Smart BMS Cl 12/100 Multiplus Compatibility

Hi there

I note in the manual for the Smart BMS Cl 12/100 that the Multiplus 3kva must be of 'recent type' with auxillary inputs. I bought my Multiplus 12/3000/120 about 6 months ago. Can anyone tell me if this version is compatible, picture below of the inputs on my unit.

MultiPlus with a BMS CL 12-100 -- Load and Charge Disconnect Not Working

Hi All

Help please...

My Multiplus (EasyPlus Compact 12/1600/70) will not switch off when instructed to by the BMS (Smart BMS CL 12-100). My set up is as per below -


I am using the Cable for Smart BMS CL 12-100 to MultiPlus (PN: ASS070200100). I have tested the V output from the load and charge disconnect on the BMS - they are performing as expected (both normally high). But when the BMS changes to load or charge disconnect - the Multiplus stays on. The V on the cable becomes free floating, as expected, but makes no difference to the Multiplus.

I have connected the Cable as per instructions which states - "When used with the MultiPlus Compact 800VA-2kVA models connect the black wire to the middle terminal and the red wire to the right (IN) terminal."

From the Multiplus manual - I have plugged the cable in as per below - black to terminal 2 and red to terminal 3.


I am expecting the Multiplus to switch off when either load or charge disconnect become free floating - but the Multiplus stays on.

Any help / advice would be appreciated.

Disconnecting Large DC Loads

Hi! I've been searching here, but haven't found any discussion around this question.

I'm looking at setting up a large lithium house bank on a boat (800Ah) to drive both DC loads and a multiplus inverter and a VE.Bus BMS. I understand that the BMS should be able to switch the load off under certain conditions. The suggested route is to use a BatteryProtect, and the remote option on the Multiplus.

Switching the Multiplus seems straightforward, but switching the large DC load less so. Max DC ampacity for the load is roughly 600A, although the highest current draws are very intermittent — windlass (100A), electric winches (200A x 2). Even so, my understanding is that I need to switch everything off when indicated by the BMS.

The largest constant current ampacity I see for the BatteryProtect is 220A. While some loads are intermittent, when in use, they may be used for minutes at a time, so I think I must remain within the continuous current rating for the Battery Protect.

What's the best way to switch this DC load?

I've considered paralleling several BatteryProtects, both on the load and on the signaling circuits, but I'm currently leaning towards a 600A contactor with 4000A surge rating, despite the appearance that the signal from the BMS will likely need to drive a relay to provide the necessary current to the contactor.

Please advise.

Red Led is on BMS CL 12V 100


I have just finished an install of Victron Lithium Batteries. I have multiplus 3k 120v which I have programmed the assistants. The BMS is powered by the start battery. When I power on the lithium’s I get a red led indicating over temperature. My batteries both are within range temperature wise and n o alarms. I am afraid to keep commissioning as the next step is to run the alternator which I don’t want to do until I understand the Red led light.

Orion-Tr Smart, VE.Direct and integration with GX devices?

Hey there, as I commented on the blog post,

"I'm curious if future versions will have VE.Direct or some sort of integration like that with GX devices? Currently, it seems that the MPPT and MultiPlus are able to coordinate their total charge rate with external BMS via the GX devices. But it seems that the Orion-Tr does not participate in this?"

I'm wondering if there's a way to integrate the Orion-Tr Smart chargers with the CCGX. In particular, as far as I understand, GX devices can coordinate with external BMS via CANBus to determine the charging parameters of a battery. It seems that the Victron MPPT and Victron MultiPlus can respect these limits via VE.Direct and VE.Bus respectively, which is great and a big reason why I bought this BMS and the suite of Victron product.

Now I'm considering purchasing Orion-Tr Smart chargers, however I noticed that they don't have any VE.Direct connectivity, or any other VE connectivity aside from the Bluetooth one. Is something like VE.Direct, VE.Bus or VE.Can planned? Will Orion-Tr Smart chargers integrate with GX devices?

VE Lithium Battery Bank, Which BMS to Use?

Hi All,

I appreciate that this question may come down to preference, but I would greatly appreciate anyone's input on this if possible. My dad and I are currently installing the VE setup I've purchased for my liveaboard, which includes:

3 x 100ah Lifepo4 batteries

1 x Multiplus 12/3000/120

1 x BMS 12/200

1 x BMV 712 shunt

2 x Power In Bus bars

1 x Cerbo GX & Monitor

1 x Standard 105ah lead acid starter battery

70amp alternator

The Victron setup above was recommended to us by the agent who I purchased it from. Since then we have done a good bit of research on the Victron setup, and we are now questioning whether the BMS 12/200 is the best option for our setup... Would anyone recommend the Smart BMS CL 12/100 and or the VE.Bus BMS along with the Cyrix Li Ct?

The Smart BMS does not appear to limit the current draw of the house batteries which the BMS 12/200 does appear to do. The Smart BMS also appears to offer better protection to the starter battery..

Can anyone weigh in on their experience or opinion of these BMS options?

Cheers, David

VECan BMS+Skylla IP65 12/70 1+1 / Current control

Dear Community,

I would like to request your help regarding setup of a Skylla IP65 12/70 1+1 connected on VE.CAN to a intelligent BMS.

A REC-ABMS is issuing CVL, CCL and DCL data (respectively Charge Voltage Limit, Charge Current Limit and Discharge Current Limit). Data appears correctly on a GX display.
The Skylla is also connected to the GX display and data appears ax expected on the same GX display.

I would like to configure the Skylla so it follows CVL and CCL values. I have enabled the BMS Present feature (#31) but this lead to the following error after apporximately 10s : "error 67 : BMS connection lost".

I would be very grateful if someone could help suggesting the setup necessary to get the Skylla to honour the CVL and CCL data.

Powering Smart BMS Cl 12/100 from Lithium batter with a diode

I have a boat where I am installing Victron Smart Lithium batteries ( 2 x 200 Ah). I have a Smart BMS CL 12/100 to manage the charge sources ( MPPT 100-50 + and Phoenix IP43) plus loads ( Smart battery protect 12-220)

In all diagrams, input of the BMS is connected to the alternator and the starter battery for power. However, in my case, the output of the alternator is connected to a MOSFET battery splitter , which feeds the service battery, the starter battery and the bow thruster battery from three separate outputs.

Since BMS CL 12-100 takes its power from starter battery connected to the input port, due to the battery splitter, the starter battery will not provide power to BMS unless alternator is running. This means BMS will not enable the chargers and the Battery protec, thus isolating the batteries.

My solution is to have a cable from lithium batteries connected to the alternator input of the BMS with a diode. This configuration did work in my test setup. But I need to get a confirmation that it will not cause any issue before wiring the boat.

Will this cause an issue when the alternator is running

ESS mode ignores BMS BMZ ESS-X control

I would like to ask if it is normal that ESS mode ignores BMS control from BMZ ESS X battery. Configuration 3 x MPII, 3 x BMZ ESS-X, MPPT 250/85, Fronius Symo and AC OUT1, Cebo. All devices have the latest version of FW. Unfortunately even if the BMS battery sends a parameter - CCL = 0A:




so the batteries are still charging. The charger is set according to the manual for BMZ = Absobrtion time = 1. Unfortunately = Absobrtion time is never one hour, even 7 hours at a time.


Status code # 3 should appear in ESS mode: BMS disabled charging, I've never seen it with BMZ ESS X in ESS mode. I run another 4 similar systems with BMZ ESS X and I have also never seen status code # 3: BMS disabled charging.

I'm worried about the batteries, about the safety of operation. I think I overcharge them this way and they could be damaged. Please tell me if this behavior is normal (the battery is not overcharging) or if it is an error. Thanks Ondra

Connect ve.bus BMS to Venus GX

I have a Lithium system with ve.bus BMS and want to know the cell voltages. I don't have the Smart variety batteries. I also want the other benefits of having the BMS talk with the Venus.

According to the CCGX manual, one can connect the BMS directly to the CCGX and I would assume by extension, to the Venus. I quote from the manual with regards to the be.bus BMS:

"Connect the CCGX to the socket labelled ‘MultiPlus/Quattro’, or to one of the Multis/Quattros in the system. Do not connect it to the Remote panel socket on the VE.Bus BMS."

I have not been able to get the BMS to show up as a device on the Venus, but all my other devices do. I have contacted my dealer who assured me I should be plugging the Venus into the "remote panel" socket on the BMS even when I quoted him the manual. This did not do anything, either.

Someone else on here asked a similar question and was told they could not be connected. Given that the bus is merely passing on data, I don't see why it should not work, but with all the contradicting information I don't know what to do.

Any advice would be appreciated.

Multiplus is tripping Battle Born battery BMS

Hello, I have a Multiplus 2000/12 connected to a single Battle Born Lithium battery. Every now and then when I turn the Multiplus on (using on/off switch, not the hard switch on the Multiplus) it trips the BMS on the Battle born. Then I have to disconnect the battery and reconnect to reset the BMS. I have no idea what is causing this. This usually starts happening when I turn off the power to the Multiplus without turning off the Multiplus first. Then it starts this vicious cycle of tripping the battery every time I send power to the Multiplus. I have checked all the wires and everything is tight and isolated. It almost seems like something is bad with the Multiplus or Battle Born. Both the Multiplus and Battle born are brand new. I haven't even started using the Inverter yet just the charging.

I did fire up the inverter on a test run and the buzzing was really loud (normal?) and then it too tripped the BMS after 2-3 seconds.

Thanks for any help. I live in Colorado and I can't find anyone I can pay to come and help figure it out. It seems even the distributors of Victron don't know how to service them. Also, I have had Victron pros in this community validate my schematics, but happy to post again.

The starter battery is above the voltage needed but I'm still not getting any charge into the battery. I'm getting an alert saying that undervoltage protection is activated even though its registering the Lithiums and starter above the cut off limits?

Is this because I'm using a none victron battery and the 2 bms cable aren't connected?

REC-BMS for Victron / Multiplus 24/3000 / Control Load busbar


I'm pretty new to LiFeYPO4 (coming from normal batteries) and I want to build a Victron system using Winston LiFeYPO4 batteries with REC SI BMS for Victron. I intend to build a 2p8s system which is connected to the BMS.

REC BMS communicates with Victron via CAN and CCGX will be configured with DVCC to let the BMS decide the whole charging thing.

My issue is regarding the LOAD:

In all Lithium Victron diagrams (e.g. here) a Smart Battery Protect is used to switch loads on and of. SBP is controlled by VE-BUS BMS via the load disconnect signal. But with REC-BMS I have no clue to accieve this...

Is it possible to use the alarm relay of CCGX? REC BMS also has an optocoupler but the manual says this is only for charging...

My questions are:

Is it correct that in case of undervoltage the inverter of the MPII is switche off via CAN?

Has anybody an idea how to switch of all 24/12v loads in a Victron environment using REC BMS for Victron?

Any ideas appreciated.

Why can't I connect the CCGX VE Bus to VE BUS BMS ?

Just wondering if anyone can give a valid reason why the CCGX cannot connect to the 'remote' terminal on the VE Bus on the BMS. It says in the BMS manual to connect it to the Multi. But when I have tried it out everything seems to work as normal and I can even see the Multi on the CCGX as it is connected on the "multi/quattro" terminal of the BMS. The only thing that seems to happen is the 'Enable" light goes off on the BMS. Just asking out of interest and because the Multi is a much longer run through the boat and I had forgotten to do it when I ran the other one.

victron bms wont allow quattro to charge or invert.


I have been having some issues with my system after i added a 3rd smart battery.

Firstly the Quattro would only turn on when i did a re-detect on the CCGX. But after then it would operate as normal.

We went away last weekend and i noticed the batteries were down to 30% when i raedy to come home. , however we were on shore power. The quattro was marked on the CCGX as in pass-thro mode although the unit was physically switched to ON.

When i checked the graphs in VRM the unit operated correctly Inverting as we tavelled then charging the batteries on arrival when connected to shore power.. Soon a the unit switches to passthrough mode where it stayed.

When i got back i have updated the firmwire in both the ccGx and the Quattro to the latest.

On completion this allowed the Quattro to Charge.

But this was because i updated the Quattro using the Android connect app and despite configuring the charge settings for Lithium i then had to use the remote vrm to reload the ve bms assistant.

As soon as i uploaded the assistant the Quattro went back into pass thro mode which allows just the AC through to power connected loads on the AC out but nothing else.

SO i can assume the VE BMS is telling the Quattro not to allow charge or discharge.

I also have a red low battery flashing red light on the Quattro. my Batteries are not low they are now at 79%. No faults showing on the bms etc

I have attached a rough schematic of my system .


I have also attached a screenshot of the widgets if this helps at the point the inverter changed to passthro


On my CCGX settings the VE bus shows

"an assistent is loaded an configured for a BMS but none can be found"

the settings box for the bms has allow to charge / discharge disabled and BMS error as YES

I intend to check all my RG45 leadsand wires etc as a first port of call tomorrow.

I will also connect the batteries individually to see if there is a problem there although they all look fine on the connect app

But what else should I check?

i was considering swapping the bms for another to cross out that being faulty?

I would really appreciate some help with this one
