Some simple tests should show that your batteries have failed.
Either there is an internal open or several cells are shorted, causing the inverter to shut down.
This could be due to a corroded connection too or to a failed inverter.
In addition to some voltage checks, a good place to start would be to check the water in the batteries (you did do that every 4 weeks or so, right?) and connect an external charger to them for a while.
After you get the main problem solved, you should check the float voltage output of your converter/charger. If it is too high it can damage the batteries over a long period.
