This Multiplus II is not what I've ordered. But I keep the free upgrade, right?!

[@SuperRockmonkey]

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

[@OffGridGarageAustralia]

Thank you.

[@BobHannent]

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?

[@dennis_m]

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.

[@imval_tech]

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.

[@rvprepperwayne]

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.

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.

[@joetynan5985]

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!

[@OffGridGarageAustralia]

Thanks Joe. I probably piggyback the Multiplus from the Phoenix inverter as others have suggested. That will be a very interesting project.

[@josk5389]

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.

[@andrewradford3953]

That's a nice simple solution. I wonder if much efficiency is lost when charging from external micro inverter AC opposed to local DC?

[@OffGridGarageAustralia]

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.

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.

[@shadowgenesis2877]

From my understanding of the docs for Victron Inverters, the ones with AC in are AC power passthrough, so it doesn't back feed. So even if you connected the inverter to your grid, as long as it doesn't work with the grid tie solar, you be fine using it. Also it can give you an extra power to the batteries for like charging your car on a cloudy day. So I say take the upgrade, and its means you are one step closer to the end too. :P

[@OffGridGarageAustralia]

Thank you. The power company won't allow the inverter to be connected to the grid. As soon as I do this I have upgraded my agreed inverter power. I cannot physically connect any other inverter to the grid as long as the contract runs. But, hey, we're the Off-Grid Garage, right?!

[@servisfibris6679]

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..

[@OffGridGarageAustralia]

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 😉

[@servisfibris6679]

@@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..

While they are being generous...see if you can invest in the future, and the simplicity of having just one box to remember.

[@bishwagit]

Well short description... Can we program this Victron multiplus II as below situations all in togather... 1) When ever the load in more (> 15Ah in AC out put), it will take the help from grid for the additional load ( Total load 26Ah, 15Ah from battery & rest from grid) 2) Battery charge function off always from grid 3) If battery voltage drop below from defined voltage (like 48V DC), it will continue the load from Grid 4) If the battery charge state is > 50%, it will fully use battery only for load for Grid available and not available condition

[@OffGridGarageAustralia]

Thanks Biswajit. 1) Yes, that is possible. The Multi always uses solar and battery power first as much as possible before using any power from the grid. 2) the internal charging function can be completely disabled 3) Yes, that also a standard feature. If the battery is low it uses solar and grid power to power your load. 4) It will use solar and battery power as much and long as possible and only uses the grid if there is not enough power to supply your load.

[@tecnology-today]

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.... ;-)

[@OffGridGarageAustralia]

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.

[@OffGridGarageAustralia]

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...

I remember in the begining before the 3k i ask why not go w 5k so "I told you so!" :D

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.

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!

[@OffGridGarageAustralia]

The Growatt isn't bad either. It does not have all the features but is certainly not a bad device.

[@Sanwizard1]

Keep the Multiplus. The JK can talk CAN I believe, or you can move to a Seplos BMS.

[@reinholdu9909]

There is a CAN adapter for the JK

[@OffGridGarageAustralia]

Yes, that's on my list to connect the BSM to the CAN system and have this all joined together.

[@thomasribbeck390]

So no parallel but serial! As some already mentioned I would put the 3kv as input to the multiplus set power assist to 2000w so you have something like 6,5-7 kw :)

[@OffGridGarageAustralia]

Ahhh, that's a great idea. I haven't read all the comments yet. I said this myself in the video, the Multi can take any AC input 🤷‍♂️ Whole new perspective!

@@OffGridGarageAustralia i did this already with a mix setup to up power my setup for a bigger party :D one 24v 1600 phonix inverter plus on 12v multiplus :D worked 2 days flowless :P

@@thomasribbeck390 it sounds like it worked for two days only...

Yes, serial connection is great option for such offgrid solution. Phoenix first and then multiplus in series. You can also make simple control mechanism which will switch off the phoenix in the case there is no huge power needed. Phoenix standby consumption is reduced then: a) You can use Multiplus assistant to control the multiplus relay based on output power. b) The venusOS is publishing actual power on mqtt topic /Ac/Out/L1/P and by simple low pass filter added to this measure you can switch the phoenix on/off using Multiplus controll relay and have more complex scenarios covered. Node-red is good for start. c) Check the ESS documentaion for further applications. They state ESS is not intended for off-grid solution but in your case it should work perfectly. I assume the multiplus relay will be connected to the phoenix on/off control input.

recon you need to build an electric quad bike for the property... would make a great vid series

[@OffGridGarageAustralia]

The ride-on mower 😉 Got already an appointment for getting the motor mounted 😶

[@wideawaketotruth5301]

If you will eventually need it and your intention was to do that in the future anyway keep it.

[@dougm7796]

Keep it, you will be saving $ in the long run as you wont need to replace when you do need those features.

[@OffGridGarageAustralia]

Until then, there could be Multiplus III on the market with even more cool features.

[@hannesmagnusson4366]

In my opinion, Victron SMART only means that they compatible with the victron app.

[@OffGridGarageAustralia]

Seems that they have Bluetooth, that's all.

[@IndependentNewsMedia]

Install the new kit, old kit donate it to somebody whose life will be improved or a charity, good video 👍

[@rOSScOGITANS]

fantastic inverter, inverter for rich people!! :)

[@OffGridGarageAustralia]

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.

[@Dutch_off_grid_homesteading]

Heya, you have to think about the future if you can so the multi+ II would be my choice

[@Jetiexperte]

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?

[@OffGridGarageAustralia]

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

[@awesomusmaximus3766]

The grid tie shut down ability is also on the Quattro

[@OffGridGarageAustralia]

Effectively the same device just the Quattro has 2 AC inputs and is available in a 15kVA version.

[@nicholaskeur]

Smart in "victron" language only means bluetooth enabled

[@CryptoNut82]

Keep upgrade

[@nhikoid]

Great video. Can't quite believe what I'm seeing here. What an amazing piece of equipment. It looks like this could be used to serve as AC coupled battery manager to retro fit to an existing grid tied PV system??. When Grid AC input is connected, does it actually synchronize it's AC "microgrid with" waveform with the local grid profile. I assume it does, otherwise there would be a fairly loud bang/fizzing.
