Pylontech

Its not clear if the the Victron guide https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom#minimum_battery_sizing_recommendations applies both to the US 2000 and US 3000 models . The US3000 model is 50% larger yet it seems from the guide that the minimum number of modules are same for both US2000/3000. The article title says US 2000 / 3000 however the paragraph showing the minimum battery size only mentions the US 2000 model

I run a Quatro 48/5000/70 2x100 product id 2658 firmware 4.24 device 257 with CCGX version 2.33. I just installed three Pylontech US 3000 batteries, I configured exactly as per setup page on victron site but Quatro refuses to start up , Mains and battery low light flashes and CCGX display Pylontech Batteries at 67% charge and 49.6V with charge current limit at 111A

Quatro refuses to move from Charge only, not even from CCGX or manual switch. Please help.

Hi,

I would be grateful if someone could tell me what is the thickness of the Pylontech extra long cables are.

Many Thanks

Tony

I'm considering getting a set of 4 Pylon batterys for my Multiplus 5000/48V . I have a Venus GX device and am wondering if you have visibility to the internal temperatures of the Pylontech batteries ( either globally or individually ) and do you have individual SOC values for each of the batteries ? Can you add more than 1 string ( each up to 8 batteries )of Pylonbatteries to a Multiplus/ Venus system all being controlled via CAN-BUS

Hello folks!

I'm studying an Off-grid system to be installed in a mountain house, which will be mainly used during the weekends.

I'd like to ask you some advices on the equipment I selected:

Item	Qty
MultiPlus II 3000VA 48V 2400W	1
2.4kWh 48V Pylontech US2000 Battery	1*
300W solar panels	4*
MPPT BlueSolar 150/35	1
Control Venus GX	1

* Qty may be expanded in the future

My questions is: will my system work? Is the selected equipment compatible?

Is there anything to correct / improve?

Thanks a lot! Any suggestion is welcome.

Matteo

When using the Quattro with PylonTech CAN bus controlled batteries do I need to connect the voltage and temperature sensors to the Quattro, or will it get the info it need from the PylonTech?

Good day

When setting up a Quattro with an ccgx and pylontech us3000's what settings need to be changed on the Quattro except for the basic voltage settings ?

This system will be off-grid and power will be supplied with 2 250/100 mppt's that are connected to the ccgx with Ve.direct and Dvcc will be set up. There will be 8 us3000's with one Quattro 48/10000.

Hi,

it would be nice, the everyone can choose if he would use the limiting to 52.2 Volt when using Pylontech batteries or not. A simple switch to yes/no would be nice.

See: https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom#my_system_only_charges_the_battery_to_52v

Dear Community,

i am using MultiPlus II with Pylontech Battery and SmartSolar managed by VenusGX.

ESS is configured with phase compensation and everythin is working perfectly. But the maximum compensation is much lower than i expected (See picture). In maximum the batty is used with approx 17 Amp. I thought the maximum would be around 25 Amp. Any idea why it is not going above 18Amp?

Thanks a lot!

Hi all,

Finally thought I had my system sorted only to find it won't stop charging! Currently I have no PV so just charging off peak on the grid. I have followed the instructions for the Plyontech setup here:

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

And all seemed to be ok until I found the batteries are being charged all the time, right up to 100% and then beyond, setting off high voltage alarms. I just don't understand why it is doing this. I've gone through the ESS assistant, set the various voltage levels etc.

Absorption voltage 53.2 V

Float voltage 53.0 V

Double checked the communication cables, the BMS -> Inverter cable is the correct one and the right way around. I've told it to use the Pylontech BMS. Then I've set a schedule to charge from the grid between midnight and 4am. But actually, the charger just sits in bulk mode most of the time, pushing a small amount of current to the battery. Later switching to absorption. This is all outside of my midnight - 4am window. When that comes around, it ramps up the current to something like 2000W and also continues beyond the SOC limit of 95%?!

Pictures below. As you can see, it goes to 100% and up to 54v despite being told not to. I initially had Optimised with batterylife but thought that might be it, so am now on Optimised without batterylife, but no change.

I have to turn off the AC in connection manually to get it to stop!

Any ideas please? Thanks.

[image]

No grid meter, AC input = grid, Pylontech BMS. Cable is set to 500 CAN. DVCC set to on.

[image]

Midnight - 4AM charging only

[image]

Voltage above 53.2 and still going...

[image]

Charges right up to 100% and continues until the Pylontech BMS shuts off at 54v after trigging high voltage alarms.

[image]

Charge limit set to 53.2v. Completely ignored.

[image]

Ran down the battery. Then switched AC IN on and it starts charging immediately from the grid, albeit slowly, outside of the scheduled charging window.

Why would it always be in bulk or absorption mode, all the time? Why not idle, or off?

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

After commissioning the system according to the documentation here:

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

the GX display does not seem to be displaying correctly the battery state of charge (%). From an initial value of 100%, the % is decreasing daily, despite all 6 green LEDs being lit up on the Pylontech batteries, indicating 100% SOC. There are very few loads on the system at present and plenty of solar available for charging. Could the monitoring system be only measuring discharge currents and not taking account of charging currents? Could there be a communication issue between the GX and the integrated SmartSolar charger?

Thanks,

James

Hi,

I'm thinking of getting 8 Pylontech US2000 Modules. They will be in 2 banks of 4. I will also be geting a Venus GX.

Do the Pylontech have the same problem as some other lithium batteries with the SOC being inaccurate at load loads? Is there be any benefit to having a BMV-712 with the Pylontechs?

Many thanks

Tony

Good day all.

my local supplier is requesting some values before a warranty for the Pylontech batteries can be activated. The problem is that the values relate to Voltronic inverters and I have Easysolar inverters (Victron Multiplus). Can someone please assist me in where to get the corresponding values with my Easysolar:

Program 02: Max charging current Bulk charging voltage (C.V. voltage)

Program 05: Battery type Floating charge voltage

Program 12: Setting voltage point back to utility source Battery cut-off discharging voltage when grid is available

Program 13: setting voltage point back to battery mode Battery re-discharging voltage when grid is available

Program 26: Bulk charging voltage (C.V. voltage) Battery cut-off discharging voltage when grid is unavailable

Program 29: Low DC cut-off voltage

Can someone also tell me if I must still obtain a local warranty from my supplier even though I have filled in the Pylontech "sign up battery" section for the warranty and have received an official registration number?

thank you in advance and kind regards

Hi,

Little confused about battery wire requirements and fuses for using the Multiplus II with Pylontech batteries. It would seem that you have to use Pylontech branded cables as the batteries have a proprietary connector on one end to go into the battery. I can see in the manual it recommends 35mm2 cable and a 125A fuse. My dealer gave me a 200A fuse, I read on here, someone else had their distributor give them an 80A fuse. Confusion number one!

Confusion number two, I can't see what the cables provided by Pylontech are in terms of thickness, there doesn't seem to be a rating on them. But like I say, they have a special connector on them so it would seem you have to use them? Confusion number two!

https://www.ebay.co.uk/itm/2m-Long-Cable-set-Pack-Pylon-PylonTech-US2000-Plus-US3000-Phantom-Solar-Battery/253792544671

Then finally, I have seen two installers here in the UK, who don't have a breaker, isolator or fuse on their installs between inverter and battery. Mind you, one of them also puts the batteries below the inverter, which the manual pretty clearly says not to do! Confusion number three! See pics.

Any help advice, particularly from someone who has Pylontech batteries would be much appreciated.

Many thanks,

Gareth.

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

Pure DC system with 3500w PV and

VenusGX (2.33)

SmartSolar Charger MPPT 250/100 rev2 (1.42)

BMV-712 Smart (4.01)

Pylontech US2000B.

512 = Pylontech
260 = BMV-712 Smart

[image]

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,

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?

[image]

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
