What voltage?
The load is a little over 2kW, so the output needs to be rated no less than 2.5kW continuous (assuming the load is continuous).
--------------------------------------------------------------------------
The voltage is regulated by the number of field windings versus stator windings, multiplied by the voltage added to the field from a DC source. Phase factors and operating power factors will also affect the total kiloVolt-Ampere output of a generator. this is often factored in for household emergency generators and a generalized rating is given for a 220 volt output. for a 2049 watt load at 220 volts a single phase generator with with an output of 2500 watts or more should be used. The phase factor would be 1:1, power factor negligible (unless hooked to the power grid), and motor(generator) efficiency is about 96% typically. Adjusting for a 25% peak load (when items turn on and off) then:
(2049w/0.96)x1.25 = 2668 watts , a 2500 watt generator will handle it if not all things attached to it start at the same time.
This is equivalent to a 100amp circuit load at 220 volts or 200amps at 110 volts. (circuit breakers), most houses require a 200 or 300 amp service (add up all the circuit breakers in use in the box.)
note: single breakers are typically 110 volt and double breakers are typically 220 volts, when adding up breaker's amperage double the load for double breakers to compare the loading at 110 volts.
example:
Circuit box has 2 double (220v) breakers, stove/oven 30 amp, water heater 45amp, and 12 15 amp single breakers (110v) the total load for the service is:
(30 x 2)+(45 x 2) + (12 x 15) = 330 amps (@110 v) or 165 amp service (@220v)
165 amps x 220 volts = 33000 volt-amperes , because emergency generators are rated at 220 volts the kilowatt output needed is 1.65 x 125% = 206.25 kw @ 220 volts
For industrial generator ratings: volt-amperes = kilowatts x power factor x phase factor (3 phase generation phase factor is 1.732, power factor is adjusted by adjusting the field voltage) , these do not apply with emergency generators. {volts x amperes = watts}
Assuming a power factor of 1, a generator with a minimum capacity of 2.5 kW (approx. 2500 watts) would be suitable to power 2049 watts of load, providing some buffer for efficiency and surge requirements. It's generally recommended to round up when selecting a generator to ensure it can handle the load comfortably.

What size breaker is needed to connect 5500 watt gas powered generator?
A 5500 watt gas powered generator typically requires a 30 amp breaker for a 240 volt connection. It is recommended to consult the manufacturer's specifications to ensure the correct breaker size for your specific generator model.
What cable is needed to go from a generator to the electrical supply?
A transfer switch and appropriate power cord are needed to connect a generator to the electrical supply safely. The transfer switch ensures power is only supplied to the desired circuits, and the power cord should be the correct type and gauge to handle the generator's electrical output. It is essential to ensure proper installation and follow safety guidelines when connecting a generator to the electrical supply.
How many kW generator for a home?
The size of the generator needed for a home depends on the power requirements of the house. A typical range is 5-20 kW for a residential property; larger homes with more appliances and systems will require a higher kW rating. It is recommended to consult with a professional to determine the specific size needed for your home.
Is a 2.8 kilowatt generator big enough to run a house as a standby?
It depends on the size and energy needs of your house. A 2.8kW generator may be able to power essential items like lights, refrigerator, and a few small appliances during a power outage, but may not be sufficient for larger homes with higher energy demands. It's best to consult an electrician to determine the appropriate size for your specific needs.
What size home standby generator do you need for a 4500 square foot house?
A 22-27 kW home standby generator would generally be suitable for a 4500 square foot house. However, factors like energy usage, appliances, and climate can impact the recommended size, so a professional assessment is recommended for accuracy.
What size diesel generator should I buy for a house this hurricane season?
The size of diesel generator varies greatly. The size that is needed would depend on the size of the house.
What generator size is needed for 0.5 hp 220 volt 1 phase?
The generator should be about ¾ hp.
What size generator is needed to operate a 4 ton York air conditioning unit?
To answer this question the voltage and amperage of the unit must be stated. Once this is given the generator size can be calculated.
What size diesel generator would you need if there was a power outage?
The size of the generator is based on the size of the load you want to supply. Size up the load in watts or amps along with what phase (single or three) and voltage that the load requires. These are needed to give a complete answer.
What size generator is needed for a three bedroom house?
A generator for a three bedroom house would be medium sized. Try a small to medium sized generator that can be found online or at any hardware store in your neighborhood.
I need a 120V 208V 3 phase What size of 3 phase transformer do you need?
The sizing of transformers is based on an accumulation of all of the loads that will be connected to it. Add up all of your loads and possible loads in the future and then tell your installer the figures and they will use these to calculate the size of the transformer that is needed.
If you have 1200 watt generator how much will voltage drop with 100ft extension cord?
To answer this question more information is needed. The wire size of the extention cord is needed.
What size breaker is needed to connect 5500 watt gas powered generator?
A 5500 watt gas powered generator typically requires a 30 amp breaker for a 240 volt connection. It is recommended to consult the manufacturer's specifications to ensure the correct breaker size for your specific generator model.
What size generator do you need to move a 30 hp electric motor?
A 5 kW generator would turn it over but if the full 30 hp of mechanical power is needed, that would require about 30 kW of electric power from the generator.
What cable is needed to go from a generator to the electrical supply?
A transfer switch and appropriate power cord are needed to connect a generator to the electrical supply safely. The transfer switch ensures power is only supplied to the desired circuits, and the power cord should be the correct type and gauge to handle the generator's electrical output. It is essential to ensure proper installation and follow safety guidelines when connecting a generator to the electrical supply.
