LED inrush current and generator set

Julien Leblanc
Hello,


I'm currently working on a sport field application where i need to power some LED reflectors (30 kW total).

I will also use a generator set, in case the network fails.


The inrush current of the reflectors is 3 times higher than their rated current, but the duration is only 0.2ms.


Could anybody tell me if i should take into account the inrush current when I choose the generator set power (that is, to oversize the generator)?

Or i should ignore the inrush current and set the power of the generator a bit higher than the total power of the reflectors?

I'm not talking about the circuit breakers of generator's outputs. Let's say one can choose them so that they don't trip.

If those breakers don't trip, is it possible that anything else happen to the generator set, because of the inrush current?


I've been searching through the specifications of many generator sets, but i cannot find any data on this specific problem (short overload).

    There will be an ATS installed, which will start the generator, then connect the load.

    Yes, one single switch.


    Thank you for the reply, is this an existing lighting installation to which you are adding the generator/ATS etc?


    And what is the budget for the generator, is it intended for safety purposes, such as lighting for a large crowd to be safe in the event of a mains failure or is it for revenue protection ie to prevent commercial events having to be abandoned due to lighting failure?




    It's a new installation.

    The generator is necessary for safety purposes and also for the continuation of the events, in the case of a mains power failure.
