To determine how much kVA (kilovolt-ampere) generator you need, you must consider the total power of the devices you want to connect. Here are some steps you can follow to estimate the required kVA:
Make a list of all the devices you want to connect to the generator. Note the power (expressed in watt or kilowatt) of each device. The power is usually stated on a nameplate or in the device's manual.
Determine which devices will be used simultaneously. For example, if you want to use a refrigerator and a TV at the same time, you need to add up the combined power of both devices.
Add up the power of all devices used simultaneously to obtain the total power. Make sure you express the power in kilowatt (kW).
Add a safety margin to the total power. It is advisable to apply a margin of 10-20% to ensure the generator provides sufficient power and does not become overloaded.
The total power obtained with the safety margin gives you an indication of the required kVA for the generator. Usually, the power of a generator is expressed in kVA, so you can use this directly when choosing a suitable generator.
For example, if the total power of your devices is 5 kW and you want to apply a safety margin of 10%, you would need a generator of approximately 5.5 kVA.
It is important to note that this is an estimate, and specific power requirements and applications may vary. If in doubt, it is advisable to contact a professional supplier or an electrician to help you determine the correct generator size for your specific needs.
