Please watch the whole video as I go in depth with power consumption and timing tests for the unit. This is the best unit for the money. This unit costs $550 on google shopping, whereas ARB’s 50qt unit costs $780 and Engel’s 43qt unit costing $900.
This unit is extremely energy effecient, using only about 20-30 watts per hour to mainatin 33’F. It can easily be used on a solar setup, as an emergency backup fridge/freezer, or even to go purchase perishable food items from the grocery store.
UPDATE: Edgestar has email me back and has said the two extra yellow wires are for another temperature sensor which is not supported in this model. Just disregard the wires.
