Starting 500W halogen lamps from battery / inverter system.

  1. I've been asked to provide power to a security system which includes a
    couple of 500W lamps controlled by PIR sensors.

    The good news is that as they are switched independently, the chances of
    them coming on at the same time is pretty small, but given that their
    resistance when cold is only a few ohms, I guess the battery / inverter
    system will find their switch on surge a challenging load.

    Does anybody have any experience of the size of inverter that will
    reliably start a lamp like this while also running say a kW of other
    equipment ?

    Thanks, J/.
