- The inverter upgrade is one of the many changes we have to make with the battery shelf coming online soon. The existing 3kVA inverter is not enough to deliver all the energy from our 45kWh battery.
I wanted to upgrade to a Victron Phoenix inverter which we can parallel later to increase the power output. Springers Solar didn't haven one in stock and send the Multiplus II as a free upgrade. The Multi has some really cool features which I cannot use right now. Should I keep it anyway?

Great inverter. You can actually daisy chain the Multiplus II after the Phoenix. Connect the Phoenix on the input of the Multiplus II and the Multiplus II will be able to supplement the power if the Phoenix doesn't have enough capacity.
Absolutely keep it! In fact, keep the MP2, sell off the old inverter and put the $$ towards a 2nd MP2 and enjoy have 10Kva at your disposal. You’ll need it down the track. If you install x2 inverters now you won’t need to change your wiring in the future
Thank you.
Finally catching up on videos I have missed. Awesome Andy 👍👍
Keep it. We'll all look forward to your expert content for this device.
Awesome upgrade, seems a lot like the Outback Radian inverter that we run here. It is a 8KW inverter that is made up of 2 4KW modules. Using split phase 240V here.
I love the new Victron! That's exactly what I'd like to see, including the parallelization option. Would be great if you buy another one and show the parallelization.
Btw, just now I found your link to the victron dashboard, it's amazing how much data you are providing there. Thanks a lot!
Thanks Robert. In the first step I will use the old inverter as the AC input to the Multi and see how this goes. But yeah, later down the track we will have multiple Multis 😉
Hello from Norway! I just want to thank you for all the fantastic videos! Realy informative and educating. Always starting with a smile, and happy face! Thanks.
I have now started my own jurney towards offgrid cabin up in the Nowegian forrest.. i use li-ion ev (bmw) batteries, 4.7v/cell ,- 24v -300amp. Now installing the Qucc 200a bms. And 24v/3000w inverter.
Fantastic to follow you on your testing and learning prosess, we all learn something! Thanks. Runar.
Thanks so much for your comment and kind words. I try my best to keep you all educated and entertained. It always great to read from others and that my videos actually make a difference and encourage others to do their own projects.
Thank you very much again, Runar.
I’m so impressed off grid garage has become one of the most watchable videos just seem to relate makes sense to hookup a community project can’t wait I’m well excited get the whole town together with free energy love it you will always be professional Andy I love that people are sending you beers next it will the amazing out there dinners dude you’re on a winner!!!
Wow, thanks so much for your kind words and feedback.
Like many people say. Two is one and one is none. It is better to have a spare inverter in case of problem. Maybe one for the garage ant the other por the house. Specially when your on track ends and you try to run the house of grid. Nice work Andy. I learn a lot with you.
Keep the free upgrade Andy! Looking forward to "experience sharing" of the new inverter.
Those features sound very similar to the MPP Solar/voltronic power infinisolar V2 hybrid inverter, but it has solar charge controller and grid tie feed in the inverter itself along with all the usual features like AC charger, parallel, communication at a fraction of the victron price. I don't know how they do it. Anyways that inverter won't satisfy local requirements for grid tie I guess, but still worth a mention.
Thats the same device i have running my entire house here in South Africa, great piece of kit
Interesting. Is it connected to the grid as well or completely off-grid?
Hello from the high desert of New Mexico USA 🇺🇸. Hi Andy I'm glad to hear about the free upgrade. I would say, keep the Multiplus 2 and see if Springers will take in your old inverter as trade credit for a second Multiplus 2. Keep up the good work and stay safe and charged. May God bless you and your family
Thank you James. All the best to NM! Stay safe.
Hey Andy, Keep the multiplus I have been using one for a few years and it has options that you don't even know you need until one day you want to try something and then you realise that all you have to do is enable it. it has saved me buying additional equipment so many times.
Good to know!
Andy, As a Solar installer I can tell you the MP2 is a very robust unit. However it does have a flaw that I don't like. The A/C input is a push style connector and not a screw type. Using a ferrule on the end of the wire does help inserting the wire but it don't crush to give you a full wire contact. Bare wire is harder to insert. But has a much better contact area. I wish they would of used the screw style terminal on the MP2 like they did on other models.
Mine has screws, I'm sure. Maybe they have changed that at some stage... I'll pay attention to it again when I have the cover open.
@@OffGridGarageAustralia mine too has screws
Keep the Multi Plus, if you can't spend out initially just split the loads across the inverters and then later you can sell the Phoenix to buy the next MultiPlus.
Or perhaps see if the supplier would be willing to do a trade-in on the Phoenix now to upgrade your system sooner rather than later?
Hi. I just found your channel, it's got amazing content. Makes me recall my days of building my own computers. I am keen to build a grid tied battery system and interested to get a feeling of the cost/benefit versus a powerwall or equivalent. I'm wondering if.you have a video covering anything like this?
Thanks Andy
Keep it. As for others that do it, I believe the Sol-Ark / Sunsynk / Deye 8/12/15kw (which are regional rebrands with minor changes) can do these things the Multiplus 2 can. Good video!
Keep the upgrade. Sounds like it might be nice to have the options later.
Hello Andy,
Just a quick message from a french frog. I subscribed to your channel last month and I wanted to thank you for sharing so much. You made me triggering the decision of starting a ESS project for my house.
And - guess what - the device I ordered and received a couple of days ago is a Multiplus II 5KvA !
I would love to share my experience with you as well.
Thanks again so much.
Thank you Stéph. That is great feedback and I really appreciate it.
Woohoo, go team blue. I really like the Victron gear. It's more expensive, but the features and quality is outstanding.
Thank you and all the greetings to France!
Outback does the frequency change to modulate gridtie inverter power also. They were doing that many years go.
Keep it, you'll want it for the grid-tie.
Sell your phoenix later and upgrade to 2x multi-pluses.
You won't regret it. (More is always better!!!)
Hi mate great upgrade I have Multiplus2 3000 inverter in my Amarok canopy and love it.
Good to hear! Thank you.
Stick to the plan mate... don't get sidetracked by new shiny toys, but in saying that, sounds like it will be a sweet setup if you can hook it up to the house system to change your batteries 🔋 👍
I think a have the Same model. Please keep it for my learning curve to go higher
Hahaha, great reason to keep it😂
Just getting into home power storage / PV / LFP. The MP2's looked great until I realised they don't have MPPT built-in like some of the Growatts/Sol Arks/ etc. I've been following your journey and really enjoying it. Keen to learn more. I'm in Brissie - Manly/Wynnum suburbs...
Can you install old inverter as "generator" to multiplus? So not paralleling them but serialising them? 3kW unit makes power when there is no big loads and multiplus kicks in when there is. I have no idea is this possible, but it would allow using both inverters.
Thats what i also thought first
Yes, that's what others have suggested, so we will give this a go...
@@OffGridGarageAustralia Cool!
Andy, my suggestion is to keep it. And maybe Victron should donate a second multiplus II ( it would allow you to create a master/slave arrangement, more complex wiring diagrams, trial your domestic installation, etc ). Your content on batteries is amazing and I'm willing to bet the content on the inverters/ grid charge controller ( multiplus ) would be considerably better than Victrons. Keep up the good work!
Thanks Joe. I probably piggyback the Multiplus from the Phoenix inverter as others have suggested. That will be a very interesting project.
This video age'd well, Recently found your youtube channel and I've watched these videos backwards
Keep it. Even if you dont need the additional Features now, maybee they come handy in the future.
I think the SMA Sunny Island 8 has similar features (if you stick to their brand solar inverters, home manager etc).
I think you should keep it, even if you don't use the extra features, it will give you a lot of future options if you ever want to completely disconnect from the grid.
You could then sell the phoenix
Use the 3kw as grid and the 5 kw as second that can work if the multi + can limit ac current from you 3kw
He can't yet or he loses his "sell contract".
I mean 3kw inverter to play as grid in the multi plus
And get 8 kw
Yes, Krille. That's a good idea and an amazing project to come.
I love the Victron Multiplus II. I believe the phenix inverter can be used for another project or sold off, so that leaves you with some funds to get a new Multiplus II for increased power output through paralleling. Have a great week
Thanks Nsikan. Or, as other commented, I can use the smaller inverter as the input for the Multiplus... Let's see if this works.
I am eagerly looking forward to that.
You could use the Phoenix inverter to create a mobile power Although you have solar close to your house a mobile source with more power and capacity than a Bluetti might prove useful.
I have used a Multi plus with 29.5kwh battery in a small camping trailer to do this. I am in the process of building a second one so that energy can be moved and is always available much like having two batteries in a cordless drill. This is important to me as my solar array is about 1.5km away from my house.
I still have the XIIJA inverter as well. It is much smaller but has also 3kW. I safe this for the lawn mower once it's converted to run the electric chainsaw or the mulcher off it...
Do it right the first time. Keeping the multiples saves a lot of headache later on
Hey Andy, I would keep the upgrade. Building my ESS around this Inverter/charger. Possibility's are endless with this one. As soon as your contract ends, you could hook this one up the grid, when energy intake is low. And that for the Phoenix price, not bad.
Yes, thank you Frans.
Do I need a PV inverter to set up a AC tied System? I would like to use the Solar power if available and add from the grid what is needed in real time. If I don't use enough or any power it should charge the Battery and if the Battery is full it should put the overflow energy into the grid. I got a Multiplus 12/300/120-16 (not II) an Victon mppt and BMV. What else would I need to set this up?
That's exactly how the system will work. You maybe want a Victron energy meter as well to control what is coming in from the grid, so the Multi can act accordingly.
The ESS design and installation manual gives you all the info:
www.victronenergy.com/media/pg/Energy_Storage_System/en/index-en.html
Thanks
Thank you very much!
i like the idea of a built in charger just incase they is really bad weather one could use a generator
Can you feed in the output of the off-grid inverter into the PV-AC of the Multipass II for a microgrid?
That's what I have done!
@@OffGridGarageAustralia I'm in love. I want one, but I don't like the price tag.
You are giving me the information i need for my project.
I want to connect a 230volt output solar system (Only works if there is a 230volt "input") to the input of the multiplus. And you confirm this wil work because the multiplus creates a own 230v field in the multiplus.
Thanks you for thus critical information. I already have a 3000whatss inverter, so iam need to think if iam going to keep this. Or sell it and buy a bigger multiplus converter...
thank you sir!!
I remember in the begining before the 3k i ask why not go w 5k so "I told you so!" :D
Yeah, I know... many people have questioned that. 3kVA is workable for what I use the system for as I can shift loads so they don't run at the same time. But now with the larger battery coming online soon, I want to see how far I can get with a larger inverter. And the Multiplus may be capable to use the smaller inverter as its input AC power so we can piggyback them. That would be an interesting project.
“Smart” means that device has a Bluetooth support. It’s general pattern for all Victron Energy products
Battery 3.0 - are we talking Megawatt hours Andy? ⚡⚡
Hahaha, I have enough space in the garage.
Can you feed the old inverter into the new one as a microgrid. Then have that power source charge the batteries?
Yes, that should be possible! Great idea!
Hi, actually i was following the other new LF inverter by the name Multi RS Solar which i have been told cannot be used as AC couple like the multiplus ii does. Since i already have grid tie Fronius inverter, does this hold true that i need to grab a multplusses rather than the new Multi Solar RS?
you could use the extra inverter in the off-grid shed.
Does your model have the relay that can be activated when your battery at a set % to dump power into say a hot water heater?
As they create their own microgrid, you can add SOME models of grid connected inverters up to the rating of the Victron 5000VA =~ 4kW. So about 8kW. You'll need much more roof space!
When I bought easysolar 5kva(hardly used) the screen wouldn't work. Ended up being the inline fuse along the power wire to the screen had broken its fuse wire during transport. It was a bugger to find behind a large board inside.
Look forward to you new adventure.
Yes, it has a programmable relay. Not sure what trigger points can be set for this but hot water or vehicle charging would be great.
The Multis have the 1.0 rule so can cope with 5kW of AC solar for a 5kVA inverter. That's exactly what I have right now. If I upgrade to another 5kVA Multi I can hook up another 5kW of AC coupled solar.
I have heaps of roof space on the house and this is a great way to connect more solar from this location to my battery without extra wiring.
@@OffGridGarageAustralia Nice and simple via the existing AC to the garage. Hope it's not too shady on the house, unlike the shed.
Another interesting question Will I be able to discharge my batteries into the city network . The question is whether the wind in the program will have such an opportunity to transfer energy from batteries to the city network ?
Keep it they are great
If I connect the multiplus to an existing system that has a grid inverter .It creates 220 at its output terminals so that the network inverter understands that it is connected to the network when in fact there is no network. As far as I understood it then. The Quadro also has this feature.?
Yes, you can connect grid inverters either at the input of the Multi/Quattro or the output. If the grid fails, your grid inverter will fail as well if connected to the input but if connected to the output of the multi, it sees the micro grid of the Multi and keeps working. There are rules and boundaries for that but it works quite well.
www.victronenergy.com/live/ac_coupling:start
Use the Phoenix for the car charger circuit and the new one for everything else.
This is what I was thinking as well.
Yes, something like this...
*NOBRAINER* ... It's the best ... _Off-Grid Garage_ NEEDS z'Best, the MultiPlus II 👍 👍👍 I'm sure some of your compatriots are happy it's already in AUS
Victrons "smart" demarcation I believe refers to whether the device has built in Bluetooth or not, that's it. If you're running every device to a GX monitoring unit then there's no need to buy the "smart" versions of the devices
Yes, that's correct, I still like the alternative way to connect via BT to a specific device. In case your GX is not working you would need to hook up a laptop and a VE.direct cable to the device to control it.
I will take it if you don't want it
Hahaha, I believe you!
One more little question :) If I have 3 invector to create three phases System, When I install 3 inverters I can use separate batteries for each inverter? The idea is that at the moment I have 40 kW lithium cells from an electric car in I want to use them for the first inverter, And for the second and third inverter I want to use lithium iron batteries .In the first variant, I will have an assembly of 13 s In the second variant, I will have an assembly of 16 s. I can separately set up charging on each inverter, one for charging lit-ion batteries and the other for charging lithium-iron batteries ?
I reckon either keep the Phoenix 3000 and use it as a dedicated Tesla charger, or sell it to help fund a second MP2, but definitely keep the MP2. Free upgrades are always welcomed
can the phoenix AC output be fed into the multiplus 2 AC input (only make sense if you have 2 battery setup) otherwise run some other independent circuits (pool only perhaps) or perhaps that company will take it as a trade in? I use PIP5048MS they have AC in to charge the battery (as well as solar CC) or you can run the PIP like a UPS. During the years I got upgrades on some batteries and also later model PIP5048MG pips which can take 450V input compared to 145V. So plan still a plan is if 5048MG run down to 30 SOC then then the 5048MS could feed power as it will be a lighter loaded circuit..
Why does it only make sense with a 2 battery setup. Both inverters can be fed by the same battery and produce power. I have to disable the charger in the Multi because that would be stupid.
@@OffGridGarageAustralia In my situation I have 2 sets of batteries one set is 220AH at 48V the other 330AH at 48V and 2 incompatible PIP series inverters. So I could charge up the 330AH on the idle 220AH down to 70%SOC then charge it up when the sun is out. This would only be the case should the 330AH get near or below 70SOC (30% discharged). Its just a way to move power around when one has incompatible batteries without additional expenditure. I am not aware of being able to combine different AH ratings of same voltage without impacting on them (perhaps some DC to DC converter, but for 48V and the amperage that could be expensive and I already have a redundant PIP inverter). Just a situation in life where products are superseded and aren't compatible combining in amorphous grid. Annoying as I bought PIP5048MS (asked vendor did they have anything coming out soonish to do higher solar input voltage, they said no and 6 months later on their website were the 5048MGs - grrr)
@@rw-xf4cb you can definitely parallel your battery banks without any issues if they are from the same chemistry and have their own BMS each. I made the test about that here in there channel a few videos back and paralleled a 5Ah battery with 304Ah bank. No problem, just worked...
@@OffGridGarageAustralia I have 330AH AGM and 220AH SLA (both lead acid) and don't have a BMS in between them and the inverters. I guess one could put a BMS between each array...When they come up for retirement will definitely look at buying LiFePO or whatever the new fandangled technology will be (subject to costs)...
Many solar inverter systems have higher voltage. For 3.0 you could do the server rack batteries with Solar Edge or Schneider. The efficiency is 98%+.
Hi Andy, great video! Maybe you need to upgrade your member count also ;-) it’s going up.
Thanks, yeah, I know. I keep it for a while maybe until 27435 or something 😄
Next project… digital member counter in the off grid garage.
There might be an interesting aspect when using the Victron inverters. As from my experience the Victron MultiPlus is not capable in feeding half-sinus loads and/or loads connected with a dimmer/speed-regulator. Half-sinus loads by means of a diode in the live connection to reduce the peak power. Using high frequency CN inverters, do not have this problem. Something to consider for future use when connecting the total domain? Salut, Peter Bovekerk
Thanks Peter, all dimmers and motor regulators I have are fully electronic, so should not have this problem.
can you see if they will give you a deal on trading in your current inverter for a second multi plus ?
I don't really need a second one at the moment but I can try...
Can connect 3000 ac to ac input on the 5000 to get some more out of it. :) If it good and works is another question. Maybe better to use them as two seperate circuits for different loads as mentioned, good for redundancy if one would fail. You can still paralell two if you buy any one of them again.
Apparently they can be piggybacked, so this will be the next project...
Hi Andy, I always wondered If you were familiar with the sma sunny island inverters. Mate, you need a forklift to handle the si6.0 @ a whopping 60kg! They are built like German tank! (ip65) They do everything you just described your multi does. I have two si6.0' ready to fire up soon, off grid, coupled with some sma sunny boys (also German tanks!) The sunny islands are complex and I only have my learner licence so should be fun. I'm super happy you got a new inverter with all the same features as the Islands cos I know I'm going to learn even more from you now 😁 seriously, you and your vids are the best!
This sounds a great piece of equipment.I have a big question: what are the pros and cons of using a solar MPPT to AC and a solar MPPT to the battery DC?
Solar Mppt to DC is more efficient. 1 thing I know 😂✌️
Yes, Janis is correct. MPPTs are the most efficient way to charge your batteries. They have the least losses and adapt the fastest to changing conditions.
This is not clear. My opinion, which is based on nothing at all: If you use solar MPPT to DC means that you cannot inject on the grid, so only worth if the battery is big or if you have no grid at all. Besides, solar MPPT to AC might be more efficient if yo are using the electricity straight, since there are fewer transformation steps. So a hybrid with both AC and DC MPPT might be a better option. This is just an intuition...
Take the win. :)
hi Andy. keep it, of course. In the other hand, you mentioned a very interesting feature (emulating a grid). If I understood well, and this inverter is able to do so, you can connect an aditional "on grid" inverter since this type of inverters need to sense the grid´s voltage wave to mimic the power to be supplied (no grid= no power even if you have full of sun in the panels). In this case you can have electricity supply even in case of the grid is off. I think it is a nice feature and some interesting to show in a future video.... ;-)
Yes, that's exactly the third feature I was talkig about in the video. Even in an off-grid installation, you can still use your grid-tied inverters and solar. Only a few inverters will work this way though as they need to react to the frequency shifting of the Multi. Also, there is a rule that the AC coupled solar cannot exceed the inverter power, so 5kW of solar can be connected to a 5kVA inverter, but not more AC solar.
More info here: www.victronenergy.com/live/ac_coupling:start#:~:text=In%20both%20grid%2Dconnected%20and,3.000%20Wp%20installed%20solar%20power.
The Tesla Powerwall 2 does the same trick in shifting its generated power mains frequency to control a grid connected inverter.
Didn't know that... It's a cool feature
old inverter could feed a single socket for the car only on a separate circuit?
Or, the old inverter could feed the input of the new one. Some say here that's possible...
@@OffGridGarageAustralia That Definitely sounds possible as long as the New inverter never tries to feed power back towards the old inverter!
Just mounted my MP2 48 5000/70 , what a beast!. Included a Cerbo lus smartshunt and will connect a smartsolar 250/100, 250/70 and 150/30 in order to run on batteries during the summer. Victron is LEGO for nerds LOL.
Hahaha, great analogy.
so you mean to say that this multi-plus unit has a feature that acts like a limiter. can you further expand on this subject. Thanks
question?? how long would it take you to replace that inverter with another one? (it blew up). would it not make sense to hook them both up and mothball or light load the other? As for the upgrade- if you bought a tv- car- widget and they could not get it only with the features you wanted but the next model up had that and more for the same money would you say no or would you smile and say thank you for thinking of me? How long can you hook it up to the grid to "test" it i wonder. or hook to genset. i see many more vids coming
Thanks Marte. As others said here it might be possible to use the old inverter as the 'grid' for the new one and series connect the inverter. That would give me 8kVA on total power. I cannot hook the new one up to the grid though as long as the contract runs...
Hi andy does the 8000 OR 5000 MPPSOLAR DO THE SAME TRICK AS WHAT U HAVE BEEN GIVEN?THIS UNIT I REFER TO IS WHAT I USE ONLY I DIDNT CONECT MINE TO THE GRID, THERE IS PROVISION FOR GRID CONECT ON IT.CHEERS RENE.
Yeah, but can it also handle AC coupled solar in an off-grid situation?
Can you please test the multiplus for us, and show us how it performs in overload (5000w 30min) or surge (9000w 2 min) situations?
I'll see what I can do...
Is the multiplus II a low frequency inverter?
fantastic inverter, inverter for rich people!! :)
It will last. I don't want to pay several times for an inverter with all the hassle of having no power if a cheap one fails.
The grid tie shut down ability is also on the Quattro
Effectively the same device just the Quattro has 2 AC inputs and is available in a 15kVA version.
Hi Andy happy new year.
I think that you can use the old inverter to power the car because othervise if you charge the car via the Multiplus it can overloaded.
And because if you buy another Multiplus at the moment is not necessary because you can't connect the house to the garage at the moment do to the AC couppling.
The car can handle up to 11kW 3-phase wile charging from AC but also as little as 1.2kW. It will adapt to the power source I connect it to.
Keep the old one as redundancy or for your own experiments, later on down the line, change it for another multi plus II, you can then parallel them and more if needed in the further future.
Would be curious how much power you use/ send back to the grid from the house in a future video. Then we can all start thinking up idea’s on future community projects for ya 😄
The house produces around 22-25kWh on a good summer day and around 10kWh in winter when the sun is a bit lower. The roof points to the east so it's not optimal and there are also large trees which cause shading in the morning and during winter time.
Export in Summer: 13kWh per day
Export in Winter: 7.5kWh per day
The solar on the house takes up around 20% of the available roof space, so there is more potential...
@@OffGridGarageAustralia alright, well heck you might have some perpetual motion going soon lol
TH-cam pays for more solar and and you sell the power back to the grid and you buy more solar to you run out of roof space that is haha 😄
Very fun channel you got going. Just don’t forget to stay charged 😉
Use the phoenix in a go-rack/dolly for power :)
Stick to your plans . You are the only person that can make that decision . Andy knows best .
Victron is just too expensive for me, I can only afford a growatt inverter at the moment, it is good to see you have free upgrade to mp2!
The Growatt isn't bad either. It does not have all the features but is certainly not a bad device.
Well, is it not possible to use the old Phoenix Inverter as AC-IN feed for the new Multiplus? In this case the Multiplus would synchronise to the Phoenix Output microgrid and you should be able to use the 3kVA off the Phoenix + the 5kVA of the Mutlipus = 8kVA on one phase. Maybe you will need an additional Victron current sensor on the phoenix Output to make sure, that the Mutliplus will never try to deliver power in this "grid" of the Phoenix (Nulleinspeisung).
Yes, that's a fantastic idea and will be a great project. I'll see what I can find.
It should not send any power to the grid as the AC coupled solar is not connected to this system. I don't think it will export power from the MPPTs to the grid but I might be wrong about this...
hi Andy keep keep keep you're lucky man
i received mine a few weeks ago. large inverter and so many possibilities.
but you will have to invest some more....
For any programming needs you will still need the MK3 to USB adapter of a cerbo and a computer or tablet.
And the MultiPlus line does not have BT built in.
I already use this a lot, here in the winter here in Europe
one of the possibilities is that you can plan your loads, and also start charging at 20% and stop at 70% or just charge 5h00 etc.
The MK3 adapter was in the box. I ordered this at the same time 🤭
AAAA Andy 14:00 minute: Yes you can feed 5000VA Multi with 3000VA Phoenix to have 8000VA. The 3000VA Phoenix is just 3000VA "non-gasoline" generator. Put it on input (L1-in) and then use transfer switch and power assist of 5000VA Multi with set up to to 2x power assist and that input is capable only 10A ;) Just don't couple it with AC/coupled solar, because Multi will think that there is grid power and push it out. But! There is also a possibility to use current measurement inside or external and set multi to not export to grid (keep amps on 0 on that current measuremet) and then there is some possible way to even keep ac coupled solar, two inverters and not pay for another 5000VA Multi..
That is a fantastic idea!!! Will this work or just making a lot of magic smoke and a brilliant video?
I can set the multi to zero export with a meter or current sensor as you said. But yeah, for the next few years I won't be connecting the AC solar. It needs to feed in 😉
@@OffGridGarageAustralia DC and AC are isolated on both devices to my knowledge, so there should be no smoke.. You can't connect them in PARALEL as they can not sync, even different models of Multi can't be operated in PARALEL. But serializing them is possible :) There is also a small problem - you can not use whole capacity of inverter as they can provide overload currents for few seconds. This is not possible as you set fixed current on input. But longterm inverting is possible. Another thing that you may take into account is that when Phoenix is overheated, it will provide less AC current, so if you set 10A on input of Multi+ and you have Phoenix over 40°C it will shut down - this can be another reason to not fully use 10A capacity of your Phoenix..
@@servisfibris6679 great, thank you. I was thinking about the limited output of the Phoenix dependent on the temperature, so I have to set it to a safe number or change it between summer and winter.
Thanks again.
@@servisfibris6679 Yep, the limitations of paralleling these inverters are well known.
I have posted a question in the Victron Community page to se if I get any responses in regards to that:
community.victronenergy.com/questions/115103/output-of-phoenix-smart-inverter-feeds-ac-input-of.html
if i understand you correctly the Phenox is in short supply < why explain your situation to your supplier and see if they have a trade in option for you to get another multi plus 2 ?
Keep it, I run a Quattro and a Fronius in in a Micro grid, its awsome
Ah great. The Quattro does the same thing and throttles the Fronius down once the battery is full.
@@OffGridGarageAustralia Yes indeed, the frequency control works great. ESS needs to be enabled on the Multi. Even tho Victron does not recommend ESS for off grid, it works 💯
Keep both. The "smart" can be used for poolpump as a non essential seperate nanogrid. I Belive in having seperate smaller, prioritized systems instead of One. If the One fails, all is out.
Andy, I've been running exactly the same device since last Thursday. And one or the other setting on my device is not yet optimal. I clearly need your expertise. Therefore, you are not allowed to give up the multi again. :) Greetings from the alte Heimat.
Thank you. It will be hanging on the wall soon and we do some proper testing then 😉
@@OffGridGarageAustralia That's great - I'm looking forward to it
Keep the MultiPlus II! You'll use the features eventually. Keep the old inverter as a spare, or even use it to power another fuse box with specific loads.
Thank you very much for your reply. I have a photo electrical system for 20 kW The system consists of four circles of photovoltaic panels of 800 v each . But I want to make it also autonomous, that is, use batteries. It is no coincidence that your video saw that the wind has the ability to create its own micro network to work with a network ivector. I was very happy about this and immediately the question arose Which invector should I buy Quadro or multiplus :) For three days I lived with this thought that I need to buy a multiplus or Quadro inverter. And now I understand. By how much I have a three-phase network inverter, it means I need to buy three multiplus inverters :(
I wonder if it would be possible to let the Phoenix Inverter be the AC in of the MultiPlus II ? Just in case you need more than 5000 VA for a short time. Anyways congratulations to the new Inverter. I bought myself the same one end of last year for my future 48v island project. :-)
Yes, that should be possible as others have commented here. So that will be an interesting project!
Hi Andy, kannst du den MP2 nicht über AC In mit dem Phoenix kombinieren?
Hi Andy, can't you combine the MP2 with the Phoenix via AC In?
Ja, das sollte funktionieren...
Starker Typ!! Nicht im Bizeps!! 😉
It sounds like they intentionally chose to give you the upgrade for free (not by mistake). Definitely keep it! I bet you can hook it to the 3kw to use them together...
They are a really good company, and Andy is a totally nice guy.
I asked with other companies as well and the Phoenix inverter was on backorder everywhere, so I guess, the Multi is the way to go...
Keep the Multiplus 2. With it you can add PV Panels with Micro invertes. So everywhere you‘ve got power and want solar just add 1-4 panels with a microinverter. The microinverter must sense power frequenzy und if it goes above 50.2 Hz the inverter must start to reduce output. Obove 51.5 Hz at 50% reduced output they must shut down. The norm that sets this is the VDE-AR-N 4105 in Germany.
That's a nice simple solution.
I wonder if much efficiency is lost when charging from external micro inverter AC opposed to local DC?
I heard this from Jens (Meine Energiewende). He told me that his Micro Inverter shut down once his Multis will increase the frequency. That's an interesting feature. You still need to watch the 1.0 rule for the Victron Multi in doing this.
I think people are more likely to want a Multiplus, even if you don't need the extra features. In otherwords, there is a bigger audience that wants to see you implement a system using this.
Yes, definitely. The Multiplus is the way to go and I think this is the reason there is a shortage for the Phoenix inverters, Victron wants to push the Multi. It would make sense to have only one device instead of several ( Multi, Phoenix and Quattro).
Sometimes, they prefer ship what they have readily available. Just check with them. This way if there is a warranty issue you will not be ashamed to ask for support!
