What size generator do I need to run my refrigerator?
To determine the size generator needed for your refrigerator, first, check the appliance’s wattage rating, which is usually found on a label inside the fridge or in the user manual. On average, a standard refrigerator requires between 600 to 800 watts for continuous operation. However, when starting up, refrigerators can draw significantly more power—typically around 2,000 to 3,000 watts. Therefore, it’s important to choose a generator that can handle both the running and starting wattage.
To calculate the appropriate generator size, add the starting wattage to the running wattage. It’s also wise to account for any other appliances you may want to use simultaneously. For instance, if your refrigerator needs 800 watts to run but requires 2,400 watts to start, you should consider a generator with at least a 2,400-watt capacity to ensure it operates efficiently and reliably.
How do I find the starting and running wattage of my refrigerator?
Finding the starting and running wattage of your refrigerator can be done through a few simple methods. The first step is to check the manufacturer’s label located on the back or side of the refrigerator, where wattage information is often specified. If this label isn’t visible, you can often find the information within the user manual or by searching the model number online.
If neither of those methods is viable, using a wattage meter can provide an accurate measurement.
