[Part 1] Connect Pylontech Battery to Victron Multiplus II

I describe how to wire Pylontech Batteries with Cerbo GX and Victron Multiplus 2. Also I show how to build your own BMS CAN to VE.CAN Cable Type B. All you need are some network cable patching tools.
It was good explanation. I did my bypass the same way, except, in my setup MCB on AC-In is breaking the neutral wire too. God knows, why future-me will need to power off the inverter, but I want to isolate it from home circuit.
I have a Cerbo GX and a Pylontech US5000 battery. Th battery has no CAN port. It has a A/CAN port, is this the same thing? It also has a console port and a contact port. The Cerbo GX also doesnt have a Can.BMS port, it has 2x VE.CAN ports. I have tried connecting my cable to all the ports in every possible configuration and the battery doesnt show up as a device in the Cerbo GX. Its driving me nuts.
Very good video ;)
Great, that helped me out! 🎉
Good video, very clear
Do you think I can use the Wi-Fi network generates by the inverter changer multiplus-ll GX to connect my PC just for the first installation of system telling that pylontech battery is connected to the system via Ve.Can interface? In other word, can I avoid to buy MK3 interface to config my ESS?
Thank you for the english version!
3.22 Connecting the inverter to pylontech. I have got pylon us3000c. Pylon gives to customer a cables kit in which there is a cable to connect BMS to the inverter. Can I use that cable instead to buy the original victron ones?
I have built a similar solar system but I have got the last model of multiplus-ll, i. e., GX model. My battery is Pylontech US3000C. I have also 2 MPPT solar charger. Your video is very useful because victron provide us a very flexible system to be implemented. Thank you
Hi Helmut, Thank you for the very clear instructions, can you do one for the Type A cable?
Brilliant, nice and simple for novices like me to get started 😃
This was very helpful! Thanks!!
What cable is needed to connect an EasySolar-II GX to Pylontech US2000 batteries (in parallel)? I've been looking but not sure if I've got it right. Seems to be a BMS-Can from the GX device in my Easy Solar to a type B Can input for the master battery? Anyone with a link to this kind of cable to ensure I don't somehow mess it up? :)
Why do you need an EM24?
It looks as though there are important info on GX devices that should be included at the end of this video. On the GX device, If your GX device has a BMS-Can port, the battery should be connected to this. If you connect the BMS to the VE.Can port you will need to adjust the port speed. Select the CAN-bus BMS (500 kbit/s) CAN-profile in the GX device. Menu path: Settings → Services → VE.CAN port. After properly wiring and setting the correct CAN-bus speed, the Pylontech will be visible as a battery in the device list.
Correct info. I have got an inverter multiplus-ll with Cerbo GX inside. Victron tries to hide this potential and many manuals are not updated too. In fact to configure the multiplus I don't need to buy MK3 interface because I connect my PC directly to the wi-fi network generated by the inverter himself.
If you connect Pylontech battery via VE.Can to the inverter and proceed to configure it, then setting the system selecting Pylon in the list of configuration after that the system knows exactly all battery parameters by BMS. In this case you don't need the smartshunt to know battery' S.O.C.
Thank you for the detail. I made a type A cable for the Multi II GX linking to a 5000W Vital-5 LiFePo4. I connected the VE.Can side to Multi ve.can port, inserted the terminator and on the other side into the Vital-5 battery BMS Can port. I however do not see the Vital-5 battery on the device list ! The Vital-5 has the same pin-outs as the Pylontech Type A. I there a special setting in the Multi II GX, to make it visible in the App ?
is it true that enphase handles shading better than hoymiles?
Thank you. super helpfull
Thank you. I run a very similar system but I leave the breaker between the mains and the Multiplus in the off position when I have enough power from solar and my 14KW battery bank. If the batteries are running low and there will be no sunshine for a few days I use the changeover switch to run the consumer circuits from the grid and leave the solar system to recharge the batteries. Once chrged from the sun I switch back to running just on solar. I only open the breaker to the Multi if I want to charge the batteries from the grid.
This process is completely unnecessary when you configure the ess assistant. It does exactly this what you do by hand. Also you can set the minimum state of charge of the battery very comfortable in the VRM Portal so that you have enough energy for emergencies. With the Multiplus you have an excellent system but you don't use the good things of it.
@@shadowpv2498 I have not used the ESS assistent yet. I do not want to export energy to the grid, and I also do not want to charge from the grid either. Is it possible with ESS to run through the inverter without charging my batteries when SOC goes down to say 15% and then automatically switch back to battery power when SOC rises to a higher level? My issue is that if I control the system manually I can alread start to use the battery if I know there will be a sunny day tomorrow. If It works automatically it will often be lots of wasted energy as I am not able to use power as quickly as the solar panels will geberate it
ESS tries to level the grid consumption and feed in to zero. So the batteries will be charged when there is excess and discharged when you consume more then the PV is delivering. When it reaches minimum SOC it stops discharging and takes the energy from the grid. If you want to feed into the grid (or not) in case of a full battery can be chosen by setting a switch in the menu. Changing the minimum SOC by PV Forecast of the next day can also be achieved, but this is much more difficult. For this you need some skills in NodeRed and some custom logic. But you can set the minimum SOC very easy by hand in the ess menu if you want to. Also the battery will only be charged from the grid if the soc is very low to prevent damage for the battery
@@shadowpv2498 vielen Dank furs info. Muss ich dann mit ESS rumspielen! I just don't want to upset the system by doing something wrong now I have it working well. NodeRed and custom logic are something I have never heard off so I don't think I will be playing with them any time soon ;-)
@@shadowpv2498 hi Helmut. I wanted to say thank you for your replies. Because of this I was confident enough to install the ESS assistant and am now running the system as you suggest in the video. So far OK, but I may have some questions in future about optimising the set up if you were happy to answer them? Mark
Thank you for the explanation!!!
Why don't they just make cables that are ready to plug in . Making those Lan cables seem intimidating
You can buy them but are expensive and often not in the right length.
Sorry wrote from my german channel. You can buy them here: www.panda-solar.de/VE-Can-zu-CAN-Bus-BMS-Kabel-Typ-A-1-8m.html
If you have only multipluses (no other inverters) AND everything/all loads in your house goes through your multipluses you don’t need the em24, the Multipluses will then know/measure everything.
Yes you are right. One downside is that the VRM statistics are not very accurate then because there is a bug in counting
Hi, thank you very much for your video explanation. I would like to know if it can be designed a ESS solution with zero feed-in feature and solar power only on the DC side. Best regards
Yes this works without problems. Just built it as shown in the video.
You need a Current Transformer device to implement that.
could you record a video? batteri pylontech 3000c multiplus 2, how to set charging and discharging parameters. and how to set DIP switch?
You don't realy need to do this settings by your own, because they are transfered via the communication to cerbo gx. Perhaps I will show this in a later video
so is it necessary? or is there another way to set the necessary power the multiplus has to provide?
If you have 3 Multiplus and all loads on AC Out you don't need the EM24, it has only some problems in the statistic in the VRM Portal, but the ESS System is working. When using 1 or 2 Multiplus or have loads between grid and Multiplus the EM24 is necessary
@@shadowpv2498 Thanks for the answer, my question actually was if one could use a different method of providing the info the Multiplus is requesting from the EM24 for example like with the shelly you pointed out in one of your videos, or other smart meters since the EM24 is currently quite expensive. Nevertheless aparently it is possible but one needs to tinker around with the venusOS as far as I understood it.
very usefull indeed, thanks to cover this topic on english too
Thank you for your video. It helped me to get it right.

Interesting!
Thank you
Hi, great video. Do you know if you can use just one Pylon battery for an AC system and Multiplus II 3000VA?
Yes this is possible, but you won't get full charge/discharge rate of the Multiplus
Super erklärt, danke dir!
Very useful video Helmut. Will you still be doing the follow-up video on the Type A Cable?
Yes for sure!
Hello. Great video! Very detailed and goal oriented. In this setup what is the battery monitor that you select on the GX (settings->system setup->Battery monitor).? When i had only one battery i was using "multiplus on Ve-bus". Now that i have two batteries there is a big gap between the other option "pylontech battery on can-bus". White One (multiplus) gives me 30% available, the other (pylontech) gives me 50%. What should se use?
I think you should use the SOC of the Pylontech
Thanks a lot! This is exactly what I was looking for, since the Victron documentation states to use the VE-BUS with no mentioning of the BMS-CAN ports. I only have one additional question: I plan on having two strings of 6 Pylontech batteries, let's call them Bank A and Bank B. I assume to use both BMS-CAN ports, one for Bank A and the other for Bank B, hence making the Terminator plug opbsolete. Would this be correct?
I think this is wrong. The DC wiring is independent from the bus wiring. So from the bus perspective, it is only one bank and you need to connect Link port 1 of the last battery of bank 1 to Link port 0 of the first battery of bank 2. When you want to use more then 8 pylontechs there is the need for a pylontech hub.
@@shadowpv2498 My plan was to connect them to the Lynx Distributor with their own sets of - and + so they would operate as two independent banks.... If that makes a difference? 🤔
@@kasperholmj No there should be no difference. So you should be fine as described above.
@@SchattenPV okay! Thanks for the clarification!
