Technical FAQs 4

What is a DC inverter & converter?

The standard covers requirements for inverter and converter equipment that are intended to convert DC power from a renewable energy source into AC power that can be used by the electrical grid or other electrical loads.

Why do LCD screens need an inverter?

Inverters are essential for an LCD screen as they convert DC (Direct Current) from the power supply to AC (Alternating Current), enabling the backlight to function. Without an inverter, the screen would remain dim and unusable because the backlight is what makes the display visible.

What are the IEC standards for inverters?

IEC standards 2 provide several important guidelines for inverters, focusing on safety and performance: IEC 62109: Comprises both IEC 62109-1 and IEC 62109-2, outlining general and specific safety requirements for inverters used in photovoltaic systems.

How does an LCD inverter work?

In simple terms, an LCD inverter takes the direct current (DC) power from the device’s battery or power supply and converts it into the alternating current (AC) power needed to light up the screen’s backlight. This backlight is what allows you to see the images on the LCD panel. There are two main types of LCD backlights that use inverters:
