What size of inverter do you have?
How far is the inverter from the battery?
What is your cable size?
I was told to make the distance from battery -> inverter less than 6 feet and use the largest cable I could afford. I would suggest trying to keep it less than 3 ft and use nothing smaller than 1/0.
The refrigerator most likely surges on startup. Sounds like you have 4 batteries which should be able to provide the current surge at startup.
