found it particularly useful for my water pumps and fans. It's easy to set up. However, the IP20 rating limits where you can use it safely—not ideal for harsher environments. Overall, it’s reliable but best suited for controlled indoor settings.

The inverter's compatibility is an issue

While it claims to convert single-phase power to three-phase, it may not work seamlessly with all types of machinery and equipment. This lack of compatibility can lead to complications and potentially render the inverter useless for specific applications.

Super easy to use

Super easy to use. This is a very nice frequency inverter for the price. Everything is adjustable, but it'll run right out of the box. I have been using it for about 1 month and have really worked. I highly recommend this one.

Buying 0.4kW inverter is a good deal

In terms of the price and quality of 0.4kW single phase to three phase inverters, this is a good deal. Factory direct prices allow me to buy high quality products at very cheap prices. It controls the motor at a very strong speed, and new employees of the company like to use it.
