What is the current draw (amps or watts) of both the inverter and the fridge?
I assume EACH battery is 12v 160AH - wired in parallel gives 320AH capacity. You can't use all of that of course - don't want to run the batteries all the way down - even deep cycles...
Based on draw, can determine how long it SHOULD be able to run on good batteries...
You will find a lot of threads complaining about Harris batteries - but we can do the math to see how it is performing.
If you have the space - adding additional batteries can be done... but likely looking at a full set.
