Pylontech

Hello,

I have the following equipment installed:

1 x Quattro 48/8000 230V

2 x MPPT Smart Charge Controllers 250/100 MC4

8 x Pylontech US2000B Batteries

1 x Venus GX

The batteries are connected to the Venus through one Can port using the VE Can Cable Type B and the dummy plug is inserted in the other port. However, the Venus isn't recognising the Pylontech, it isn't shown in either the device list for the installation (usually shown under battery monitor) or in the device list section of the remote console.

Can-bus profile is set to Can-Bus BMS (500 kbit/s) and DVCC is enabled. Venus is on firmware 2.31 and Quattro is on 459.

Battery monitor under System Setup is set to Automatic but it appears to have auto selected the Quattro on VE Bus and the BMS is set as Off and doesn't give me the option to change it.

Please help me to enable the Pylontech BMS to act as the battery monitor.

Thanks

I have 4 pylontech UP2500 connected to a VENUS GX and Smartsolart MPPT 150/60. On Victron connect I see a battery percentage on the top level but no battery appearing on the device list. The Smartsolar does appear, as does the Multiplus 5000 inverter. should the battries connect to the Venus GX via the Victron CanBus BMS TYPE B cable or should the batteries connect directly to the inverter using this cable? Help please.

Dear @Daniël Boekel (Victron Energy Staff)

Recently I noticed that you changed the DC input disconnect voltage to 44V

LINK VICTRON LIVE

Pylontech manual says limit discharge voltage is 44,5V

Would it be safe? Why did you make this change?

Best wishes,

Daniel.

Hi

I am trying to understand how cold weather will affect the system.

Venus GX
SmartSolar 250/100
BMV-712 Smart
Smart BatteryProtect 48v-100A
2 Pylontech US2000

How will the system behave if cold for the battery to charge or discharge. I assume that the BMS will tell the Venus GX that in turn controls the SmartSolar to stop charging the battery.

So down to my question, will we still be able to run DC loads direct from the SmartSolar that is connected in parallel to the battery (when the sun shines of course) without this conflicting with the battery charge or discharge?

Or will all power from the SmartSolar be stopped?

Hello to all,

this is the first time that i use pylontech batteries.

I build a system from 5 US2000 Plus Batteries, a MultiPlus 48/5000/70 and a Color Control.

There are two things that i don`t understand and i hope you can help me.

I charge the battery with the recommended absorption voltage from 53,2V. I get from the battery the warning "Voltage to high". I reduce this voltage step by strep from 53,2 V to last test of 51,8 V. But i get in every absorption phase the warning "Voltage to high". The datasheet from pylontech shows a value from max 53,5V.

Because of this error message i write to Pylontech, but i get no answer.

The other thing is a little funny.

When the battery is discharge and i start to load the battery, the load voltage and current are like the bulk phase but the MultiPlus shows at the LED float. I switch the Multi off and on again, the charge starts with the same voltage and current but the LED shows bulk.

Did you have any idea whats is the cause and i can do?

When you need more information to help, i can give.

Many thanks in advance.

Hello,

my working configuration (id 5041) was
Quattro 5000/48
Color GX
4 Pylontech US2000B PLUS modules
Energy Meter EM24

All single phase, works as off-grid, solar inverters are connected on AC-out.
All worked marvelously, all systems showed up as they should on ColorGX.

Now, 4 Us2000B modules most of the times works jst fine through the night, but sometimes not.
With some extra money at my disposal I bought 4 units more, which are now are labeled US2000, as of July 2019 the US2000B PLUS changes name (and only name as per pylontech statement 0709).

I connected the new ones first, but the battery did not show up on the Color GX.
When I connected one US2000B PLUS first it showed up, but the ColorGX did reset values constantly, and charge limit was set to 25A.
Then I connected the 4 old modules first and the new modules last.
Charge limit was now 95A (meanwhile it is 100A), as per 4 modules.

The 8 modules do wake up as "one", the LED from the modules all show up like they should and looks nice.
But Color GX display showed constant "values reset", as if it constantly re-ready the values from Quattro/battery/amperemeter.
I switched off DVCC, since then display is calm again, showing values from Quattro, Battery and solar inverters.

But Color GX still says 100A charge limit, and I have the feeling it sees only 4 modules.
Someone had the same issue ? What else can I check/change/try ?

Thanks
Guillermo

PS
I forgot to tell that after a few days all batteries were levelled.
And capacity-wise it looks as if all batteries are present.
So the batteries are working but it seems that the new ones do not communicate with ColorGX,

Hi

After remotely from VRM upgrading SmartSolar to 1.42 my battery doesn’t get charged fully. It charges to example at 92% and today 89% and then just stops and only matches the solar yield to the DC consumption even when there is lots of sun.

I got an error “#68 Network misconfigured” from the SmartSolar after upgrade so I had to exclude it from the SmartNetwork. That is clearly show on the graphs as the big dip starting 2019-04-24.

Both times it has got back to SOC 99 or 100% was after a shutdown and power off whole system and starting it up again.

I have notice the BMV-712 in not correct in SQC and stated 100% when the battery is not. But the VenusGX is set to use Battery Monitor “Pylontech battery on CAN-bus”. Can it be the BMV that is still being in control of SOC in some way? SmartSolar is disconnected from the SmartNetwork but it still feels like it stops charging when BMV get near 100%

The system has been working very good until now.

I have checked the settings against https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

This is a remote location and I can only use VRM unless I take the trip there.

Is it possible to use Pylontech batteries with mppt + venusGX + phoenix inverter for an offgrid application?

Do I need to use a multiplus instead?

We have added a US 3000 Pylontech battery module to an existing bank of 5 US 3000s. On completing the installation and switching on - all battery modules are operating normally and the system itself is operating normally with no faults showing. the battery monitor however is showing the fault;

[image]

this alarm has been active now for 24 hours. what is the reason and how do I rectify it. I suspect it is a result of and arc when closing the fuse to the inverter - but as i say the alarm is still active.

The system consists of;

1 x 8KvA Quattro

2 x 150v 70A controllers

1 x venus GX

6 x Pylontech 3500 - set up in two strings of three

24 x 335w solar modules

Hello everyone,

My system consists of:
3x Multigrid
1x CCGX (currently not functioning)
6x Pylontech US2000Plus

As my CCGX is currently not functioning, I would like to know the battery's SOC by listening to its CAN broadcast using Vehicle Network Toolbox in MATLAB-Simulink. I have also read that the SOC can be determined using BatteryView software. I have the software, but I don't have the USB-RJ11 cable to connect the PC with the console port on Pylontech.

Questions:

1. Is the above mentioned communication with MATLAB possible? Actually I want to use MATLAB not only to read the SOC but also to process other data from the battery (university project).

2. Are there any alternative ways to read the SOC without using CCGX and BatteryView?

3. Are there any documents/datasheets available regarding CAN communication protocol of Multigrid and/or Pylontech battery?

Thank you very much.

Hello,

My system consists of:

3 Multigrid 48/3000/35
1 Color Control GX
6 Pylontech US2000 Plus batteries

The Multigrid are installed for three-phase system out of the AC-OUT port.

I have followed the instructions from this documentation until including step 3:
https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

I want to continue with the configuration (step 4), but all three Multigrid did not start (i.e. none of the LEDs blink) after I switched them on. Note that a grid voltage of 230V can be measured at the AC-IN ports of the Multigrid.

What is causing this problem and how could it be solved? I would appreciate any help!

Thank you very much.

3kVA Multi; Venus GX; 3 x 2.4kWh PylonTech's and 3.96kW PV in ESS mode with feed-in allowed and 'Keep batteries charged'. DVCC on as should be, 2.31 Venus firmware and all other firmware no later than 3 months. Battery voltage rapidly drops to below 50V and SOC progressively during night from 99% to 94% in early morning just before sunrise. Is this normal? If not, how do I correct?

I have the above inverter with Rolls 5000 6CS25P batteries (supported with PV panels) which are 14 years old and have done great job. I am thinking of replacing them with Pylontech UP2500 24v batteries but cannot find any confirmation that they are OK with Multiplus as above. All advertising notes them as suitable for backup or UPS but not for daily cycle solar power. My alternative is to get a new 48v Multiplus, which would be a shame as this one is only 3 years old, with the Pylontech US2000B or US3000B batteries. Any thoughts much appreciated.

Hi there,

I am in the process of designing a small UPS setup based on Plyontech battery modules.
I basically just need a small inverter and a charger, with the possibility to add a solar charger at some point down the road. To get started I'd like to combine a MultiPlus 48 inverter/charger with a Venus GX. Will this work? Is there any way I can get away without requiring the Venus GX?

I'd appreciate any help!

Cheers

Mat

Good Day

I have a PYLONTECH 8kw 48V battery setup with a Victron Multiplus on ESS, connected to Solar.

One issue I have is that when the mains supply fails and am running on batteries at night, I cannot limit the level of discharge (batteries discharge below 80%).

I tried adjusting the dc input low shutdown on the Multiplus but did not work.

Please advise. I would to limit the battery to lowest 85% discharge level.

I have Pylon batteries connected to my MultiPlus-II 48/5000.

The batteries are fully charge at 53V and I did set the MultPlus-II settings as stated in the Victron & Pylontech US2000B Manual, VEConfigure Settings.

The Multi Battery LOW RED LED is flashing and if I disconnect main, the Multi switch off after 30 seconds because of low battery even if the battery is still 53V.

What am i missing??

Hello,

I have a system consisting of the following (1) Venus GX, (4) 10 KVA Quattros, (3) Fronius 8.2 kW Primo inverters (connected on the AC-Out) and (24) Pylontech US2000B batteries (4 piles of 6 batteries connected via the LV Hub to the Can Port).

The system constantly switches the "Mains" off whenever the load on AC-Out 1 spikes. It goes into "Inverting" mode and acts as if the grid has failed even though power remains at the AC-In line. As a result, the ESS function ignores the Battery Optimise SOC limit and draws all power from the batteries causing a low battery alarm and shutting off the system entirely. This basically creates a "power cut" at the site which is easily rectified by flipping the bypass switch and allowing the grid to flow directly to the house as if the system was not installed.

This can not be how the system is intended to operate. What can be causing this to happen?

Thanks.

I have the above system with the Pylontech batteries as the latest upgrade due to failure of Deltech Lead crystal batteries. It seems that the Blue Solar MPPT chargers are communicating at the 250bit Baud rate and the rest must now communicate at the 500bit Baud rate.

Current workaround is to set the Quatro as the BMS and have the rest of the system at the 250bit which is not perfect.

What is the most cost effective solution?

Hi There,

This might be quite elementary to solve, however I keep getting high voltage alarms from the Pylontech battery at times of high solar yield.

What can be done to solve the problem. The alarms tend to show up at voltages below the recommended charge voltage settings, ie max voltage for absorption charging 53.2V and Float 53V in accordance with the manual.

I have downloaded logs for some of the alarm events, these can be found at the following link.

https://drive.google.com/open?id=19c45KZUPvGrVP4q_MgFSeSdjDPtzZu3r

Where could the alarm be triggered and why, and how could the setup/settings be changed to avoid or reduce the alarm event. At present it is a once a week occurrence.

Best Regards

Riaan

Hi there

I have 4x3.5kWh Pylontech batteries, and they perform very well. This is more or less 280Ah @48V.

On a number of occasions, I have seen the SOC remain at 88% as per the Venus remote console, even when charging at 30-40A (28A is about the C10 rate). Charging at 28A should result in SOC moving up by about 10%/hour or 1% every 6 minutes (more or less).

But SOC never goes above 88% that day. I have observed reported battery volt go up from 50.8 to 50.9 to 51.2, but the SOC remains at 88%. It only ever gets "stuck" at this specific 88% SOC. IIRC 51.2 is about 95%.

Since the battery voltage does go up, I assume the batteries are charging (they are accepting the current). Is this perhaps an SOC algorithm/BMS issue?

I have not been able to test if they stay at 88% longer as well when they start to discharge at the end of the day.

We have multiple pylontech batteries that never ridge float state and the BMS always report 99% charged. It jump between charging/discharging and never get to a state where it float.

It's in an backup system and setting have been confirmed as per Victron guide for the Pylontech.

Hi,

on Pylontech Page is written, that only Shared Voltage Sense (SVS) has to be turned off. (https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom#venus-device_settings)

[image]

On Color GX Page SVS and STS has to be off. (https://www.victronenergy.com/live/ccgx:start#introduction_and_features)

[image]

If i disable STS, the Multiplus will get the wrong battery temperature. This can be shown via Modbus or VRM. If i enable STS, the Multiplus shows the same Temperate as Pylontech BMS is reporting.

Now i have set it like this:

[image]

What is the correct STS setting?

Thanks a lot!

Dear Victron lovers,

I read about strange behavior in Pylontech + Victron systems with DVCC enabled.

My GX device shows that firmware version in the solar charge controller must be v1.29 to work with DVCC enabled.

But the latest firmware version is v1.37

What firmware version should i use in order to achieve the dvcc works properly?

We have just installed 12 x pylontech US3000 with a hub for 2 racks of 6. The BMS is correctly communicating the DCL, but not the CCL. The CCL and DCL should be equal and the CCL is exactly half that of the DCL, which makes me believe that the BMS is only communication the CCL of one rack, not both. (cant be temperature issue as we are at 30ºC here)

This poses quite a problem. I have already noted that, although the Pylontech website and suppliers say that the US3000 can go up to 12 batteries without a hub, this isnt the case. If you do this, only 8 will be recognised by the Master (exactly the same as the other models). Therefore a hub is required.

I hope this CCL issue isnt another error!! Has anyone else heard of this issue? Is there a work-around?

Thanks

Hello,

I have a system composed of:

3 Multiplus II 48/3000/35
1 Color Control GX
1 grid-tide three-phase 6kW inverter
12 Pylontech US2000 batteries
1 Pylontech LV-hub

The Multiplus II are configured as a three-phase system and the grid-tied inverter connected to the AC-OUT 1.

The pylontech batteries are connected in two groups of 6 pylontech batteries and them to the LV-hub, according to the instructions of pylontech.

I have follow all the instructions of the configuration recomended by Victron at:

https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

The Color Control has detected the Pylontech battery correctly and parameters are correctly shown in the Color Control display.

However, it has not been possible to start the system. The Multiplus II are displaying the "Low Battery" LED all the time and they do not generate any tension.

What is causing this problem and how could it be solved?

Thank you.

I have 4 Pylontech US2000B batteries. I added another 2, since then I cannot see them on my Venus Gx.

I removed the two new ones but it still doesn’t list?

Any suggestion?

Thanks

How do I get the Pylon Tech Battery to list under devices on my Venus GX?

The devices in the system.

1. MultiPlus-II 48/5000/70
2. Venus GX
3. SmartSolar 250/100
4. Pylon US2000B x5

I have the latest firmware on the Venus GX and the MultiPlus.

Should I change the baudrate on the pylontech battery?

Should I turn the batteries Off and back On after connecting to the Venus?

I did have the CANbus cable the wrong way round to start off but this is now fixed.

Any idea?

in my vrm.victronenery portal, under devices I don't see my battery/s (have 2 x Pylontech US2000 plus's) I am using the non Pylontech supplied cable. the Victron is getting comms/data from the batteries.

Do I connect the smart solar MPPT controller directly to my Pylontech us2000 battery or firstly to my Multiplus ii? If it’s the battery first where on the Pylontech do I do this as it’s already attached to the inverter via the customised Pylontech cables. Thank you.

Hi all

I can see 2 x Temperature sensors listed under Devices, but if I go remote Console, settings... then both shows disconnected, how do I get these configure/reporting.

assuming they are identified via the data cable thats configured between the VenusGX and Master Pylontech battery.
