......saves me again. We are in the middle a severe thunder storm and my PI EMS just shut the power off as it reached 127V and turned it back on again. This was one of the best purchases I have made. ...

I was at the same state park last year as I am now and was concerned about low shore power voltage during the hot period of the day. I have a PI unit and the voltage never got low enough that the PI shut it off to my 5'er. I was still concerned about my a/c's and low voltage so I looked up the operating specifications for my two Coleman units. I was surprised to see they are designed to operate at 115V, NOT 120V as I had thought. So the low of 108-109v that I have seen is just 5% or so lower than the design voltage of 115V. Why does my PI shut off at 104? Because 115V less 10% is 103.5V which is the absolute low to operate the a/c's. That is why the PI, and others, are set to shut down the power at 104V.
