6 FAQs about Inverters & Power System Solutions

Does a power inverter need a pure sine wave?

If you’re planning to run sensitive electronics or inductive loads from your power inverter then it’s crucial to know if it’s pure sine wave. Things like medical devices, compressors, refrigerators, LED TVs all need pure sine wave otherwise you risk damage and overheating. Plus they won’t work efficiently.

Is a pure sine wave inverter better than a modified sine wave?

Pure sine wave inverters are generally considered to be more suitable for powering sensitive electronic devices and appliances. In comparison, modified sine wave inverters may be a more cost-effective option for basic power needs. When Do You Need a Pure Sine Wave Inverter?

How does a sine wave inverter work?

Electricity that comes from the power grid is in the form of a sine wave—a smooth, repeating wave that maintains a consistent frequency (usually 50 or 60 Hz). A pure sine wave inverter produces a waveform that closely mimics utility-grade electricity, making it ideal for running sensitive or high-performance equipment.

What is a modified sine wave inverter?

Modified sine wave inverters use simpler and cheaper electronics to produce a wave that is not quite a smooth sine wave. Pure sine wave inverters use more expensive electronics to generate a wave that is very close to a pure sine wave. The figure below compares outputs from a modified sine waver inverter and a pure sine wave inverter.

How do I know if my inverter is pure sine wave?

In my experience, there are 3 easy ways to test if your inverter is pure sine wave. You can use extra equipment, deal with the manufacturer, or even just listen to the sound it makes. By far the best way to determine the output of your inverter is with an oscilloscope.

What are the different types of sine wave inverters?

Sine wave inverters are available in two basic types: pure sine wave inverters and modified sine wave inverters. The difference is basically in the electronics. Modified sine wave inverters use simpler and cheaper electronics to produce a wave that is not quite a smooth sine wave.
