Battery Bank Wire Size
I built my battery bank four 12 volt deep cycle batteries with 340 amp hours. At the time I had not added the 500 watts of solar and a 2000 watt inverter that I now have. At the time I used 2 ...

Any thoughts.
Batteries are rated at a draw of 25 amp-hours each. So with 4--expect not much voltage drop until reaching 100 amps.
Inverting eats up 12% of the energy, so at 88 amps voltage drop may start showing up.
My microwave draws 166 amps. At the moment the battery bank is 556 amp-hours (but is 4 years old). I get pretty much the same results as you. 11.4 volts under load.
