How long can a Yeti 300 power a small refrigerator?

Understanding Small Refrigerator Energy Consumption

When it comes to powering a small refrigerator, energy consumption varies depending on the size and type of refrigerator. A typical small refrigerator consumes around 100-150 watts of power. For example, the Engel FR120F, a popular small refrigerator for camping and overlanding, consumes 110 watts of power.

Calculating Power Requirements

To calculate how long the Yeti 300 can power a small refrigerator, we need to consider the Yeti 300’s battery capacity, which is 300Wh. We can use the power consumption of the refrigerator (110 watts) to estimate the battery drain rate. Assuming the refrigerator operates at an average efficiency of 85% (a reasonable estimate for a small refrigerator), the actual power consumption would be 110 watts / 0.85 = 129 watts. Now, let’s divide the Yeti 300’s battery capacity (300Wh) by the refrigerator’s power consumption (129 watts): 300Wh / 129 watts = 2.33 hours. However, this calculation does not take into account the Yeti 300’s ability to recharge its batteries from the Goal Zero Boulder 30 solar panel. With proper solar charging, the battery capacity can be replenished, extending the overall runtime.

Maximizing Runtime with Solar Charging

To maximize the runtime of the Yeti 300 and the small refrigerator, it’s essential to use a high-efficiency solar panel like the Goal Zero Boulder 30. This panel can recharge the Yeti 300’s battery at a rate of 30 watts per hour. Assuming the refrigerator consumes 129 watts of power, we can calculate the net energy consumption: 129 watts - 30 watts (solar recharge) = 99 watts. Now, let’s recalculate the runtime: 300Wh (battery capacity) / 99 watts = 3.03 hours. With proper solar charging, the Yeti 300 can extend the runtime of the small refrigerator to approximately 15-20 hours, depending on the specific conditions and usage patterns.
