What’s the Difference Between Single Phase, Split Phase, and Three Phase Inverters?
Hello everyone, when we buy inverters, we will hear about single-phase inverters, split-phase inverters, and three-phase inverters. Today, we will share the differences among these three.
First of all, we need to know that the engineering of inverter refers to the process of converting DC into AC. The circuit that completes the inverter function is called an inverter circuit. The machine that realizes the inverter process is our inverter.
Secondly, let's talk about what is "phase"? "Phase" refers to the three-phase live wire (A/B/C). The transformer generally outputs three live wires and a neutral wire (N wire), and usually has a ground wire (PE).
However, we will tell you about their principles as follow:
Single phase inverter consists of a live wire and a neutral wire. The standard voltage between A-N, B-N, C-N is 220V.
Split-phase inverter consists of any two-phase live wire (A-B, B-C, A-C) in the three-phase, the voltage is 380V. For example, the voltage in the United States is split-phase voltage 110v and 220v.
The three-phase inverter is the three live wires, represented by ABC. For example, the three-phase inverter voltage is only 380V. If there is a neutral wire in addition to the three live wires, the voltage will be 220V and 380V. Three-phase voltage is mainly used in industrial areas.
