Extending a Pylontech battery from 4 US3000 to 4xUS3000 + 8xUS3000C using an LV-HUB. Connecting to Cerbo GX via BMS cable type B. So far not able to make the Cerbo see all 12 batteries (Total capacity and live currents) at the same time. I can get up to 8 batteries showing by eliminating the LV-HUB from the setup. I can also get 8 showing with the HUB but not 12.
I realise the LV-HUB comms set up is very different for US3000 and US3000C. Hence I have also tried to create 2 stacks of 4 3000C followed by 2 x 3000. This means each stack is limited to 6, and both stacks are using 3000C as master battery. No joy getting both stacks to show on the Cerbo. (Even though one stack does show)
Has anyone managed to mix US3000 and US3000C with a Cerbo GX in a single system ?
I'm out of options but still keen to be able to monitor and control charging as a single 12 battery system via Cerbo GX
Any hints / tips / suggestions welcomed,
Is there anyone who out can guide me through the Installation cerbo gx - pylontech lv-hub - 3 groups of us3000c via CAN Bus?
At present, I have one of the three battery groups communicating to Cerbo via VE.Can to CAN-bus BMS type A Cable, works fine.
Which are the right cables to link the battery groups with the LV-HUB, and where can I buy the right cables? Really from Pylontech? I found a Video that Shows that pin 1...3 are required and their trouble came from the cables...Pylontech didn't answer. The manuals of lv-hub and battery are contradicting...
Can I take the type A cable to link LV-HUB to Cerbo?
How about the DIP settings of Batteries and LV-HUB?
Given the difficulty of correctly configuring an LV HUB with GX and several clusters of US2000C/3000C, I thought it would be good to lay out our parameters that have been successfull with our Victron systems, after many trials and tribulations. LV HUB manual lacks clarity.
Hope this helps !
What cable do you use between the Pylontech LV hub and Cerbo GX. I am getting no comms using either of the Victron BMS Can cables (type A or B)
I have a system with 12 x US3000 batteries connected in series of 3 (4 banks) via an LV hub-CAN to a Cerbo GX device.
Initially, we had challenges with the LV hub staying connected to the Cerbo GX. After a few days of operation, the Cerbo GX would no longer see the batteries and the inverter (8000va/48V) x 2 connected in parallel would shut down. We fixed this by updating the firmware of the LV-hub to V1.7.
Now we observed that the system is stable in off-grid mode. I.E. No active grid connected. but when the grid is active the after a few minutes the GX will lose connection with the batteries and the inverter and charge controller will shut down as a precaution.
Has anyone experienced this before, kindly advise on what the issue might be? See full system specs below
Pylontech - US3000 x 12
Victron 8000va/48/230 x 2 (parallel)

400W units of PV modules x 35
Hi all. I have an off grid set up with a victron 48/15000. Up till now I had a single stack of pylontech batteries and everything functioned fine.
When adding a second stack and wiring up the LV hub to both stacks, the hub keeps getting a red flashing light error. The dip switches are correct and all wiring is perfectly done.
Each stack connected independently works fine but when put both through the hub they don't work. The error is also present if the hub is not connected to the colour controller. Does anyone have any ideas?
The sellers puntoenergija have no idea. Not much documentation online either. Pity cause pylontech batteries are very good quality.
System - Single phase - 2x 5kw Multis in parallel.
2x stacks of 5 Pylon US2000 in parallel with LV-Hub
It would appear that the LV-Hub doesnt correctly report the correct available charge / discharge current to the GX.
The GX is showing 125A. (which follows the 5x25A mentioned in this doc:
It should report 250A ?
The LV-Hub, also does not correctly report the operating charge / discharge current the the batteries into the system. (Noticed this as we also have a BMV in the system)
the question is, how to connect a Pylontech HUB to Pylontech US2000B on one end and with the other end to a Multiplus-II? The problem is, that there is no documentation on the Pylontech website available which fits to the delivered LV-HUB and all suspects I know, doesn't have an idea.
Here is a screenshot of Pylontech PDF
there is mentioned that maximum 5 battery strings are possible, but my hub looks like this ...
... my hub has eight CAN-Bus connectors. I don't have any idea how a CAN-Bus cable looks like? Is just a normal network cable? I am willing to try, but without any input it is hard to start.
Hopefully there is somebody out there, who can set me on to the right trail! ;-) Thanks!
