Pylontech Internal Error Alarm

A little over one month ago I installed Pylontech US2000C batteries in my system. All was well for 3 weeks and then 2 weeks ago the first Internal Error appeared.

Having scoured the internet and following the advice from Victrons own documentation I lowered the DVCC Maximum voltage to 51.2 (15 x the voltage of the lowest cell voltage seen in the remote console)

I could see in the VRM Portal that there were multiple spikes in the Min/Max Cell Voltage's when there was no corresponding spikes in the AC Load (perhaps someone from Victron or Pylontech whould care to eloborate on that)

Over time the number of spikes diminished, until yesterday when they were back and today, once again, an Internal Error Alarm happened.

Looking at the data from the VRM Portal I can see that the spikes only happen when the cell voltages reaches 3.27 and the alarm happens when the Max cell voltage hits 3.89, a difference of 0.62 volts. This behaviour has been consistant for all of the alarms, to date there have been 12 of them in a 2 week period.

I am now somewhat at a loss as to what can be done to mitigate this problem.

Cell balancing in a Pylontech battery

Hello Victron friends
I am installing a third Pylontech US3000 battery to boost the storage capacity of my off-grid system, and am once again getting high voltage alarms. The battery arrived with SOC = 39% and I am charging it by itself using solar panels via the EasySolar II. The high voltage alarms started at 73% SOC & 50.6V and so I used the option in Remote Console DVCC settings to limit the charge voltage to the max possible without triggering alarms, ie 50.5V. I have included a screenshot from BatteryView.exe which shows what I presume is the problem: Cell 3 is at 3.51V, much higher than the others which are 3.3 - 3.4 V. The situation has changed little from yesterday to today, and I have some questions to ask of anyone who might know more about the internal cell balancing processes than I do.

- Is an external current input necessary to charge the low voltage cells, or do the cells redistribute charge among themselves? If they can redistribute internally, does it also happen when the battery is disconnected but switched on?

- I understand that cell balancing uses quite small currents. Am I going to have to wait for all of the other cells to catch up with cell 3? That would be a lot of amp hours and presumably will take a long time.

- Would the cell balancing be adversely affected if I connected the three batteries together? Running off three batteries rather than one would be more convenient as it would give me enough capacity to last through the nights and I wouldn't have to juggle the batteries.

Thanks!

INVERTER 'RED" Alarm Fault

We have a 24 V / 2000 VA / 50 Hz MultiPlus Compact inverter which has worked perfectly for 2 years now. Suddenly 2 days ago it has not gone into inverter mode when we have a mains failure and the "red" alarm light just stays on permanently. When the mains are on the charging light is on and flashes. I have checked the DC output fuse and it is perfect still. Ive checked the battery no-load voltage which is 26V DC. However i did notice when i turned off the mains this battery voltage dipped to 17V Dc briefly before the "red" alarm light came on again and there was no output from the inverter again. I checked and there is no sign and no smell of anything burning. Can you advise what the fault might be. I should advise that i suspected the batteries - but until 2 days ago the inverter was able to run our full house lighting load , plus TV and WiFi easily for 2 hours so im not sure its suddenly the batteries. Any advise will be appreciated.

Alarms - Automatic Reset

EasySolar 24/1600/40

I keep getting a transient battery temp alarm. This comes on and I've traced it to a heater blowing hot air over the sensor.

But the only way I can find to reset it is manual. What I want to do is firstly delay the alarm activation (something like trigger alarm if condition exists for longer than x minutes). And automatically clear when condition clears. Also with a time setting.

Searched all over, found nothing. Nothing in the manual, nothing in the configuration software. But I'm very good at not finding things. Has anyone come across this?

How to programme an alarm for powerassist

I am installing a multiplus (24/3000/70) on a large houseboat permanently connected to shore power. The boat has frankly too many systems for the 16a shore breaker, and the idea is that the PowerAssist feature will prevent startup spikes from AirCon etc. from tripping the breaker. My concern, however, is that the occupants will abuse this feature and destroy their own battery bank. Ideally, I want to set an alarm to let them know when PowerAssist has been on for more than 1 minute, or failing that, set a limit after which PowerAssist will stop and simply trip the breaker (cheapest way they’ll learn!). It seems like this should be a feature as there are three programmable alarm outputs, but I can’t find anywhere how to achieve this. Any help appreciated!

Pylontech tension élevée

Bonjour.
Mon système comprend deux batteries Pylontech US3000C, l'onduleur RS Smart Solar 48/6000 avec son MPPT, le Cerbo GX et le GX Touch.

Tous les jours, lorsque les batteries atteignent 100% de charge, j'ai une alerte de tension élevée indiquant une valeur allant environ de 54 à 54,2 V. Hors, effectivement, la tension maximale des batteries devrait se limiter à 53,5 V.
Je suis donc allé dans la section DVCC (qui est activé), pour activer "Limit managed battery charge voltage" et régler "Maximum charge voltage" à 52,5 V. La limite de tension de charge (CVL) de la batterie est de 53,2 V.
Cependant, ce réglage semble n’avoir aucun effet sur l'installation et j'ai toujours des alarmes au-delà de 54 V. J'ai même essayé de mettre "Maximum charge voltage" à 51 V.

Tous les logiciels sont à jour et j’essaye de ne plus avoir cette alarme depuis cinq jours (jour de l’installation du système). Cette tension d’environ 54 V est brève et le système passe en "float" très vite. Si je branche alors quelque chose qui consomme comme un aspirateur, l’énergie solaire rentre à nouveau vite dans les batteries et une nouvelle alarme se déclenche.

Que puis-je faire ?

1560Ah 48v lithium 3-phase quattro 48/15000/200 x3 battery config 82kWh

First, I've read countless articles trying to self resolve my issues. The vast majority seem to be people using very small systems...and my issues seem to be different. Or other people have bluetooth connectivity to their MPTT and I don't...so not sure if I need to get a USB cable and connect, or I can do things online.


Two issues I want to solve.

1.) Low battery alarms are useless. I want them off, but I can't seem to stop them. My battery is at about 44% (46v), and the alarms are configured for 25% and I continually am getting non stop notifications. VictronConnect on my BMV700 I don't think is related to this, and I have alarms disabled on the remote console...so what is sending these alarm emails so I can stop it? Or at least get it to somehow respect what 25% actually is instead of it having some other calculation its doing.


2.) I cannot get the battery settings correct in VictronConnect on my BMV700. I have to keep monitoring the percentage as it keeps getting off a little. Battery capacity is set at 1560Ah which I know to be correct. 13s13p packs with EIG 20aH cells = 260Ah...with 6 of these in parallel = 1560Ah. I've read for Peukert that its effectively close to 1.00 for Lithium...and especially considering how large my capacity is, my batteries never get any stress at all. So I am actually using "1.00" currently. I've been testing that at 1.00 to 1.09 with equally confusing results of not calculating the correct percentage based on voltage. I'm wondering if I need to toy with the capacity value to get one that helps make the SOC follow correctly...


Help or guidance on how to properly set the config so it follows reality on the batteries? Attaching screenshot of the config currently along with battery specs.

Victron-Pylontech high voltage alarms

I’m having what seems to have been a common Victron-Pylontech problem, namely high voltage alarms. I am off-grid, and have an EasySolar II with two US3000 Pylontech batteries, which I installed a few months ago. Because initially I only had a few panels (needed to build a verandah so the rest could go on its roof) the SOC rarely got much above 80%, and I kept the show on the road with a generator. Last week I switched on the full complement of panels and since then, whenever batteries reach about 51.5V or 90% SOC, I receive repeated high voltage alarms.

I looked at the Victron-Pylontech set up document:

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

A suggestion in Section 9 (FAQ and known issues) was to allow cell charge levels to balance out by temporarily limit the maximum charge voltage, and it showed the screen:

[image]

However when I use Remote Console to look at the DVCC menu I see no option to do that:

[image]

Am I perhaps missing something here, or has that override capability recently been removed?

Any suggestions would be welcome, especially if they don’t involve doing things that might affect the battery warranty, like disabling DVCC.

MultiPlus 12/3000/120-50 120 Temperature Sense error and Battery Temperature alarm

I have an ongoing problem with what seems to be erroneous High Temperature alarms on the Multiplus 12/3000/120-50.

The unit details:


Product
MultiPlus 12/3000/120-50 120V

Firmware version 475

Last connection 5 minutes ago

Product id 2702

VE.Bus connection VE.Bus

Hardware configuration Single unit

VRM instance 0


Things I've done to troubleshoot:

-- checked all terminal connections... everything is tight.

-- manually measured surface temperature of multiplus, which ranges between 20C and 30C.

-- upgraded firmware to latest version

-- temp alarm doesn't seem to have a pattern for which it gets tripped. When the alarm goes off, there doesn't seem to be excessive load on the system.

-- I observed that the fan on the unit does not come on and I thought it was a faulty fan. I added a large load to the system by turning on the AC unit when inverting and the fan promptly came on. So, I'm thinking the fan is working as it should.

-- the unit is installed in a bench seating area, which is enclosed. I thought ventilation was a problem, so I added 4 cooling fans and external ventilation, still received alarms.

Any ideas on what else to check?

I know I can connect a GPS to the GSM GX cellular modem but can I set an alarm without using a GPS device (perhaps using Lat / Long or Speed alarm rules?). If so how will the unit 'know' it has moved - does it 'know' its location if I have set it manually on the VRM portal or is that simply a 'point' that I have designated it to be on a map and it does not really know its own location.

MultiPlus-II 24/3000/70-32 temp alarm at 2300w load

Hi,


I am in the process of load testing the Victron system in my camper, and I have a question regarding the inverters performance.

I ran a load test with a heater pulling 2.300w (reported by the inverter), and after about 30 minutes the inverter shut down with a high temperature alarm. The ambient temperature was around 15 degrees and the inverter is (currently) mounted free without anything enclosing it. The inverter is running the latest firmware.

What could the issue be here? I would expect the inverter to be able to pull the 2.300w load until the batteries was empty.


Yours sincerely,

VE bus low voltage alarm multiplus while voltage seems ok?

Hello


Yesterday i changed my low-voltage settings in VE configure. I set the low voltage pre-alarm and restart at 11.8 volts. I am running 2 x 230 ah agm super cycles.

Today i suddenly got overloaded with, for me, unnecessary VE bus low volotage L1 alarms.


From all the alarms i can only understand one of the last alarms; voltage dropped to 11,87 so that one seams logic for me. The rest of the alarms is when voltage is around 12,37 or higher. Why are these alarms?


Is the setting in VE configure the one that is connected to these alarms, or is the VE bus low voltage alarm connected to another setting? I disabled the alarm rulesin VRM so that is not the issue.


Battery SOC was around 97 percent and i am running within maximum discharge current of 92 amps

VRM grid lost alarm will not clear

I labelled my Quattro AC input 1 as ‘shore power’, then set up an alarm rule on my CCGX where all input labels (not available, grid, generator, shore power) were enabled.

When I disconnected my shore power, the CCGX and VRM gave me ‘grid lost’ alarms. I acknowledged the alarm on the CCGX and reconnected shore power but it took a reset to clear the CCGX, and I can’t clear it on the VRM.

I’ve tried deleting the rule and setting up a new one, re-labelling my input as ‘grid’ to see if that’ll clear it - no luck.

Any advice appreciated - would like to clear from the VRM.

Pylontech warning low temp after internal faliure

Hello,

I got this now three times during the past four weeks. Suddenly there is a Notification / alarm when the Pylontech batteries are almost full.

It starts with a "simple" Internal failure at 12:03 and after some time it is followed by a low temperature warning, today with 23.7°C ;-) followed by a second internal failure alarm at the same time.

Any ideas? Can I try to find it out what happened and what caused it.

In VRM it shows some more information

Battery Monitor [512] Automatic monitoring Internal error alarm: Alarm 2020-06-18 12:18:19 3m, 46s




I think it might be a sort of communication problem. The pylontech batteries doesn't show any Alarm LED or any other sign of problem. I am still running a release candidate firmware 2.60~23 and there is a some how newer version with 2.60~25 available, but in understanding never change a winning team, if not neccessary, I hope I get some advises here.

I looked at the monitoring during this time

[image]



Here some more detailed screenshot from VRM for battery information for 12:03

and for 12:18 when the second alarm notification occurred.

But I couldn't see anything really spectacular. Perhaps it might be interesting that the Pylons BMS changed exactly at the first point of time the CCL down from 80A to 20A.

Any ideas, what I can do to follow the alarms and to find out what did it cause?

How can I delete or inactive it, so that if I have a new alarm, I will immediately see it having it display in the red bar instead of the permanent old one?

If nothing possible on my side, can someone at Victron delete it on the VRM back-end.
