Victron Multiplus II 12V - Model Comparisons

Logan explores the differences and updates in the new Victron Multi-plus II models, specifically the 12V options.

The MultiPlus-II 2 x120V is the perfect one-box mobile solution for standard North American 50A 120/240VAC split-phase applications. Whether it is supplied from shore power or a generator, the MultiPlus-II 2x120V can accept and passthrough both lines of a 120/240V supply, with the capability to utilize the full 50A for charging and AC loads. When connecting to a single phase 120V supply, the L1 input of the MultiPlus-II 2x120V will accept incoming power for charging and passthrough, while combining the L1 and L2 outputs for single-phase 120V on each line.

The MultiPlus switches to inverter operation when no AC source is available. The inverter output is also 120V single phase. In inverter mode, the MultiPlus-II 2x120V internally connects both lines L1 and L2 together to provide 120VAC to loads on either output. Therefore, in all connection circumstances, both sides of a distribution panel will be supplied with 120V. However, 240VAC is only available when the MultiPlus is supplied by a split phase 120/240VAC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery.

The MultiPlus-II 2x 120V has all of the expected features of our versatile inverter/charger range, including PowerControl, PowerAssist, Input Current Limit, two AC outputs, as well as parallel and 3ph configuration for larger capacity VE.Bus systems. Suitable for LiFePO4 batteries and a variety of other battery technologies.

I bought a 12V MultiPlus II from Logan as part of a system. Logan and all of his co-workers are polite, professional, and helpful.

I love my victron 150-70 charge controller and im buying another 150-70 for another 1850 watt array very soon. Victron is expensive but seems to just work

Excellent video, what is not clear to me is the benefits of the original Multiplus over the new Multiplus II. In what use case would the original be the right choice? Usually when a new model of something comes out the old one is no longer produced but I still see lots of installers using the old version. I can see that for replacement you might want to get an old one but for a new install I can not see why you would not always go with the Multiplus II or IIx2

[nwlady]

so the only difference between multiplus and multiplus II is size, about 2 lbs and multiplus II has a current sensor?

[calculatedrisk]

I assume the multi plus 2 2x120 is a 3k watt total unit. Not 3k watt per leg?

[carlosreyes]

Is power assist available on, all muti plus ii, inverters? Meaning 12v 24v and 48v.

[SublimeTree]

Thanks for the info. I'm configuring a system and I like the sounds of the multiplus 2 2x120v. But I don't no if it's best for a 24v system on a rv with a 30 amp system currently. Any thoughts would appreciated.

[earlzeis]

More information on the add on current clamp please.

[MrMinnesota]

Is the charger power factor corrected? What is the power factor while charging?

[Noah-qtrq]

I would also mention that the multiplus 2 has a lower idle consumption.

[ronbridegroom]

I find the Victron series of inverter/chargers to be very confusing and not really suited for the North American home market due to an apparent lack of support for split-phase 240v

[sundancer]

The original model looks like it would cool better. Any thoughts on this, anyone ? Cheers, Simon.

The bad thing about the newer multiplus II style is they are loud especially under full load. Quatro all the way. They are way quieter.
