IP22 skipping Bulk, straight to Absorption

I have 2x Victron Smart 100Ah LiFePO, managed by a 12/200 BMS & SmartBMV. I connected the IP22 today as they were at 50% (102Ah discharged). Usually the solar keeps everything topped off, but we've been somewhere shady for a week.

Bulk - 1m57s - 0.7Ah
Abs - 1h56m - 42.2Ah
Storage - 10m - 3Ah
at which point I pulled the plug.

I've checked the fuse. All the connections are good, straight on to the BMS. Voltages (currently 13.47 &13.48 with all cells balanced) are correct and agree on the different devices.

Reconnecting the charger again starts the process again; this time Bulk for 4s, then straight to Abs.

I think that this started when I installed firmware 3.40. It definitely didn't do it when I first purchased it in December. Looking at the History tab, it's only been the last 5 cycles where this has occurred. No changes have been made to the setup since December.

Comment réinitialiser le calcul du pourcentage charge du Multiplus II 48/3000/35-32


Je bataille depuis quelques jours avec le paramétrage de mon Multiplus pour essayer d'obtenir un pourcentage de charge juste. Le pourcentage a été à 100% lorsque j'ai paramatré pour la première fois il y a 1 semaine, et depuis il baisse (inférieur à 50 %). CE qui est faux car tous les jours en milieu de journée j'atteints la phase float et une tension de 55 V. Je voudrais réinitialiser le calcul du pourcentage du niveau de charge, mais je n'ai pas trouvé cette fonction, ni dans les menus du Multiplus via VictronConnect, ni dans ceux du régulateur de charge, ni dans le Color GX. Auriez-vous une idée ?

Quelqu'un sait pourquoi le calcul du pourcentage devient farfelus ?

Merci d'avance pour votre aide.

cerbo gx bluetooth disappeared

I have two cerbo gx devices on different battery banks, they have been set up almost identical aside for voltages, both are connected to the same wi-fi, both have REC BMS integrated. They were both working fine for some time, then oneday the bluetooth on one of them just stopped working. No blinking blue light. I have searched and can't find where to re-enable it nor does reset work.

I can still access it [the cerbo] via the cerbo inbuilt wifi but can't find where to enable the bluetooth again. The other cerbo does not have this issue.

Multiplus II automatic on/off with cerbo gx and VE.BUS

Hi I know similar has been asked in the past, but I have not yet been able to find a solution. Maybe someone else has come up with something?

I am two lithium, a 48v bank and a 12v bank, on my sailboat. I normally live aboard, but this winter I will be leaving the boat for an extended period. I would like to run a far infrared heater and dehumidifier whilst I am away. I have 1.2kw of solar so should be able to handle almost continuous use. Though what I would like to do is only run them when the batteries are charged up to say 70%, thus ensuring that if there are a few days of no sun and the battery drops bellow this level the inverter (and devices it is running) won't running the battery down.

Is there a way I can do this? Note that I am running REC BMS which controls the charging via the cerbo gx.

generator erattic charging with quattro fronius AC coupled off grid

Hi, i'm wondering if anyone can help with my generator to quattro charging issue. I have an AC coupled off grid system with 2 x fronius primo 8.2 ( each carrying 8700w of PV ) feeding into a Victron Quattro 15000va inverter and a 27kwh Kokam lithium battery.

The generator is a 25kva which is all hooked up to auto start. At first it worked fine but recently when it starts the quattro is drawing the power very erratically and the charge current from the quattro is all over the place but at a much lower rate than its capable of. Sometimes the generator will level out as normal if I start a big load such the mig welder or the toaster and kettle together would do the trick and other times nothing works.

Also sometimes during the day the fronius's will shut down several times and if we are drawing more than the Victron can handle it will shut down due to overload as the fronius aren't helping anymore and needs to be restarted.

If anyone can help it would be much appreciated.

Thanks lee

Multiplus overheating before overload

Greetings, I have a multiplus 48/3000 which has been working fine for years. I have now installed a 2.5kW load, which I need to run for an hour or so. After half an hour I get temperature warnings, the multiplus goes offline for a few minutes, restarts, operates for 5 minutes, another warning etc.

There are no other loads on the system, and vrm portal is showing a consistent load of 2500W.

The multiplus is installed with lots of free space around it, and the ambient temperature is about 22C. The fan is working hard.

Any ideas how to correct this?

SBP-65 controlled by Remote BMV Temperature AND High Voltage?


I'd like to use a SBP to control a 24v seawater airconditioner for cooling lithium cells while charging.

High Battery Temperature via Remote Port (Smart BMV-712 alarm/relay)

High System Voltage (as approximation of Solar absorb phase) via SBP internal sensor (e.g. >3.35V@Cell or >26,8V@24V)

Can this be done with a single SBP or would I need to use two SBP in series? (1: voltage, 2: remote)

Or even better: Can I use two remotes (H&L) from Smart MPPT Absoption relay and Temperature from BMV on a single SBP?

Mppt max Wattage input

Hi , ive tried and find my answer many places but cannot get it anywhere .

Im looking at getting an MPPT whose spec says as follow

Max. Photovoltaic System Input Power 550W/12V

1040W /24

It seems to be very easily archived to reach 550W with just a couple of panels and was wondering in order to benefit best from the mppt i would like to go into a 24 V so that i can input 1040W .

Would this count as 24 V if i was to put the panels in series and up the voltage? Or do the panels have to be 24V themselves ?

24V panels seem a lot more expensive and a lot harder to get which is why i would rather go the 12 V way but also would like to maximise the utilisation of the mppt .

Can I use 2 Solar controllers in the same system?


I realize that this question was asked and answered a few years back however I am confused by part of the accepted response:

"Any MPPT (or PWM) solar charger, has a limit to how much Wp it can handle, eg. the max Wp of a 100/150 or 100/250 SmartSolar is 5 800Wp.

It also does not have to be the same size MPPT's, or the same size panels.

But make sure that all the panels on a single MPPT, is the same size. You don't want to mix sizes in a single array, as they will all be derated to the smallest panel. Eg, 2 x 150Wp, mixed with 2 x 250Wp in same array, will all be derated to 150Wp. As if you had 4 x 150Wp."

Regarding the underlined part, is there something special about Victron MPPT controllers that do not allow mixed wattage panels in parallel? To be more specific, in my case, I have 3 x 170W (8.6A ea.) and 1 x 100W panels and they are all 12V (the 180s are fractionally lower in V than the 100). I was planning to hook two 170W panels together in series and feed my 200Ah LiFEPO4 battery via a Victron 20A SmartSolar MPPT controller then run the 3rd 170W and the 100W panels together in parallel through a 15 A MPPT to the same battery. Is there any problem with that? What derating would occur?

As a less preferred alternative, can I not hook them all up in parallel and use a 35A controller?

Any help with this would be appreciated,

IP22 charger cycling between BULK and ABSORPTION too quickly


I'm charging a 250 AH li-ion batterie equipped with an internal BMS.

When connected to mains, the charger start in BULK charging at 30A, and quickly switches to ABS (around 3A, which is correct).

But a few dozen of seconds later, it goes back to BULK charging at 30A, and a minute later back to ABS, and cycles like this.

Load on the battery is light at this time (around 10W), and from my understanding, ABS should maintain a fixed voltage and provide the current absorbed by the battery (+load). No reason to switch back to BULK charging.

I see alternating BULK (buzzing) /ABS (silent) every minute. I'm providing four screenshots of the app with phone's time to illustrate.





Any idea on what could be causing this ?

MultiPlus-II 2x 120V - Feed grid and use as ups.

1. Can this model feed solar energy back to the grid in the USA?

2. Assuming I already have Victron mppt controller and a 48v battery, do I need a separate grid tie inverter (for example Solaredge) to use this model with the grid?

3. Can this be wired up to the main breaker box? The following data seems to imply that it’s connected to a panel with major appliances. If my “critical loads” are just the 120v outlets, then I should not need a separate breaker box, correct?
The MultiPlus switches to inverter operation when no AC source is available. The inverter output is also 120V single phase. In inverter mode, the MultiPlus-II 2x120V internally connects both lines L1 and L2 together to provide 120VAC to loads on either output. Therefore, in all connection circumstances, both sides of a distribution panel will be supplied with 120V. However, 240VAC is only available when the MultiPlus is supplied by a split phase 120/240VAC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery.

4. what are the advantages of ac coupling this model with a pv inverter like the solaredge vs using this model by itself?

5. will this model allow the Victron controller to provide solar power and charge batteries during an outage?

6. Are there any victron installers in the Dallas Texas area?


If this can supply power to the grid, is it limited to 3,000 VA of power going back to the grid? let’s say I have 4,500 watts of solar panels, how much of that can be sent to the grid?

SmartSolar not using VE.Smart current sense

I have a setup where a SmartSolar 150|70 is connected to a BMV-712 on a VE.Smart network. The BMV-712 monitors the battery bank.

As shown on the pictures below, the SmartSolar is taking external battery voltage and temperature from the VE.Smart network, but not external battery current, which mean the SmartSolar is not able to detect the tail current during absorption if any load is present on the DC circuit causing the current at the SmartSolar sensor to be much higher than actual charge current in the battery.

Is this a known issue, is there a reason why the SmartSolar does not use external current sense? Is Victron planning to add this as a feature in the future? That would be really helpful to help the charge controller manage end of charge much more accurately...



Smartsolar view of VE.Smart network: it uses external battery voltage and temp as expected, but not external current sense


BMV-712 view: as expected, BMV-712 does send current sense, but it is not being used by SmartSolar:

Auto Transformer

I have a question regarding the capabilities of the 100A Auto Transformer that Victron make.

I want to make sure my understanding of this unit is correct and this is hopefully a basic question for somebody. I notice that it states that the neutral continuous current capability is 28A AC and from the documentation it implies this is effectively the limit of the imbalance the system can absorb. My two hypothetical questions are:

1. If this transformer was being fed by a 12KVA 240V supply with the output exclusively feeding 120V loads balanced across L1 to N and L2 to N. With the maximum imbalance limitation of 28A would the maximum theoretical UNBALANCED load it could provide on it's outputs be 64A on one leg and 36A on the other?

2. If this same transformer was feeding a system exclusively made up of 120V loads on L1 to N and L2 to N i.e no 240V loads. If absolutely NO loads were present on L2, would the theoretical maximum current on L1 of the transformer be limited by the neutral imbalance limitation of 28A. So this would limit any current to 28A (3.36KVA) on any leg if the opposing leg was 0A?

Appreciate any guidance on this please. Thanks
