WTB: MPP LV1012 or other 12v AIO for a basic solar class - Seattle area

[Rednecktek]

Anyone got an old 12v AIO system they'll let go cheap? I'm looking at teaching a basics intro-to-solar class and I've got everything I need other than a basic 12v inverter and a "This Is How You Cheat" AIO.

I'm trying to make as much of it as practical as I can so we'll be wiring up panels and SCC's and such. Since I'm donating my time and equipment I'd like to keep it cheap.

Thanks gang!
