We are in Naples, FL and have only 30 amp power at the pedestal. Today was the first really hot day since we got here, so we had to run the living room a/c until it cooled down in the evening. We went out to dinner, leaving the LR a/c on, set high, so it would be relatively comfortable when we returned.
When we got back, we found the a/c off, and all the rest of the 120 requirements being powered by the inverter charger.
I turned the power pedestal back on, and immediately the Leg 2 was using 23 amps of the 30, which I assume was the inverter now charging the batteries back up. After a little while the batteries were still on Bulk, and the amps on leg 2 were still 23. Suddenly, the refrigerator motor came on, and the amps on leg 1 went up to 10, and of course with the 23 on leg 2, we soon experienced another shutdown from the power pedestal.
During this time the AGS kicked the generator on in an effort to provide 50 amp to recharge the batteries, and run the refrigerator. I am not comfortable running the generator while neighbors are either sleeping or having quiet time, so I shut it off, unplugged the refrigerator, and as I write this, the amp usage on leg 1 is zero, and the usage on leg 2 is still 22-23, although the batteries are now almost at float.
Is there a setting in the inverter I can use to inform the system about the max of 30 amp, and even if I set it to the required setting, am I still susceptible to the experience we had today?
When the batteries get to float, will I see a drop in amp usage by the inverter for charging the batteries? If that is so, I should be able to plug the fridge back in, knowing we will not use more than a total of 15 amps overnight. Is my assumption correct?
Thanks in advance for any thoughts.

P.S. We have a Xantrex 3000W pure sine wave inverter/charger with a AGS module.
