Looking for a quick review on this schematic, though not sure if this is the right place for it. Can someone experienced give me some feedback? Thanks in advance.
Currently I am working on a simple setup for a camper. I would like to ask you to check if this setup is correct or if I still need to adjust something here.
For now I only want to use shore power to charge the battery and in the future I want to expand this with solar panels.
I do not intend to connect this setup to the alternator for the time being.
Victron Energy produces loads of great schematic drawings to help you plan your wiring. This is the first in a series of schematic drawings and it features the new Lynx Smart BMS together with the MultiPlus II with two 120v circuits. You can see there is solar and alternator charging as this is would be a complex install for an RV in the US for example.
Here is a link to the full-sized pdf.
We have been struggling to figure out all of the components needed to setup a 24v system in our RV. We have 4 255w solar panels, Victron Multiplus 3000, Victron 150|35 MPPT, and after much debate between Tesla modules, and Battleborn batteries, we are going with Battleborn.
We have also been looking at the Orion converters but do not know whether to go with an isolated or non-isolated one. We also were looking at the Victron Octo GX to control it all.

Victron has updated its Pylontech Wiring. See the picture below.
In the version before, the GND cable was connected to the negative pole of the DC Distributor.
Now they have excluded the GND cable at the negative pole of the DC distributor. So the system is not grounded at the negative pole anymore.
Why did they change it?
Is it true, that the negative pole of the Battery is connected to Ground over the case Ground, as this fellow says:
I have read in the MPPT manual:
WARNING: WHEN A GROUND FAULT IS INDICATED, BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE UNGROUNDED AND HAZARDOUS.
So the MPPT should be grounded on the negative pole am I right?
Je viens de terminer le schéma de l'installation que je souhaite obtenir. Je le soumet à votre critique pour savoir si elle est correcte, améliorable ou complètement fausse, avant de passer diverses commandes.
Notes : La puissance totale des panneaux est correcte pour mes besoins. Un seul MPPT 150/45 semble suffisant avec le calculateur Victron, mais j'en ai mis deux pour parer à d'éventuels problèmes sur un panneau solaire ou un MPPT. Je ne sais pas comment tout mettre à la terre et le câble nécessaire entre l'onduleur et le coffret électrique.
Vous pouvez à loisir modifier ce schéma :)
Merci de m'avoir lu.
I have finished my first revision of the campervan schematics, I am sure I would have forgotten a few items (such as the Dometic fridge, a shower solution etc), but this is the general installation. I wanted some people to check it over and to see if everything looks legit in terms of wiring etc. I suspect the solar wattage should be enough considering I have the DC-DC charger? Also in terms of AC power, can someone advise on a suitable distribution box that will work seamlessly with the Multiplus and the correct wire sizes for this also please?
Let me know if anything looks wrong. I plan to fit what I can and get it approved by an electrician.
I've got a few Victron items on order (for a boat) and one of them is a Multiplus 12 | 3000 | 120. I'm installing this as part of an AC refresh, which will include moving from twin 120V 30A single phase inlets to a 120/240V 50A split phase. We have some favourite marinas that only provide a single 120V 30A dock outlet, which is why I've incorporated that into the design. This is AC only and doesn't show solar, Cerbo GX or the shunt, etc.
This is my first revision with the Victron in place, if you have a few minutes, please provide constructive criticism. Note, the contactor is there to provide higher capacity for switched loads running through the inverter and still allow all the features that the inverter provides to operate, such as power assist.
One of my questions is around circuit grounding for devices on the output side of the inverter (AC1 and AC2). As I've drawn it, there will be 2 ground busses - one before the inverter and one after. This is consistent with the schematics I've seen on the Victron site. I have seen other places where there is only one ground buss for everything - devices before and after the inverter share the same buss. Which is correct?
Thank you in advance for taking the time to assist!
Just wondering if there will be any updated schematics made available?
Specifically ones incorportating a multiplus, MPPT, lithiums, ve.bus bms, gx touch 50 etc etc
Hi I am answering my own question really , i asked about software for doing schematics, i have downloaded Smartdraw and must admit it looks nearly as good as the Victron ones albeit i have had to download images of the components from the web and they are not always that good but with a bit of messing about not too bad at all.
Je viens de visionner une vidéo réalisée par Victron au sujet d'une course autour du monde de voiliers qui aura lieu en 2022.
Tout à la fin de la vidéo à 15 min 10 sec, on peut voir brièvement le schéma électrique de l'installation Victron sur ce bateau.
Savez-vous où peut-on se procurer le schéma au format pdf ?
I am trying to find the correct bolt/terminal sizes for the Multiplus 230V 5000VA and Autotransformer 100A. I have found scattered information in different manuals and am getting a bit frustrated. Can anyone point me to the correct documentation where this is available.
i.e. AC Input and Output, ground (internal and case), battery connections...etc
I see so many nicely drawn system schematic diagrams - is there a Victron product image library available?
I am having difficulty loading the victron symbols for use in .io any suggestions?
Since yesterday the Cerbo GX manual is ready to download here.
Was a bit surprised that the Cerbo is powered by the Load disconnect from the VE.Bus BMS, but that is how the manual reads.
I finally was able to finish the schematic wiring for the new setup.
Maybe someone can have a look and check the schematic and see if it is acceptable?
I'm having some difficulty understanding how I can connect the BatteryProtect (12v/65a) with the MultiPlus 12/800/35. The MultiPlus when charging should go to the IN but when it's inverting it should use OUT, you obviously can connect both on the BP. It's says clearly in the manual that you shouldn't use chargers on the OUT terminal but how about consumers(aka the inverter mode) on the IN?
The schematic on the Victron site is way too elaborate to translate to my setup. Can I just connect the MultiPlus to the IN of the BP?
Is the standard wiring for the remote switch connector a bridge between the L and H pins?
. . . .
Please, urgent : With 12/1600/70-16 ,MPPt100/50 , shunt and 2 bateries ,what scheme should I follow.Many thanks
I'm currently designing a system for my RV, we plan on having 5 x 315 watt solar panels with 2 x Tesla batteries. The RV already has 50 amp service and a transfer switch (for generator). I'm thinking of a 24/3000 Mulitplus, 250/70 SmartSolar controller and a BMV 712.
I was wondering if I could post the wiring diagram I have made in preparation for an installation in a 2018 Mercedes Sprinter Motorhome conversion with nearly all Victron equipment. I wanted to check before ordering everything that I hadn't gone overboard nor missed anything out and would really appreciate passing it by someone/s here if anybdy had any time/interest?
Hi! I'm adding a house battery system to my pickup truck camper, and I want to confirm the basic schematic before moving forward. I do not want to combine the start & house batteries, and I do not want AC charging available for either battery. I may add an AC inverter at a later date, but that's beyond the scope of the project at this point.
I've left out fuses. switches, and other necessary additions from the diagram at this time.
Please take a look, and thanks for your help.
I am designing a system with x2 lifepo4 138ah 'powerwalls' which I bought without BMS. I am going to keep a close eye on the state of cell balance of the lifepo4's through a separate Battery Capacity Meter plugged into the 4s and balance charge them as necessary.
My system comprises the following - 300w panels, 100/20 victron smart solar mppt, victron multiplus 800/35 inverter charger, 712 battery meter, sterling B2B charger and victron battery protect.
I found the following schematic from a fellow member which Im thinking to use its pretty much the same as my own.
My question is will x1 battery protect be ok (keeping an eye on the discharge) and if so where is the best place to place it? Directly from the battery?
Im a complete newby and if this schematic is good I would use it.
Many thanks for all your help!
