Modified Sine Inverter

What is it?

Modified sine power inverter is an inverter (electronic device) which transforms the current from a DC to AC and puts out a modified current wave similar but not identical with the one in a house grid. (see the picture below). There are many types of inverters of this kind, customised based on different countries house grid voltages for example if you live in Australia you would buy a 240v output, most of Europe and China 220v in UK 230v, in US 110v.

How does it work?

The current produced by this standard power inverter will be similar but not perfectly identical with the one you use at home.

It needs to be connected to a battery or a battery bank as an input, from there it transformes the current from DC to AC and creates a wave similar but not identical with the house grid current wave. It has an output, usually looks similar with a power point where you can connect appliances.


You can notice the difference in some fine electronics like TV, radio, some lighting, etc. If you intend to use it for this fine electronics I would not suggest this product as it can do some damage in a long term, but I would suggest a pure sine inverter.
