 +=== Absorption refrigeration ===
  
 Absorption (ie, propane-powered ammonia cycle) fridges were popular in RVs because they used minimal power to run the ignitor, control board, fans if any.     This type of fridge had to to be quite level so the ammonia cycle cooling would work by gravity;  there is no pump.((http://www.doityourselfrv.com/know-rig-level-enough-rv-refrigerator-work-properly/))  Using one out of level could damage the $$$ cooling unit.   Absorption (ie, propane-powered ammonia cycle) fridges were popular in RVs because they used minimal power to run the ignitor, control board, fans if any.     This type of fridge had to to be quite level so the ammonia cycle cooling would work by gravity;  there is no pump.((http://www.doityourselfrv.com/know-rig-level-enough-rv-refrigerator-work-properly/))  Using one out of level could damage the $$$ cooling unit.

-==== Peltier refrigeration ====+ 
 +=== 120vac Mini-fridge === 
 + 
 +Some have reported good results with inexpensive "dorm" refrigerators, especially when external insulation is added.  
 + 
 +PRO 
 + 
 +  * inexpensive 
 +  * widely available 
 + 
 + 
 +CON 
 + 
 +  * not designed for mobile use 
 +  * typically only available in front-loading 
 +  * typically not optimized for power use 
 +  * typically not well-insulated 
 +  * requires 24/7 [[electrical:inverter|inverter]] use, with inefficiencies while running and parasitic losses while still.

 +=== Peltier refrigeration ===
  
 Peltier cooling doesn't get used much in solar setups because it uses a lot of power and does so 100% of the time.  A typical Peltier cooler might run 4-5A continuously whereas a compressor cooler might run 5A 30% of the time and turn off the rest of the time. The 100% duty cycle issue can be alleviated by wiring in [[https://amzn.to/2WJg4tu|a 12v thermostat]].((assuming it would ever get cold enough to shut off. )) Peltier cooling doesn't get used much in solar setups because it uses a lot of power and does so 100% of the time.  A typical Peltier cooler might run 4-5A continuously whereas a compressor cooler might run 5A 30% of the time and turn off the rest of the time.
