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).

    How often/long would the standby facility be required? If it's for something like a football club and only needed when there's a proper match on - perhaps a few hours once a week or once per fortnight - might there be any mileage in starting the generator and have it just ticking over during the match, so as to be almost instantly available, but shutdown for the other 98% of the time?

    Yes, the facility will be used quite rarely, once every few nights probably. 

    Running the genset in standby would be the easiest way to solve the problem.

    Thanks.
