Meine Anlage besteht aktuell aus
1x EasySolar 2 mit GX
2x MultiPlus 2
Als Batterie sind derzeit 4 Pylontech US3000C im Einsatz.
Nun habe ich zwei weitere MPPT 250/70 ve.Can geordert und wollte diese in Betrieb nehmen.
Leider ohne Erfolg, da ich keinen ve.Can Anschluss am EasySolar habe.
Wie kann ich trotz des EasySolars2 GX einen ve.Can bekommen?
Gibt es hier seitens Victron eine Lösung?
Durch recherchen bin auf auf "Victron VE.Bus to VE.Can interface" gestoßen.
Leider weiß ich allerdings nicht, ob das Interface funktioniert am EasySolar2 GX, oder benötige ich einen Cerbo z.B um die beiden weiteren MPPT ve.Can in Betrieb zunehmen.
Vielen Dank, für eure Hilfen
There is a CCGX with 3x Blue Solar 150/85 mppts connected via VE.can with a terminator in the other port.
Need has arisen to connect lithium batteries which require can coms to control charging. Dilemma is whether can connect the BMS cable to the other Ve.can port occupied by the terminator or need to upgrade to CerboGX and use the other Ve.can port with terminator for BMS and the other port with terminator for Blue Solar?
Hi. Can somebody help me.
I try to communicate with a Cerbo GX with the Ve.CAN and a can Analyser.
My CAN_analyse_tool detect the bus on 250Kbps. So I know that the Can is connected.
But when I send a simple request like explain on the Victron VREGS Manual I dont receive any answer
For example I send
7.0.0.EF.20.40 0x66 0x99 0x01 0x00 0x01 0x02 0xFF 0xF
And receive no answer.
Thanks for you help
I don't know if any of the engineers actually read this forum, but I'm hoping to find out the maximum allowable cable length for the VE. Can interface cables. I intend to build my own cables using high-quality shielded cable (probably Cat7) so the attenuation and interference should not be a problem. I only wonder what the maximum latency is...
I can find information on the maximum cable length on the VE. Bus. People on the forums are saying that they're having trouble with longer cables, but the literature seems to indicate that you should be fine as long as the total cable length doesn't exceed 100 meters. Therefore, I believe that these people would do better with larger shielded cables since the literature seems to indicate that they shouldn't have latency problems, but I have found no such literature for the VE. Can.
I'm trying to mount the GX 70 upstairs quite a ways from the battery room. I figured I'd just locate the Cerbo GX up next to the GX 70 location.
If anyone can help, or if anyone can tell me who to contact, I'd really appreciate it!
Dans la liste des appareils reliés au Cerbo GX, j’ai le SmartShunt et les batteries Pylontech, mais l’onduleur RS 48/6000 n’apparaît pas. Il est écrit « off » sur le graphique du GX Touch alors qu’il est allumé. Je l’ai relié au Cerbo GX d’un port VE.Can à un port VE.Can, avec un câble UTP RJ45 cat6, standard.
Avec le Cerbo GX est fournis deux embouts RJ45. J’en ai alors mis un dans le VE.Can inutilisé du Cerbo et l’autre dans l’onduleur. Ça ne change rien au problème. À quoi servent ces embouts au juste ?
Voyez-vous une solution ? C’est une nouvelle installation.
I have a Smart Solar 150/100-Tr VE.Can connected by VE.Can to a MG Energy Master LV (With 2 x 200Ah HE batteries) and a Color Control GX. There is also a Multiplus 24/3000/70-16 connected by VE.Bus on the same system.
I'm having an occasional 'Error 67 - BMS connection lost' from the Smart Solar but I have unfortunately been unable to pinpoint what exactly is causing the issue. It never happens when the solar is isolated but randomly when solar is generating. It does not automatically recover unless I clear the issue by isolating our solar panels and reconnecting. Is this a known issue with Smart Solar VE.Can variants? Details are below. Many thanks!

I'm shopping for a charger controller for my twelve 445W 49Voc solar panels and my 24V 525Ah LiFePo battery with a nice BMS. It's off-grid. The battery manufacturer says I should use a charge controller that supports VE.Can. is it sufficient to use a pair of "SmartSolar MPPT 250/100 VE.Can MC4"? Do I need a GX device or can I daisy-chain the charger controllers and battery BMS and be done with it?
can a Bluesolar 150/70 and a Smart solar 250/70 be connected to one batterybank and work together?
We allready have one pv array with a Bluesolar 150/70 charging the batterybank. But the batterybank is to big for this charger.
I want to install an extra array with a Smartsolar 250/70 charger.
Can a Bluesolar work together with a Smartsolar charger? Can the communication ports be connected?
Almost every ESS battery compatibility page notes that old VE.CAN BlueSolar (150/85 & 150/70) with the rectangular metal case does NOT support external BMSes, because the firmware does not implement the required control instructions.
On the face of it, this makes sense.
However, after a couple of years of this being the case, WHY has the feature not been implemented?
I currently have some of these devices, and they are essentially useless now.
I understand that firmware "space" might be an issue to add this feature, but would it not be possible to build a cut-down firmware that contains ONLY this feature and none of the standalone charging features? That way a "BMS-compatible" firmware can be flashed, since none of the other features matter then.
It really is a shame that these excellent chargers have basically been abandoned now, especially since they were marketed as the top-of-range models initially.
I have a system with 2000Ah Winston cells, REC BMS, Cerbo GX 2x Quattro's, MPPT's and a Skylla-i. When the stop charging signal is given from the Cerbo the Quattro's stop charging but the Skylla-i keeps charging. Does anybody have an idea how to solve this. A dirty way is to use a relay connected from the REC BMS direct to switch off the Skylla-i but I want to use that only when I get above the max cell voltage.
I have a Cerbo GX, the Ve.can starts with a terminator on the lynx, continues to the cerbo GX, and the second outlet is connected to the cable provided from Fischer Panda for one of the two generators.
the cable of Fischer panda, comes from a gateway from Fischer panda bus to Ve.Can.
my questions is how can I connect the second generator to Ve.Can?
Hello, I am using a Victron set up with BYD batteries. I have a ccgx with Quattro 48V|8000va|110amp. I have 2 BYD Boxes with a total of 20kW. The system had been working great since early 2020 and recently it started shutting off randomly with now errors recorded. So I read on the forums that some had issues when the VE.Bus going to the inverter would shut the system down when plugged in. So, when I could not get the inverter to turn on at all even with a reset I unplugged the VE.Bus network cable and it turned right on. I live in Zambia so I did trouble shooting with my supplier from South Africa over WhatsApp. We went through many different scenarios. We unplugged everything from the back of the ccgx and left the power cable connected and shut off the supply of power from the solar arrays. With the VE.Bus plugged in and connected to the inverter the system now came on. When I plugged in the VE.Can going to the BMS for the BYD the system again shut down. I connected everything back and whenever the VE.Bus and VE.can were both plugged it would go off. But if one or the other were unplugged it would run. I tested the network cable from the VE.Can to the BMS and it seemed to be okay. I swapped BMS's as both BYD boxes come with one and so I had a spare and it did the same, shut off. I tried with just 4 of the eight batteries and set the fuse addresses to the correct setting and it still shut off. I tried with just one battery and it still shut off. At the end of the day before the sun went down I connected everything back together and surprisingly it worked perfectly fine with VE.Can and VE.Bus plugged in to the BMS and Inverter. Now it has been 2 days and it is working fine. I just want to see if anyone may know what was causing my problem in case it starts happening again.
I had many High Battery Voltage Alarms after install today of the first 250/100 VE.Can
Good news is we now have another 3,920w Solar array working on the boat!
But the alarms were triggered by the MPPT relay output set at 28.00v and off at 27.90v. (I was hoping to use it to turn on a battery fan during charging)
Every time the MPPT hit 28v the alarm was triggered and cleared below 27.9v, but I didn't expect an alarm warning from setting the relay. (Simple FLA battery bank 28.90v Abs, so alarms were below Abs voltage)
Turning off the relay didn't stop the alarms, but setting the Voltage trigger points of the relay higher have at least stopped alarms for now.
Setting a disable alarm rule in VRM also didn't stop the alarms.
Smartsolar MPPT VE.Can 250/100 v3.04
These Settings stopped the alarms (Setting the relay to be triggered at a higher voltage than battery voltage):
VRM Rule that didn't stop the alarms:
I have a client with a 150/85 Ve.Can MPPT and 1260w of panels but he wants to add 840w more. Both of which charge the same battery bank. The current 150/85 is connected to a Color Control GX via a Ve.Direct cable. If I add another Ve.Can MPPT and use a RJ45 to connect them in parallel will the Ve.Direct to the GX display the information for both MPPTs?
I know that a RJ45 would of done this to the GX per the manual, but I can't find anywhere if the Ve.Direct will work the same.
Or should I just use the Smart Networking to put the MPPTs in parallel? And if I do that will the Ve.Direct send the info to the GX for both controllers?
The two MPPTs will be on different arrays and have thier own wires. It's just a pain to run another Ve.Direct or RJ45 to the GX, plus it will save the customer on labor cost.
What are the Amps -> mV values for the Lynx Shunt VE.Can 1000?
I have a Cerbo GX connected via VE.Can to a SmartSolar MPPT 150/70 VE.Can and a Lynx Shunt 1000 VE.Can. I have DVCC enabled as well as SCS, SVS, and STS. I have found that the MPPT changes charging states correctly according to the readings from the shunt. However, it is not compensating voltage according to the temperature reading from the shunt. The MPPT seems to be compensating from the initial ambient temperature as the standalone strategy. The MPPT has v3.05 firmware and the shunt has v1.08. Any help would be appreciated.
I am expecting a shipment of 16x280Ah prismatic LiFePO4 cells. It is my first experience with non-lead acid batteries. I understand that I need a BMS, but there is incredible selection and profound difference in cost between models. I currently have a Cerbo GX which I understand has two data busses, a CAN bus and a proprietary VE.bus. This paragraph is the entire sum of my BMS knowledge, +/-.
I want to find a BMS that integrates maximally with the Cerbo. I'm happy to pay for quality. I don't necessarily need it to be a "supported" solution by Victron, as long as it integrates well. In another group on DIY Powerwalls, Batrium seems to be the most popular name in BMS. Is anyone running a similar system to what I've described, with a Batrium BMS?
What other options do I have? I'm also impressed with REC-BMS, but it's very pricey. A couple other ones I've glanced at are 123Smart BMS, Tiny BMS, Chargery BMS and DIY BMS. Also Daly?
The two most important things to me are 1) safety and 2) integration with my Victron products. This will be a 16s, 48v (although it's not a strict design requirement) LiFePO4 battery with low-moderate current requirements (probably something like a 3000 watt inverter). Thanks for any input!
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.
Im looking into getting the curent voltage or any momentary information on the VE.Can.
I already looked into the VE.Can registers public pdf and looked through a lot of questions here. I did not find annything on this.
My settup consist of a Lynx Shunt VE.Can a Venus GX and a Smart Shunt (I am just testing at the moment).
So far i am able to reach the registers for the historic values however it would make my work a lot easier to get values such as momentary Voltage, current and consumed Ah since i am looking into integrating these Values into another system via a Can Bus connection.
Are there any registers that would give me these informations?
in december 2019 a great feature was added to the firmware 1.47 of the VE.direct MPPT chargers:
tail current mechanism improved: it can now use the real battery current. The current can be received via VE.Smart Networking (Bluetooth) as well as from a GX Device
This is a useful feature I'm using in most installations since it has been released. A week ago I tried to do the same with a VE.Can SmartSolar and unfortunately it doesn't seem to work at all.
The system consists of a CCGX, BMV700, Multiplus 5000 and VE.Can 250/100 SmartSolar. Other devices have been removed to keep things more simple.
There is no ESS/HUB assistant installed and therefore no active external control of the charger. Also no bluetooth smart network has been created and the firmware is up to date on all products. In the system the BMV is set as the default battery monitor to use and SOC syncs well with the multiplus. DVCC and SCS are enabled and SCS status is active. In the carger the absorption time is set to a fixed time with a tail current of 10A. If the current value falls below that value for more than one minute the charger should end absorption stage earlier and pass over to float. But it doesn't. Nevertheless DVCC is working with voltage, temperature and even current (tried a limit on the system). It seems the charger just has no use for the value "battery current" sent from the BMV and uses it's own current value instead to end absorption.
I have asked dealers, distributors and victron support, but all of them told me the charger would be able to do this without testing it. So I'd really appreciate if someone with a new CAN system (the old chargers can't) could test this. Of course a load must be switched on to have different current values between charger and BMV. I just want to know if this feature is working or has not been implemented yet and victron doesn't know about itself. If it works probably someone finds a mistake in my settings? I would prefer I made a mistake.
Thank you very much!
I have two BMV-700s hooked up via VE.direct to a Cerbo GX. I have the Cerbo GX integrated with a Raymarine Axiom 7 via the network port AND VE.can. I can access both BMV-700s via the Victron App on the Axiom. I can get only one of the BMV-700s to populate the Battery 1 data box on the Axiom. I can't get either BMV-700 to populate the Battery 2 data box on the Axiom. I read the instructions and can change the data instance of each BMV-700, but I can't change the instance to 1. I can change the instance to 2,3,9, or 0, but I can't change it to 1. I used Actisence NMEA Reader and a NGT-1 to change data instances. All equipment and software has been updated to the latest rev.
I have two SmartShunts connected to the Cerbo with VE.Direct.
As far as I understand the Cerbo puts the information on the VE.CAN.
Is there a table with the available VREG's? Is it similar to the Lynx Ion?
Which VREG's are sent periodically, which are send on change and which need to be requested?
We are installing lithium batteries with their own BMS working at 250 kbits/s using EasySolar-II GX and Multiplus-II GX units. It seems the Multiplus-II GX units do not have the 250 kbit/s baud rate option, as do all the other GX units.
Is there a way to get the Multiplus-II-GX to work at 250 kbit/s? Changing firmware perhaps?
The batteries have been tested with a Color Control GX and work fine. But it is not working with the Multiplus-II GX.
Any help is appreciated. We have 450 units of those standing by...
I'm trying to figure out how to take advantage of the tank monitoring capabilities in the CCGX. I know for resistive sending units I need the VE.Can resistive tank sender adapter... My only problem is I have three tanks (Fresh, grey, and black) and these adapters cost $400 each!!! I would end up spending more than twice as much on these "adapters" as I have invested in the CCGX itself.
So I started looking at options. For RV holding tank monitoring: SeeLevel II is pretty much considered the standard for high end monitoring. When i was looking at their product offerings I noticed they have sending units that support "RV-C" which is a CAN Bus based protocol. Since the VE.Can adapter simply converts the resistance it gets from the tank into CAN Bus messages... If the SeeLevel II sends CAN Bus messages to begin with then it *should* be fairly straightforward to just connect these to my existing VE Can bus (I already have a CAN bus between the CCGX and my Orion Lithum BMS system)
That's assuming that the RV-C messages sent by the SeeLevel II are compatible with whatever message format the VE.Can adapter sends. I'm hoping someone from Victron can help me out.
VRM firmware update freezes at status 'Querying VE.Direct devices...' after succesful update of the first SmartSolar Charger VE.Can 150/70 from v1.06 to v3.02.
There is no error message generated except the warning 'Installation too busy, realtime date link disabled'.
The SmartSolar Chargers VE.Can 150/70 are connected with VE.Direct to Venus GX v2.60
Any suggestions to fix this to update the leftover chargers without using local Bluetooth and without the need of travelling to the site in Corona times?
I currently have 5KVA Multiplus with a 150/70 VE.Can MPPT charge controller using ESS with CCGX.
My current VRLA batteries are in need of replacement and was looking at replacing them with Pylontech US2000B or US3000 batteries. According to this article its not possible
Is this still that case as it its not possible at all or are there limitations?
Good day. I have a CCGX with a VE.Direct MPPT, VE.CAN Freedom battery, VE.BUS Multi and a VE.BUS Digital Control. I want to monitor a tank as well. Will the VE.CAN Resistive Tank Sender Adaptor be able to communicate via VE.CAN as well. The battery bank is using the VE.CAN port
The documatation of the CAN registers "VE.Can registers" is mentioning in the examples node numbers.
From the document:
Victron Request (0x0001) for Firmware Version (0x0102) of node at address 0x40 from address 0x20: 7.0.0.EF.40.20 0x66 0x99 0x01 0x00 0x02 0x01 0xFF 0xFF
Where can I find an overview which Victron product is using which node number?
Thanks in advance!
I have a 2 x SmartSolar MPPT VE.Can 150/70 rev2, Smart lithium, MultiPlus, BMS, Cervo, etc, all Victron.
I have not found any clear documentation about the functionality one gets when connecting the SmartSolar MPPT via VE.Can or VE.Direct.
I connected them originally via VE.Can and no screens on the VenusOS would show if the MPPT's where working as a single pair, networked and in sync, or would get BMS Charge Disable signals from the Cerbo.
I have them connected via VE.Direct at the moment, and in the Cerbo there is now a "Networked operation" screen, under each charge controller. However BMS control is still No.
Is there any documentation or guidance that exists about the best protocol to use to connect the controllers and the benefits and features of each.
I really want to know if the BMS Charge Disconnect signal is passed through from VE.Direct to the MPPT's, can they work as a synchronised pair, can they get charge current (non ESS setup) from the Cerbo, etc.
