We have the largest solar chest freezer powered by 21 cubic feet of DC power. All our solar chest freezers of 9, 14, and 21 cubic feet have plenty of storage space. With a special DC compressor, sealant technology, and 4.5-inch polyurethane insulation layer, the solar chest freezer consumes the least energy compared with ordinary equipment. It can run without an inverter; these solar chest freezers can be directly powered by batteries.

　　All of our solar chest freezer models are built from the ground up and connected to direct current, which is the energy produced by solar panels. This means having a DC dedicated compressor and module, and a thicker cable to handle DC power. Our solar chiller can use a 220-watt panel and two deep-cycle batteries to run, so you can not only save the cost of the inverter but also save the cost of the panel and battery, as well as the space they occupy.

　　The solar chest freezer series also uses powder-coated galvanized steel inside, which is durable. The double gasket design can ensure the tightest possible freezer seal, and the powerful cooling fan can extend the service life of the compressor, thereby extending your freezer's Long service life. All our solar appliances are equipped with automatic voltage detection switches, so your 12-volt refrigerator can be perfectly switched to a 24-volt refrigerator.

　　DC chest freezer is also our product, welcome to consult and purchase.
