charger

Is there a way to gradually increase or limit charge current on a Multiplus / Cerbo GX to allow Generator to warm up ?

Only presenting FULL charging load when it is warm.

Ideally it would be based on a Cerbo GX temperature input.

Any Help would be much appreciated.

Hi,

The sail drive on my boat suffers from electrolytic corrosion. I just have a Blue power IP 22 charger connected. Do I need a isolation transformer?

I was told the charger itself is a transformer and thus isolated as well so I don't need one. However the corrosion is there?

Many thanks for your opinion.

Hi.

I'm looking for a suitable charger for 4 110AH batteries (Victron BAT412101084) which are in a 24V group (220AH).
I also have a SmartSolar MPPT 75|15 connected to batteries.
The batteries are located in a boat as service batteries.
From time to time the batteries are also charged by a diesel engine via a battery isolator.

Can anyone recommend a suitable Victron charger?

Ich möchte meine vier US2000 Pylontech schonend aufladen (30A reichen) und die Ladeleistung begrenzen.

Aktuell wird je nach SoC mit bis zu 90 Ampere geladen und der Akku ist schon Mittag wieder voll.

Die Einstellung DVCC "Maximum charge current" wird ingnoriert.

Wenn ich die Leistung vom MPPT 250/100 in dem Menü vom Laderegler begrenze funtioniert das allerdings wird dort die komplette Leistung reduziert. Also auch die Überschusseinspeisung entsprechend begrenzt.

Was verwende ich? 3x5 335 Wp Trina, MPPT 250/100, Multiplus II 3000/35 und der Cerbo GX

Hi All,

Could anyone help with this issue please?

I've got 2 smart chargers 1p67 24/12 models. I downloaded the Victron Connect app to connect to them to check the settings but the app would not allow me to connect until I did the firmware updates. The chargers had already been powering on and charging batteries and were working ok, I just wanted to check the settings.

So I followed the prompts and updated the firmware for both chargers through bluetooth.

After this now neither charger will power ON. Both are unresponsive, No led's lighting up or anything. The AC supply is checked and OK, I've isolated them form the batteries and the mains power and reconnected but still no good. Looks like the firmware has killed them??

Thanks

Gerard.

My 100/50 has been working fine for over six months. Recently I noticed through the connect app that the batteries had failed to charge for a few days. Looking at the controller it was not charging even though it was sunny day. The PV voltage was showing at 12.6. I disconnect the solar inputs and measured 19.8 volts coming from the panels. reconnected the input to controller and back working. This has happened twice now and this time controller is saying 6v and I can't get it to charge. Any thoughts?

Just need to know what size circuit breaker to install at both ends..... battery being charged and the battery doing the charging via the DC to DC victron 12v 18a charger ? tks

Hi together,

I have a question concerning using a BatteryProtect (BP) to disconnect the charge source in a Lithium Battery System with VE.bus bms.

In the BP manual Figure 5 illustrates how to connect the BP for charging situation and it states that "uncontrolled reverse current will flow through a Battery Protect if Vout > Vin."

Now I wonder what happens, when the Voltage of the charger (Vin) drops, i.e. Solar charger when there is no sun or any other charging source that is swithched of. Wouldn't then the Voltage of the Battery (Vout) be higher and thus reverse current flow causing danger?

THanks a lot for your comments, I am abit affraid of burning down my RV...

cheers, Daniel

I have set my Multi 12 1600 70 to Charge Only (I have another Victron Inverter doing the inverting).

And when I start the generator in order for the charging to begin the Red alarm light is on and stable (part of the three Green/Yellow/Red lights).

Once in a few minutes, there's a certain kind of "tic" noise, then the green light comes on but nothing happens and the Red alarm light keeps on.

Any ideas or checks I can do?

hello,

I have a phoenix charger but i can't find it on my VE.configure i read that i need the first version of the software to find it. however i can't find any product even with VE.configure 3 and my charger is on.

have you an idea of the problem.

thank.

Hello together,

is it possible to get the values of the Resistors?

my Charger get up to 16,X Volts and like seen on the Picture, there are 3 burned resistors.

i dont know if the resistors are the reason or the impact for the problem so in first step i want to change the burned ones.

Kind regards
Daniel

My PSC IP43 charger is setup to stop charging the LiFePO4 battery when temperature drops below 5°C. It uses data from BMV712 via smart network to get battery temp.

The charger did shut down at 4°C as expected. But it does not restart even after heating the battery compartment up to 8°C.

Is this a bug in the charger firmware or did I miss something?

Hi,

I have a 80 AH Yuasa lead acid CA/CA start/stop battery. In Technical Data Sheet recommended Charge Rate is 4A. Can you help me to choose the correct Blue smart charger and correct settings? I'm between Blue smart 12/7 and 12/10. but I dont know witch one is better for me.

And ,can I use default settings of Blue charger or I shoud change charge rate to 4A according producer recomandation?

I have a Phoenix Multiplus 12/3000/120. This specific model https://www.victronenergy.com/upload/documents/Manual%20-%20MultiPlus%203k%20230V%20Ve.Bus%20enabled%20-%20rev%2000%20-%20EN%20NL.pdf

is there any way to separately control the charger and inverter for a two signal BMS like on the new models?

thanks for any help.

Dear All,

I am new to all this and busy trying to design a simple electric diagram for my camper-van conversion.

I will only be using a 100Ah leisure battery and I was wondering if the DC-DC smart charger 12 / 12 18A would be enough.

I am assuming charging with the 18A would take twice as much time than with the 30A. Correct?
What would be a rough estimation of how much I could charge with say an hour of driving?

Many thanks for your support.
Oliver

I would really like to know if the smart IP43 charger is planned to come out in a 120V version.

I have a smartsolar, BMV, and Raspberry Pi on my RV, and I now need to replace the old shore charger. It looks like my only options are the Skylla-IP44, standard Phoenix, Centaur, or the Multiplus. These are all more charger than I need, not to mention I'm not entirely sure they would work on the Pi.

Thanks!

My IP67 12/25 charger cannot keep a Lithium battery at constant flow/storage voltage. So the battery is permanently discharging and charging again. The problem is varying voltage drop in the chargers wires due to varying DC loads on the boat.

The problem would be solved if the IP67 charger could compensate for voltage drop. Unfortunately sensing battery voltage via VE.smart bluetooth network seems to be currently out of reach, which is disappointing.

My idea to overcome the problem is adding a feature to raise the chargers output voltage as a function of current. On my installation a voltage compensation of 15mV/A would be necessary. It would be great if Victron could add a user configurable setting for compensating voltage drop in mV per A of output current.

Hi folks,

I cant get my battery to charge at more than about 2kW and I cant see why... Obviously missing something?

Small genny, circa 5kW on AC1. AC current limit set to hold that at 19A, circa 4kW, and working. Gen is a recent upgrade, previous unit was smaller.

Putting a 2kW load on results in circa 1.5kW charge whilst running the load, genny a tad over 4kW.

Dynamic limit is off, Weak AC is on - hence the losses I assume.

Bat will not charge above 2kW and typically hovers at 2kW+/- 80W, which looks suspissiously like a limit of some sort.

Easy solar so Multypluss 48/5000/70.

BYD 13,8kW (Temp mainined at 15C min)

Clearly I am missing something and would apriciate somone pointing out what Iam doing wrong or failing to apriciate.

Cheers,

Al

Hi

I have a mostly victron system and looking to replace an ancient RV converter-charger with something to match. Current system:

100ah LifePo4 12v.house bank A

(+2x 210ah FLA. Golf-cart 12v house bank B)

Victron BMV712 +shunt

Victron Smart 100-15 and 75-15 MPPTs

Victron Smart BLUE ip67 12-25a 120vAC charger.

I use an external plug-in honda eu2kw (1800w rated) inverter-generator most of the winter. I need to replace 50a/hour if possible BUT I would really like to take advantage of my 100a RV alternator when driving!

My old converter supplied DC when the old built-in Onan 4kw generator was running or the RV was plugged into shore 120vac and outputted 12v to the lights and fans (etc) and charged the old AGM with about 3-45a depending. I currently use the Honda for everything as there is almost no sunlight here in the winter.

I'd like to set up a simple 3-or-4 way switch via the positive battery cables (?) (I.e. "A-B-Off" or "A-Both-B-Off" as well as the gc2 FLA will be needed as a backup source until I can afford more LifePo4 to replace. The slight issue is 50a is a bit too much for my 210ah GC2 FLA's. Sorta need two different chargers, unless...?

I've considered a 2nd BLUE Ip67 12-25a and a switch to select bank for charging but that doesn't much solve the alternator while driving charging issue...

What do I want to look at to get 50a an hour into my LifePo4's using 120vac? 50a as that keeps the Honda in eco mode snd nice and quiet for the 1.5-2 hours recharging.

Thanks!

I can get a good deal on a Lithium-ION 3S battery, so not a lifepo4 battery.

This battery should be charged at 12.6V.

Rated voltage		11.1V
Max. Continuous Charge Voltage		12.6V

Can i use my current Multiplus 12/3000/120 to charge this battery?

I am charging a LiFePO4 battery on a boat using a BSC IP67 12/25.

Those lithium batteries like to be kept around 50% SOC when not in use. So I created a charging profile with 13.3V bulk and 13.2V float/storage for maintaining 50-60% SOC while permanently connected to shore power at the dock. A few hours before using the boat off-grid I switch to another profile, which charges the battery up to 100% SOC with 14.4V absorption and 13.4V float/storage.

The problem is that the BSC IP67 does not re-bulk after loading another profile. Removing AC for a while does the trick but power needs to be removed for minutes to successfully reset the charging curve.

What I need is a quick and easy way to re-bulk (restart the charging curve) manually.

I recently bought the IP43 Phoenix Charger (because my old Phoenix charger died suddenly). The charger is located near the batteries, but in a different room, so temperature can vary. According to the IP43 manual (p 5, section 4.1) temperature and voltage compensation is optionally available with the Smart Battery Sense. It's also listed as a related product on the website. So I bought the Battery Sense, installed it, created a network. But... no possibility to add my Phoenix Charger. When I did some further reading, I discovered a page about the VE.Smart Networking claiming the IP43 is NOT compatible with this technology (https://www.victronenergy.com/live/victronconnect:ve-smart-networking ).

What is this about? How can I make my IP43 compensate for temp. differences using the Smart Battery sense? Several similar questions were already posted but no answers... Can anyone please help? Thanks!!

Vincent.

Phoenix Smart IP43 Charger no Smart Battery Sense function.

When will the Smart Battery Sense function be added? in the Phoenix Smart IP43 Charger

My Blue Smart IP22 charger (12 V / 30 A - 3 outputs) sometimes trips the automatic fuse of the shore supply when starting up. The fuse is 10 A , B-curve type. No other equipment than the charger is connected at that moment so the charger must be the cause of this. When the charger does not trip the fuse, it functions normally.
What could be the cause ? Is this a known issue ? Any suggestions for a solution ?

When building my boat we increased the size of the battery bank significantly from the base spec (from 324 Ah to 1,000 Ah) and also upgraded to Victron Super Cycle AGM. The charger was upgraded from a 12/30 to a 12/60. The thinking was that shore power is generally limited in amps but usually there is plenty of time. However it seems that we're having trouble getting the bank fully charged on shore power. Now reviewing the Victron spec sheet I see that not reaching full charge may be caused by undersizing the charger presumably because the second stage is on a 4 hour timer. Any thoughts on this? Should I replace the Centaur 12/60 with a 12/100? If so will shore power typically be adequate to power the charger?

Hi, I have a blue smart IP22 charger 12v/30a.

The charger isn't showing any signs of voltage, and it does not charge my battery. When plugged into the mains power, the charger starts up, and I can connect to it via Bluetooth. Just no dc power output.

I've tried a few different cables, no dice.

I tried to take out the fuse by just pulling it, no dice.

I tried to unscrew the screws next to the fuse blade that I thought was holding the fuse in, the screws just spin in its place and not actually coming out. No dice.

What do I do to actually replace the fuse, or know anything else to try?

1. I have a Multiplus 12-2000-80 inverter charger.
   When generator is on, i can use the inverter but can’t turn on the charger.
   - i used to turn on Generator , Turn on inverter to help start AC , then switch back to “charger only”. Now as soon as i switch to charger only, power does not come in anymore from generator. , if i go back to switching to inverter , power comes back on from Generator.
   It worked for about 6 months .
   
   
   
   

Hello! Our client is using our 3P+N DC-AC bidirectional invertor connected to the Critical Load Output of your invertors. The same connection was tried on the following sets. Set #1. "Victron with 3X3 kVA inverters connected in star – 400V+ neutre – 50 Hz" Set #2. "Victron with 3X10 kVA inverters connected in star – 400V+ neutre – 50 Hz" They ask why our invertor does not discharge to your system when VICTRON is in a backup mode (disconnected from the grid). When VICTRON system is connected to the grid, things work Ok. Basically, the customer wants to make VICTRON connected batteries to charge from our invertor when VICRTRON is in the back up mode. I would like to ask if: 1) Critical AC Output of VICRTON invertors are designed to be used for a power injection from "LOAD" to VICTRON in backup mode at all? 2) Are there any assumtions why this scheme would not work with respect to VICTRON embedded logic? Thank you in advance for your support.

I would like to know the answer exactly to the title to my question: is the PCL1-30111S 3000 Watt Inverter Charger compatible with the BT-2 RJ-45 Bluetooth Adapter? I have looked through both device manuals and neither explicitly say they are or not. I would prefer not to purchase the BT-2 adapter only to find it's not compatible. Any help would be greatly appreciated.

I'm having a problem with 2 solar change controllers. I have 2 75/10 and each one is in its own shed. And both stop charging

The batteries are dropping to 11v before I noticed

Both say PV voltage is 21 volts and both go into balk mode but both show 0 amps.

Each one is changing a 12v 100 AH battery

I have to unplug and replug both the PV and battery in order to get it going again.

I would appreciate any help. I have been searching for 2 days for a solution and now I need to ask for help now
