Typical size 24 flooded batteries are rated at 80 AHr so two in parallel would be 160 AHr. For max battery life, batteries should not be discharged any lower than 50% of their capability or in your case 80 AHr. A 2,000 watt MSW inverter needs to draw 170 amps from the batteries to output 2,000 watts (16.7 amps @ 120 volts). So on a good day, you might be able to draw 2,000 watts out of the batteries for 28 minutes. I have two size 24 flooded batteries and a 1,000 watt inverter. Running the frig on propane, watching one TV with DirectV receiver will deplete the battery bank to 50% in about 6 hours.
