Victron Multiplus II Wiring Tutorial

In this video Ben shows you how to wire the Victron Multi-plus II AC input connections.
Here is some more information about the Victron Multi-plus II:
The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid. It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A). It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals
The MultiPlus-II is the key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters.
The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.
In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.
When coupled with a GX device (e.g. Cerbo GX) you can monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world,, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto starting a backup generator and more…

Great video! Good job Ben!!!

[@NAZSolarElectric]

Thank you!

[@andrejsmith]

I appreciate your presentation style. With my having a background in electronics and a desire to 'do stuff myself', you give a trust-inspiring mix of solid technical info and layman tips that tell me 'I can do this and do a great job!'

[@NAZSolarElectric]

Thank you! That is a big reason why we produce these videos! Let us know if we can help!

stirdy cables 6AWG gauge 16mm2 must be 10000 watt on 230V grid?

[@awesomedee5421]

Can you hook up only L1/N/PE, and supply 120Vac into the inverter, and get 120Vac out. It looks like the unit is made for 240Vac, but wondering if it accepts L2=0V. and still works

[@NAZSolarElectric]

Yes but it would make more sense to use this product instead, which is also less expensive: www.solar-electric.com/victron-energy-multiplus-ii-inverter-charger-12-3000-120-50-120v.html

[@awesomedee5421]

@@NAZSolarElectric I was looking for starting 120Vac, and later supporting 240. so instead of getting two separate 120Vac units (which would ultimately cost more), it would be cheaper to get one 2x120Vac units. 48Vdc when it comes out for the US market.

[@tylerphillips5689]

Did you just not plug anything into the L2? And has it worked for you? Did you also do the same for the output? Thanks

[@awesomedee5421]

@@tylerphillips5689I think the problem is that with the 240V version, you don't get a neutral that is used in the US Split Phase system. The other L2 is the neutral return from what I heard, so you onlyhave L1, L2, and PE. To do what you want, I would think You need L1, N, L2, and PE. then you would be able to ignore L2. You have to use an autotransformer to get your neutral split phase, or buy 2x 120V versions. I think the later is better since you could have unbalanced loads with split phase and it could deal with that.

[@scrogathon]

If i had a breaker setup for 240v and then ran the inverter at 120v what happens to the appliances that require 240 that are only recieving power on one leg(120v)

[@NAZSolarElectric]

Thanks for your question!
The 240V appliances wouldn't have power. If you're not feeding in power on both legs (with phases 180° out) then there's no electric potential between the two legs and thus the appliance wouldn't function. There would only be electric potential between hot legs and neutral/ground, that being 120 Volts. However, a lot of 240V appliances; like dryers and ovens often carry a neutral for the control circuitry (which runs on 120VAC). In this case, voltage potential between neutral and hot would be 120V and thus the control system would have power to function but the 240V system would not, so the appliance would likely error out or not function correctly.

[@scrogathon]

@@NAZSolarElectric thanks alot for the explanation, it really helped clear things up for me. Going to purchase the multiplus ii with 2x120v.

[@NAZSolarElectric]

@@scrogathon that's great! Glad we could help!

NEVER use ferules on spring loaded terminals! NEVER! The spring has not the power to “compress” the ferule like a screw terminal and leaves you with a very tiny point of contact…

[@NAZSolarElectric]

Thanks for watching!

[@13FPV]

@@NAZSolarElectric Be smarter than Victron... Although it's recommended by Victron to use ferrules, it's not like it should!

[@MultiliminalDotCom]

If not using ferrules, then what do you suggest? Inserting the stripped wires as they are? Or soldering them first and then inserting them?

[@13FPV]

@@MultiliminalDotCom Just strip the wires and insert them as they are. If you solder them, then it's the same as using a ferule, it doesn't compress. The spring loaded terminals are especially designed as a good conductor for stripped wires.

[@740GLE]

@@13FPVhave you tried pushing in fine strands like that, it’s like trying to poke your eye out with a cooked noodle.
Maybe THNN is better without ferrules, but fine strands of SOOW a ferrule is almost vitals to doing it right.
