Call for the best deal. 1-844-945-3625 SunStar Solar Chest Freezer FAQs What is the difference between the AC and DC models? The AC model (ST-15CF-AC) runs on 115V AC / 60 Hz power, making it compatible with both standard grid electricity and solar-sourced AC power through an inverter. The DC model (ST-15CF-DC) connects directly to 12V or 24V DC solar systems — no inverter required — making it ideal for fully off-grid setups like remote cabins, RVs, or boats. How much capacity does the ST-15CF have? Both the AC and DC models offer 445 liters (15.7 cubic feet) of storage space. The interior measures 54.25" wide × 19.5" deep × 27.375" high, giving you plenty of room for bulk groceries, large game, garden produce, or emergency food supplies. Can the SunStar Chest Freezer also be used as a refrigerator? Yes. The multi-function thermostat lets you switch between deep-freeze and refrigeration modes, giving you flexibility to store either frozen goods or fresh produce depending on your needs at any time. How energy-efficient is it on a solar system? Both models are engineered for super-high efficiency. The AC model draws approximately 80 watts (0.69A) and the DC model draws approximately 90 watts under typical operating conditions. The 4.6" polyurethane wall insulation dramatically reduces compressor run time, minimizing the draw on your solar battery bank. Does the DC model work with both 12V and 24V systems? Yes. The DC model features automatic 12V or 24V operation — it detects your system voltage automatically, so there is no manual switching required. This makes it compatible with the majority of solar setups. Is this freezer difficult to move or reposition? No. The ST-15CF comes with heavy-duty castors pre-installed at the factory, making it easy to roll and reposition despite its large size. This is especially useful in barn, garage, or outbuilding installations where you may occasionally need to move it. What refrigerant does the ST-15CF use? Both models use R134A refrigerant, a widely available and well-understood refrigerant that supports reliable operation across a broad range of ambient temperatures. × Connect With Us Get expert guidance on AC vs DC and exclusive pricing! 1-844-945-3625 📞 Call Now 💬 Chat with Us ✉️ Text Us Mon-Fri: 10am-5pm CSTAfter hours?
