Multiplus II - 48v/3000/35/120 - How to wire for 50amps in?

My Multiplus ii unit does not have 4 AC-in connection ports, only has N, PE, L.

My understanding is that 50amp power has two hot legs L1 and L2. The manual even states that there should be 4 connection units in the 'AC-in' area.

How can this unit still get 50amps of AC-input?

What am I missing? Purchased the unit in Canada from a local supplier.tempimagecknrtd.gifscreenshot-2023-01-24-at-55521-pm.png

Are you confusing your multi with the MultiPlus-II 2 x120V split phase inverter charger?

No jus trying to understand how to get 50amps of AC power into my unit without two legs.


Does the one hot (L) wire provide the full 50 amps?

The number of phases is not what determines this, unless you are using a special split-phase model these units are ALL single phase. 50A transfer is not problem given the correct wire size. Subsequently even much larger units have "only" single-phase input. Depending on your country and feed-in even more amps are possible per phase.
