## Questions

**Can I use X10 powerline communications with an inverter?**

## Answer

X10 devices will not run correctly off the average commerical inverter, which are usually modified sine wave or square wave. X10 powerline communications requires a pure sine wave inverter.

Here is a graph showing the difference:

X10 communications depend on a nice smooth sine wave that crosses the middle line (the "zero crossing point") on a smooth, predictable interval:

**If an inverter is not labeled as pure sine wave, assume that it is not safe for use with X10 devices.**

Pure sine wave inverters tend to cost about twice as much as modified sine wave inverters of equivalent wattage.

Many audio/video devices require pure sine wave inverters, so RV dealerships or stores often sell pure sine wave inverters.
