testing inverter output
Didn't find this one in searches. 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 b...

Problem:
There are a lot of modified Square wave inverters that call themselves modified sine.
There are a lot of inverters that are advertised as pure sine wave that are really Modified Sine wave inverters.
There are a very few Pure Sine wave inverters. If in doubt, call the manufacturer and ask for the Total Harmonic Distortion is...
They will lie and say that the third order is less than 5%.
Your only hope is to try out the inverter with the device you are planning to power with it. This is the only test you can do without a lot of really expensive gear.
Before the depression, I saw this a lot with "pure sine" inverters that were trying to run: Microwaves, Flat TVs and computers. Audio equipment not so much.
