To calculate the generator capacity, you need to know the total power needs of the equipment you will be connecting to the generator. Start by adding up the wattage of all the equipment that you plan to run from the generator. This total wattage is the required generator capacity.

For example, if you plan to power a refrigerator that has a wattage rating of 800 watts and a television that has a wattage rating of 200 watts, then you will need a generator with a capacity of 1,000 watts.

It is important to remember to add up the wattage of all the equipment that will be connected to the generator. You should also take into account any additional wattage needs such as the starting wattage of the equipment.

It is also important to make sure that the generator is capable of providing enough power to meet the needs of all the equipment that will be connected to it. If the generator is not powerful enough, then it will overload and cause damage to the equipment.
