how many watts do you need to run an air compressor?
605151
Heavy-duty compressors operate on 220-volt current and require special wiring and outlets. A 110-volt compressor drawing 15 amps uses 1,650 watts (110 volts x 15 amps), while a 220-volt compressor drawing 15 amps consumes 3,300 watts (220 volts x 15 amps).

For example, if you want a generator to run a refrigerator and a freezer, the wattage (table 2) of the refrigerator would be 800 and the freezer would be 1,000. To select the correct size generator, you decide if both refrigerator and freezer are to start at the same time. If so, you would need (1,800 X 4) 7,200 watts.

In this case, your RV generator needs a minimum of 2270 watts if you turn on everything at once and then 1770 watts continuous output to run everything. Throw in a few light bulbs, occasional cup of coffee and you'll need at least 2500 starting watts and 2000 watts of running capacity to run things in the winter.

A 2-ton AC at this SEER rating is approximately 15 amps; 3-tons is 18 amps; 4-tons is 21 amps. Next, calculate the wattage consumed. A typical whole-home air conditioner uses a 240-volt power outlet. Multiply the amps by 240 watts, which equals 4,320 watts.

However, most will consume in between 1 amp and 6 amps (with 2.5 amps being fairly average) an hour when running. However, a fridge won't usually run 100% of the time, so it only pulls that current when the compressor comes on. Most fridges are loud enough for you to hear them within a few metres.
