Phoenix Inverter Smart with Autotransformer

I'm designing an off grid system and I'd potentially like to use a Phoenix Inverter Smart with a Victron Autotransformer. The photo below is what I want to do:


My question is where should I attach the ground relay control (shown above) and is this setup compatible with the Phoenix Inverter smart?

From the Victron Autotransformer manual (page 3), I see that,


From the Phoenix Inverter Smart manual (page 9), I see that,


Since the system is in a vehicle does that mean I simply need to connect the ground relay control wire to the same ground as the inverter?

Alternative wiring balancer

Hello there,

I read so much about the imporance of equal wire lengths, connector positions etcetera, that I find it a bit strange this concept does not seem to be used in the victron diagram for balancers.

So my question is: Would it be better to wire it, visualised in this picure (purple lines). So that the resistance towards all strings are more equal... Or doesn't matter in case of these balancers?

Looking forward hearing from you people.

All the best:-)

How to convert STP files to 2D vector graphic on a Mac?

I would like to use the 3D STEP (stp) files made available here to produce 2D vector graphics that can then be used to draw schematics.

After several hours exploring and looking around, I failed to uncover something that works on the Mac.

I was able to open the STEP files on several applications:

- FreeCAD: rendering is sub-par. Could not export to SVG or any vector graphic format

- The free stp to stl converter at https://www.makexyz.com/convert/stp-to-stl hangs on "analyzing file…"

- Cheetah 3D can't import stp files, but can import these file formats: .3ds, .dae, .fbx, .obj, .sia, .stl (binary and ASCII), .jas (binary and ASCII). I'm not sure which one would work best or how to convert .stp to it

- Autodesk Fusion 360 can open the file and renders it beautifully but cannot export it to a vector format. It can however convert to a nice png and a few 3D formats

Does anybody have a working solution that would work on a Mac?

Connecting Lithium in parallel


I have an issue with a victron 150ah LiFePO4 (600ah bank of 4 at 12v) not balancing after several attempts. It balances after about 6 hours on hook-up via the multiplus 3000/12/120 but as soon as we boat off it won't balance the next time I charge via engine or geni/multiplus, and BMS shuts down due to one cell (always the same one) going OV at 3.76v

The guy (pro) who fitted the system (now unwell) thinks its a duff battery and has asked that I swap 1 and 4 over to see what happens (cell 4 in battery 1 is the issue)

Now having a look my black BMS cables aren't wired like anything I've seen.

All diagrams I can see the left black cable of Battery1 goes to the left BMS port; the right black cable or B1 goes to B2 left cable; B2 right to B3 left, B3 right goes to battery 4 left and lastly battery 4 right to BMS right port (a 4 battery version of this link https://www.victronenergy.com/blog/2019/07/11/new-veconfigure-manual-new-detailed-marine-schematics-and-dvcc-explained/)

Mine goes B4L-B2R; B4R-B3L; B3R-B1L; B2L-BMSL; B1R-BMSR

I can't find anything wired vaguely similar ANYWHERE. The only possible reason I can see why it was done this way is that my left hand black cable is too short to go to the BMS left port and needs the 2m victron (https://www.victronenergy.com/accessories/m8-circular-connector-male-female-3-pole-cable-2m) extension cable

Q1) is my wiring enough to mess with the cell balancing?
Q2) should I buy the extension cable and wire it as per the diagrams I can find regardless of whether I have a duff battery on not?

Sailboat Multiplus install

Have a 2001 Beneteau 361 with a Xantrex Freedom 20 and failing batteries. Want to upgrade to 300-400Ah LiFePO4 batteries 12V and a Victron 3000W Multiplus.

Have repurposed one of the Victron diagrams to take a stab at the necessary components. 20201011 Beneteau 361 Electrical Schematic.pdf

Would love feedback.

The shore power is currently two 30A 120V circuits. One powers the Air Conditioning and the other goes to the Xantrex Freedom 20. Planning on having one 50A 120V (three wire) plug and a Victron Galvanic Isolator. The single shore power line would feed to the Multiplus, then split with one circuit to the Air Conditioner (would disconnect if shore power is lost) and the other to the AC panel.

The house battery bank would be 3 or 4 100Ah BattleBorn batteries that have internal BMS. Question: Does the 3000W Multiplus require 400Ah battery bank or is 300Ah okay?

The engine start battery is a FLA connected to a 100 A Balmar alternator with a MC-412 regulator. The alternator would directly charge the engine start battery.

A Renogy 50A DC-DC charger with MPPT would connect to the alternator to provide charging to the LiFePO4 battery bank. Solar is planned in the future and would connect to the Renogy DC-DC charger.

A Cerbo GX with the GX Touch 50 display will be purchased and a BMV 712 battery monitor.

Question: There are 3 switches. Wondering if they are configured correctly. The bilge pump is unswitched, as is the Renogy DC-DC charger.

Question: Did not include a Cyrix Li Charge or a Smart Battery Protect. Are these needed? The Battleborn batteries have a low voltage cutoff in the BMS.

Plan on expanding the system to integrate with a Raymarine or B&G suite, tank sensors, remote management, relays, etc.

Wiring help for Victron Orion TR Smart 12 12 30 in motorhome


I am switching over from lead battery in my motorhome and installing a lithium battery. I am attempting to install the Orion-TR Smart DC-DC Charger so the vehicle alternator charges the battery while driving.

  • The Victron doesn’t seem to work properly grounded to the chassis as in the factory configuration. It appears I need to run the ground to the battery post directly?

  • If I ground the lithium battery directly to the Victron instead of the chassis ground is it okay to also keep the ground from the battery for the chassis since the Power Converter needs that ground?

  • Because of the Buss Bar, will it cause “crossing” of the 12. 5 AMPS coming off the alternator mixing with the 14.4 the Victron Orion?

  • The Victron won’t power on unless I have Remote Wire Bridge attached, which the instructions say not to attached until you get the Bluetooth set up, which won’t connect.

How to wire battery disconnect to multiples?


I traded my Xantrex Freedom XC 2000W in for a Victron 12/3000 120/50 120V Multiplus. I love it. On my previous Freedom XC I had a wire with 12V charge that ran from house battery disconnect on my Jayco Seneca 2019 to ACC input port on the back of the Xantrex. This port is designed to be an ignition switch for a work truck, but also works to shut off the inverter when you hit the battery disconnect and don't want to drain the batteries by. continuing using the inverter.

Has anyone wired a similar house battery disconnect to the multiplus? If so, where did you wire it to? Any programming required?

Do I need a circuit breaker?

I'm putting together plans to add solar to my RV and I think I have figured out what I need, but have one open question. I'll be splicing-in the the new power system to the existing AC input line.

Question is: do I need a 30A circuit breaker added to my schematic? The shore power will come out of a 30A breaker, and there's a 30A main breaker on the existing AC/DC distribution panel.

So is it necessary to add yet another breaker where I'm splicing-in the Multiplus?

Hi all, appologies if this has been answered previously but I’ve had no luck finding the answers I need.

I originally had the SCC075015060R - MPPT 75/15 12/24V connected to a solar panel with 1 x 190a & 1 x 100a Lead Acid sealed batteries In my Ford Ranger 2019

I am now wanting to change to DCDC and I think the unit I need is the ORI121236120 - Orion TR Smart 12/12 30A DCDC Charger but was wondering if it is possible to still run the MPPT so I can plug a folding solar blanket when away instead of having to drive around to recharge. (similar to the Redarc units)

Is this setup possible, do I need any extras such as busbars ect? and does anyone have a wiring diagram of a setup like this to put my mind at ease??? I just want to order all parts and tackle it in one hit.

Thankyou all appreciate any help

Newbie like a deer with no eyes...

I apologise profusely, but I really have 'No Eye Deer' how solar panels, 'Killerwasps' and solar regulators work, but I do like having a go at things...

I'm setting up my caravan and have mounted 3 X 175 watt panels on the roof.

The plan is they will feed into 2 X 120 amp deep cycle batteries to run my fridge during the day, that draws 12 amps.

The specs of each panel is:

- Max Power Current 4.93 amps

- Max Power Voltage 35.5 volts

- Open Circuit Voltage 43.5 volts

I know I need to feed the power generated into a Solar Controller, I just don't know which one would meet my needs.

Any advice will be greatly appreciated...

Again, my apologies...

Many questions about my electrical build, any answers appreciated!


Please only answer what you are able to, I know this is a lot of text!

I recently purchased the Orion-Tr Smart 12|12-30 Non-Isolated DC/DC Charger. I'm in the middle of setting up my first solar build for a van. I'm following this wiring diagram for an electrical build, but i'm changing one major component of it. In the diagram, he uses a Li-BIM, which is basically just a battery isolator made for LiFePO4 batteries. I figured since it's not too expensive, and it's much better in the long run, that I would replace that component with the Victron Orion-Tr. I'm really excited to set all of it up, but I do have a few questions about actually finishing the diagram before I purchase the inverter, batteries, and wires.

If there's too many questions, I apologize! I wasn't really sure where to find some of this, so I figured i'd post them on a few forums.

  • So first question.. I attached the new draft of the wiring diagram that i'm currently working on. The main electrical build is almost complete, but I'm not entirely sure how I should connect the Orion. I know the positive out goes to the positive bus bar on my system. But after that, what do I do with the other connections? Does the single, negative ground terminal go all the way back to a new connection on the negative bus bar? Or should it go to a separate grounding connection near the alternator in the hood? or does it simply go back to the same grounding connection that the negative bus bar is attached to?

  • And for the positive in, do I just take a 2AWG wire, and connect the starting battery to the positive input on the Orion? Or do I connect the Orion directly to the alternator somehow? Or both?

  • For the fuse, what kind of fuse is best for this build? And what amperage? My 2001 Ford E150 is using this 130A alternator. In the original wiring diagram, it looks like he's using a 250A terminal fuse, would that be correct for the Orion as well?

  • Also, is that an acceptable amperage to charge my house batteries with? Or do you think there's a possibility of my alternator overheating?

  • Do I need a manual/ignition switch? My understanding is that this is mainly just to override the Orion so that it doesn't turn on when you start the car, if you don't want it to. Or, so you can actually self-jump your starting battery off of your house batteries if you need to in an emergency.

  • In the original wiring diagram, what is the large orange wire with the green, white, and black cable coming out of it? Does the Inverter come with the wiring that i'll need to hook up the inverter to the distribution panel and shore power? What does the 6/3 and 10/3 mean for the wire sizes? I assume the "3" refers to the 3 cables inside of the larger cable, and the first number is the size of the 3 cables inside?

  • Lastly, what kind of distribution panel would you guys recommend? I'm assuming finding a panel that has both a DC fuse box built in, and also an AC breaker box is best. Does anyone have one in mind that they would use in this build?

Again, thank you for literally any feedback at all! I'm completely new to this and sometimes I struggle to find certain pieces of information online myself, so I figure it's best to write down all of the questions I have and ask on a forum like this.

Some support with wiring schema school bus campervan :-)

Hi guys,

We are transforming an old (1997) American School bus to a Campervan / RV / Mobilehome.

We decided to use a 12V system (so no 24V or 48V) because of all kind of equipment we already have.

We have installed 18 flat and bendable solar panels (100W - 18V from a Chinese vendor) on the roof, they are all connected to a Victron Smart MPPT 250/100. the potential total capacity would be 1800W exceeding the 100A (12x 100W = 1200W), but keep in mind that these are Chinese (Ali Express), our tests show roughly 50% - 60% of their specified '100W' performance on a sunny day.

We also bought the following items:

Victron Smart Lithium 12.8V / 200Ah battery
Victron BMS VE.Bus
Victron Smart Phoenix Inverter 12V/3000W
Victron Smart Battery Protect 12V/220A
Victron Smart Phoenix Charger 12V/50A (1+1)

The idea is be to fully off-the-grid capable, even on days with less sun (therefore the solar panel overkill, and because we simply have a very big roof).

I do have quite some experience with electric systems in general (both AC and DC) but I'm not 100% sure about the VE.bus wiring. So it would be very helpfull if someone could help me with some wiring schema / diagram.

MultiPlus II AC bypass switch help

I've just read the Wiring Unlimited guide - what an amazing and educational resource! Thank you so much to Victron and Margreet Leeftink for writing this, I've really learnt so much about some basic electrical theory.

There's an interesting section in the guide where it suggests running a bypass switch.


This makes complete sense in order to isolate the inverter from the grid and loads in order to be able to do maintenance etc. but I have a couple of questions:

  1. Is a "bypass switch" the same thing as a "changeover switch" such as the Hager SF463? https://www.hagerelectro.com.au/e-catalogue/energy-distribution/control-indication/manual-changeover-switches/changeover-switches/sf463/18978.htm
  2. If it's the same as a changeover switch, how would the switch be wired logically? I've tried working this out but it's not making sense to me and I'm hoping someone might be able to help me understand how this should work?

I've got a diagram below which is how I think it should be wired but I'm trying to understand where the AC-In would be wired to.

I thought maybe that AC-In would be wired into the changeover switch in parallel with the AC-out but I thought this might introduce a loop and this would be a bad idea?

Then I thought maybe it should be wired into the output of the MCB but then I'd have to add an isolator and this didn't make sense and doesn't follow the schematic depicted in the wiring unlimited guide.

Would really appreciate some help here from some experts :)
