Or is there and where can I find them? Id go with the 48 volt version but that makes it difficult to charge the house bank off the engines as the dc/dc chargers are all 12/12, 12/24, 24/12...

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.

Where can I find the requirements for becoming an authorised Victron installer?

Can seems to find anything on the Victron Energy website.

Thank you!

Hi,

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.

thanks

Ive found chinese copys of a bmv and charge controllers. i wonder how safe the cheaper items are.

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.

Thanks

I have my BMV 712 hooked up and it is showing 13.04 volts but the amps, watts, and AH are all displaying 0.00. The %says 100 and inf hours. Any thoughts?

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

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.

Hello,

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.

Best regards, Steve Fairless

I woke this moring to find the Overload, low battery, high temp lights on. Plus the float light is also on. None of the faults are taking place now. Its possible battery was low in the night. I have disconnected all inputs and outputs to see if it will reset, but it has not. Does nybody have ideas on what to do about it please?

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.

Hi, All

Just a quick question, as room constraint. Can I mount victron DC power in and DC Distributor up-side -down. Which is cable holes up rather through bottom.

Thanks

Hi all, does any body know if Victron have made stencils for Visio for their Victron Products?

Or if any body else made it and made it free to use.

It makes lite so much easier when making my schematics.

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.

Thanks and best regards, Bernd

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:

[image]

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

My consumers in 12 V are:

[image]

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,

Wendy

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!

LG lottebounty

Hello,

I've got a Victron Blue Power Charger 12/15, the older model without bluetooth.

I have a 150Ah Victron battery as house battery for all equipment. I also got a 60Ah starter battery attached to my outboard. Between the two I installed a Victron Cyrix-ct 12/24V-120A.

Now when I am at the marina, can I use my charger to charge the batteries? Is it powerful enough for this set-up? Can I leave this charging all the time? I have got a remote power-switch installed so I could also just charge the day before when I want to take my boat out a day..

Hope to hear you soon,

Kindest regards, Marcel

My multiplus compact is going straight to passthrough instead of going to charge mode. The batteries are not fully charged, so I think it should go to bulk. If I reset it,it does goes to bulk.

I'm testing my new Multiplus 12 | 3000 | 120 | 50 inverter and noticed it shuts off and kicks back on after a few seconds. It does this quite frequently. Here are the conditions:

Inverter is connected to 600AH lithium batteris and in inverter mode. the load is about 1700W. The battery monitor shows battery voltage is 13.2V and the current is 128A. Before the inverter shuts off, there was no low battery indicator on and no other warning LED was flicking or on.

Is there a log somewhere I can retrieve from the unit? I have the MK3-USB cable and am able to use the VEConfigure.

The Venus has a 5VDC Output - Does the MultiPlus II GX have anything similar? I cannot see but I am hoping I've missed something.

My eyes nearly popped out of my head.

I was looking for solutions to connecting more than one MPPT to a MultiPlus II GX and thought, "Could I use a VE.Can port with a VE.Direct to VE.Can adapter?".

Sure enough, there is such a thing "VE.Direct to VE.Can interface" (ASS030520410) but it is about the same price as the MPPT I want to connect about 300EUR.

Now, I have since learned that you cannot use VE.Can on the MultiPlus II GX for MPPTs but I am still interested in why the VE.Direct to VE.Can interface is so expensive?

We have a sailboat with 4 * 200 ah 12v - packs of 2 batteries for 24 V.

Everything is Victron - Quattro 8000 BMS VE and monitor etc.

The batteries made the BMS kick in and the Quattro showed (low battery) - and wound not charge.

We called in for help which resulted in loosing the setup and that we had to have the communications card on the Quattro changed and now the blue panel also.. We can no longer access the menus in the panel and we don't have access to the Quattro.

As soon as we use the hydraulics an alarm goes off and we can't see how much power is left on the 2 working batteries ? So we are running the Panda generator all the time.

BUT the Quattro will now only run on 1 pack of 2 batteries. When we connect the other pack the red light comes on on the BMS. With a Victron smart 25 amp 12v charger we measure 14.4 v separately on the 1 pack of batteries that results in a red led and aprox. 13.7 v on the other pair.

What could be wrong? The batteries are from 2016 LiFePO4 . Can a battery be reset so the BMS does not create a red led?

Thank you Tor

Hey there, since the dc inverter draws power directly from the battery (not through the charge controller) is the battery protect the way to go so that the battery is not completely drained? i use a 1000W inverter (~83 Amps draw), with 2000W peak consumption, so i suppose the 100A model would be suitable. i am not talking about a starter battery on a vehicle but an off-grid system. cheers

Brand new 2 battery Victron solar system used to run Oloid 400. Started right up and ran for 2days and then just quit- red light comes on 10R-05-4003 Controller. Ran diagnostics and indication is either overcharge or BMS- is not overcharge as each cell is 3.35. Is there a reset, a fuse, or do I need to replace the controller or is it something else

I have a victron 100/30 regulator. My two roof panels supply 48v into the regulator.

I want to add in portable panels when the roof panels are in the shade, but these will be 24v input into the same regulator.

Any foreseeable issues with this setup?

Hello,

Looking to do the following on a cheap budget for a farm bound friend who is currently burning dinosaurs (geny) at a rate that makes me cringe.

120-130A/hr dc usage at 12V a day

so he likes 12v because he understands it so being a remote farm i want to keep it 12v nominal at the batts.

I can get 175w victron 12v panels locally too was going to wire 3 in parallel down to a dc breaker then to solar regulator. (will make leads esy to follow for him and ill use colour shrink on pv cables so he can easily identify the pos/neg of each panel should he need to remove one as result of damage.

so i was going for

3 x 175 victron mono panels Reference No. SPM041751200

bluesolar PWM yes PWM (remember cheap) sub tropical location too has display and charge his phone via usb thus (Saving $200 over the MPPT this covered the 3rd panel) I figured 525watts via PWM would outperform 350watts via MPPT.

800w victron inverter

360 a/h battery bank

12/30 victron charger

I know its only 3 days carry over only but he must run a stock pump for a few hrs every few days so ive added a victron 12/30 battery charger so when hes burning dinosaurs he can top up bank if required .

so thats back ground for you all

now to my question ... the PWM says 36 cell panels are best used but the 12v victron panels are 72 cell even though they are 12 v ??? are these still suitable ??

Am i silly to use the PWM ..after reading the white paper and everything else I could find it seems that 12v nominal systems are the go right up the 30A limit which will be right on for him. and as said the $200 saved has paid for the additional 175 watts.

cable runs all calculated for less than 3% voltage loss more like 1-1.5% as everything is pretty close together.

all fusing and breakers are dc rated so all covered on the saftey front.

Just that lingering 36 v 72 cell 12v panel question.

I could buy 2nd hand 24v pv panels and the MPPT but after many hre drive to set this up remote Id rather give him good new gear from victron and ensure I he has no issues.

thoughts

Future expansion is not and going to happen .... and 240v ac usage will always be kept to bare minium hence the smaller inverter.

Thanks for reading

Hallo

Have this setup: victron mppt 75/15 + blu. and 3 x 80 EXIDE ER350 DUAL battery. But can not find data sheet on these batteries. These are wet lead batteries. Can you help with settings? Thank you.

Good day all,

I would like to inquire the required AC Out 1 protection needed to protect a grid connected Victron 5kVA unit.

Thanks

Hi,

I have following configuration:

3 Victron quattro 48/10000/140 (3 phase system)

2 BYD Box 13.8

1 SMA Sunny Tripower STP 8000TL-20 (existing)

2 SMA Sunny Tripower STP 10000Tl-20 (new)

It is a Off Grid System with a generator for emergency situations.

- Victron with BYD works, no problem (victron provide a manual for that)

- SMA STP 8000 works with victron, no problem (was a existing installation)

Question:

Which parameter i have to program at the two SMA STP10000 that they stop working when the battery is full ?

Thanks in advance for every input !

BR Daniel
