Pylontech

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?

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.

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:

What is the correct STS setting?

Thanks a lot!

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

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.

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

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

Is this still that case as it its not possible at all or are there limitations?

I have a second inverter that I intend installing the Pylontech Lithium batteries

However, the bluesolar MPPT 150/85 charger does not have a VE direct port.

Is there a solution to connects via VE Can port to the CCGX such that it will work with the Pylontech?

So far all the information refers to connection via VE direct

I have 3 Pylontech US2000 Plus connected in parallel with a MultiPlus 48/3000/35 and a MPPT 150/45.

The CCL is set at 30A by the battery, is this because the MultiPlus can only charge with 35A and the battery knows this? I haven't connected the PV panels yet but when I do should I see this value raise to 75A as the MPPT can provide an extra 45A?

The DCL is set to 75A so I'm assuming that all 3 batteries are being detected and everything in the setup is fine. Any comments welcome please and thank you.

Hi all

Seem to have read that you need to tell the batteries who the master is and the slaves in the string,

For this to happen you flip the dip switches?

Can someone indicate what the master should be set to and the slaves?

thanks

I have some questions about a Pylontech setup.

Today I have the following, (not yet installed):

1 Pylontech US2000

1 Venus GX

1 Venus GX Temperature Sensor

1 BMV-712

1 SmartSolar MPPT 250/100

1 Orion-TR 48/12-9

The battery will sometimes be below the temperature for charging and I want to make sure that it will not get charged then.

Do the BMV add any value and more features than just using the Pylontech BMS with Venus GX?

If I do need this can I use the Venus GX temperature sensor, will that send the temperature to the MPPT?

I have installed a Victron Easy Solar 5000 with two Pylontech US3000 batteries and 12x330 canadian solar panels.

In the beginning the system produced up to 3800 w of power but is seems the installer limited the PV to first 1600 w and then to 2600W.

What would be the reason be for this , since I need more PV for my house at midday.

When I asked the installer his reply was that I need to install more batteries then he can "open up" the system. This seems to me not right.

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.

Setup:

Victron Multi Plus 48/3000

Color Control

2 x Pylontech 2000 Batteries

Smart Solar 150/35

I configured my Setup with the help of this victron offical tutorial https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

Problem:

Multi Plus shows always "Battery low voltage" warning.

Question:

What could i have done wrong ?

Thanks for the support

Hello,

in the Victron product compatibility-list the pylontech batteries are listed to only can be used in an ESS-system. I think this is necessary of the CAN.Bus-Communication. This means that communication only works with the ESS assistant (why)?

I have to wait further 6 months for grid-connection to be built. For that time I want to build a small DC-Coupled PV and a Multiplus with Pylontech-Batteries. A big AC-coupled 30kWp-PV will follow next year. Since I wanted to install a Victron-ESS anyway I am wondering if I could use the pylontech also in an offgrid installation until the grid is ready?
Alternatively I wanted to install the ESS-Assistant offgrid and hoped i can use the pylontech without discharging them to 0% when grid isn't available at no time. I also don't know if a generator would be accepted in the AC-In then when a grid code has to be chosen.

I red that ESS shouldn't be used in an offgrid-installation neither. I know that ESS doesn't make sense in that situation, but it has du be used to use the pylontechs?
So is there a solution to use these components until grid will be available?

Thank you!

I`ve got an problem with DVCC on while charging the batteries. My system: Multigrid 48/3000/35-50 with Venus GX and two connected Pylontech US2000 Plus. A BlueSolar 150/35 is DC- connected to the Multigrid. My Fronius Primo 3.0-1 is AC- connected to the output 1 of the Multigrid. The gridmeter is an ET340. The system work fine. But if i activate DVCC the charging current will slow down to about 20A and the excess of energy is load to the grid. If i deactivate DVCC the full energy (about 30A) is load to the batteries. I want to load all the energy to the batteries. All firmware is up to date. Whats the problem?

Hello, I have Pylontech US2000 unit and I want to connect the VENUS GX via the CAN-Bus-cable to the Pylontech unit for the following purposes

- See the charging Level of the Pylontech via Internet (Victron Cloud)

- use the Venus for switching relais according the charging state/Level of the Pylontech for at least one external load

- is it possible to switch more than load according to the charging state (eg. Load 1 at 50% load , load 2 at 70% load??)

I`ve got an question about gridfailure and disabled Fronius PV- Inverter AC1- coupled.

My system: Multigrid 48/3000/35-50 with Venus GX and two connected Pylontech US2000 Plus. A BlueSolar 150/35 is DC- connected to the Multigrid. My Fronius Primo 3.0-1 is AC-1 connected to the output 1 of the Multigrid. The gridmeter is an ET340. All firmwares are up to date.

Today our grid in the village is running at APU by the energy supplier because of repair. They`re setting up the grid frequency to 51,7Hz for turning off all the PV`s in the village. The Multigrid detect a grid failure and disconnected to grid. At AC-1 output the frequency is 53,0Hz and the Fronius is switched off. Shouldn`t it use the Fronius energy to charge the batteries by Multigrids internal charger? What`s the reason of this reaction?

Strange Voltage Values and Cut Off ESS System (Multiplus, Pylontech, Smart Solar)

Hello Community,

Setup:

Victron Multi Plus 48/3000

Color Control

2 x Pylontech 2000 Batteries

Smart Solar 150/35

Im using 35mm^2 Cables with a length of 1m. The temperature is 15°C.

I configured my Setup with the help of this victron offical tutorial https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

Problem:

Multi Plus shows often the "Battery low voltage" warning. Especially when I have higher loads the Battery Voltage drops and the Multi Plus cuts off the batteries.

Also very strange --> Smart Solar and Pylontech BMS show both the same voltage, but Multiplus shows a different voltage value.

This setup worked for over month pretty well, but since 5 days there are these mentioned problems and the battery voltages "fluctuates".

I tried so far to reset the batteries and to program the MultiPlus / ESS again. I thought maybe its better to set the dynamic cut off values in an other way than from Victron suggested, but I don't think this would help, because sometimes the battery voltage drops to 42,7V.

Question:

What could i have done wrong ?
