Call for the best deal. 1-844-945-3625 SunStar Solar 8CU Chest Freezer FAQs Is this freezer DC-only, or does it also run on AC power? This model is DC-only. It runs directly off 12V or 24V DC solar systems without requiring an inverter. If you need a model that can also run on standard 115V AC grid power or solar AC, please see the SunStar Solar 15CU ST-15CF which is available in both AC and DC configurations. How much capacity does the 8CU chest freezer have? The freezer holds 227 liters (8 cubic feet). The interior measures 32.25" wide × 18.5" deep × 26" high — a practical size for RVs, remote cabins, and off-grid homes where space matters but you still need meaningful storage for game meat, groceries, or garden produce. Can it be used as a refrigerator as well as a freezer? Yes. The multi-function thermostat lets you switch between deep-freeze and refrigeration modes, giving you full flexibility over how you store your food depending on what you need at any given time. Does it work with both 12V and 24V solar systems? Yes. The unit operates across both 12V (9.6–17V) and 24V (21.3–31.5V) DC ranges. At 12V it draws approximately 4 amps, and at 24V approximately 2 amps, for a typical power draw of 55 watts — keeping your solar battery draw to a minimum. How thick is the insulation, and why does it matter? The walls feature 4.5" of polyurethane insulation. Thicker insulation means the compressor runs less frequently to maintain temperature — which directly reduces power consumption and extends the life of your solar battery bank, especially important during cloudy periods. Is this freezer difficult to move? No. Heavy-duty castors come pre-installed, making it straightforward to roll and reposition the freezer in a barn, garage, RV bay, or between outbuildings without needing to lift or drag it. What refrigerant does it use? The ST-8CF uses R134A refrigerant — a widely available, reliable refrigerant that performs consistently across a broad range of ambient temperatures suitable for off-grid environments. × Connect With Us Get expert guidance and exclusive pricing! 1-844-945-3625 📞 Call Now 💬 Chat with Us ✉️ Text Us Mon-Fri: 10am-5pm CSTAfter hours?
