    What type of Inverter are you using?

    Pure Sine Wave?

    or

    Modified Sine Wave?


    Do you see any advantages to either? I only ask because modified sine is much cheaper than pure, but pure is more efficient and less likely to have problems with the equipment it's running. Thanks!

    Pure is better, give a smoother signal and will be less likely to cause noise. You may want to check into a DC-DC power supply though, as they are not much more money compared to a really high end inverter...

    Using modified sine-wave here. Pure sine-wave inverters are basically like modified sine-wave inverters except the steps are chopped up at 20 KHz.

    Um, my understanding was that a pure sine wave was a pure sine wave, and that a modified sine wave was a square wave with a step in it... am I wrong here?

    Im using a modified sine wave, yes pure is more expensive, modified is more cheaper. Try to find a cheap modified one that survives cranks and has enough watts for what you need. Mine does, but you may have to try a few - also some make more noise then others, so you might want to watch out for that too.

    How bad is the noise? I've also heard you don't want to run high end electronics off a modified sine wave...

    I run a modified sine wave inverter. The only noise I get is in the power supply itself. It seems that the transformer doesn't enjoy the hard steps of the modified wave, creates a little buzz.
