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).

    Also is there a single on/off switch that controls all 30 kW of lighting at once?

    Indeed - simple sequential start arrangements (anything from a lot of carefully co-ordinated on-delay timers to just a bank of separate lightswitches) can side-step a lot of inrush problems.

    This will be the final solution.

    I was just trying to understand if the generator could be damaged from high currents of short duration.
