Curious as to the in-rush current causing this tripping. As you say, 1/0 wire is never going to be any issue.
What's the DC voltage? Are the 6X6 volt batteries all in series? If so, this can possibly be a "bottleneck" for peak amps.
Larry has his 4X6 volt batteries in series but they are physically huge in size with equally huge lead plates inside, but only has #3 wire size jumpers throughout.
How did you make a chest freezer be a fridge? Did you just make/allow a higher temp setpoint on it?
Yea, it's a Xantrex Pro SW with 4000 amp surge but as a later poster confirmed, fridges and freezers can, on occasion, demand huge starting currents. I even went as far as to put one of the 'miracle' surge capacitors on the freezer but no go. It only happens once a week or two but you need an alarm to warn you that the thing has tripped.
As for the freezer to fridge conversion, I bought a digital temperature control from Aliexpress in China for around $12 including shipping! Wired it to a solid state relay for higher current (also from Aliexpress) and enclosed the whole thing. Ran the sensor into the freezer/fridge and taped it to a bottle of water for a more constant temp source. Works great to keep my beverages and a few other things at 35 degrees. Since it's a chest freezer, opening the door doesn't lose all the cold. It cycles maybe once every 1/2 hour to hour for 5 minutes max sitting out in the 100 degree garage.

Oh, I have my 6 batteries wired as 12 volt and three sets in parallel. It can go about 3 days without sun. Gotta watch the specific gravity though as getting below 50% on any deep cycle battery is death on longevity.
