Importance of Solar Energy in Nigeria

In a country where grid power is often unreliable, solar-powered appliances provide a vital lifeline for food preservation. Solar refrigeration is no longer a luxury but a necessity for escaping the high costs of generator fuel. By utilizing free energy from the sun, the SMK 90L fridge ensures your essentials stay preserved 24/7 without adding a kobo to your monthly utility bills.

Advantages of Lithium Batteries Over Traditional Batteries

To get the most out of your solar fridge, pairing it with a Lithium (LiFePO4) battery is highly recommended:

1. Longevity: Lithium batteries last 10+ years, compared to the 2–3 year lifespan of lead-acid batteries.
2. Consistent Cooling: Lithium maintains a stable voltage output, ensuring the fridge compressor runs smoothly even as the battery drains.
3. Faster Recharge: Lithium accepts solar current much faster, which is critical during short sunny windows.

Key Features of the SMK 90L Solar Fridge

1. Dual Voltage: Works automatically on both 12V and 24V DC systems.
2. Low Power Consumption: Rated at approximately 20W – 80W depending on the cooling cycle, significantly reducing the number of solar panels needed.
3. Extra-Thick Insulation: Features high-density foaming to retain cold air for hours even after the sun goes down.
4. CFC-Free Refrigerant: Environmentally friendly R134a cooling agent.
