I looked at the "sine wave" output of these devices on an oscilloscope, and it is actually more of a square-wave than a sine wave (which should be rounded). This is the reason for their disclaimer. In practical use, I have not had any problem using my inverter, which uses the square wave that they call a "modified sine wave." -Ron Salmon The Bus Depot http://www.busdepot.com (610) 754-VWVW |
