Basic Portable Generators
Portable generators are produced in sizes ranging from a few hundred watts to 15,000 watts (15kW).
Basic Standby Generators
A standby generator is a permanently installed generator that is attached to your electrical service panel. Most of the standby generators start automatically and are connected to a large fuel source such as propane or diesel fuel.
Even if you were to purchase a 10,000 to 15,000 watt portable generator you would find it more expensive, difficult to move, noisy, and the fuel consumption will be large.
Typically you will not be able to run you home's central air conditioning system or electric heat pump even with a 15,000 watt portable generator.
