Must be a small freezer... most I have seen take a lot more than that to run due to the strartup surge requirements of the motor.

You wrote 3kv, which means 3000 volts.I doubt that is correct.

What size generator in watts, kilowatts, or VA or kilovolt-amps?

Voltage?

What size refrigerator in watts or amps?

Good point... I had assumed they meant a 3KW portable generator... as that's a common size. Since English is not their first language.

Freezer load is two ampers
And generator is 3000 watts.
Please tell me what I should do.
Reply me as soon as possible.

Get a bigger generator Like 5,000 watt or bigger. The 2 amp is running current... the start up current every time the motor has to start is far higher and tripping the breaker. And since the compressor will cycle on an off often... you have to plan for the MAXIMUM load... which is startup.
