EL wire + inverter questions
The image in the link reads DC12V so you should only supply the inverter with 12V DC. EL wire requirements vary. Your question is a little difficult to parse, but in my experience EL wires need a relatively high AC voltage (~100v) at a high frequency (~60-2Khz) in order to operate. You should check the specs on the wire if you want to use something other than the suggested inverter.
