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.
What size generator do i need to run fridge and freezer.
Wattage engine run time starting mobility.
1 2 hp furnace fan 3.
Now let me start with the most important question.
To find the watts you multiply amps times volts.
Here s what to know and what to do there s no need for a super max turbocharged fuel injected 500 horsepower big block generator to get the job done.
You need to know it s approximate starting wattage and the wattage required to run.
These include things like a well pump refrigerator and freezer and lighting circuits.
Running wattage aka rated wattage is the power you need to run the appliance continuously after the initial startup.
To run this refrigerator you will need an inverter that can handle 600 watts for long periods and a surge of 1 800 watts for a split second.
The generator that can deliver at least 2000 starting watts will be sufficient to run both the refrigerator and the freezer without.
What size of a generator do you need to run a fridge.
The size of the generator you need depends on your power requirements.
Amps x volts watts.
Highest additional starting watts 1550 running watts 2950 total 4500 starting watts tool or appliance running rated watts additional starting surge watts 1.
On average depending on their size home refrigerators need around 1000 2000 starting watts.
You do not need to run a generator full time to keep your freezer or fridge cold during a power outage.
With this total example you need a generator that produces at least 2950 total running watts and 4500 total starting watts.
The equation above.
You can run the most critical household equipment with a generator rated at 5 000 to 7 500 watts.
To select the correct size generator you decide if both refrigerator and freezer are to start at the same time.
The first thing you need to figure out the wattage rating of your refrigerator.
You can do this by finding the amps and the volts on the electrical label on the device.
For instance if your generator is rated at 1 500 watts it should handle the example refrigerator s 1 050 watt starting demand with ease and run the unit without problems.
This generator sizing sheet will help you to determine your running and starting watts so you can choose the correct generator for your needs.
If you choose at least a 2000 starting watts inverter unit yamaha ef2000isv2 wen 56200i or generac gp2200i you should be able to power any medium sized modern refrigerator safely.
Size of generator to run a chest freezer or refrigerator.
If so you would need 1 800 x 4 7 200 watts.
