NEW Victron 48V MultiPlus-II 5000VA 120V Inverter - Breakthrough Technology?

[@TK-123]

Now this is the gold standard for inverter reviews! Thank you..

[@CurrentConnected]

Wow, thanks!

[@GavinStoneDIY]

It’s empty inside. Reminds me of those old cars back in the 70’s. Massive hoods with a tiny motor propped in the center. Looks good so far.

[@wbbgjr]

Current Connected has the best customer service. Very few companies out there like them anymore.

[@mikefranks4528]

agreed. Definitely much better than Signature Solar where their main focus is marketing, but Current Connected has the best customer service in that they pre-program their inverters if needed and talk to you about your project before ordering your components.

[@AaronBockelie]

If it hasn't been mentioned before, the current sense connector, the volume inside the connection enclosure, and a few other features changes are influenced by UL 458 requirements. I hope to see a cert (for United States) for these inverters soon.

[@overlanding.adventures]

Wow, this looks like a fantastic new unit from Victron! Especially the low idle power consumption at 15W 👌

[@MrSummitville]

Wait until you connect it to the grid and put a load on it. The noise and hum is incredibly loud.

[@LivingFree4All]

Really? I thought most are saying it's quite. I am interested in it's noise or lack of noise?@@MrSummitville

[@pickles6871]

🥳🎉🎉 Yay Current Connected

[@mikefranks4528]

was waiting for someone to pull out the oscilloscope to check sine wave quality. Definitely much better than grid power. One of the reasons why I have my computer running off my inverter rather than straight from city power.

[@cecilcoker7203]

Thanks so much for this well explained video on the output quality of the Multi Plus 2. I for one do love the on/off remote control connection. I can't wait to hook it up with some smart switches.

[@jstaffordii]

Wow 30 watts idle for a 240 split phase setup is awesome. Would like to see some peak output/ surge limit testing.

[@CurrentConnected]

Coming soon!

[@BOGGarage]

@@CurrentConnected I second this, I wonder how it compares with my 4x 48/3000s of course this comes out after I set all that up but output is 9.6kw vs 8kw

I would love to see an in depth breakdown of the Quattro 10k and a view of the sinewave on the oscilloscope compared to the Multiplus you did in this video.

[@CurrentConnected]

Great suggestion! We plan to work our way through the various models on our store in due time. We plan to have at least one video for each SKU. It may mean a couple slightly less interesting videos in the meantime and we apologize for that.

[@Rangband1]

Seconded as I am thinking of dual 10k Quattros

[@boomermatic6035]

If I lived in the Vegas area I would totally be applying every day for a job there, you guys have all the cool toys. :)

[@laurentsosson1739]

Hello and congratulations for the video I come to you for the multiplus can we use the ACin input not permanently on the network but just connect it to a 230V 20A socket (France) to just supply the ACin input to charge a park battery at night rate and use the ACout during the day to restore the energy to my electrical panel? because connecting the ACin to the network bothers me a little because it requires a lot of steps because if there is a risk of injection into the network it is necessary to go through a Consuel I would especially like to be in self-consumption and from time to time be able to close the multiplus with a source inverter in my prolonged absence and switch to the direct network laurent

[@patricklyons7683]

Got this in Quattro II 48/5000/70 240v UK. Oh this is a new revision!!

[@cgutowski471]

At the end of the video you mentioned an external transfer switch. Can you elaborate on that?

[@evillink81]

Really awesome product, are you aware of any possibility of having a 5K 2x120V version?

[@Data0verL0ad]

Wondering the same thing.

[@buddyt4447]

Which ac port would you recommend for grid tie using current transformer to prevent backfired with ess

[@2Langdon]

Hi, great analysis, very helpful, thank you. I want to set up a system using this inverter charger with the Smartsolar MPPT 450/100, do I need cerbo GX communications set up with it or can bluetooth do everything the cerbo GX can do? Thanks for any help.

[@dalehollenbaugh6084]

What is the minimum input current limit that this can be set to? It isn't listed in Victron's spreadsheet. Closest is Quattro 48/5000/70-100/100 120V and that has 13.4A minimum input current. Wondering if this is same or hopefully lower.

[@mikefranks4528]

Will Prowse tested only 20A running the multi II 3000va in parallel. Do you know the maximum amps this will produce, if 2 inverters are ran in parallel?

[@fc436]

A construction comparison with a hybrid like easun or another of the thousand clones would be interesting

[@oogie-boogie]

i just bought one of these,, and it wont work right out of the box,, i need a custom volt to run this,, my set up is 49.0 fully charged,, this thing just blinks at me saying my voltage is to low,,soooo i if i cant figure something out i just lost 2,000,it would cost a arm and a leg to send it back

This 5000 Multiplus Inverter srew terminals are also installed on the Multiplus 3000 48V 120V inverters??

[@MP-qn1jw]

Awesome!! Thanks for the video!!

[@gu4u2]

I have a Multiplus II 3000 W 120v. Could I pair this 5000W with it for a split phase?

[@CurrentConnected]

No, only matching inverters can be paired.

[@nielsdaemen]

And this can do on gird tie too right?

[@alexb.6800]

There're VE.Configure, Victron.Connect apps, CerboGX - what's the priority of settings for the system if they contradict there?

[@SH-pm1cs]

That s à good question ...

[@petersamios5409]

Not too technical - nicely explained.

[@dand9244]

have you considered reviewing the samlex evo 4024? or the new version that is split phase? curious how that stacks up with some of these metrics, victron is top tier obviously

[@CurrentConnected]

We plan to carry Samlex in the near future, so we will get some videos up on those as well.

[@GlennInLaguna]

I see your testing this with one 100ah Battery. I thought I read in the battery capacity specs of 200ah to 800ah, so I was thinking you needed to hook up two 100ah batteries for it to work? Would this inverter self adjust output with only one 100ah battery working?

[@GlennInLaguna]

Also, can you supply 220vac to this unit for charging your batteries?

[@AdamDeLayDIY]

Only word that comes to mind is WOW!

[@MrSummitville]

Wait until you hear the *loud* noise and hum when it is connected to the Grid and under load.

[@AdamDeLayDIY]

It's still not gonna be nearly as loud as the EG4 6500s were when they were under full load. I don't think there's any inverter that compares to that sound.

[@Paigeflowr]

Awesome video!

[@bnk28zfp]

if i purchase 2 of those -how much AC 250volt watt can you pull with this setup?? i have mitsubishi minisplit 8 unit in one i can suck emenergy like 8000-9000 watss when it starts then contunue working like 4500watts - will it meet my need????

[@CurrentConnected]

With two, easily. Each inverter can do 4000w (5kVA), so with two you could easily run over 8000W (more for surge capability).

[@herbertvonsauerkrautunterh2513]

I just bought a growatt 12kw inverter

[@maxmustermann9858]

What does low frequency mean in this context? Does it apply to the frequency of the AC out of 50/60 HZ but if so, wouldn’t be all inverters be low frequency?

[@CurrentConnected]

It refers to the topology of the boost circuit. In a high frequency inverter, very small ferrite transformers running around 100kHz generate the peak-peak voltage of the sine wave, before being rectified back to DC and chopped up to AC yet again. Since these inverters target a lower pricepoint, they skip the inductors that smooth the output. In a low frequency inverter, a single H-bridge circuit drives the transformer at a base frequency of 60hz and a sine wave is derived by modulating duty cycle of the H-bridge circuit. Since the final power stage of the low frequency inverter is the massive transformer, it means there is a lot of "momentum" stored in the magnetic field of the transformer and available for surge loads. The transformer also acts as a filter to keep any noise down on the output line.

[@maxmustermann9858]

@@CurrentConnected Thanks for the answer. May I ask where I can see if it is a high or low frequency Inverter in the technical specifications, do manufacturers normally tell or are there other things to look out for.

[@George_us]

​@maxmustermann9858 Sorry for jumping in. A low frequency inverter has a much bigger coil/inductor which results to the inverter to be heavier. So one can look at the weight of the inverter and say if it is low frequency or high frequency. The weight of a high frequency inverter is much less than a low frequency inverter because a high frequency inverter uses much higher switching frequency which requires smaller (lower weight) coil/inductor. I personally prefer a low frequency inverter because they can handle larger inductive (aka in-rush current) motor/pump loads.

[@maxmustermann9858]

@@George_us Thanks for the answer. I thought because low frequency inverters are obviously the better and more professional type there is some kind of marketing to clarify which type it is. But your answer definitely makes sense.

[@john0270]

​@majid_us yet my China inverter handles my fridge, ac and freezer startup and runs all of them at the same time.... pluss running a coffee maker and a hot plate. my 1200va victron inverter (at twice the price) struggles to handle anything individually.... next to useless

[@awesomedee5421]

Is this the same as the MultiPlus-II?

[@CurrentConnected]

Yes. "II" is the roman numeral for the number 2.

[@jimbob3030]

Victron could corner the market with these, I'm not aware of anything that can compete with the idle draw for this power output, but that victron price tag actually keeps sales numbers down. Are they actually costing themselves revenue by keeping prices high and volume of sales low?

[@HighTechLab]

I'm curious what inverter can do what this inverter can do for less money. What beats this in all other categories but the idle draw?

[@jimbob3030]

@@HighTechLab "What beats this in all other categories but the idle draw?" That depends on what you mean by beats it in all other categories. The victrons have more individual features on each part than the cheap chinese all in ones, but a lot of those features go unused and are just overkill for most people. You could buy 4 or more complete growatt all in ones for the price of just one victron full setup. (With victron you still need a MPPT charge controller on top of this, plus if you want it to all work together and be controlled by eithernet and bluetooth then you need all the other victron parts like cerbo gx, it's screen, the victron shunt and victron bus) And if you want split phase from this setup you'll need two of those $2k inverter charger boxes, plus all the other victron parts. All those costs of buying each part separate in the victron eco system add up fast and most of that basic functionality is included in the cheap chinese all in ones. If the cheap chinese stuff like growatt and eg4 and MPP solar were even close on idle consumption they'd have victron beat on value for the money hands down, but their idle draw makes them hard to deal with in places with a real winter where you might not be able to make up for the idle consumption by just adding more panels. If the light just isn't there more panels can't do much. If victron didn't have the super low idle draw, I wouldn't be drooling over wanting one. The only reason I really need a victron is for that low idle draw. If I had the money to burn I would ditch the two growatts I have now and replace them with the whole victron setup but that would be a lot of money, many times what I spent on the growatts.

@@jimhanty8149 Companies exist to serve maximum profit to their owners and shareholders, no reason other than that. Volume sales would serve more profit than trying to be an exclusive brand with limited sales.

It's a beautiful design but unfortunately don't expect Victron to honour their 5 year warranty if your inverter craps out. Mine just stopped working after a year and Victron totally ignored the request for repair or replacement. Considering that they are on the higher price scale compared to their competition you would expect better. Buyer Beware!

[@CurrentConnected]

Not when you buy from us! Victron warranty is serviced by the distributor that sells it and we make absolute certain that our customers are taken care of every time. We offer an extended 10 year total warranty.

[@marcusaetius9309]

If you compare to inverters like Aims power that has far less features, it has a lower pricetag. The link in the description takes you to a product listing. Prices are subject to change over time, and we don't want to modify the video every time that happens.

I'm interested to hear about this other low frequency rated at this capacity and has this low of an idle draw for less money A certain company that makes green inverters based out of Reno sells a 4kw low-frequency inverter that has 5 times the idle draw, no programmability, no powerassist function, and they have it priced higher than the one shown in this video.

why couldnt the sol-ark 15K hybrid be LF !!!........im still gonna buy 2, but i wouldve preferred a big ole transformer vs the electronic types.

Going from high-voltage DC down to low voltage just to step it back up again has a lower round-trip efficiency. Sol-Ark's have much greater conversion efficiency in utility-interactive systems.
