Pylontech

[image]

Ich möchte ein ESS-System aufbauen, und habe viel in Equipment investiert. Batterie ist wie hier beschrieben eingestellt. Das Venus GX erkennt das BMS des Pylontech US3000 nicht. Das Typ-B CAN to VE.Can habe ich mehrmals durchgemessen und entspricht der Beschreibung. CAN-Bus-BMS (500Kbit/s)

Der Testaubau sieht wie folgt aus:

[image]

Die beiden hellen RJ45-Kabel sind mit MK3-Konfigurator bzw. Internet verbunden.

Unter den Devices wird nur der Temperatur-Sensor angezeigt. Die Batterie fehlt und wird auch nicht geladen. Die Firmware vom Venus ist aktuell (2.42).

Über die CAN-Verbindung scheint die Batterie vom GX-Device nicht erkannt zu werden. Der MultiPlusII wird auch nicht angezeigt, obwohl mit UTP-RJ45 mit CAN-BUS verbunden.

Wie kann ich die Kommunikation zwischen PYLONTECH und Venus GX überprüfen? Gibt es Testtools mit dem MK3-USB-Connector?

Ist es richtig, dass das GX über den CAN Bus dem MultiPlus-II sagt, wenn die Batterie geladen werden soll? Die Konfiguration vom MultiPlus-II erkennt AC in, AC out und die Batteriespannung, aber geladen wird nicht.

Ist Vielleicht das Venus GX defekt? Ich bin nach 3 Tagen Suche schon total verzweifelt und kurz davor, alles wieder umzutauschen. Hat jemand eine Idee?

Viele Grüße

Hi all

I am currently running a non-Victron integrated MPPT/inverter together with 2x 3.5kWh Pylontechs and 9 panels. I have a Raspberry Pi solution in place that connects both to the inverter and the Pylon BMS and controls the inverter modes according to the BMS SOC (rather than voltage reading).

As the built-in MPPT is of older generation, I am now contemplating adding a Victron MPPT 250/85 to the system and moving my panels (and using my current unit purely as inverter).

What I do not fully understand yet is if I need to establish some form of communication between the Pylon BMS and the Victron MPPT? I've read about VE.Smart Networking but do not understand what the benefit of adding a BMV (or SmartSense) would be.

Can anyone here please help me understand?

Thanks in advance

Hi,

I am considering installing a Victron QUATTRO with Pylontech 48V batteries. I would initially purchase 4 batteries to give me around 12kWhr when new. I would like to later add another 4 batteries - maybe 5 years down the track.

I suspect that just paralleling the old and new would be a bad idea due to the original batteries having aged and lost capacity. It would seem better to have two separate battery banks and treat each separately for charging and discharging.

Is this possible?

If so, how would this be accomplished?

What would be the recommended way to add more batteries at a later stage?

thank you,

Ron

Hi Community, I hope I can post a battery-only question here :-) in Berlin there is an official PV storage subvention program - which has several conditions: one is 10 years warranty - I found a document that Pylontech does support this. Another pre-requisite is: the manufactorer is part of a battery take-back program (e.g. http://www.grs-batterien.de/) - means someone is going to take back the batteries after their lifetime. Does anybody know if Pylontech joins such a program at the moment? I put the german text in the PS part. Thank you Rainer PS. Rücknahme der Systeme Im Hinblick auf Ressourcenschonung und Reduzierung von Umweltauswirkungen der Speichersyste-me ist ein umfassendes Recycling von hoher Bedeutung. Um mögliche Umwelt- und Gesundheits-probleme zu vermeiden, sind insbesondere spezifische Kennzeichnungs- und Recyclinganforderungen entsprechend dem Batteriegesetz (BattG) zu beachten und die Beteiligung des Herstellers an einem geeigneten Rücknahmesystem nachzuweisen. Die Batterie muss nach BattG bei einem Rücknahmesystem (z.B. GRS Batterien) gemeldet sein. Der Nachweis kann vom Hersteller geliefert werden (Kopie der aktuellen Vereinbarung mit einem Rück-nahmesystem). Zudem müssen in Verkehr gebrachte Elektrogeräte (z.B. der Wechselrichter) bei der Stiftung ear registriert werden (Verzeichnis der registrierten Hersteller und registrierten Bevollmächtigten) und mit einer WEEE-Nummer5 belegt werden. Diese sollten auf jedem Datenblatt aufgeführt sein bzw. auf Wunsch vom Hersteller genannt werden können.

Hello All,

First time here on the forum. I am currently setting up my first Victron system and would require some direction on setting it up. I will list the equipment below first

1. Victron multiplus ii 48V 230V 5000W
2. Victron charge controller
3. 4x pylontech 2.4kwh
4. SMA 5000W grid tied
5. Carlo Gavazzi three phase grid meter

The aim of the setup is to use ESS feature of victron.

The SMA inverter will feedback power to the grid.

Charge controller will also feed back excess power to grid when batteries are fully charged.

Battery should only charge from excess PV power and not charge by import from the grid. very important

AC out 1 is connected to a critical load panel

All hardware is currently installed but would appreciate any feedback or direction in acheiving the objectives outlined above.

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??

How can I reset the VE.Bus or what else can I do to work make the CCGX/inverter work with DVCC and the BMS of the batteries?

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

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.

When using scheduled charging of my batteries overnight in the winter when the electricity tariff is cheaper and day time solar production isn't great, how efficient is the process of taking electricity from the grid and storing this in my Pylontec batteries, through the MultiPlus 48v, 3000VA, 35amp inverter? How much loss is there, 5%, 10%, 20%...? And a second part of the question, how efficient is the process to re-invert 48v back to 240v when I start using power from the batteries again?

It seems the electricity consumed from the grid for scheduled charging isn't recorded anywhere other than my mains electricity meter.

Thanks for any help.

James

But the batteries are charged

Configuration: Easysolar 3Kv (Multiplus 48/30000 + MPPT 150/70 + 2 Pylontech US2000plus as an offgrid system) I had it installed with BMS managed by the batteries (CAN.Bus/DVCC...)

One day I switshed the inverter off and after that I noticed that it doesn't start again Showing low battery :-0. Only if I connect the generator it comes back to live...

Just to see were I am I went back to first running setting: BMS automaticly managed by the MulitPlus ...deactivated the DVCC, CAN ect. (MPPT error #67, reseted MPPT) still no change.

In the VRM the low battery is displayed as VE.BUS error.

Any suggestion? THX

I want to build a 9,6 KWh storage with: Pylontec us2000 plus and Victron Multiplus 2 (3000 / 48 V) ... together with: Energy Meter ET340 and Color Control GX.

I'd get 300 Euro per KWh by a "city energy storage promotion program", if there is a 10 year warranty. (time worth warranty)

Does anybody know if Victron grants such a warranty? I know that Pylontec (the battery) does it. :)

The crucial point is that the whole storage system (incl. all components) have to grant such a 10 years warranty.

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.

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

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.
