modified sine wave inverter to power MyRio?

Helllo

I am going into uncharted territory for my senior design project. I need to build an MPPT circuit to efficiently charge a 55AH or 75AH battery.

The design because of my lack of programming expertise is going to for the moment be based off of the MyRio. Unlike most controllers I've seen, the Rio needs a DC power supply to function so I need to be able to plug its AC/DC adapter to an inverter which would be connected to the battery

I went to my car today with this inverter: http://www.rosewill.com/products/1738/ProductDetail_Specifications.htm http://www.rosewill.com/products/1738/ProductDetail_Specifications.htm

I didnt seem to have any problems with my ThinkPad Yoga charging on it and the myRio plugged into it. that being said, I only intend to run stuff off this inverter for at most 3-4 monthswhich is the duration of the project.

Is there a big risk of frying my components? Also would using such a source introduce too much noise. I would buy a proper sinewave but those things are very expensive.

(note most of my work will be done in a lab or at home with utility AC). I will test the circuit prbly for 120 hours at most on the battery/solar setup which includes demo purposes.

Edo101,

 

I doubt you will damage the myRIO by using a modified sine wave inverter. You may see some additional noise on analog inputs and outputs, but unless you need a very high level of accuracy, I doubt that would be too much of an issue either.
