Hello, considering extension of system composed from MPPT 450/100, Multiplus II GX 5000 and Pylontech US5000. Due to Pylontech I need run Ve.CAN bus at 500kb/s which pushes me to connect MPPT by VE.Direct.
Speciffic matters of my instalation are requirement to avoid to distribution to grid (AC ignore on virtual switch), keeping Pylontech waranty (system is driven by Pylontech BMS).
1.) Lets consider I want to add some more MPPT 450/100 .. is it possible just to connect MPPTs together by VE.Can and let one of them connected to GX by VE.Direct or I shall use VE.Direct-USB cable for each such MPPT? If the second option is only suitable, how many additional MPPTs can I connect by USB adaptors?
2.) For purpose of additional Multiplus II (no GX) units I suppose connectivity by VE.Bus, right?
3.) Is that possible to run two Multiplus II with different phases on AC in with decoupled AC out? Nothing like rotating electric field on the output required.. only AC ignore on virtual switch (it s AC IN phases load optimisation).
Tq for resposne, Jakub
I'm having a hard time finding a minimum bend radius listed for the ve.direct cables in any documentation. The installation I'm working on uses some 2x2 inch (51mm) wire trough and some 2x1 inch. The ve.direct cables are all too long for the raceway runs (using shortest possible lengths) so I'd like to coil up the excess inside that trough, but am concerned about damaging it. Does anyone know the limit or have experience with either successful tight coils or with damaging them by coiling too tightly?
I have 2 MPPT 250/100 solar chargers that have been connected to our CCGX for 2 years. Yesterday, they suddenly were "unconnected." They're still working and charging batteries and I can connect to them via VictronConnect over Bluetooth. Both MPPTs were "last seen" at the same time which implies a common cause.
I've tried unplugging and re-plugging the VE Direct cables on the CCGX and the MPPTs but didn't help.
I don't have any way to get a new cable (if that's the issue) for a couple months. Thought I should check here to see if anyone has any other ideas?
Hello. Pretty new to Node-red here so i don't know if it's my fault. 2 days ago i had vedirect node installed just adding it with palette manager and i was able to connect to the device. Now i can't even add the contrib to Node-red. It installs but then it says a module is missing.

Hi, I am looking to connect a blue solar mppt with an esp32 via the serial connection. I have an octocoupler for this. The Mppt is on my boat and I can't test. I know that the masses are important without isolating via a usb-rs232. It didn't work without connecting the ground. Is it good like this? Or should the two masses be connected?
I have an RS smart 48/6000 (https://www.victronenergy.fr/inverters/inverter-rs-smart-solar), I want to communicate via the Ve.direct port with a homemade card (AtXmega).
I saw the protocol docs (VE.Direct-BlueSolar-HEX-protocol and VE.Direct-HEX-Protocol-Phoenix-Inverter) but couldn't find the protocol for RS Smart solar...?
Thanks in advance,
I have the mppt 100/30 and it stopped working after disconnecting the battery's.
I got battery voltage 25v on the input.
9v solar input.
When i disconnect the solar panels the leds are all off.
I cannot acces trough ve direct. It foes not discover the mppt.
What should i do?
Will VE.Smart networking ever be available for the IP65 Blue Smart Charger at some point?
So i have an older mppt running firmware 1.07 victronconnect won't see it, (ve.direct mk3 to usb cable) but via serial connect i get a response:
Checksum manf Victron Energy prod MPPT 12..24V/15A ser# HQ1302XWRZ9 ver# 1.07
How can i update it there must be away to directly upload via serial or hell maybe even via rom reader directly on the chip. these device's used to be updated via older software what that is i have no clue but without access i can't configure it so its rather important i can update it or atleast configure,
Just installed a Cerbo GX and Smart Shunt.
Powered everything on, and no smart shunt on the Cerbo. I do see it on bluetooth, so I updated the firmware. I have not yet tried a full power cycle. I did reboot the Cerbo a few times.
Not sure if related, but the Multiplus also did not show up on the cerbo. I connected that to VE Bus ethernet port. I plan to try a separate ethernet cable, also had trouble with MK3 to USB adapter to update firmware on Multi.
Was a crazy day. Any advice or trouble shooting ideas would be awesome!
System in my sailing boat:
I manage to control through VRM online portal the MPPT charger and the SmartShunt that are linked to Cerbo GX by Ve.Direct.
To control the Orion Tr Smart and the BSC IP22 charger that are not linked by Ve.Direct could perhaps be possible through an interface Bluetooth/Ve.Direct.
Does such an interface exist, or is technically difficult to build ?
Thanks for any answer !
I have a SmartSolar 150/35 and a MultiPlus II GX.
They are connected using a Victron VE.Direct cable.
The connection works, when it works. But it randomly drops out without any clear cause (no physical disturbance to the cable or connections, random times of day).
The charge controller and MP2GX continue to function but the PV information is no longer displayed by the MP2GX or on the VRM portal. This is very, very annoying as it makes it impossible for me to accurately monitor my generation vs my consumption.
I also use the VE.Direct to share the MP2GX temperature sensor data with the SmartSolar. I'm not sure whether this continues to work when the PV information stops being displayed.
To make them communicate again I have to turn the MP2GX off and on again, which is inconvenient. When I do this, VRM does not display the missing PV data for the period where they were not communicating, but they do start communicating again and VRM gets the live PV data once more...
Until they randomly stop communicating again, for no apparent reason.
I'm after any advice around this please.
Hello, looking for help to determine if the VE Direct port on my Smart Shunt is working.
The system is composed of a BYD battery with built-in battery monitor connected to a Cerbo GX BMS-CAN port and a Smart Solar 100/20 MPPT connected to the Cerbo GX VE Direct port.
Both the internal battery monitor and the MPPT report data to the Cerbo GX and everything is visible in VRM.
I wasn't happy with the accuracy of the internal battery monitor so I purchased a Smart Shunt and connected it to the Cerbo GX with a VE Direct cable.
The problem is that the Smart Shunt does not show up in the device list on the Cerbo GX. The Smart Shunt is operating and I can access it via bluetooth.
I swapped the VE Direct cables between the MPPT and the Smart Shunt and swapped VE Direct ports on the Cerbo GX. The MPPT will communicate with the Cerbo GX on any of the 3 VE Direct ports and with either VE Direct Cable but the Smart Shunt will not communicate with the Cerbo GX.
I'm thinking that the Smart Shunt VE Direct port is not operating but the unit is brand new and just out of the box so I thought that would be unlikely.
Could this have something to do with the Cerbo GX already having a battery monitor device configured and using the BMS-CAN port?
I currently have 2 * 150/60tr mppts on my solar system. They are connection via VE-direct ports (which the Venus GX only has 2 ports).
How can I go about adding another 1 or 2 150/60tr to the system?
is there no way to get them to sync using Bluetooth or something?
I need right angle VE Direct cables that bend away from the VE Can RJ45 connectors because my Cerbo GX needs to be routed in a tight spot below my Bilge switch. Wouldn’t it be better to give the customer a choice which way the angled connector goes?
