Product review (3 stars): For dry areas with no lightning only......
If you live in Florida or any other area with high lightning probability or high humidity - look at other options.  We purchased the largest Sundanzer fridge and later two 8 cu ft freezers.  Bought the fridge first.  Then the two freezers as the fridge seemed to work well with our small solar system. The refrigerant lines on the fridge failed shortly after the warranty expired as mentioned by others here.  Was told it was due to high humidity and condensation.  The two freezers lasted longer because they were frozen with no liquid accumulation in the bottom.  Last week we had a very near lightning stike that induced current backfeed in many of our appliances and solar system.  Our two freezers were reduced to coolers with lights.  Such a large investment and too much food to find a new place to keep frozen.  Composted a lot of thawed food.  Looking into dehydration for a possible answer.  Sundanzer suggests shipping the units back to them for repair.
 Cheaper to buy a 110V freezer and run a generator when needed - I can get the generator or 110 freezer repaired locally.

Addendum: Currently communicating with Billy Amos of Sundanzer.  He says we can replace the controller module on the ones that have a Danfos or Sencop Compressor - not a difficult repair and that they can be ordered through our dealer.  One of our freezers is not a Danfos or Sencop, so I am waiting to hear if the controller module for that unit can be obtained as well.  Will update as I learn more about this.  The freezers have served us well until now....

The continuing saga - Billy Amos at Sundanzer advised that the only component that is usually damaged by lightning is easily replaced by most users with some knowledge of simple electrical devices.  The control module was available for both units we purchased and I was able to order through The Solar Biz, where we purchased our freezers. Hopefully, they will make our appliances functional again.

7/6/15 Happy to report the order was made for the controllers for the two freezers that had stopped functioning.  Today my husband was able to replace one of the bad ones with the new one and the unit is now working.  Will replace the other tomorrow.  Service from both Solar Biz and Sundanzer was courteous and prompt.  Fortunately we are accustomed to making our own repairs when possible so all is back to normal.  End of review.
