SunStar ST-21CF 21 cu. ft. 12V / 24V DC Solar Chest Freezer

*MADE IN USA*


The SunStar Solar Freezer Series is specially designed to take advantage of rising solar and alternative energy markets. With a specially patented and uniquely in-house designed compressor, we made it possible and pioneered the largest market sized DC powered chest freezer. Backed by our long history in manufacturing, we believe strongly in our products and ability to craft quality and reliable products.


SunStar Solar Freezers are constructed with 4.6 inches of polyurethane insulation, making this one of the best in class in not only keeping your freezer cold, but also keeping energy consumption as low as possible. The SunStar Solar freezer also comes equipped with a built in automatic 12V/24V current switch to allow for operations for almost any battery, location, or situation.


SunStar Solar Freezers also features a galvanized steel interior for durability and longevity, a double gasket design to ensure the tightest seal possible, along with a cooling fan to enhance the life of the compressor and in turn your freezer.


SunStar Solar Freezers are designed with consumer and commercial use in mind. The philosophy behind this product is efficiency, durability, quality, and value.
