how much capacity would a generator need to run a refridg & room a/c unit?

Answer 1

Choosing a Generator: Which Size Is Right?
Portable generators are available for power outages as well as campsite or jobsite use.

Permanently mounted stand-by generators provide automatic power when the regular power supply is interrupted. Powered by natural gas, they can power selected circuits within a few seconds of a power failure. These are wise investments for areas that may experience frequent power outages.

Depending on their wattage output, generators will run anything from a small lamp to a number of large appliances. To determine the size generator you will need, total the wattage of the maximum number of items you will be running simultaneously. For items with start up ratings higher than their run ratings, use the higher rating to determine your power requirements.

Inductive load appliances and tools such as refrigerators, washers, and power tools require additional wattage for starting the equipment. The initial load only lasts for a few seconds on startup but is very important when calculating your total wattage.


Permanent stand-by generator.
For example: running a 100 watt light bulb, a 200 watt slow cooker, a 1,200 watt refrigerator with a start up wattage of 2,900 watts and a 750 watt TV would require 3,950 watts.

Answer 2

These depend upon the size of the Fridge and A/C. On the appliances you should see an amperage and/or energy rating that should tell you what wattage is needed. Add those two numbers together then multiply that by 1.25. The generator you get should be able to produce that amount which would be enough to cover both units running at the same time and the start up surges associated with all electrical motors.

Hopes this helps!

Answer 3

Refridgerators and room aircons come in different specifications. You should read the labels (or the user guide) and look for the number infront of "Watt", and add them up, and then multiply by two (!), and that's the PEAK power for the generator you would need.
Why times 2?
Both have strong motors inside which need much more power for a short moment (power surge) to actually get started.

Answer 4

I'll assume the room air condition to be rated at 5000 BTU and needs an average of 1875 watts of power. For the refrigerator, I'll assume it needs an average of 1250 watts. So the total estimated wattage needed to power these appliances is 3125 watts. I'm going to multiply the total 3125 watts by 1.25 to get a larger wattage estimate of 3906 watts. This larger wattage estimate adds extra wattage to help avoid overloading the generator. This is the estimated size, in watts, of the generator needed to power the refrigerator and room air conditioning unit. You can choose from many appliances and get estimated wattage totals using the following generator wattage estimator.

Answer 5

most generators will do this (i.e. motorhomes )i would think one about 2Kw would be sufficient

Answer 6

5500
