Here in central Florida there is about one power failure a week. Most last a minute or two and are no problem since I have an inexpensive backup battery/power surge protector but it is pretty wimpy. We did have the power go out for a few days once when someone struck a transformer pole. We also get the occasional hurricane passing by like tropical storm Nestor is doing as I type this. Lots of rain but no wind. I decided I needed to upgrade my backup battery/power surge protector and I found a nice one with automatic voltage regulation and a nice LCD screen.

I installed it yesterday and it took all day. The problem was I have a very complex audio video system and I had to completely disassemble everything and then reassemble it correctly. It has been years in the making and there were many things about my installation the I did not like. Such as the old battery backup and my modem were both located in a cabinet and I had put a bookcase in front of the cabinet making it a hassle to get into. I relocated the new unit and my modem directly under the audio receiver and in plain site from anywhere in the room. This allow me to monitor the power and the Internet at a glance. The LCD on the backup shows all kinds of information. Input voltage, output voltage, number of minutes left on the battery, etc. I am not worried about powering the whole house, just the modem and my laptop chargers. I realize a generator might be a better option in some instances however I have no garage to store it in.
But this post is not to brag about my new toy or to recommend this particular unit. I have a question. I have the LCD on the backup set to show input voltage and I noticed something I cannot explain and I am hoping someone (such as Lou) has a good explanation. My input voltage runs pretty constantly around 118 but once I turn on the A/C the incoming voltage shoots up by about 2 volts. When I turn off the A/C it drops back down almost instantly by two volts. This is the opposite of what I would have expected. Anyone have any idea?
