SunStar Solar DC/AC 16CU Refrigerator
The Largest Upright Solar Refrigerator in North America
The SunStar Solar 16CU Refrigerator is a high-capacity, full-size off-grid refrigerator — made in the USA and built for serious off-grid living. With 16 cubic feet of dual-compartment storage and simultaneous DC/AC capability, it's the most capable solar-powered upright fridge available in North America today.
Powered by the exclusive Keota dual independent compressor system with separate thermostats for each compartment, the 16CU delivers precise, reliable cooling across two independently controlled zones — all while drawing a typical 60 watts from your 12V or 24V DC solar bank, or from 115V AC grid power.
- ✓ Made in the USA
- ✓ 16 Cu Ft / 454 Liter Dual-Compartment Capacity
- ✓ Exclusive Keota Dual Independent Compressor System
- ✓ 4" Polyurethane Wall Insulation
- ✓ DC Solar (12V/24V) & 115V AC — Simultaneous Dual Input
Two Compartments. One Powerhouse Refrigerator.
Keota Dual Independent Compressors
Two separate compressors — one per compartment — mean each zone maintains its own precise temperature independently. If one compressor ever needs service, the other compartment keeps running without interruption.
DC Solar & AC Grid — Both at Once
Run on 12V or 24V DC solar power, 115V AC grid power, or both simultaneously. Seamlessly transitions between power sources — ideal for hybrid setups where you want solar savings with grid backup.
Built for Full-Time Off-Grid Living
Top Compartment: Fridge or Freezer
The upper zone (4.8 Cu Ft) is fully configurable — set it as a refrigerator for produce and drinks, or switch it to freezer mode for meat and long-term storage. Your choice, any time.
Bottom Compartment: Auto Defrost
The spacious lower zone (11.2 Cu Ft) features automatic defrost so you're never manually clearing ice buildup. More convenience, less maintenance — even in humid off-grid environments.
Interior LED Lights & Fault Indicator
Both compartments feature interior LED lighting for easy access in any light condition. A dedicated fault LED makes troubleshooting quick and intuitive, even far from the nearest service center.
Reversible Door & Adjustable Shelving
The reversible door lets you configure the fridge to fit your space — opening left or right as needed. Adjustable shelving accommodates tall items and flexible storage layouts for any household.
Massive Capacity. Organized Storage.
With a combined 454 liters across two independently controlled compartments, the 16CU is sized for families and serious homesteaders. The top zone (W 23" × H 14.5" × D 24.75") is perfect for fresh produce, dairy, and beverages. The generous lower compartment (W 23" × H 35.5" × D 24.75") handles bulk groceries, meal prep, and long-term storage with room to spare.
Adjustable shelving, generous storage bins, and full interior LED lighting in both zones make it easy to stay organized — whether you're stocking up for a month off-grid or managing daily household needs.
Built Tough. Built to Last.
The 16CU is engineered with a durable, corrosion-resistant exterior designed to stand up to the demands of off-grid living — from temperature swings to high-humidity environments. Front adjustable levelling legs and pre-installed wheel castors make installation and repositioning effortless on any surface.
Sun Star's commitment to quality shines through in every detail — from premium materials and rigorous testing to reliable, long-lasting performance that customers can count on for years to come.

SunStar Solar 16CU Refrigerator FAQs
What makes this the largest upright solar refrigerator in North America?
At 16 cubic feet (454 liters) of dual-compartment capacity in a full-size upright form factor, the SunStar 16CU is the largest DC solar-powered upright refrigerator available in North America. Most solar-optimized upright fridges top out at 10 cubic feet, making the 16CU the go-to choice for families, homesteads, and commercial off-grid operations that need full household-scale refrigeration without relying on AC grid power.
How do the two compartments work independently?
Each compartment has its own dedicated Keota compressor and its own thermostat, meaning you control the top and bottom zones entirely separately. The top compartment (4.8 Cu Ft) can be set as either a refrigerator or a freezer. The bottom compartment (11.2 Cu Ft) operates as a refrigerator with automatic defrost. You can set them to completely different temperatures at the same time.
Can it run on DC solar and AC grid power at the same time?
Yes. The 16CU supports simultaneous DC and AC input, making it ideal for hybrid systems where you want to prioritize solar energy but keep AC as a seamless backup. It auto-operates at 12V or 24V DC, and accepts 115V AC — all in the same unit.
What is the typical power draw on solar?
The 16CU draws approximately 60 watts, or 5 amps at 12V and 2.5 amps at 24V. Given its 16 cubic foot capacity, this is a remarkably efficient power draw — made possible by the 4" polyurethane insulation and the efficiency of the Keota dual compressor system.
What is the Keota dual compressor system?
The Keota system uses two independent compressors — one assigned to each compartment — rather than a single shared compressor. This means each zone maintains its temperature precisely without influencing the other. It also adds redundancy: if one compressor ever needs maintenance, the other compartment continues operating normally.
Does the bottom compartment defrost automatically?
Yes. The bottom compartment (11.2 Cu Ft) features automatic defrost, so you never have to manually remove ice buildup. The top compartment does not include auto defrost, which is standard for freezer-capable compartments to maintain colder and more consistent temperatures.
Is the door reversible?
Yes. The door can be configured to open from either the left or right side, giving you full flexibility to position the refrigerator optimally within your kitchen, utility room, or off-grid space regardless of wall and cabinet layout.
What refrigerant does it use?
The 16CU uses R600a (isobutane) refrigerant — a high-efficiency, low global-warming-potential refrigerant that provides excellent cooling performance and is well-suited for off-grid environments with variable ambient temperatures.
