how to properly wire Multiplus 2 48v 3000va in 2* 120v

I bought 48V due to my source limits and I am trying to wire this in RV in 2*120 configuration. Please refer to included wiring diagram. I am not sure what to do with input L2. Should be tight to L AC OUT 2?

Hello,

Please confirm if the inverter looks like this? The picture below is for the MultiPlus-II 2x120V Inverter/Charger version.

It would appear that the model being asked about is a normal single MultiPlus II and not the model in the picture above. The normal MultiPlus II can supply 120Vac on both the ACout1 and ACout2 outputs, but it is a single phase output. RV PowerIn L2 AC cannot be connected.


Hope this helps.

That is very pitiful, since I bought it under assumption it is 2*120V split for RV. I guess it is luck of explanation that 48V is different from 12 and 24 V versions. And your documentation and support honestly sucks.

Hi, very few of us work for Victron; most just like Victron and try to help on the forum with what we know. I did not create the documentation.

It is possible to your load on L2 to the ACout2 when the grid is disconnected using a contactor. But this will be a single-phase setup.
