A thousand watts is equivalent to one kilowatt hour of electricity and 3,000 W is equivalent to 3 kilowatt hours of electricity. But the number of kilowatt hours of electricity produced by the generator depends on the load. 3 kilowatt hours are when fully charged.
or
Power consumption is equal to electric power times time W=PT, the unit is kilowatt hour (we usually call it degree) 3×1= 3 (kilowatt-hour) 3,000-watt electrical appliance Electricity consumption per hour is 3 kilowatt-hours, or 3 kilowatt-hours of electricity.
Detailed information:
Normal lighting uses current, I is equal to P0 divided by I=P0/U0.
The power changes as the voltage changes, but the resistance remains unchanged.
To find the resistance of an electrical device, R is equal to U^2 divided by P, R=U^2/P.

Not that expensive.
I am a Mindong engine manufacturer. Although we don't sell any, it's not expensive
Petrol fuel consumption is 1.2 liters per hour
Probably not. At 2,000,
Solar energy will definitely not be able to meet your conditions at this time.
