What is the difference between single-phase inverter and three-phase inverter?

1. Single phase inverter

Inverter is to convert DC inverter into AC output, single-phase inverter is to convert the AC voltage into a single-phase, that is, AC220V.

There are three ports in the interface of the single-phase inverter, marking "N", "L" and "PE" respectively.

L means that the live line (logo\'L\'Live Wire) is red or brown.

N means zero line (logo\'N\'Null wire) with blue or white line.

PE represents the ground line (the letter is\'E\'Earth) with a yellow green line.

2.Three phase inverter

Three-phase inverter is converted to three-phase AC voltage, namely AC380V, three-phase electricity is composed of three AC potential with the same frequency, equal amplitude, phase difference 120 degrees in turn.

The interface of three-phase inverter has five holes, followed by A, B, C, N and PE. A is yellow, B is green, C is red, N is zero line, blue or white; PE is ground line, yellow and green. A, B and C may also be L1, L2, L3, U, V, W.

Simple induction is: 5 port interface, 400V voltage level.
