Multiplus 3000 - ratings

Questions regarding Multiplus3000:

  • Is there a 48vdc version suitable for 110V ac? I have no use for the dual ac input of the quattro.
  • Can I set the input current limit low enough for a 600W generator? (It’s 1200W, but I live at high altitude and use propane).

    Thanks!

1. No, there is no 48Vdc 3000VA 120Vac MultiPlus available, so you will need to use the Quattro.

2. The lowest input current limit for the 48Vdc 3000VA Quattro is 7.4A -> 888W.

Thanks for this response. I'll get a smaller 24V MultiPlus. The information I found in the datasheets about minimum current limit is a bit incomplete (I may not have looked in the correct place).

For the 24/2000: Remark: lowest allowable current setting for PowerAssist: 8,5A*. (8,5A per unit in case of parallel operation) * Applies only when PowerAssist is enabled. No information about the limit without PowerAssist.

The Multi Control manual seems to contradict this: "When PowerAssist is enabled there is a minimum AC input current limit of approximately 2-3Amp per device. Setting a lower limit than this minimum will result in the minimum limit. This is normal Multi/Quattro behavior." If that applies all may be fine.
