The runtime of a 3000-watt inverter on a 12-volt battery depends on the capacity of the battery, measured in amp-hours (Ah). To calculate, first convert watts to amps using the formula: Amps = Watts / Volts. For a 3000-watt inverter at 12 volts, it draws 250 amps. If you have a 100 Ah battery, for example, it would run for about 0.4 hours (24 minutes) under ideal conditions, not accounting for efficiency losses or the battery's discharge limits.

They are not compatible. You cannot connect any AC device to a DC battery without a inverter. The size of the inverter determines what it will run. And the wattage of the fan determines what size inverter to buy.
When using the Inverter the CCU can be adapted to the users needs. A regular 12 volt battery would work on any small devices.
An inverter converts direct current into alternating current. An inexpensive 12 volt inverter is often used to convert 12 volt direct current from a battery to 120 volt alternating current to power small household appliances during a power failure. More expensive inverter systems with large batteries are also available for use with solar panels, wind generators, or other non-commercial power sources.
ConverterA converter changes AC house current (120 volt in North America) into 12 volt DC battery power. Current production of Converters are also smart battery chargers to keep your battery up while not over charging it. InverterAn inverter takes 12 volt DC battery power and converts this electricity into 120 volt ac power.
That would probably depend what you mean with "use with"; for example, connecting two such similar objects, but with different voltages, in parallel doesn't seem safe to me.

No, the capacity of the battery is too low to be of any use.
You "could" run a 120V 5A window AC unit off a 12V deep cell battery but, assuming 100% efficiency (something you can never get), you would need an inverter or motor-generator set and 50A out of the battery to run, and maybe 5 or 10 times that to start.
The amp hours capacity of a battery remains the same whether it is connected to a 12-volt DC load or a 120-volt AC inverter. So, the battery would still have 100 amp hours regardless of the inverter voltage.
It is generally not recommended to run a 12 volt inverter with 18 volts input, as it can damage the inverter and connected devices. The input voltage of the inverter should match the rated voltage to ensure safe and efficient operation.
To determine how long a 1000VA inverter can provide backup power, first calculate the total wattage of the devices: if each fan is around 50W, lights are 10W each, and the TV is 100W, then the total load is approximately 600W. A 1000VA inverter can handle this load, but the runtime depends on the battery capacity. For example, a 12V battery with 100Ah capacity can provide about 1200Wh, which would last roughly 2 hours at a 600W load, factoring in inverter efficiency and battery discharge limits.
