Can a Multiplus II 50A be used in a 30A RV?

Hello. I recently bought a Victron Multiplus II 50A, with PE, N, L1 and L2 connectors on the AC lines. However, my RV has a 30A system, with PE, N and L. Can I use the Multiplus II with such a system and wire only the L1 circuit?

Thank you.

Personally, I would return that unit and get a regular Multiplus 12/3000 120V:

If it doesn't make sense to return it, you should be able to completely ignore L2 and wire L1 to L and N to N, and it will work fine.

Thanks for the quick reply.

I would have to send it back across Canada, and, after shipping costs, I would end up with a Multiplus for the price of Multiplus II. So I’m going to keep this one and use L1, as you said.

We’re upgrading to a 50 amp coach next year and currently have a 30 amp coach and was wanting to do the exact same thing

I would not return it.

And yes it can use used in your system with just L1 and N.

You can just limit the current to 30A in VE.Config.
