SMK Solar Freezers: Reliable Off-Grid Cooling for Nigeria
In a climate as demanding as ours, keeping food and medicine fresh without a reliable national grid is a major challenge. SMK Solar Freezers are the definitive answer for Nigerian households, rural clinics, and small business owners. Unlike standard chest freezers that require heavy-duty inverters and massive battery banks, SMK units are engineered for high efficiency and direct solar compatibility.
At Kara, we offer the full range of SMK models, including the 110-liter DCF110, the mid-sized 200-liter DCF208, and the industrial-scale 300-liter DCF308.
The Direct DC Advantage: Why SMK is Different
SMK Solar Freezers are primarily Direct DC (Direct Current) appliances. While most home appliances require an inverter to convert solar power into AC (Alternating Current), SMK freezers use a specialized DC compressor that connects directly to your solar battery.
- Maximum Efficiency: By eliminating the inverter conversion process, you avoid a 10-15% energy loss. This means your freezer stays colder for longer on a smaller battery.
- Lower Initial Cost: Since you don't need a large inverter to handle the compressor’s "kick-start" surge, your overall solar power system becomes more affordable.
- Dual Compatibility: For added flexibility, all SMK models are hybrid-ready, allowing them to run on DC 12V/24V (solar) and AC 110V-240V (NEPA or Generator) power.
Key Features of SMK Solar Freezers
- Ultra-Thick 80mm Insulation: SMK uses high-density polyurethane foam that is significantly thicker than standard freezers. This ensures your items stay frozen for up to 48 hours even if the power source is disconnected.
- Low Power Consumption: These units are rated between 58W and 105W (depending on the model), making them some of the most energy-efficient freezers available in Nigeria.
- Tropicalized Design: Equipped with outside condensers and silent, maintenance-free compressors, they are built to perform in temperatures exceeding 40°C.
- Advanced Protection: Built-in low-voltage disconnect and automatic electrode direction protection safeguard the machine and your batteries from electrical faults.
Choosing the Right Size for Your Needs
- SMK 110L (DCF110): Ideal for small families or storing temperature-sensitive medicines in clinics. Requires a minimum 150W solar panel.
- SMK 200L (DCF208): The perfect "all-rounder" for a standard 4-bedroom household. Recommended with a 300W panel array and a 200Ah battery.
- SMK 300L (DCF308): Best for commercial use in shops, restaurants, or large catering businesses. Requires a 450W–600W solar setup for 24/7 performance.
SMK Solar Freezer Price in Nigeria
The price of SMK solar freezers at Kara is highly competitive, ranging from ₦589,000 for the 110L model to ₦914,500 for the 300L unit. While the initial cost is higher than a standard freezer, the zero monthly electricity bill and the elimination of fuel costs for generators make it a much cheaper investment over its 10-15 year lifespan.

Frequently Asked Questions (FAQ)
Q: Do I need an inverter to run an SMK Solar Freezer?
A: No. SMK freezers run directly on 12V or 24V DC power from your battery. However, they can also use an AC socket if you have power from the grid.
Q: How many solar panels do I need?
A: For the 110L model, a 150W panel is enough. For the 200L and 300L models, we recommend between 300W and 600W of monocrystalline solar panels for best results.
Q: Can I use a regular car battery?
A: It is not recommended. For the best performance and lifespan, use a Deep Cycle Gel or Lithium (LiFePO4) battery.
Q: How long does it stay cold during the night?
A: Thanks to the 80mm insulation, if the freezer is closed, it will stay frozen throughout the night without consuming much power from the battery.
