Summary: Understanding line voltage and phase voltage in inverters is critical for optimizing energy systems. This article explains their differences, real-world applications, and how proper voltage management enhances efficiency across industries like renewable energy and manufacturing.

What Are Inverter Line Voltage and Phase Voltage?

In three-phase power systems, line voltage refers to the voltage between any two phases, while phase voltage measures the voltage between a single phase and the neutral point. For example:

• In a 400V three-phase system, line voltage = 400V
• Phase voltage = 400V ÷ √3 ≈ 230V
