Victron MultiPlus Rating

We have a Victron MultiPlus 12/3000 rated at 2,400W or 3,000VA.

Which of these limits takes priority? For instance, if I'm running purely resistive loads with a power factor of 1.0 at a voltage of 120V, can I use 20A or 25A?

Hi @Matt Knight

At a power factor of 1, which is a resistive load, the unit is rated for 2400W at 25 degrees C. Battery voltage stability will also be a factor (higher voltage needs less current, and good connections mean less ripple).

The 3000VA rating is for a non-linear load with a crest factor 3:1. There is more explanation about what this means (and how you can have both 2400W and 3000VA ratings) in the AC chapter of Wiring Unlimited.
