SunStar Solar DC/AC 10CU Refrigerator
The Only Multi-Voltage Dual-Compressor Upright Solar Fridge in North America
The SunStar Solar 10CU Refrigerator is a 100% American-made, dual-compressor upright solar refrigerator built for both off-grid and grid-connected use. It runs on 12V or 24V DC solar power and 115V AC simultaneously — the only multi-voltage, dual-compressor model of its kind in North America.
With two independently controlled compartments, 4" polyurethane insulation, and a typical draw of just 55 watts, it's the smart choice for cabins, RVs, boats, and sustainable homes that refuse to compromise on performance or efficiency.
- ✓ 100% Made in the USA
- ✓ 10 Cu Ft / 278 Liter Capacity (Two Compartments)

One-of-a-Kind Off-Grid Performance
Dual Power — DC & AC Simultaneously
Connect to 12V or 24V DC solar and 115V AC at the same time. The unit automatically manages both inputs, giving you seamless, uninterrupted operation whether you're on solar, grid power, or switching between the two.
Exclusive Keota Dual Compressor
The proprietary Keota dual compressor system independently controls each compartment, delivering maximum efficiency and reliability. It's what makes this the only multi-voltage, dual-compressor upright solar refrigerator available in North America.
Built for the Way You Live Off-Grid
Independent Dual-Zone Temperature Control
Each compartment has its own independent thermostat. The top compartment (6.6 cu ft) is a full refrigerator; the bottom (3.2 cu ft) functions as either a refrigerator or a freezer — your choice.
Auto Defrost & Interior LED Lighting
The top compartment features automatic defrost for hands-free maintenance. Both compartments have interior LED lights for clear visibility, plus a fault LED indicator for fast, easy troubleshooting.
Adjustable Shelves & Reversible Door
Flexible adjustable shelving lets you organize produce, beverages, and containers exactly how you need. The reversible door accommodates any kitchen, cabin, or RV layout without compromise.
Mobile, Stable & Easy to Place
Wheel castors make repositioning simple. Front adjustable leveling legs keep the unit perfectly stable on uneven floors — common in cabins, RVs, and boats. Built with a durable corrosion-resistant exterior.

SunStar Solar 10CU Refrigerator FAQs
What makes this refrigerator unique compared to other solar fridges?
The SunStar 10CU is the only multi-voltage, dual-compressor upright solar/DC refrigerator available in North America. It features a proprietary Keota dual compressor system that independently controls each compartment, supports simultaneous DC and AC power input, and is 100% made in the USA — a combination no other model on the market offers.
Can it run on DC and AC power at the same time?
Yes. The 10CU supports simultaneous connection to both DC solar (12V or 24V) and 115V AC. This means you can stay connected to your solar system while also plugged into grid power, giving you seamless, uninterrupted cooling without manually switching between sources.
What is the Keota dual compressor system?
The Keota dual compressor is a proprietary system exclusive to SunStar Solar. By using two independent compressors — one per compartment — it delivers more efficient, reliable cooling than a shared single-compressor design. Each compartment maintains its own temperature independently, and the system is specifically engineered for low-power solar environments.
What are the two compartments used for?
The top compartment (6.6 cu ft) functions as a standard refrigerator with automatic defrost. The bottom compartment (3.2 cu ft) is versatile — it can be configured as either a second refrigerator section or a freezer, controlled by its own independent thermostat. Total capacity is 278 liters (9.8 cu ft).
How energy-efficient is it?
The 10CU draws a typical 55 watts — 4.3A at 12V or 2.2A at 24V — making it extremely light on your solar battery bank. Combined with 4" polyurethane insulation, it maintains stable temperatures efficiently even during low-sun periods.
Does the DC input work with both 12V and 24V systems?
Yes. The unit automatically detects and operates across both 12V (10.6–17V) and 24V (21.3–31.5V) DC ranges. No manual switching is required, making it compatible with the majority of residential and mobile solar setups.
Is the door reversible?
Yes. The door is fully reversible, allowing you to configure the hinge side to suit your kitchen, cabin, RV, or boat layout — a practical detail that matters in tight spaces.
What refrigerant does the 10CU use?
The 10CU uses R600a (isobutane) refrigerant — a highly efficient, environmentally friendly refrigerant with low global warming potential that performs exceptionally well in high-efficiency solar applications.
