Re: Solar Panel Help
You are correct, in that you need an inverter circuit. I doubt the pump will operate on DC. I'm not aware of any off the shelf devices for 12VDC to 12VAC but I'm sure they must exist somewhere. Some are better than others, in the quality of the waveform produced. Not knowing how your pump works, you may get away with a square wave, you may not.
Might take a look at building something like this:

or like this:

You might also consider using a 555 timer, and a band-pass filter to create a pseud0-sine wave.
Perhaps one of the EE's on this forum can chime in.
