Pylontech L-V Hub problems with Quattro 48/15000

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.

Pylontech High Voltage Alarm

Hi I'm getting hIgh Voltage warnings on the CCGX. I understand the cells need to internally balance as it's a new system. They are, slowly, day by day.


My issue is that I have set the DVCC to 53.2V to mitigate the alarms and to allow the cells to balance but it's not stoping the alarm!.


Any ideas?


The alarms currently trigger just above 52V.

Configuring Multiplus with Pylontech Batteries (Possible with just CerboGX and Touch 50)?

I have a solar kit I bought recently with a Multiplus 48/5000/70 and a SmartSolar 250/100. The system has a CerboGX and Touch 50. The battery bank is 4 Pylontech US3000.

I was reading the Victron-Pylontech compatibility article, and just watched a webinar on the topic, but I'm still unclear.

To make sure all my Victron components are configured properly according to what the batteries need, can I just use the VictronConnect app via my smartphone? Does this operate via some sort of bluetooth connection internal to the CerboGX?

Or do I need to buy the Smart Dongle or MK3 USB separately?

Doesn't the CerboGX and Touch50 replace the need for the VictronConnect app or at least replace the need for the SmartDongle/MK3-USB?

wie arbeitet dvcc genau ? funktioniert das so, wie ich es brauche ?

hallo,

ich plane eine erweiterung meines systems mit einem weiteren akku und 3 multiplus II, sowie einem gerbo gx mit aktiviertem dvcc.

allerdings weiss ich noch nicht, ob das alles so funktioniert, wie ich es moechte. deshalb habe ich dazu noch ein paar fragen:

- wird wirklich der strom der mppt-ladereger direkt gesteuert oder nur die ladespannung so eingestellt, dass der gewuenschte ladestrom erreicht wird. in meiner ersten anlage mache ich das naemlich genau so. das hat naemlich den vorteil, dass es nicht noetig ist, immer gleich nachzuregeln, sobald die last sich aendert.

- ich will auch mehrere spannungswandler und andere verbraucher direkt auf den akku anschliessen. damit der strom erfasst werden kann, werde ich diese verbraucher an den lastausgang eines mppt 100/20 haengen. funktioniert das dann auch mit der ladestromeinstellung noch, wenn die (an diesen laderegler angeschlossenen panels) weniger leistung bringen als die last benoetigt ? wenn die last direkt am akku haengt, fuehrt das ja zu einer verringerung des ladestroms um den strom der last.

- ausser den multiplus will ich auch noch einen wechselrichter mit ve.direkt-anschluss einbinden. kann ueber dvcc dann auch der strom dieses wechselrichters kompensiert werden ? ich konnte leider keinen entsprechenden hinweis finden. mit einem weiteren ve-bus-system und einem mk3-usb soll es ja funktionieren.


da ich auch noch nicht weiss, welche informationen ich ueber das gerbo gx vom akku bekomme, werde ich wohl noch ein bmv 700 anschliessen, das dann die daten fuer meine datenerfassung liefert. zumindest so lange, bis ich die daten aus dem gerbo gx automatisch auslesen kann.

Multiplus II entlädt die Batterien nur bis 97%. Ohne Solareinspeisung MPPT 150/35 wird überhaupt nicht entladen

Hallo an alle.
Ich habe seit Oktober einen Multiplus-II, Cerbo GX, MPPT150/35 und 3 Pylontech US2000. Auf dem Dach sind je 6 Solarmodule an der Ost- und Westseite montiert.

Alles zusammen funktioniert soweit problemlos. Gedacht ist es als UPS für kritische Lasten (Server, Telefoanlage, Heizung, Beleuchtung, Gefriertruhe). 50% der Kapazität der Batterien reicht für den unabhängigen Netzbetrieb über die Nacht aus, bis wieder Solarenergie zur Verfügung steht.

Der SOC Mindestwert ist ist im ESS auf 50% gesetzt. Das hat aber keinen Effekt! Steht Solarenergie zur Verfügung und ist die Ladung bei 100%, wird kurzfristig die Last aus der Batterie und Solarenergie versorgt, bis der Ladezustand bei ca. 97% ankommt. (49,7V an der Batterie). Danach wird die Batterie wieder geladen. Kommt mehr Solarenergie an , als benötigt, wird in das Hausnetz eingespeist. (Gridmeter soll auf 0W gehalten werden.)Bleibt die Solarenergie aus, wird die Batterie nicht mehr entladen und bleibt bei anfangs 100%.

Ich würde gerne die Batterie über Nacht bis zu der eingestellten Grenze von 50% entladen und erst dann Energie aus dem Netz nutzen.

Das gelingt mir nur, wenn biem Multiplus-II "Netz ignorieren" aktiv ist.(Trennung vom Netz bis eingestellte Grenze erreicht ist) In dieser Einstellung funktioniert das Einspeisen ins Hausnetz aber nicht mehr. Bei guter Sonneneinstrahlung wird der MPTT gedrosselt und ein Teil der Energie geht "verloren", den ich im Hausnetz hätte nutzen können.

Die Firmware habe ich bei allen Komponenten im Oktober aktualisiert.

Ich habe schon zahlreiche Konfigurationen durchprobiert, kann aber den gewünschten Ablauf nicht erreichen. Stehe ich hier selber auf "meiner Leitung"?
Irgenwie finde ich den Einstellknopf nicht!

Für Hilfestellung bin ich dankbar.

Nun kommt es immer wieder vor das Nachts oder am Morgen Strom aus dem Netzt entkommen wird obwohl der Akku noch mehr als 10% hat(10% ist mein Soc) . Wie auf dem Bild zu sehen ist wird Strom aus dem netzt entnommen obwohl der Akku 30% hat und zudem wird sogar noch aufgeladen.

Teilweise habe ich beim Laden den Eindruck das Victron nicht richtig misst oder Werte fürs laden als Verbrauch annimmt ???

Updated Pylontech wiring

Victron has updated its Pylontech Wiring. See the picture below.

[image]

In the version before, the GND cable was connected to the negative pole of the DC Distributor.


Now they have excluded the GND cable at the negative pole of the DC distributor. So the system is not grounded at the negative pole anymore.

Why did they change it?

Is it true, that the negative pole of the Battery is connected to Ground over the case Ground, as this fellow says:

https://community.victronenergy.com/questions/48804/pylontech-battery-earthing.html

I have read in the MPPT manual:

WARNING: WHEN A GROUND FAULT IS INDICATED, BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE UNGROUNDED AND HAZARDOUS.

So the MPPT should be grounded on the negative pole am I right?

Comment remédier au problème?

Est ce qu'un fils can-bus entre la batterie et le CCGX résoudrait le problème?
A mon avis le problème pourrai venir de la batterie qui doit se protégé d'une grosse charge (ici un pic de 3000w lorsque j'allume la machine)


Ou est ce qu'il faut modifier quelque chose dans le multiplus, qui dois être en mode ESS d'origine?

Venus OS v2.60 & Pylontech batteries generating high voltage errors

Hi.

After updating my ColorGX to 2.60, the Pylontech batteries (installed and configured since more than 1 month according to Victron document), the charging voltage is getting now up to 52.5V and generating high voltage errors. Before this, the maximum voltage was 52 - 52.1V. No other changes were done on the system after batteries were installed, and yes it took 3-4 days for them to balance each other.

So, anyone else experiencing this? Is this a known error?

State Of Health Degradation Rate - Pylontech US3000

Hello

These Pylontech batteries have been around for a while. The design life on the US3000 is advertised at 10+ years at 25℃.

I understand that SOH is directly affected by usage, charge state and operating temperature. No two installations will be the same.

I am interested in your experience with these batteries specifically around State Of Health (SOH) rate of degradation. What is the average SOH degradation rate (% per year) across your installations? Is this more or less linear?

Suitable Circuit breaker between multiplus-ii and battery

Hello everyone,

I want to put a double pole MCB between a MultiPlus-II 48/3000/35-32 and 3 48V Pylontech batteries.

Pylontech recommends 25A for each Package and it supports up to 100A of discharge for each Package.


Victron states in manual:


-You must have the minimum number of battery modules to supply the inverters startup inrush surge currents that charge the capacitors when the inverter is first connected, this occurs prior to any loads being connected. For this Inverter, 2 Batteries are minimum.

-Victron recommends a 125A MCB between battery and Inverter, since its Peak power is 5500Watt (3000 AC Load + 1500 feeding in shore power)

We dont want to feed in the shore power, so only ac loads left. 3000 W / 48 V = 62,5 A. So an 80A MCB should be fine, but maybe the Inverter wants to pull more current? Maybe the stated 125A due to the startup inrush current?


I found 3 MCBs (80A, 100A, 125A) from the same series from ABB

https://new.abb.com/products/2CCF019606R0001/s802pv-sp80-high-performance-mcb


I really would like to use an 80Amp MCB, so that the Inverter does not pull much more than the calculated 62,5 Amps.


My Questions:

Do you think the 80Amp MCB will "handle" the startup inrush current?

Does the MCB could have a minimum operating Voltage(Datasheet not found)? Is 48V fine?

Is the rated Ultimate Short-Circuit Breaking Capacity (Icu):(800 V DC) 5 kA enough for a 7,2kWh battery system?

If you have remommendations for other MCBs, please share.

Battery Monitor[512], Alarm - High Voltage Alarms - Victron Multiplus and Pylontech Battery

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.

Off-Grid - Multiplus II GX and Pylontech/Liontron

I want to build an offgrid system that mainly will be used during the summer.

Briefly outlined:

Energy generation, storage:

  • Phoenix Combi 12V / 1600W (we already have)
  • 4x PV panel 300W
  • MPPT 250/100
  • Car battery 12V 45Ah

Consumers:

  • Waterpump 1 phase 800W - 230V, 1h/d during summer
  • Intrusion detection (SMS module ca 5W, 24h/7d)


The system will be placed in a gardenshed.


The following questions come to mind:

  1. On a sunny day, will the power flow directly from the MPPT to the inverter?
  2. Plans to a future upgrade to a 48V system. I made calculations for the battery pack and the result was a 4x 12V-110Ah Gel battery combination. This was based on the rule which limits the maximum charge and discharge currents in regards to their expected lifetime. For this 48V system i need 3 battery balancers, which have their costs. My friend google found the Pylontech or Liontron LiFePo rack system. These systems have an integrated BMS. Can I use the Multiplus II GX or EasySolar II GX for the communication with the BMS of the rack battery? Or do I need an seperate GX device. And what power consumption is to be expected from this GX device.
  3. Do I need in regard with the future, buy the MPPT with ve.can functionality for communication with battery rack?
  4. Shouldn't Victron upgrade their MPPT's to higher voltages? I understand that more PV-panels on a string is a better choice. 250V seams limited to me for future design, if compared to AC-grid inverters.

Camper Van Schematic - please critique

Hello everyone :D,

please check my schematich below. Feel free to criticize the schematich.

Here are some side notes:

This PV schematich is intended to be installed in Germany on a camper van. 80% of the time it is off grid and 20% on grid. Since I have not a GND connection on the DC side, I want to protect the postive side as well as the negative side, as it also proclaims the German Law. 3 x Pylontech US2000 batteries are used. The PE is connected in our case to a grounding strap for cars, which touches the surface of the asphalt.


Here are some short things, where I am unsure:

Should I connect the PEoff the Grid to the PE from the van. The MCCB at the Multiplus is really obsolete in my opinion, beacause all supply lines (which go to the multiplus) are protected. Unsure about the ESS, because it is actually only for on grid applications, maybe a HUB2v2 is a better option, but no one is using it.

Quatrro inverter shutdown on Pylontech low battery

Hello,


Recently got a system consisting of:

1x Quattro 48/3000/35

2x Pylontech US3000c

2x BlueSolar Charger MPPT 150/35

1x CerboGX


As part of my testing I ran a load until shutdown. What happened is that the whole system turned off at the low voltage point. The Pylontech shows the RED alarm LED. The Victron setup does not seem to see any DC power at all at that time (touch display off etc).

It would be nicer if there is a shutdown mode where the inverter is disabled (but still powered, just not generating AC). That way the display still shows what is happening. At some point the batteries are going to turn off completely and then whole system will be down.

I've had bad experience (with another vendor) where it becomes a real struggle to get the inverter/charger to wake up when there is (generator) AC, but not DC yet.

Is that not an issue with the Victron, as soon as I apply AC the system comes back to live?

Also, when the system was in shutdown, non of the console commands on the Pylontech seemed to indicate a powered down state :) I must be looking at the wrong command since the inverter saw low voltage over CANbus. What is the correct command to see historic shutdown reasons?

Correct DVCC setting for Quatto + Pylontech US3000c + Bluesolar MPPT

Hi all,


Recently got a system consisting of:

1x Quattro 48/3000/35

2x Pylontech US3000c

2x BlueSolar Charger MPPT 150/35

1x CerboGX


All firmware updates available via the VRM portal have been applied. I don't have a USB adapter, so I guess the inverter is on the firmware it came with.

The Pylontech - Victron setup manual says that the DVCC settings will be automatically populated. This was not the case for me.


What settings should I use for my setup?

DVCC -> On

SVS Shared Voltage Sense -> ?

STS Shared Temperature Sense -> ?

SCS Shared Current Sense ->

SCS Status shows "Disabled, external control"


When I enable limit Charge Current, it defaults to 50A. But I can change it.


It does look like the system sees the batteries correctly. Looking at the max charge current on the battery view, it matches the two batteries I have in my system.


Thank you!
