During power outage is not the time to discover your facilities power needs. That’s why we've developed this Calculators to help you consider your needs and to help you think about what you would like to power during a power outage at your home or business.
The calculators provided below are to help you determine the generator size that would best suit your needs based on what type of business you are running. Please be advised that there are a multitude of factors to take into consideration when generating a generator size as well as the complexity of electrical calculations. The assistance of a certified electrician is recommended. If you have any questions about computing power or would like further assistance, please feel free to contact us at your convenience.
How to size a generator?
Sizing a generator may seem to be a straightforward task: calculate the total power output of the equipment that you need to run, take into account the starting wattage (as it can be several times higher than the running wattage), convert this data to kW, and ensure that the generator can give you sufficient power, which is just above your maximum required power.
There are various generator sizing calculators available on the web, and simple conversions below can help you too, if you are looking to roughly calculate what size generator you need.
Convert kVA / kWe / HP
In the Power Calculator, 0.8 Power factor is typically used. However, this figure does vary depending on the installation that will be powered. If a leading power factor is onsite, please contact us to assist you with sizing.
All online calculators only provide a very rough estimate!
All online generator size calculators only provide a very rough estimate, which we recommend being taken as guidance only. If you are looking for power that is energy efficient, can save you fuel and reduce emissions as well as costs whilst reducing the chance of equipment breakdowns, let our specialists guide you.
Generator sizing done the ELECTRONIL Way
At ELECTRONIL, we treat generator sizing as a complex task, and consider a broad range of factors, especially if you need to size industrial generators and are looking for an efficient solution. As a result, we may recommend multiple generators instead of one and some other options.
Below is a brief overview of factors influencing generator sizing:
Ambient temperature and altitude.
Minimum generator load / capacity.
Application (standby, prime power, or in parallel; operation hours, etc.).
