Great video! You do not need to release the latch when inserting. 👍

[@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!

[@UKsystems]

Hot weather, this is not a DIY thing at the bare minimum mutual consult the dealer many things if not done can end up dangerous

[@tmarbut]

Thank you for a great and helpful video! Just the info I needed. However, PLEASE nobody strip wires like poor ol' Ben here. Stripping like this (1:49) is a recipe for damaged insulation and arcing under the right circumstances. I've definitely seen it in the wild! If it's not obvious what I'm talking about Support the cable and knife together in one hand while rotating the cable with the other to control the depth of the score on the insulation. Be willing to make 2-3 complete passes around. Only go 60-80% of the way through the outer jacket, and then bend it around until something opens up. (Make another pass if nothing does.) Then add a little tiny bit of score here and there as you bend it and it comes loose. Then, even though it's very convenient (2:08), you should avoid slicing up the outer insulation like this. Usually you can wiggle the outer insulation off with 5 more seconds of patience. If you're working in a difficult place and absolutely have to do more to relieve the jacket, either try to slip the knife blade underneath so you're cutting away from the wires, or follow the paper up the sheath so where your blade pokes through, it isn't scoring the wire insulation underneath. In all cases, keep the underlying wire insulation intact!

Great video! Good job Ben!!!

Thank you!

Great video BTW, keep'em coming

thanks, very helpfull

Glad it helped!

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!

[@smfdmo]

Great video! Easy to follow and very informational. I found the spring system to be a horrible experience! very hard to connect and the wires continued to slip out. It's hard enough in such a small area with larger wires. Please go back to the screw down method!!!

[@NiklasWeisheit-uy3ih]

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

[@Thermal694]

Why does my multiplus ii not chage off 240v. It clicks then stops.

[@UKsystems]

Victron have explicitly stated only fine stranded wire shall be used in any connection would a ferrule not mechanically create a solid strand? Also, only Americans needed tutorial on how to use a terminal.

[@hiwait]

9 minute video you connected one single cable and you call it a wiring tutorial?

[@13FPV]

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.
