15 Cu Ft 425 Liter Capacity


AC & DC Available Models


4.6\" Wall Insulation


USA Made Quality Built

Engineered for True Off-Grid Performance

Solar-Ready Design

The DC model runs directly off 12V or 24V solar systems with automatic voltage detection. The AC model supports both grid power and solar-sourced AC power for maximum flexibility.

Superior Insulation

A massive 4.6\" polyurethane wall insulation keeps temperatures stable and dramatically reduces compressor run time — maximizing energy efficiency and minimizing draw on your solar bank.

Built for the Way You Live Off-Grid

Dual-Mode: Freeze or Refrigerate

The multi-function thermostat lets you switch between deep-freeze and refrigeration modes, giving you complete control over how you store your food, produce, or game meat.

Built-In Lid Light & Status Indicators

A convenient built-in lid light illuminates the interior for easy access in low light. Dedicated operating indicator lights make troubleshooting fast and intuitive, even in remote settings.

High Efficiency, Low Power Draw

The super-high-efficiency compressor is optimized for solar operation. The AC model draws just 80W at 0.69A; the DC model draws 90W — both designed to run reliably even during low-sun periods.

Mobile & Heavy-Duty

Pre-installed heavy-duty castors let you move this large-capacity freezer with ease — indoors, in a barn, or between outbuildings. Built with a corrosion-resistant exterior that withstands the elements.

Massive Capacity. Precision Cold.

The ST-15CF opens wide for easy loading of bulk groceries, garden harvest, large game, or emergency food supplies. The interior is sized at 54.25\" W × 19.5\" D × 27.375\" H — spacious enough for serious long-term storage.

Consistent temperature is maintained even during power fluctuations thanks to the reinforced insulation and solar-optimized compressor, ensuring your food stays safe no matter what the weather does.
