Blue Smart IP22 charger trips automatic fuse

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 ?

which charger? World Voltage, Cerbo/BMS, higher amperage?

I need help selecting a Victron 12V charger that

  1. Can handle 120V and 230V power
  2. Can connect to a Cerbo and honor stop charge commands from the Cerbo (which in turn is listening to REC Victron Compatible BMS)
  3. I need relatively high amperage charging. 100a would be ideal.

Are there any devices that would work? It seems the Centaur doesn't communicate with Cerbo, and isn't programmable.

BTW, my absolute fantasy product is an inverter/charger that can plug into any shore voltage, but puts out only 230V. Sort of an transformer/inverter/charger.


I'm on a boat that uses shore power all over the world, so I need to be able to plug in to USA 120V and 230V everywhere else. I use that to charge my batteries, and use a a separate inverter using the batteries to provide AC house power to the boat. I currently have a Mastervolt Chargemaster 12-100 that handles any voltage. That works great, but now I'm upgrading to LiFePo4 batteries, and the Mastervolt doesn't have Lithium profiles, doesn't seem (???) to be programmable. It also will not connect to the Cerbo or Bms, so I can't send stop charge commands.

How to or not properly connect a charger?

I'm curious if there's a critical protocol for connecting or disconnecting a charge controller. It's my assumption it's ok to tie in live panels so long as a battery is connected & to disconnect any live panels before removing the batteries. Would that be right? And is it a bad move to connect live panels with no battery connected? Or suppose a battery breaker trips & disconnects the battery from the charger with live panel power, would that fry a charger? I'd like to think Victron has these scenario's covered for protection against such things but I had 2 chargers fail within a couple of days of each other & not sure if 1 of those was the cause.

Alimenter un bloc électrique EBL119 dans un CC

Bonjour à toutes et tous,

J’ai besoin de votre avis sur l’alimentation en 12V d’un EBL 119. EBL est un bloc électrique qui équipe la plupart des Camping-Cars.

Mon intention est de retirer complètement la batterie de service équipée de base (AGM) et sa connexion à l’EBL et de m’équiper en Lithium 2x 200Ah.

L’EBL n’étant pas conçu pour le Lithium, je m’équipe totalement différemment et le tout en Victron.

Mais je souhaite quand même garder l’EBL qui gère les alimentations 12V du CC, pompe, chauffage,etc…

D’où ma question :

Est-il correct d’alimenter l’EBL (sans batterie de service donc) par son entrée chargeur +/- qui autorise une alimentation en 18A et câblé en 16mm2, ceci serait possible grâce au Chargeur Orion-Tr Smart isolé 12/12-18 depuis le parc Lithium ?

Ou est-ce un autre chargeur ?

Si ceci est correct, est-il judicieux d’installer un BatteryProtect pour éviter le retour ou pas nécessaire ?

Merci beaucoup de vos lumières

Blue Smart IP65 12/15 charge while under load?

I use this charger for a LiFePo4 battery from BattleBorn. I am re-doing my setup and was wondering if it is safe to leave the charger connected to the battery all the time so that when mains power is available I can plug it in and have it charge the battery while the load connected to the battery continues to run? I believe I have seen that this is okay but wanted to confirm. Secondarily I have the function set to charger - would I need to switch that to power supply or can I just leave it as charger?

Thank you!

Not Turning On - Victron Orion-Tr Smart DC-DC Charger (12/12-30 isolated)

Hi there, thanks in advance for any help you can provide.

I've just finished my solar setup in our small van and turned everything on. Everything appears to be working properly except the DC Charger is not powering on. My MPPT solar charge controller right next to it powered on just fine. Any tips from the community on how I can check what the problem might be?


  • 2 x 100ah 12v LiFePO4 batteries wired in parallel
  • Negative from Batteries run through Victron's BMV712 Smart Shunt, and then to Blue sea systems Safety Hub 150 fuse block, and from the fuse block I run a ground to the van chassis
  • Positive from batteries run through a fuse, then through a cutoff switch, and then finally over to the positive side of the Safety Hub 150
  • DC charger is wired from Alternator
    • DC Charger is not yet connected to the alternator, as I need to power off my starter battery from what I have read
    • and yes, it is actually more convenient and shorter to run 6AWG cable from my alternator, about 6-8ft, than it is from my starter battery 10+ feet and more difficult
  • Wire from Alternator is ran through a fuse, and then to a cutoff switch, finally ending in the DC charger
  • DC Charger to Safety Hub Fuseblock is very close, less than a foot, and the wire is 8AWG
  • Voltemeter test says there are 17-20 volts on the output posts

Does this sound like the unit itself malfunctioned somehow, or did I set something up wrong? I shouldn't need to connect the charger itself to the Starter Battery or the Alternator for this to work, as long as I have it connected to the battery bank, correct?

Switch charger Multiplus ON OFF

Hi everybody,

I've tried to dig into all questions and answer but it seems that my question is never asked before.
If the opposite please my apologise from now. Please send me the link of the previous post.

I'm moving from gel battery to DIY LiFePo4 batteries.
I've just bought a new charger, the Multiplus 12/3000/120.
I've already installed on board BMV712 and Venus OS on a Raspberry Pi3

When I'm in the marina, connected to the shore power, I would like to charge the battery up to 85% of their capacity and switch off the charger, but continue to use the shore power and the inverter if necessary (power off, more energy etc). Then switch ON again the charger at 40% of the batteries capacity.

As I can see the phisical remote can have only Charger ON or Charger/Inverter ON or all OFF.

I see that using the relay of my BMV712, at 85% of the capacity I can open/close the contact and with another bigger relay cut the shore power off, and on again at 40%. But with this setup when the shore power is off I shall would use only the inverter.

Is there any possibility to switch off only the charger function and keep the shore power?

Today did I Observe on the batterymonitor that the charger didn’t charge my battery bank as expected.

Checked the shore power, 230 volt.

When I checked the LEDs on the IP43 charger:

All LEDs on including ALERT/ALARM led

Followed by only BULK led on.

My interpretation is: Bulk time protection

I expected to see bulk, floating etc

Have nerver before faced any alarms.

What criteria has caused this bulk time protection?

Will it start to charge after some ”protection time out”?

Don’t like this status now with sound from a Relay and leds flashing

Help programming Phoenix Charger 12/30

Hi there,

I need some help programming the Phoenix Charger model 12/30. I have followed the manual as best I can, but nothing seems to work.

I first tried to program it without the remote control, using a voltmeter. I switched it on as instructed in the manual, and the correct LEDs were alternately blinking. However the voltage on the voltmeter, in DC mode, was way off - around 40-50 millivolts, whereas the manual said it would be in the 12-16 volt range. I was hooked up to the positive and negative just like it suggested. Additionally, the up and down buttons had no effect.

I then tried to program it with the remote control, and it was entering into all the correct modes (based on the LED patterns), however, I was unable to actually alter any of the voltage settings using the up and down buttons on the circuit board. No matter how many times I clicked or in which direction, the LEDs on the remote never changed their flashing patterns.

Am I missing something? I have the batteries disconnected, and there is no voltage or temperature sensor either. I just have it plugged into mains and following the instructions.

I have contracted my distributor but so far they have not helped me.

Thank you for your help!

Victron Blue Smart IP22 Bluetooth Battery Charger setup for parallel batteries

Hi Everyone - I'm hoping you can help with a question I have on the best choice of AC>DC charger, and the setup for my planned battery configuration in my van build

At the moment I have three 95Ah AGM batteries that are hooked up in parallel that i want to charge using a Blue Smart AC>DC charger from my shore power system, and i'm wondering whether it's best to go with the 30A single output charger, with the pos and neg going to the batteries at the opposing end of the parallel bank, or potentially go with the 15A 3 output charger with each battery having its own pos connection and the neg's all running to a common bus bar? All options with fuses at the battery end of course.

Are there any benefits or drawbacks to either approach?

Does anyone have a similar setup to either option and can provide any good feedback on their choice?

Lion Energy UT1300 105Ahr and Victron BMV+SmartSolar MPPT 150/70 + xantrex charger

Good day. I have a boat that I will be on for 2-4 weeks at a time and using for living, cooking, lighting, etc as a what people call a working system. I have 3 items I need setup properly. Can you all assist with settings? I have a Victron BMV 712, Victron 150/70 MPPT (870watts), Xantrex 150amp charger/inverter, and 4 Lion Energy Safari UT1300 105ah lithiums.

1st priority is longevity of my batteries, but a very close second is:

Fast charging. I have to burn precious diesel to run generator (maintenance/fuel) to use the Xantrex charger. And, my solar is on a boat and thus never optimally positioned so I need to maximize my Victron MPPT 150/70 when I get sun. I cannot wait around for slow charging my lithium batteries as I only have 400 amp hours and uses 200-300 per day and need it back daily.

MPPT settings:
Battery: User
Absorption: 13.9
Float: 13.9
Equalization: 0
Temp comp: off. battery should do it.
low temp cutoff: off battery BMS should do it.

BMV 712:
Capacity: 420 Ahr
Charged voltage: 13.9/14.0
Tail current: 4%
Charge detection time: 3-5 minutes
Peukert exponent: 1.05
Charge Efficiency factor: 99%
Current threshold: 8 amps (2% of capacity?)
Time to go average: 3min
Zantrex 150 amp charger.
Bulk: no setting, constant amps till reaches absorption voltage.
Absorption: 13.9 - 14.2. Cannot decide what to enter.
float: 13.5 to 13.9 . I don't know what to enter.

Absorption time: lowest possible I can set to. Under 30 minutes.
No equalization
No temp compensation
Invert low volt shutdown: 11.5 safe value. How much am I leaving in capacity at 11.5 vs 10v?
Recovery. 12 or 12.2 volts. Not sure what to enter.

Charger for 800Ah battery bank

So my questions are:
1) Should I set the bank at 12V or 24V (I'm leaning towards 24V for the option of connecting a DC-DC converter to charge my 12V the "House" batteries: (2 * 125Ah), Lithium.
2) Which Charger should I consider when connected to Shore/Gen power (120V/30A service).?

DC Loads Increase - with high Multiplus charge rate

Hi All

I wonder if anyone can explain a strange issue I am seeing on my system...

Set up - 3x Lithium (3x 200A), VE.Bus BMS, Venus GX, BMV712 and Multiplus (EasyPlus 12/1600/70 - set to 70A charge current max).

Example of situation / what I am seeing -

  • I leave the boat for a few days
  • with a constant load of about 1.5A on batteries
  • I arrive back at boat - and BMV says state of charge is 90%
  • all good so far

I plug shore power in - and switch Multi on - and do NOT switch on anything else -

  • it goes straight to Bulk - good.
  • If I look in Venus at the Multiplus - it says it is generating 70A - good.
  • I look at the BMV - and it says it has about 60A going in to batteries - strange
  • I expect the current going in to batteries to be about 68.5A (charge current - loads)
  • where are the other 10A going / being lost ?
  • I look on VRM and see DC Power showing my DC loads are pulling about 10A
  • but this is not true - the loads / devices are only about 1.5A
  • I have not switched any other loads on

This false high DC loads figure (about 10A) stays while charging Amp are high (in bulk). When multi goes to absorption - the false high DC loads (10A) reduces in line with the drop of charging Amps. I watch the 10A loads reading slowly drop to 1.5A as the multi reduces its charge current from 70A to almost nothing. Then - in float - the DC loads read accurately - 1.5A.

Any thoughts on what the issue is ?

Repeat Absorption Interval

Multiplus and Skylla Chargers: Is the repeat absorption interval re-set when power to the charger is disconnected or does charger continue to time the current interval even if power is cycled?

Lithium batteries on a sailboat. Want to control when bats are pushed into bulk/absorption voltage to reduce un-necessary wear. Plan to enable "Watch function" on Skylla (start-up in storage if battery voltage >=13 V.). And set repeat absorption interval to 15 days (to allow cells to re-balance). Want to avoided charger from entering bulk/absorb voltages when charger is plugged back in if batteries are at or above float/storage voltage. Concern is the repeat absorption interval will re-set every time the boat is unplugged from the dock and not go into repeat absorption mode if power is regularly cycled inside of 15 days. Charger will always start in storage mode if voltage above 13v. Therefore Bulk/absorption voltage never reached for cell balancing.

Keep charger on or of when batteries under small load?

Dear all,

I am wondering:

Regarding what i read and hear the best to do with (in this case) AGM- deep cycle and super cycle batteries is following, in short:

- Always after use charge battery to full and after that, disconnect charger.

- If not used a fully charged battery for a period: After 1 or 2 months charge batteries again for maintenance purposes and to make sure a complete charge cycle is made.

- Do not interrupt charge when charging a fully charged battery, so do not charge batteries if not necessary and when it is not possible to finsih a complete charge cycle.

In my case:

I have a color control connected to a multiplus 12 volt, connected to 2 x 230 Ah in parallel.

The system can be monitored by the gsm module, so i have a constant network connection. Power drain in standby is around 0,2 amps due to data connection etc. When i use remote console, power drain is around 0,3-0,4 amps. So in other words: i am superslowly draining the batteries.


Do i keep the charger on or off when in standby? For my understanding, it is not very healthy to keep a charger always on whe u store batteries, even not when it has storage mode (see above for my understanding)

But in this case i am slowly draining the batteries, so is it better to leave the charger on when i am not on the boat for like 2 weeks?

For what i do now when i leave the boat:

I charge the batteries to 100 percent. I keep the color control online. After 2 weeks, the day before i go to the boat, i turn on the charger remotely.

Is this the best thing to do?

Best regards, Piet
