Again a result of using a modified SINE wave inverter. Many appliances react to this type of waveform (such as televisions generating lines across the screen, or radios having a hum through the speakers). There is not a great DEAL you can do to stop this except to upgrade pure sine wave inverter. TRY twisting the battery cables together and then wrap them in alfoil, as well as moving the inverter as FAR away from the INTERFERED appliance as possible (these are merely suggestions and may not work in every case).
