This has been a bit of a puzzle and is really for the Tech/Maths minded people.
Measuring A/C voltages with a conventional A/C voltmeter gives you the RMS voltage -Root Mean Square and this assumes a Sine Wave.
Invertors generally give out a stepped square wave - two or three steps. What is the correction factor on what you would read on a RMS voltmeter to get the "SAME" ?
We usually set Stepped Squarewave invertor to read 110 V A/C on an RMS voltmeter but if you switch from street to invertor incandecent lights get brighter. Street Voltage is 120 V A/C measured with the same voltmeter.
Cant find this googling it - any ideas/formulas, correction factors?
