The 30 gallon generator tank lasted from Thursday about 4 PM until Saturday around 6 PM, about 50 hours. It averaged a 30 to 40 amp load in the day with all the AC's on and about 20 amps at night. A little over 1/2 gallon an hour.
I put 20 gallons in the 40 gallon pump tank and it only registered 1/4 full on the gauge. After I transferred this fuel over to the generator tank I fired her back up until 2 PM Sunday. So I basically ran the generator for almost 72 hours straight.
The only problem I had was I don't think the load management controls or recognizes any items not on the panel... WH & AC's.
With everything running lights, TV's, AC's (30 to 40 amps)... when I plugged in a roster oven outside the load management turned off the generator. It seems the start up draw from the roster oven on top of everything else took the generator over capacity and I guess the the exterior GFI outlet is not tied into the load management so it could not control that load. It did not trip the breakers on the panel or front of the generator... it powered off the generator.
I'm going to view this as a good thing!!!
After I lightened the load by switching the fridge & WH to propane and turned off the garage AC, I was able to use the roster oven without any other problems.
While I'm talking about what I learnt this long weekend I'll include the best set up I found on the AC's. Forget about the garage AC as it's non ducted and behind a closed door and worked well on it's own. The inside temperature between my main area and bedroom would read up to 10 degrees apart. So with all the vents open and both AC's running set three degrees apart (PDI recommendation) the bedroom was an icebox & the AC would shut off while the main area wouldn't cool down below about 80 degrees with the temps pushing 100 outside.
If I closed all the vents in the bedroom, bath & garage with only the main vents open and set the bedroom AC 10 degrees below the main it kept the bedroom AC on forcing air into the ducts and helped cool the living area better getting down in the low 70's, and the bedroom/bath was still like an icebox.
