A Portable Solar DC Refrigerator / Fridge 118Liters 58W DC12/24V is a highly efficient, off-grid appliance. By operating directly on direct current (DC), it avoids the 10% to 15% energy loss typically caused by converting power through an AC inverter.

Portable Solar DC Refrigerator / Fridge 118Liters 58W DC12/24V Key Specifications

The typical breakdown of a standard 118L DC 12V/24V solar refrigerator includes:

Capacity Split: Usually divided into a 78L to 79L refrigeration chamber and a 39L to 40L freezing compartment .
Power Consumption: Rated around 58W to 60W when active. Daily power consumption is roughly 0.62 kWh per 24 hours under standard operating conditions.
Temperature Range: Offers mechanical thermostat control keeping the fridge chamber at 0°C to 10°C and the freezer at -18°C or lower .
Dimensions & Weight: Measures approximately 480 x 490 x 1105 mm with a net weight of about 28 kg to 35 kg , making it relatively compact for transport.
Refrigerant: Typically relies on R134a gas coupled with thick cyclopentane insulation (often up to 70mm) to maximize cold retention.

Off-Grid Solar System Requirements

To run a 58W/118L DC fridge continuously without depleting your battery bank, you need a properly scaled off-grid solar setup:

Solar Panels: A minimum of 300W to 400W of solar panels is recommended to harvest enough energy during daytime peak sun hours to run the fridge and recharge the battery.
Battery Storage: A 100Ah to 150Ah 12V Deep Cycle Battery (preferably LiFePO4 or specialized solar gel) ensures the fridge keeps running smoothly during cloudy days and overnight.
Charge Controller: A 30A MPPT or PWM charge controller is required to safely regulate the flow of electricity from your solar panels to the battery bank.
