As a seasoned veteran of many storms, I bet you guys will probably never really have as much use for your generators as you now think you will. I was without power for almost a month after Hurricane Andrew, and it was only because one of my neighbors went to the local motel where an out of state power restoration crew was resting between shifts with a fistful of $$ that we got power when we did. After that, I got a whole house generator (and 14kw is plenty for two central A/C's, all the lights and hot water heater as long as they don't all turn on at the same time). I would say that the longest I have ever had it run is two days since then. I have 70 gallons of diesel fuel on and under the trailer it is on (an installation on wheels is considered a temporary installation and has much easier zoning requirements here even though I would have to tear down my wall to move it). That will run it basically for three days (about one gph). I try to keep the tanks full and keep a couple of 5 gallon tanks full also. Since the Andrew debacle the power company has done a great job with hardening our power grid so we have been through a few major storms with little or no outages. Some power lines have been buried, some wooden poles have been replaced with concrete but the single most important contribution to maintaining a normal lifestyle was the County government passing a regulation that ALL gas stations (and hospitals and shelters) MUST have a standby generator in order to be in business. When all else fails, we still know we can go and buy gas and diesel fuel at the corner. Major factor. I am still very glad I have the generator and even if it only goes on for a couple of hours due to a blown transformer, my wife is really glad we have it too. It is totally hands off. It has a big panel made in Spain in my garage that senses when the utility power goes off and thirty seconds later kicks in and if the power comes back on it shuts off in 60 seconds. It has been flawless and it "exercises" itself every Saturday morning for 15 minutes to make sure everything is ready and waiting. The guy who installed it comes by once a year and changes the oil and checks the state of the battery.
