Difference between centaur and Phoenix charger?

Stuck in Panama without a charger, I installed a 12/50 Phoenix charger. My 1050 ah AGM bank can take so much more than 50a. I also want to run my watermaker off my Phoenix 3000w inverter which draws ~90ah. If I’m running the genset while making water I’m putting in 50 ah by way of the charger but drawing 90ah and therefore still pulling a significant amount from the battery( base case scenario 40ah but usually more). If I installed the centaur 12/100 I would be putting in 100ah into battery with genset on. Then I’d meet my power needs of 90 ah to run my watermaker plus a little extra to put in the battery bank (all hypothetical based on efficiency and other items drawing but you get the idea). Question. Does my logic make sense? What is the difference between the Centaur 12/100 and the Phoenix 12/50 besides charging amps?

Question on BMV and Battery Capacity Setting

Hello everybody, I wish you all well!

I have a question I hope you can help me get answered.


Suppose I have a 100Ah battery and a BMV Battery Monitor.

Suppose I want to keep this 100Ah battery at a minimum charge of 80% (for reasons of well being of the battery).

To make this clear to me, Suppose (again, sorry) I want the BMV's SoC to tell me 0% when it has in fact only reached 80% ...


2 questions:

Would I accomplish this by setting the battery capacity (of my 100Ah battery) to 20Ah?

Would this ("faulty" setting) create havoc in any way (I mean would this stop my batteries from properly charging, cause it to self destruct or cause any other devastating activity?


Thanks for your thoughts, I'm trying to understand how to set up this thing to my personnel liking.

SOC not working on Multiplus 2 48/5000/70

I have just setup my new Multiplus. The SOC just reads NA. Looking at the battery monitor in the remote console it says automatic. I have tried changing that to Multiplus as well as it still says N/A.

As its brand new (only been running a few hours does it take time to come up with a reading? I dont have a BMV or anything just the Multiplus 2.

ArgoFET unused output ok?

I have twin Cummins 6CTA 8.3 motors with 150A alternators. I purchased 2 ArgoFET battery isolators to recharge the house bank from the alternators. I purchased the 1 input, 3 output battery isolators (starboard engine starting bank, port engine starting bank, house bank) however I think I only needed the 1 input, 2 output battery isolator.

It seems simpler to have the starboard alternator recharge the starboard starting battery and the house battery, and the port alternator recharge the port starting battery and house.


Can I leave an output on the battery isolator unused with a rubber cap on it? Or are they designed to require being wired to a battery?

Victron LiFePO4 cell voltage not balancing

Hi,


I have 6 batteries in a bank comprised of Victron 300amp LiFePO4 batteries. Two of the batteries have voltage balance issues. The problem shows up 2 ways:

1 - When charging reaches Absorption one cell is behind the others. The battery is at 14.2v but the cells are at 3.62, 3.62, 3.61, and 3.35. I have this same condition on another better. One is Cell 1 the other is Cell 4.

2 - When charging reaches 98% (per the CCGX display) the troubled cell is running very fast to 3.74v while the other cells are at 3.40, 3.37, and 3.37. The BMS does its job and stops charging. The voltage drops down to 3.6 then the charger kicks back on and the cell quickly rises to 3.74 and charging cuts out again. This repeats until the battery reaches 14.2 and goes into absorption.


I have the following components and firmware:

* Lynx Shunt 1000A VE.Can - v1.08

* SmartSolar Charger MPPT 150/85 rev2 - v1.53

* Quattro 12/5000/220-2x75 - v474 Product ID 2633

* CCGX - v2.53

* VE.Bus BMS


Per the advice of the Victron certified installer I have deeply discharged the battery bank to 30% SOC per the CCGX display dropping voltage to 12.8v while under some load and charged it back to 14.2v and absorption. The cells do not appear to be coming up in line with the rest of the cells in the battery.


Any ideas on how to resolve this issue?


Thanks

Replacing a CBE CB 516 with a IP22

I am replacing a defunct CBE CB516 charger in my motorhome with a new IP22 12/15(1) charger. The old charger has a small single core wire on a separate terminal as a NET feed. It is labelled +12v . It takes a signal to the motorhome control panel to show that the charger is 240v powered on. As the IP22 only has one +12v terminal ,would it be ok for me to put the small 'net' cable into the same + terminal? Worried about damaging the new charger? Also if the 240v is off would this way of connecting always show it as powered on?

Voltage at input isolator argofet alternator is off

When every load is off on the boat, the input at the battery isolator argofet reads 4.4 volts. If I disconnect the house output, the voltage drops at the input to 2.2 volts. But, not, the output 2 terminal will also read 2.2. volts.


It seems that my outputs are actually pushing voltage through the isolator to the rest of the terminals.


Is this normal?

Limit SOC for longer LiFePO lifetime

Is it possible in some way to limit the maximum SOC of my Pylontech US2000 Batteries wit the Cerbo GX?
The reason for my idea is to longer the lifetime and healt of my batteries by not charging them to 100% in the summer, because I have a very large battery storage, more than 20kWh, and thatswhy it would be enough to charge them to 80% at least.

Do I need a DC/DC charge when using a BMS12/200 to charge from an alternator

This is my first build and it is going into a commercial camper.

I am planning on using a 200Amp/h Smart Battery, which states it needs a BMS to work.

The BMS 12/200 states that it is a dedicated product for this application, where connected to an alternator of a boat/ vehicle.
Do I connect the BMS directly to the start battery? or will it require a DC/DC charger to moderate the flow?

As a supplementary question, do I also route the MPPT from solar and the mains charger through the BMS.

How many amps on float mode for agm battery?

Hi,


How many amps should Orion TR 12/12 30 be pushing into Victron AGM battery on float charge?

When float charge starts I am getting 5-6 amps in for the first 30 minutes and then slowly down to 2.5 amps but that would take an hour or so,

Would that mean the battery is still getting charge for the first 30 minutes?

Color Control GX stopped working, no SOC on my EasySolar 24/3000

Hi all,Recently my Color Control GX unit has stopped working giving any readings about the SOC and energy leves used on my system.

I can still use the mobile app on my phone and there everything seems to be fine.

All system is updated with the current latest software and firmware patches.
Tried flashing the CCGX unit by inserting a MicroSD card on the slot on the bottom to no avail.

I suspect the data connection of the CCGX unit and or the battery monitor cable have a defect.
Since on the mobile app I can get readings via bluetooth.

Any ideas where to look for? Do I need to open up the Easy solar and check for bad connections? Which ones? Any specific dipswitch settings I might have overlooked?

When will Victron start to supply a AC to DC regulator for windturbines?

you can use the DC to DC charger with a windturbine. I connected my 400W AC wind turbine to a rectifier. The output I connected to a spare 200Ah battery. From there I took the input to the DC to DC charger and connected the charger’s output to my 1000Ah AGM battery bank. I switched of engine detection set the aborption to 14,1V and the float to 13,5V. Input switch off at 10,5V restart at 11,0V It works perfect. My question. When will Victron start to supply a AC to DC regulator for windturbines?

Centaur temperature sensor

Hi to all from a newbie on the community board.

I wonder if anyone has any knowledge regarding the temperature sensor on a Centaur 12/40 charger which is fitted to a Dutch barge I have purchased? As soon as I connect 230V to the charger the fans (both) start to run and then run continuously. The charger is connected to 2 battery banks both 12v (one battery @230Ah and a bank of 3 @230Ah total 960Ah). I appreciate that the charger is well below that recommended for a bank of this size but budgetary constraints mean that, for the moment at least, I have what I have.

I assume that the problem is with the temperature sensor, but this is just an assumption. Trawling the internet has offered no solution so far.

I have checked throughout the charger for hotspots but none are apparent with the largest temperature differential being about 2C above ambient level. The batteries all appear to be charging fine and are all less than 10 months olds.

I have tried emailing Victron directly but have received no response.

Any thoughts on how to proceed would be gratefully received.

Many thanks in advance.

Orion Tr isolated charger- remote cable function


I'm trying to understand On/Off options for the charger before purchasing. I couldn't find much information about the choices that you have on the victron app. However, I do understand there is a choice between "converter" and "charger" mode.

*I will be using it on my boat between the house bank(charged by alternator and an AC/DC charger) and a seperate Bow-thruster bank.

Question 1: are "converter" and "charger" the only options for triggering on the unit?

Question 2: does this choice effect anything else besides the activation and deactivation of the unit? For example, I would like to choose the "converter" option and leave the remote terminals permanently bridged. This way the unit will only kick in while the alternator is working. However, I will be using the unit to charge a battery bank. Is the "converter" option ideal for accurately charging batteries?

Thanks to all in advance!

Victron Blue Smart 12V 30A - easy exchange possible with present recharger?

I'd like to mount two gel batteries instead of the ordinary one that was delivered with the car - and so I need to replace the battery recharger with a better one. I'd like to integrate a Victron Blue Smart IP22 12V 30A recharger. The old CBE device is responsible for a) recharging the battery and b) supporting 12V DC power to the car when AC230V is plugged in. But it's a really simple box with only one DC outlet... can I easily replace it with that Victron device?

Phoenix Smart IP43 Charge, VenusOS and Lithium

I have been searching the internet to understand how the IP43 Smart Charge integrates into a VenusOS and Lithium based system. There seems to be a lack of information, or I'm looking in the wrong place ;)

Does anyone know if the VenusOS will via the VE.Direct port turn the charge on and off based on the BMS state information, as it does for the MPPT Smart Solar?

I don't believe that it is included in part of the DVCC Maximum Charge current yet.

Dose anyone know if the VenusOS can supply voltage sense information, through DVCC.

I don't really want to just buy a unit to test and find these things do not yet work. Anyone have any ideas on how well the VenusOS and Phoenix Smart IP43 Charge work over VE.Direct?

App says Orion Smart charging is disabled, current meter says otherwise.

My Orion Smart 12v/12v-18a charger is set up for LiFePo4 batteries. The iPhone app says charging is disabled, but my clamp-on current meter shows 10-15 amps. If I flip the remote switch, the app reports that immediately so it's not a Bluetooth connection issue. I've verified that the current meter is working, and I've power-cycled everything (including the phone).

If I turn off charging via the remote switch, I see the current go down to zero. So that's working at least.

Thoughts? Ideas?

Using 200AH LFP bank to charge my “dead” FLA starter battery

This is a hypothetical situation but it’s winter here and the boat’s in storage, so... Here I am, sitting on the boat, at anchor. No shore power, but the 370W PV is keeping the LFP bank happy via the Victron 100/30 MPPT. I control both the starter/engine bank (FLA) and the house bank (2 100AH Battle Borns in parallel) with a 1-2-All-Off switch. BUT, I forgot to switch the circuit to “2” (house bank/LFPs) when I anchored, and the loads drained my FLA engine battery. The Orion 12/12-30 is off because the engine is off. Can I switch to “ALL” to allow the LFPs to push amps into the FLA battery to give it enough juice to start the engine? Yes, I’d measure the voltage at the FLA battery to be sure I had enough power to start the engine without compromising the LFP bank. Advice and suggestions, please?

Blue Smart IP22 Charger: No characteristic absorption curve

Hello,


I need your help. I have a problem with my Blue Smart IP22 Charger 12/15.


The charger should charge a lithium battery (4 x Winston cells). I have set the absorption voltage to 14.2 Volt. The highest cell is at 3,568V. So there is no OVP situation.


In the absorption phase the current should drops at constant voltage: But after about five minutes, the current and voltage jump wildly up and down in the absorption phase.

What is the reason for this behavior and why doesn't the current simply drop further towards 0?

Thank you very much.

Victron MultiPlus C12/2000/80-30 stops loading

Hello Victron Community

I'm operating a Victron MultiPlus C12/2000/80-30 in my campervan.

It's a new device which was installed 6 weeks ago.

My use case is, that I usually park the van in a garage on Sunday evenings, plug the van into the normal grid, the charger starts working in bulk mode and charges the battery. All as it should be.


Now comes Saturday morning, I return to the van after a working week has passed, and the battery capacity (240Ah Li) is on 75% and the charger does not charge the battery any more.

Only when I swich the charger off and on again on the remote control panel, the MultiPlus will start charging again.

I repeated this several weeks now and the pattern is stable. It's always the same percentage battery load left an the charger does not charge any longer.

I suspect that the charger loads the battery just fine up to 100% (which I have seen at an intermediate control visit) and then switches itself off after some time but always at the same time after the battery was fully charged - hence the stable 75% value of battery load when I come back to the van.

Also, I think that it must be the MultiPlus itself that consumes the 25% battery load in the meantime as there are no other devices running except from the display of the Battery monitor and the display of the heating system.

Why does the MultiPlus stop charging the battery after some time and why does it consume energy?

I'd be extremely grateful for any hints!

Many thanks, Markus
