While there is no substitute for having a certified electrician perform an inspection and calculate everything for you, the guidelines below do offer some great starting points and should at least get you started in the right direction:

Know Your Requirements: Going to a dealer and buying the best or cheapest generator available without any other consideration is clearly not the best approach. It is always better to delve deep into your power generation requirements before making a choice. You can do this in the following ways:

- Make a list of the items that need to be powered by the generator
- Make a note of the starting and running wattage of the respective items
- Calculate the total power requirements in KVA or KW
How to Find the Starting and Running Wattage: Getting the right starting and running wattage of the devices you intend to power is crucial for calculating the accurate power requirements. Normally, you will find these in the identification plate or the owner' ...more

The choice between portable or stationary comes down to what you need the generator for. If it is merely to run essential appliances---refrigerator, furnace, stove and lights---for a short amount of time, then a portable generator may be the best bet. These generators have outputs ranging from 1,000 watts (the Yamaha EF1000ISC) up to 17,500 watts (the Generac Guardian Ultra Source).

Stationary generators are usually hooked into natural gas or oil lines and wired directly into the electrical system of your home. These behemoths output well into several thousand kilowatts of power for almost infinite amounts of time. The Carrier brand 35-45kW Air-Cooled Home Standby Generator, for example, outputs a running wattage of 26kW to power a 5,000-square-foot home. Generators this size are best used for either long periods of time or for large power needs.

I KVA means 0.8 Kilo Watt. So you have to see what is the wattage you use in ur home and buy a generator of equivalent capacity.
