If using a modified sine wave inverter, is there a simple way to test how clean the power output is>
I mean a way to tell if it is dangerous for certain things to be used on it.
Thanks in advance.

Sadly yes. and you already answsered it MSW inverters are a problem with some devices.

Now the biggest issues are also the smallest issues,, TVs may have a wavy picture or bars that move accross... Audio systems have hum or buzz.. and AM Radio.. Forget it... But there is no damage.

I have read of a night light that flamed on (LED type) and Electric Blanket controllers which failed. Generally things with electronic timers are affected.. But other than try it and see... It is kind of hard to tell because sometimes.. It works fine.
