Yes, because the maximum power of the refrigerator compressor is 140W and a 700W motor can operate it.
But here's an idea. The rated starting voltage of the compressor is 220 V, and the lowest starting voltage is 198 V. This means that the generator output voltage should always be higher than this value. the refrigerator will stop.
In addition, operating the motor in a low voltage state for a long time will increase the load on the coil and shorten the life of the motor. It is always recommended to use a standard 220V power supply to power the ice and snow.
My friend, you did not say how many liters the freezer and refrigerator cost, I can only give you general data. The power of the freezer is generally more than 200 watts, and the power of the refrigerator. is generally greater than 100 watts. The total power isaround 700 watts and the starting current is relatively large, so it is better to choose a generator around 1000 watts.
