I have been having troubles with more than about 30 minutes on the inverter with the fridge, so have been wondering the same thing for a couple of months. The batteries were new in 2017, 2 under the step in the battery compartment, and a 3rd added in the storage compartment with the inverter. I did notice the other day that 2 of the batteries are starting batteries and the 3rd is a deep cycle, all 12V. Could the starting batteries be causing part of the issue? It's pretty frustrating that the inverter starts alarming very soon after switching from shore power to battery.

Sounds like the wrong type of batteries are being used for the wrong application. Your starting (chassis) battery should be a 12V starting battery, but the house batteries should be deep cycle (either 6V or 12V.) You may want to consider replacing the house batteries with good deep cycle batteries, and move the starting battery to the chassis battery wiring. If they are sealed lead acid batteries, you may also want to check their water levels and top them off (cover the plates) every so often with distilled water. Constant charging tends to wreck SLA batteries as the fluid boils off and the level goes down, uncovering the lead plates and making them less effective. If you choose to replace them, I would recommend AGM (absorbed glass mat) deep cycle batteries as they are pretty much no maintenance batteries.
