FAQ

What are the differences between single-phase inverters and three-phase inverters?

Application scenarios: Single-phase inverters are mainly suitable for small-power scenarios such as small photovoltaic power stations and household rooftop photovoltaic power stations. Their output power range is usually between 1-10kW. Three-phase inverters are more suitable for high-power scenarios such as large photovoltaic power stations and industrial applications. Their output power is generally above 10kW, and can even reach hundreds of kilowatts or higher.
Circuit structure: The circuit structure of a single-phase inverter is relatively simple and mainly consists of three parts: DC terminal, converter, and AC terminal. The circuit structure of the three-phase inverter is more complex, including six main parts: DC terminal, input inductor, three converters, three filters, and AC terminal.
Price: Due to the large market demand and relatively low production costs of single-phase inverters, their prices are usually lower than those of three-phase inverters. Three-phase inverters are mainly used in large-scale industrial and commercial applications with higher performance requirements, so the price is relatively high.
Advantages: The advantages of the reliable single-phase inverter are cheap price, easy installation, and wide application range. However, its output power is relatively low and it is mainly suitable for low-power household appliances. The advantage of the three-phase inverter is that it has high output power and is suitable for large commercial and industrial power consumption.

Solid 0.75kW VFD for light-duty work.

I’ve been using this 0.75kW VFD to control a small 3-phase motor, and it runs smoothly. The sensorless vector control gives decent torque even at low speeds, and it handles voltage variations just fine. Just make sure it’s installed in a clean spot—IP20 means it’s not dustproof.

Affordable 0.75kW frequency inverter

This 0.75kW frequency inverter is compact, easy to set up, and handles my 3-phase equipment perfectly. The sensorless vector control keeps everything running smoothly, even in tough conditions.
