What size generator do I need for live music? Are you planning a live music event. This essential information will help you plan the correct power supply.
What Power Supply Do I Need For Live Music?
It can be challenging to assess how big of a generator you'll need for various jobs and tasks; you'll need to do plenty of research to make a well-informed decision.
DJs need an ample and uninterruptible power supply to get through a set or multiple shows a week or month. Professionals recommend running a generator with a pure sine wave output of surge watts and ensuring you put any power-hungry lighting systems on separate generators; these can be oil or gas-powered or run entirely on electricity.
We highly encourage you to invest in a surge protector, especially useful for expensive devices such as your DJ equipment; it will be a fantastic benefit that will help divert the extra electricity.
The most significant draw for any of your audio equipment will be your amplifiers; these will require as much power source as possible as they are the most vital aspect of DJ equipment, as your crowd need to hear you at all times. Like your decks and mixers, other tools that you can plug in may not draw out as much energy compared to your amplifying speakers, etc.
You must bear in mind that audio amps tend not to be 100% efficient, as plenty of energy is lost in the heat, which is why it's better to invest in a solid, high-quality amplifier, as much older models are often only 30% efficient.
The spec of your amplifier will inform its overall power consumption; if you find that it's written in volts and amperes, we encourage that you multiply these numbers together to achieve its running wattage. Once you have done so, you can begin researching power generators with the same power watt consumption.
How to calculate kVA
Generator power is typically measured in units called Kilo-Volt-Ampere (kVA for short or in equations). To find the size of your desired generator, you'll want to begin by finding out the total watts of power consumption.
Such includes all of the equipment you will be running during your live outdoor event; your decks, mixers, laptops, special effects devices, lights, amplifiers, etc. Significant touring artists and good companies tend to use around 80,000 to 400,000 rated wattage.
You'll have to convert these from KW (kilowatts) into kVA by multiplying kilowatts by the reciprocal of its power factor.
We refer to the power factor as the power flow ratio to its load and apparent power output. Older loudspeakers and amplifier technology would usually have a power factor of around 0.3; however, some equipment has maximum power factors of around 0.8.
Here is a short example of the calculation you'll have to do to determine the kVA (kilo-voltage and ampere). Let's suppose we added up the total power consumption of all pieces of equipment within your sound system, which amounted to 5kw with a power factor of 0.8.
You'll start by doing one Ã· the power factor and then multiply that by the starting watts: 1 Ã· 0.8 = 1.25 1.25 x 5 = 6.25 kVA
