I did a generic load test. I used a electric stove amd was only able to to pull 60% and it ran fine. (So the only thing that you KNOW for sure, is that it will carry 60% load no problem. That's 6 KW. Its safe to say, that most homes without a big ol Air Con can be run with a 5KW gen set. simply hooking it up to the house, and turning on things isn't really a scientific was to check out what the gen set will carry for a load. Probably 99% of a house load is a steady draw load. Doesn't go up much, doesn't go down much. A constant load is easy to carry. You need to figure out what is the total load of your house. Then figure out what the start up draw of the air con is.) Smoked a small bit but didn't appear to be soot. This is the same gen that carries low oil pressure after being ran for about an hour. So I figured that it was connected. As for the age of the a/c unit it was installed on 2001. It starts and runs fine on utility power. (Why should it not it start up on Utility Power? The only limiting factor is what size is the circuit breaker that is in line between Utility Power and air con. Not the rest of the house. Have you looked to see what size it is?) The well pump, dryer, stove, water heater and all other electrical items function as they should with gen set running. I did some sime looking over everything and decided to opt for the window unit and grabbed one from the garage and tried it in conjunction with miltiple loads and everything seemed fine. (Maybe try turning every other thing off in the house, by opening the circuit breakers on everything BUT the air con, then reading the Amp draw for JUST the air con. Then you can see the max draw, and normal draw.) So to sum things up. The gen set has output as needed, loaded up to 60% per gen set gauge, (This gauge is about as trustworthy as a used car salesman. Get a GOOD meter. It will pay for itself.) Hz and amps have not been confirmed from known good meter, hooked up to house and grounded, powers everything with various loads and seem to run and keep rpm stable during load changes. Only issue is it won't power a/c unit on without any other load. (This leads one to think that A: the gen set has a problem, or, B: the air con needs a soft start upgrade. And 18 years old air con is not the most energy efficient thing in the world.) The tag on the a/c unit is partially unreadable. I can read the FRA and FLA of 34 and 17amp and rated volts are 208/220. I understand with certain testing not done to confirm is a risk but what do you do when a hurricane is coming your way.
