BMV712 - correct settings

I have a 1520Ah battery bank ( 12 volt ) being charged off grid by solar panels. I have just installed the Victron BMV712 battery monitor and a little confused as to what the settings should be set at. The solar controller charges with absorption volatge of 14.4v and float voltage of 13.8v.

So for my setup, should my charged voltage for the BMV settings be set to 14.1v, tail current at 2% for 3 minutes or is that not correct ? Thanks for any advice.

I am considering having a Multiplus 12/1600/70 fitted, however if possible I would like to avoid fitting the Digital Multi Control GX due to space and aesthetics (don't ask).

I have looked in various sites but am unable to confirm if the Cerbo GX will provide all the functionality of the Digital Multi Control GX.

Comments and URL's appreciated.

Victron ip65 12v 10A charging lithium on 0 current

Sorry if this is dumb. I have very little idea what I'm doing.

I have a very new ATLAS 120AH Lithium battery which I assumed was charged when I hooked it up to my existing AGM set up in my van. It worked for 4 days of camping with a combination of the alternator and solar which I was impressed with.

I have since bought the ip65 12v 10a charger and it has brought it back to life, but I assumed it would automatically recognise it as a lithium ion battery. It was in normal mode for hours and successfully charged the battery through bulk and into absorption charge until I realised I should probably change it to li-ion mode. As soon as I did that, it registered 0 current.

The current has been sitting on 0 for a few hours and the voltage is 14.21. Is it doing anything? Will it eventually graduate into float mode? Have I damaged the battery?

Thanks for any help.

Minimum load power to start

Hello everyone,

I would like to know what is the minimum Watts the load needs to be in order to allow the inverter to work.
I'm asking this because a client of mine needs a 24V-1600 Phoenix Smart to power a 9W LED light 24/7 + other loads only a few times a day.
Actually the question arose due to another site where a 7W LED light doesn't turn on if no other load is connected as well.

Victron mppt charger and other charger paralell
Hello people, I have a victron mppt 250/100 charge controller in operation. The problem is that my modules don't fully charge the batteries in winter. So I would like to simulate a power failure depending on the voltage of the batteries and thus start a generator automatically, which then charges the batteries with a charger connected in parallel. Is it technically possible to do this without damaging the mppt charge controller? Does the charge controller recognize the voltage at this moment and switch off? Can a short circuit occur when charging in parallel

easyplus 12 / 1600 / 70 red light + click, no power, no charge

I have a camper setup with

victron easyplus 12 / 1600 / 70

2x battery victron AGM 12-220

after not using the camper for 2 weeks I saw the battery alert was on and the batterypower was only 5,5 V ( external battery monitor, not victron)

when i plug in the 220 V cable the light is red ( not blinking ) and every +- 30 sec I hear a click but nothing happens.

--> batteries not charging ( normally I see the monitor on 14,8V, now stays 5,5V

--> no 220 V measured in the sockets.

I already disconnected all the elements that can use battery-power as i suspect one of the items caused this

I bought the camper with the system so I have no history about the installation. I also found it strange that the batteries didn't charge while driving but that is poblem n°2 :)

Have I made a mistake using a Victron Inverter?

Over the past 4 years I have spent over $30K on solar and battery backup. Unfortunately this has not been painless, and just recently the Victron Multiplus II GX has stopped sending data to the VRM Portal, and the display screen no longer works.

Contacting the installer, tells me to contact Victron Support.
Victron Support tells me to contact my local Victron Dealer.
My local Victron dealer doesn't want to involve himself with a unit he didn't install, saying its a Frankenstein installation (Battery is not on the Victron list).

Is this the Victron way? I'm left with no answers!

Earthing a Victron 500VA inverter

I have just purchased a Victron 500VA inverter and in the instruction manual, it states that the device must be earthed. Could someone who understands the product explain why please?

My application is as follows:

I have a small (2 m X 2m) wooden walled concrete floor remote building in the U.K. with no a.c. mains power. It houses some equipment related to astronomy -

a telescope mount requiring 18V DC supplied by a switch mode PSU

A camera requiring 12v DC supplied by a switch mode PSU

Some microcontroller related control hardware 5V DC - supplied by a switch mode PSU

a 300W , 240V dehumidifier for sucking the moisture out....

Because there's no a.c. mains, I've set up two 12v lead acid batteries in parallel and I charge these via solar panels and an MPPT controller.

The Victron 500VA inverter will be used to provide mains power from the 12V batteries and the SMPS mentioned above are powered by this.

Thanks very much for an explanation of why the Victron must be earthed.

Zeitschaltuhr am Lastausgang

Hallo liebes Team,

Ich habe online einen Laderegler Victron MPPT 75/15 gekauft.

Nun bin ich am erstellen einer Inselanlage mit 2 x 100 Watt SP in Reihe, Victron MPPT 75/15, Batterie-Spannung 24 V, 2 x 12 V Batterien in Reihe.

Am Lastausgang hab ich eine Zeitschaltuhr mit Betriebsspannung 12V/24V. Wenn die Uhr versucht den Schalter zu schließen, zu hören an einem mehrfachen klacken, schaltet sich aber der Lastausgang am Laderegler aus? Manchmal nach ein paar Sekunden oder nach bis zu zwei Minuten und wiederholten versuchen funktioniert es dann. Es sieht aus als würde der Laderegler den Lastausgang einschalten und wenn die Schaltuhr den Stromkreis versucht zu schließen wieder ausschaltet.

Beim Schließen des Stromkreises fahren zwei RaspberryPi hoch und ein Lan-Switch wird eingeschaltet, hängt alles hinter einem Abwärtswandler 12V 24V zu 5V 15A 75W. Strom fließt dann ca. 0.5 – 0.7 A. Ich hab’s jetzt auch ohne Last versucht, ist dasselbe. Zeitschaltuhr direkt an der Batterie funktioniert, also kein Fehler bei der Uhr oder der Verkabelung…

Hab Angst, dass das System sich irgendwann gar nicht einschaltet, oder dass etwas kaputt geht…??

Hab die Last im Moment direkt an der Batterie, aber da verliere ich ja verschiedene Funktionen...

Vielen Dank!

Way to get two 110v outputs from single inverter/converter from battery power?


I am trying to run a Level 2 car charger off my battery bank; I am currently running a Level 1 off my battery bank using the MultiPlus Compact 24v|2000VA|50A which works fine.


I was looking at the Victron Energy Quattro line of Inverter/Converters; I noticed that Victron makes an Inverter/Converter that can output 208+ as long as both the L1 & L2 are plugged in.

When the battery is the only supply voltage it then chops the voltage down to 110-120v. After reviewing this diagram ( and talking to Nothern Arizona Wind & Sun it sounds like I would have to buy an autotransformer in addition to the Quattro.


- Does this sound like the right approach?

- Does Victron have a device that outputs two phases of 110-115v to form 220v or not?

Thank you for any help!

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,

Orion TR12/12-18 NOT isolating the start battery


I have the Orion TR 12/12-18 DC-DC isolated charger fitted between my (euro 6) start battery and my leisure battery but have flattened the start battery twice now when parked up with the fridge running off my leisure battery so have a couple of questions:-

1, Isn't this charger supposed isolate the start battery from the load (leisure battery) when the vehicle is not running, the way a split charge relay does?

2, Even though it's an isolated version, can it share the vehicle body negative or do I need to run a cable between the battery - terminals and charger?

3, Is there a link for a list of faults and fixes somewhere to save people asking similar questions?

4, When setting it up, what is the ideal voltage output the pot should be set, I think it's pre-set to 12.3v which seems low?

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!
