Project: New loading infrastructure


I am in the process of updating my charging and monitoring configuration.

I have created the attached overview.

I want to monitor the charging behaviour of the batteries and the solar panels. I would like to be informed if something is wrong and especially if the shore connection fails.

I would also like the charging of the batteries to stop when they are fully charged.

The question in the round:

Is my overview so correct?

Can I do it this way?

Thank you in advance for the feedback.

How to set inverter and charger current with mk2 bus

Hello, i want to set the Victron Multiplus 24/1600/50 inverter or charger current with the mk3 usb interface. i read the VE.MK2 protocoll but it is not clear for me how to do.

i tryed to create a 'S' command, but it do not work.

if i switch the inverter with the switch on the inverter to inverter mode it starts to invert full power.

i do not know why?

i tryed the command

If anyone could tell me what is the name of the plug/connector type model I would be much happier person :-)

I did check documentation also looked at different connector types and could not find a simple thing - what is the connector type model. I also can't find Victron cable that is meant for this port.

In welcher Umgebung ist der Multiplus II 3 KVA einsetzbar?

Ich plane eine Anlage mit einem Laderegler und Multi plus. Dabei mache ich mir auch Gedanken über den Einbauort und die klimatischen Bedingungen. Beim Laderegler scheint das unkritisch zu. Also draußen, regengeschützt. Wie sieht es aber mit dem Multi plus aus? Ist der laut? darf der zum Beispiel in einem Schuppen sein? Hat der eine Lüfter im Gehäuse usw. Wo habt ihr die Komponenten verbaut? Also Laderegler, Batterie, Wandler etc..

Hoping for opinions on full Victron RV system plan

Dear all,

as I am new with all Victron components and quite francly electrics in general, I would really appreciate some opinions on my system plan. I have already put a lot of effort into this and read lots of articles and info but in the end every system is individual in itself and I am by far no expert yet.

I am planning to install all this into a bus that I am currently converting into an RV in Germany. I'm saying that to make clear that there is no current "house electricity" in the bus except cables throughout the walls to all appliances and outputs. For all 12V wiring I ran positive AND negative wires, so I guess the Orion DCDC converter might be an unneeded add-on in my case.

I don't really have many specific questions anymore. I was more hoping for someone with experience in Victron equipment to approve/or help improve my plan.

The only specific questions I am left with concerns the 4A trickle charge output of the Multiplus. Is it okay to just hook this up to my start battery positiv or do I need to be concerned about overcharging this battery once full?

I thank everyone who might get involved and look forward to any input you all might have.

MultiPlus Compact - second battery connection - charge function?


I have a Multiple Compact 800 24v with the secondary output connected to start battery to trickle charge when parked up.

Question - does the 800 only power the second battery output when AC is connected or does it also take power from the primary connection (leisure batteries) to cross charge the secondary battery when the AC is off?

Reason for asking is that it seems to work the second way as I see current flowing to the secondary connection even with AC off!

Victron app incorrectly indicating low panel voltage and charger not charging.

My 100/50 controller has been working flawlessly. One day, it failed to charge, even though there was plenty of sun and my batteries needed it. The app indicated that the controller status was OFF and that the panel voltage was lower than the battery level, which didn't make sense. I removed the panel wires at the controller and saw that the panels were providing over 20 volts, and not the 12+ volts that the app indicated. I unplugged the panels and batteries from the controller, waited, then reconnected everything. The controller immediately started to work properly, charging my batteries, and worked fine for a couple of weeks...until today.

Today, the app indicated the earlier problem. My batteries were in the neighborhood of 12.50 volts, and the app indicated that the panels were only providing something like 12.47 volts, even though it was very sunny. I again disconnected the panel input wire right at the controller and saw that the panels were actually providing well over 20 volts. I again disconnected both the panel input and batteries from the controller, waited, and reconnected everything, however the controller still won't charge and the app is indicating that the panel voltage is again just under the battery voltage. Thoughts?

On the VICTRON SMARTSOLAR MPPT 250/70-MC4, the blue light next to "Bulk" flashes slowly.

In the Ve connect app, PV Solar shows 0.00. But measured, from the solar panels come in 156V, which is not stored in the battery.

On the CCGX, the MPPT state is off.

What could be the reason why MPPT doesn't turn on?

Product request - Smart BMS CL 24/100

Lately we have many requests for installing big RVs with big 24V alternators (100A or more) and also more than 400Ah or more of lithium batteries.

With lithium batteries you should use a DCDC-charger but if you want to (or have to) charge the batteries from the alternator as fast as possible you have to install 2, 3 or more Orion-TR Smart or use 2 BuckBoost 100A (which is way to expensive).

So it would be great to have an easy way to limit the current like it is possible in 12V vehicles with the Smart BMS CL 12/100.

Charging start battery from leisure bank

I have a 200 ah LiFePO4 leisure bank on my boat and a FLA start battery. I would like to charge the start battery from the leisure battery. I would like to be able to do this manually and without any reliance on external charging such as mppt, alternator, shore power etc. running. Think of an AC - DC charger where you turn on the charger and it charges the battery. Is there a product that will do this? The Orion-Tr Smart DC-DC charger non-isolated was suggested But I can’t find any documentation as to how it would fit this scenario.

Victron MultiPlus 12/2000 Not Charging

Hello All.

Occasional reader; first time with a question.

We have MultiPlus 12/2000 and Smart BMV-712 controller installed in our sailboat, which has been connected to 240VAC/50amp shore power for the past 2 weeks. Our house batteries 2 new RELiON LiFePO4 batteries with 600 amp hours total capacity. We also have 4 Solbian solar panels linked in via their own Victron MPPT controllers

The problem is the batteries are not staying fully charged by shore power. During the nights, when solar isn’t making a contribution, our batteries drop down to 75-85% State of Charge, and they are discharging when I check the system in the morning before the solar panels kick in.

When I look at the MultiPlus first thing in the morning, the amber light is flashing indicating “The AC input voltage is switched through and the charger operated in float mode.” If I reset the MultiPlus by either turning it off for a few minutes or going from Inverter mode to Charger only then back to Inverter, the system starts charging and the amber light goes solid indicating “The AC voltage is switched through and the charger operates in bulk or absorption mode.” The batteries will then charge to 100%

If I do nothing, the solar will kick in when the sun gets high enough and the batteries will charge to 100%.

Please help me understand what’s going on here. Thank you.

Help with setting victory 712 bluetooth + Rocket 6v 210ah series and parallel



Just got victron 712 and base on my understanding my class A have rocket in series then in parallel

I have two in series that gets them to 12 volts but that cuts your amps in half. Then those sets are in parallel which keeps the volts at 12 and doubles your AH rating. They start at 210 AH. So that means each battery set can produce 105 AH. Sooo i have 210 AH total.

what do i need to do in setting and configuration? I dont have solar or anything.

Are some victronenergy and Epever product the same??

good morning, I have a doubt.

I have seen that the victronenergy pwm bluesolar pro and bluesolar duo controllers are IDENTICAL to the pwm Epever Landstar B and Ep series duo controllers.

Even the "solar station monitor" PC control software is exactly the same.

The victronenergy remote monitor is also identical to the Mt50 Epever.

As well as all settings and manuals for these products are identical.

I would like to know if the product is from victronenergy and has been copied with or without permission from Epever, or vice versa.

Or there is an external manufacturer who supplies the products to victronenergy and Epever, and they place their own brand.

Why does my inverter trip the breaker when first connecting?

I have installed a Victron 3000/120/12/50 into a new van build and when I have it plugged into a 20 amp shore power and have 3-4 amps (in breaker panel) already turned on with breaker; I turn on the inverter and it trips always. Now the inverter shows low battery when it trips......why when the batteries are full and the shore power is on. If I shut the two breakers off and turn on the inverter first before I flip a couple low amperage breakers the inverter will not kick off. Any ideas. Thx

Victron multiplus 12/2000

I have a victron multiplus 12/2000/80 inverter charger fitted to my narrowboat.

every so often, roughly once a day, it switches itself off, all the 240 sockets go off and around 10 seconds later it switches itself back on and all is well.

there are no warning lights on the panel, the switch is set to ’charger only’ and I’m on 240 mains power via a land line, none of the other narrow boats are having this kind of problem

i have been told this is very common and just a safety features of this unit as it’s checking it’s systems, charging etc.

my question is of course IS it normal? Or is there an underlying problem?

any help/advise is appreciate.

Multiplus 12/1200 not working


We installed a Multiplus Compact 12/1200 inverter and 3 x Victron Lithium 12.8/90Ah batteries for our customer Mr Rowe in 2016, and they have worked well since then, until recently when the output feed from the Multplus was connected to a large load by another contractor by mistake. The system tripped the overload on the Multiplus, but after that has been reset the system will stll not charge correctly. Could it be damaged internally, and what checks can we perform, without invalidating the warranty? The system has online monitoring.

Can you use Victron’s products to add 48-V battery backup to an existing 220V, 50Hz, 3-phase, grid tie SolarEdge installation, and provide energy to the batteries when the grid fails?

I tried finding a suitable solution for this problem; however, I was unable to find one.

The problem presents itself when:

1- you have a 3-phase, 50Hz, electrical SolarEdge installation with a SE inverter and optimizers.

2- you want to add a 48-V battery storage only to one phase.

3- you want the existing PV array to feed the battery in case of grid failure.

4- you do NOT want to add additional solar panels or generators.

5- the capacity of the existing SE inverter is larger than Victron’s inverters.

It is too difficult or too expensive or both to solve this problem with Victron products.

I found a SE note suggesting solutions for this problem using a second inverter ONLY from SE to do DC coupling or AC coupling, or to replace the existing SE inverter with a newer inverter from SE compatible with optimizers and able to store energy in a 48-V battery.

However, these solutions, sadly, will work only with LG or SE battery systems. This limits tremendously the types of battery chemistries and options of battery manufacturers compatible with the newer SE inverter.

Victron 75/15 7s LiPo 18650 settings

Hello all,

I have a SmartSolar mppt 75/15 charge controller and I'm wondering how the settings for a 7s19p Lipo 18650 Pack should be. The battery pack is made with Samsung INR18650-35E cells.

I try to made the settings to get a long battery life. So charge upt to 4V per cell? Discarge down to 3.5V per cell? Made this sense?

Currently I made the settings as shown in the picture. So, if someone could say "That's fine" or "Made this setting differen" then this would be fine.

Help defining specs charger/inverter and battery protect CAMPERVAN

Hi all! :-)

I am a young an enthousiast girl buzy with a camperitzation of a van (not sure how far I will get but I'll try!) and I saw and read a lot of information, but I have some doubts about which criteria to follow when choosing Victron equipment. Hopefully someone can help me! My apologies upfront if I'm asking stupid questions :(

My system will have:

- 2x320W solar panels

- 2x170 Ah 12 V batteries (link 1 or link 2, to be decided) --> are these ok for the application?

- 1x Relay RL-180/200 12 V to connect to the alternator

- 1x SmartSolar charge controller 100/30 (because max current both panels is 21 A)

But I am not able to define what are the specs that I need for the:

- Multiplus inverter/charger from Victron:

First question is, do I want a module that does alltogether or shall I buy separate components? Second question: which is the power that I need for the charger and inverter side?

My consumers in 230 V are:


Total A/day = 23,73; Total W/day = 5458

My consumers in 12 V are:


Total A/day = 102,88; Total W/day = 1234,6

Third question is: I want to install an outer power take off to connect to the camping 230 V socket and charge/use the 230V consumers with the electricity of the camping mains. If I would connect the vehicle to the camping socket, will the multiplus inverter/charger charge the batteries and allow me to use my 230 V consumers at the same time? I want to avoid the situation of connecting to the camping grid, batteries not full and using 230 V consumers and not having enough power, since with a 10 A socket from the camping, I can only consume 2300 W (3680 W max with 16 A). Like: I plug to the camping socket and I plug my hairdryer, does the inverter charge at the same time the auxiliary batteries? If so, with a 12/1600/70 model and a 1000 W hair dryer, I could not connect many more things since the inverter can deliver max 1300 W!

Is the 12/1600/70 indicating the max charging current of the battery? What is the maximum charging current of the batteries? 170 A?

Also not able to define which:

- battery smart protect: fourth question: which of these 65A/100A/220A ? or another?

Sorry for my lengthy email, but I am new in this field. Every help is very appreaciated!

Many thanks in advance,

Lastausgang Victron 75/15 schält ab

Hallo zusammen,

ich habe eine dringende Frage: Wir haben in unserem Van eine 120AH Batterie verbaut, die via Solarpanel geladen wird und mit einem victron 75/15 laderegler verbunden ist. Obwohl die Batterie momentan bei schönem Wetter tagsüber geladen wird, schält der Laderegler nachts andauernd unsere (an Lastausgang angeschlossene) Kühlbox ab. Diese verbraucht ca 4A. Die Batteriespannung lag gestern abend bei fast 12V, momentan zeigt die app 10,27 V an. Auch wenn man in den App Einstellungen den Lastausgang auf "immer an" setzt, schält er irgendwann aus. Kann uns da jemand weiterhelfen? Die Batterie hat doch so viel Power und wird dazu noch tagsüber mit Solar geladen, da sollte sie die Kühlbox ohne Probleme über Nacht laden können?Finden wir nur nicht die passenden Einstellungen??

Vielen Dank für eure Hilfe!
