Progressive EMS-HW50C unit
We have Porgressive EMS-HW50C about 1.5 years old and hardwired at the dealership into our new camper. Yesterday about 1:00 a.m. we heard this loud tapping noise. We thought we had a large rat in ou...

One way to think of generators vs. home power is this.
Your home power is close to an "ideal voltage source" That is, the power coming into the house will deliver whatever current it needs to while keeping the voltage constant. Your power line is close to that, what causes voltage to drop is the resistance in the wire between your meter and the device sucking power.
Now, most generators can be thought of as a "current limited non ideal voltage source" It will deliver reasonably constant voltage till it gets to is maximum rated current, then the current remains constant and voltage drops to support that current draw. The output impedance of most smaller generator is reasonably high. that is part of the reason you see the voltage vary by a pretty noticeable amount between no load and full rated load. In the case of the honda 2000, around 20 volts between no load and full load. In our house that same 15A load will show maybe a 1 or 2 volt drop at your outlet, and no measureable drop at the meter.
soundguy: nice way to change the delay. Yes, there are times when the longer delay would be the way to go with the AC.
