SunStar 21CU Solar DC Chest Freezer ST-21CF
Engineered for off‑grid reliability, the SunStar 21CU Solar DC Chest Freezer delivers deep freezer performance in a compact, all‑weather package. Made in the USA with Amish-quality craftsmanship in Indiana, this heavy‑duty unit is designed for remote cabins, RVs, solar installations, or anywhere dependable DC cooling is required.
Performance specifications: 12V or 24V automatic operation with a typical draw of 105 watts. The 4.6-inch polyurethane wall insulation and a double insulated lid gasket combine to minimize heat ingress and maximize efficiency. A multi‑function thermostat allows the unit to operate as a 100% freezer or 100% refrigerator, while the built‑in lid light and dedicated operating lights aid troubleshooting. The freezer ships with heavy‑duty castors for easy relocation and placement on level surfaces.
Safety and reliability: energy‑efficient construction with robust insulation, a sealed lid assembly, and precise temperature control reduce energy use and thermal cycling in off‑grid environments. This model is backed by a 2 Year Performance Warranty, reflecting SunStar’s commitment to long‑term reliability.
Installation and maintenance: designed for off‑grid DC power but compatible with a Kedron™ Power Converter for 120V AC to 24V DC adapters. Install on a level, vibration‑free surface; ensure adequate ventilation around electrical components. Maintenance is minimized by the unit’s solid insulation and gasket integrity; periodic verification of the seal and thermostat function is recommended.
Warranty and service: 2 Year Performance Warranty. For reference materials, download: Brochure, Owners Manual, Specifications. Optional accessories include Kedron™ Power Converter for cross‑compatibility with AC power sources.
