When a fridge starts, it requires an additional surge of power to overcome the initial resistance and get the compressor running. This surge in power is known as the "starting wattage" or "startup current." The starting wattage for a refrigerator can vary depending on its size, type, age, and compressor specifications.
On average, a typical household refrigerator can require around 800 to 1200 starting watts for a few seconds when it's turned on. Once the compressor is running, it settles back to its normal operating wattage, which is usually lower. The normal running wattage of a fridge can be anywhere between 100 to 800 watts, depending on the factors mentioned earlier.
It's important to consider the starting wattage when using a generator or an inverter to power a refrigerator during a power outage or in off-grid scenarios. The power source should be able to handle the starting surge to prevent any overload or damage to the electrical components of the fridge.
Keep in mind that these numbers are approximate averages and may not apply to every refrigerator model. For specific details about your fridge's power requirements, you can check the user manual or look for the label on the back or side of the refrigerator that provides information about its power consumption.
