Normally, power inverters work for a long period of time - but it also depends on what appliance or gadget was it used for. For small in-vehicle type of inverters, it can run an equipment for a long period of time, and as long as the car engine is running and battery power is good.
Yes you can use a UPS provided it can supply enough power for the server and you have good battery backup. A inverter is an option but a little bit more complicated, you will need a good battery charger and you have to run the server on the inverter alone, so the inverter will work 24/24 because you can not use mains supply to the server, so it have to be a good quality inverter, preferably a sine wave inverter with a 100% duty cycle, good batteries and a good charger that will supply enough charge to maintain the current draw of the inverter and have reserve to store energy in the batteries for times when the mains is out and the charger can not supply the energy demand.
The most usual type of electrical power inverter is an electronic device which converts a direct current supply - often at a low voltage such as 12 or 24 volts as is used in a vehicle - to a higher voltage alternating current such as 120 or 240 volts which can be used to supply power to a household electrical appliance. Inverters do what the name implies: they invert one type of power source to another type such as from DC (direct current) to AC (alternating current). In addition inverters can be used to convert a power source to a different level [VOLTAGE]. No matter what type is involved, because no inverter'e efficiency can ever be near to 100%, there will always be some loss of energy from the power that is supplied to the input to the power that is available at the output, but that is a small price to pay for the convenience of using an inverter.
A 1-ton AC can melt a ton of ice in 24 hours. The power needed is theoretically 3517 Watts so allowing for power factor and efficiency you would need a 7 kVA generator.
P=VI, so P=24*2 = 48W.
They were able to operate the entire day (24 hours).

You need 3000 x 24 watt-hours or 72,000 watt-hours. A typical car battery has a capacity of 50 Ah or 600 watt-hours, so you would need 120 car batteries, connected in the right combination of series and parallel to give the right voltage for the inverter.
Power inverter systems are essential tools for long car road trips. These systems convert a vehicle's battery power into standard power that is compatible with common electronic devices. An inverter system makes standard 110-120 Volt power available anywhere on the road. With multiple receptacles, you can plug in several electric powered devices right into your inverter system. Inverter system are available in different peak power ratings, which are designed to handle only a certain amount of electric load. If you plug in too powerful devices, then your inverter may burn, so it is important to have a safety feature such as fuses and surge protection. Standard power ratings on inverter systems are several thousands watts. The most common Voltage ratings in car inverters are 12 V or 24 V in Direct Current.
No more than 24 hours.
I work 24 hours a day.
You would need to use a power inverter to convert the 24 volts DC from the battery to 110 volts AC. The inverter steps up the voltage to match the standard household voltage. Make sure to choose an inverter that can handle the power requirements of the devices you want to run.
i have to work 24 hours
Use an inverter. Most inverters are sold to provide 120/240 volts from a 12 or 24 v power source.
about 24 hours a day ...
Cashiers can and do work 24 hours a day, seven days a week. Lots of stores are open 24 hours a day now.
Termites work 24 hours (around the clock)
