The equation that you are looking for is I = W/E. Amps = Watts / Volts.
To calculate the amperage, use the formula: Amperes = Watts / Volts. For this situation, it would be 4000 watts / 115 volts ≈ 34.78 amps.
There is not enough information to answer your question directly... In order to determine how many volts it takes to make 4000 watts, you also need to know how many amperes there are. That is because watts is volts times amperes. For example, if you had a 120V system, you could divide 4000 watts by 120 volts to get 33 1/3 amperes.
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
To determine the amperage, you need to know the voltage of the air conditioning unit. If we assume a standard voltage of 120V, then 4000 watts is equivalent to approximately 33.3 amps (Watts = Volts x Amps). If the air conditioning unit operates at a different voltage, you would need to recalculate using that specific voltage.
There are a few components missing from your question. I need to know either the voltage or the amperage and the power factor. For single phase, the formula for Kilowatts is Amps x Volts x pf/1000. The formula for Kilovolt-Amperes is Amps x Volts/1000. As you can see more info is needed.

4000 BTU = 1722 watts
about 4800 watt but should not use it 100% so to be safe 4000 watt (80%)
Amps x volts equals watts...200 amps at 12 volts would be 2400 watts...add a few more because. the inverter efficiency is not 100 percent...

There are zero watts for 4000 amps. The formula for watts is; W = A x V, so you see a value for voltage has to be stated to give an answer.
To answer this question, you will have to add up the wattage's of the appliances that you think need to be run on emergency power. Keep in mind that an appliance with an electric motor will need more power to start the motor than what it operates at. Some amp ratings for fractional HP motors at 115 volts are 1/6 = 4.4 amps, 1/4 = 5.8 amps, 1/3 = 7.2 amps, 1/2 = 9.8 amps and 3/4 = 13.8. If the motors are 230 volts divide each amperage in half. To convert these motor amperage's into watts use the following formula. Watts = Amps x Volts. Starting an appliance with a motor on this size of generator will definitely drag the voltage down momentarily. The closer that you get to the generators capacity, the more the generator struggles to keep the voltage up. When the generator gets to this amount of overloading usually the generator breaker will trip. With too much load you can actually stall the generator and it will stop turning.
5000 (watts) /120 (volts) = 41.6 amps , but to be safe you should allow 1000 watts margin for peaks, so 4000/120 is 33.3amps, although peaks might sometimes get higher than 5kw
