Hi All

I have just fitted a victron system in my latest van conversion and it causing me a few headaches.

Any help is very much appreciated first let me give you the low down on what i have fitted.

Easyplus compact 12v 1600 inv charger

lithium 160 ah smart battery

V E bus BMS

12 65 battery protect

cyrix li charge

smart mttp

712 battery monitor

ccgx colour control

all components are at the latest firmware.

The issue is when running from the battery with the inverter and say im using a coffee machine rated at 1300 watts the dc cuts out a few seconds after the coffee machine is switched on then the ac cuts out. The dc switches back on a few seconds later.

I am presuming this is the battery protect kicking in and out the question is why is it doing this ?

I am new to installing a more advanced system and still learning .

Cheers in advance

Hello,

my iPhone-App forced me to update the firmware of the BT-Dongle. This failed with error B13 when updating to v2.23 The app tells me I have to sent the error log to the Victron support. But there is no answer since more than one week from the support-Mail-Account.

I bought it from amazon - so there is no support from the dealer!

What can I do?

Regards,

Toralf Nicht

My Impulse S12 charger is charging above 33 volts, setup is for 24 volt "wet" batteries.

Malfunction in the charger or is this normal?

Quattro 10k professionally installed March 2013. Off grid system, traction batteries 48v. Solar power 10 kw, 2 Sunnyboy TL 5000. Power failure at 0830 hrs August 2019. On investigation Quattro indicated an overload condition. (At this point in time basic load including 3 refrigerators could have been operating. All occupants of house in bed alerted by security system indicating a mains failure condition “No real load”. On advice from installer all AC output from Quattro turned off. All PV input systems shut down. Only power to Quattro was now DC at around 49 volts. Overload condition remained, indicated by overload LED. Attempted reset by turning Quattro to off position waited 5 minutes then turned Quattro on to Inverter mode. Quattro reset with no overload indicated. Waited a a few minutes then turned load back on to inverter. Same load as before (Virtually no load) system was working as expected. Ensured load was restricted for a while to ensure no overload possibility. All seemed to be working as designed. Returned to check system 15 minutes later and found the Quattro was indicating overload, making a horrible grinding sound and smoking. I isolated system by shutting down all AC load, shut down PV system and isolated battery bank.

This system has been well maintained, never overloaded and the room where it lives is cooled in summer to avoid overheating.

Very disappointing that the Quattro actually flamed out after 6 years. Contacted the closest Victron service agent. He didn’t sound surprised At what I had explained and mentioned “short circuit”.

This unit is not that far out of warranty and I am expecting no joy from the agent. I was surprised to read of how many instances where the overload situation has occurred with Quattro and Multi units. Seems this sustainable energy thing is very expensive especially if things catch on fire.

Any help would be appreciated in helping me understand how this unit could work well for 6 years then almost catch on fire. I would have thought protection would have been built in to avoid this situation.

Hello,

We are working on a project to charge/discharge a battery by using a PLC. We have seen that the Venus GX supports Modbus tcp/ip but it is not clear to us whether it is possible to control the controller via this protocol. Here we think of for example:

- Charging the battery

- Discharging the battery

- Charging speed of the battery

- Battery Discharge Rate

So we want to get the intelligence out of the controller and control it from the PLC. Is this possible?

Thanks in advance for your efforts!

I have a SBP-220 in my system. I have been performing a functional checkout of my system and have come across some unusual behavior in the SBP-220. When I tried to return from Off-Load to Active with the Load Output soft switch I received an E1 error, repeatedly.

I read an old post on this site about voltage drop and the length and diameter of the GND connection on the Battery Protector. I tried some of the recommendation, but I couldn’t relocate the SBP-220 so I was stuck with the wiring the way it is.

But what did make a difference really confuses me.

Once I switched the load off via soft switch, then switch my iPhone to Airplane Mode for 30 seconds (dropping out Bluetooth) then back to blue tooth mode, re-establishing communication with the SBP-200 from the Device List, I can then switch the Load Output to Active with no error. Go figure. Does anyone out there have any idea as to why this happens? I found 30 seconds blue tooth drop out was the minimum time period for a successful return to Active, repeatedly.

How does the SBP-200 sample for line conditions and how often? Is it a one-shot check and how long does it check to determine condition. Do the Preset User Defined values or Load Disconnect Mode settings have anything to do with the E1 error when manually trying load the SBP-200 via Load Output soft switch?

Below is the main power layout layer of my mounting shelf. The batteries are just below the shelf, in a lower compartment; needed 6' of 2 AWG wire to connect them. This is a slide out shelf, the reason for the 6' cables.

Hi,

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

Many Thanks

Hi,

Historically I have always spec'd systems with a battery protect to turn off the charge controller through the VE.bus bms. However recently seen schematics on Victrons page showing the charge controller connected directly to the CCGX with nothing to turn the charge controller off.

Has this been changed so the comms can control the charge controller based on what the BMS needs?

Matt

It appears that the only version of VictronConnect (VC) downloadable from the AppStore is 5.13 which is compatible only with OSX 10.12+. Is a version of VC available from somewhere that *is* compatible with OSX 10.11? My mac is so old I can't upgrade it any more (or at least nothing is offered why I ask for an update).

Can someone help me with error code 23 or 31? I can not find any information to this error codes and since this morning my Multiplus ist not working anymore.

My ccgx says status "unknown"

The graph selector on the dashboard disappears after the page has loaded and is not visible, and I can only see the system overview. What determines when this selector shows?

Thanks

Hallo! Ich habe Phönix Multi Plus im 3- Phasenbetrieb an Bord. Im Hafen gab es einen Elektrikfehler, vermutlich lagen zwischen N und L 400V an. Die Geräte funktionieren noch als Wechselrichter, schalten aber nicht mehr auf Ladung um. Man hörcht nur alle paar Sekunden ein Klicken. Was könnte kaputt sein?

Hello guys!

I have a three-phase ve bus system with two PV chargers.

I think I have some problems with in/out power calculation on the VRM portal.

If I take one-day data from VRM its looks like the PV to battery power more than the battery to consumption power. So how it's happening? If I take from battery-less then I use where the excess power is going?

For last couple of months my system ( 3 x 5 KVA Quattors in 3 phase with BYD 10 KWH) randomly resets ( all the quartos go offline and come back on)

#10 Alarm system time sync error, #1 device switched off commonly seen.

Initially, I Suspected network cabling so replaced with CAT 7 high-quality cables and cleaned the network sockets with contact cleaning fluid

Also, checked if all DC connections are tight ( they are )

There seems to be no pattern to these switch offs ( observed at 2 am in the night and also during afternoon or evenings ) -

The system works fine for a couple of weeks and in one day I could face one or more restarts with associated error logs

All firmwares are the latest except Quatro which are on V430 ( latest is 464 i believe)

Quetsions

1- Is there a detailed log somewhere indicating which unit is causing the shutdown

2. Should I upgrade quattro firmsware to rule out any other issues

3. Is this the issue of any external EMF affecting the network cabling ( they run parallel to the power cables - not in my opinion as CAT 7 are each pair individually shielded )

https://www.pcgamer.com/what-are-the-differences-between-cat5-cat6-and-cat7-ethernet-cables/

https://en.wikipedia.org/wiki/ISO/IEC_11801#CAT7

Class F channel and Category 7 cable are backward compatible with Class D/Category 5e and Class E/Category 6. Class F features even stricter specifications for crosstalk and system noise than Class E. To achieve this, shielding was added for individual wire pairs and the cable as a whole. Unshielded cables rely on the quality of the twists to protect from EMI. This involves a tight twist and carefully controlled design. Cables with individual shielding per pair such as category 7 rely mostly on the shield and therefore have pairs with longer twists.

Hello

I've noticed that setting the output "OFF voltage threshold" for the "user defined algorithm 1" to a lower voltage than the current battery voltage, will keep the load ON.

And it will keep on depleting the battery until you have a dead battery.

Secondary I have a problem when I hook up a 12V 3A POE switch. (using 15cm 6mm² leads to load)

Initially it works, but when the algorithm turns the output OFF and then back to ON, the output will oscillate fast ON-OFF-ON-OFF... forever.

It looks like a over-current protection kicks in to fast, or the MPPT 75/10 is not able to provide the 50A startup current that it is advertising in the datasheet.

For diagnostic purposes it would help to see the measured reason for this behavior in the VictronConnect App.

Hi there,

This is a problem observed consistently since the major mppt upgrade from 1.39 to 1.4x.

Mppt smartsolar 100/20 networked with BMV700 (dongle located almost next to the mppt, with a 1.5m extension cable). When significant current is being supplied by the mppt, Victron Connect mostly displays its battery voltage about 0.2 V lower than the BMV, despite it receiving the data from the BMV via the VE smart network . The actual voltage at battery terminals, measured with multimeter, is exactly that reported by the BMV (both on the device itself and via the Victron connect app). The measured voltage at the mppt output terminals is higher, of course, due to voltage drop across the connecting cables (about 1.5m of 13mm2 cable). If I remove the mppt from the network it correctly displays this higher voltage. Rejoining the network returns it to the anomalous readings above.

This is not just a reporting glitch of the app. The mppt apparently “believes” these anomalous readings. As a result, the mppt switches to absorb at a true battery voltage about 0.2 volts ABOVE the setpoint. If only looking at the mppt values using Victron Connect you would never realise this - the apparent battery voltage, as shown in the app, stays rock-steady at the set absorb voltage. Meanwhile, as the current reduces during the absorb stage, the true battery voltage gradually comes back down towards the correct set value by the time it switches to float. (This is almost the opposite of the behaviour before the update, when the mppt would switch to absorb about 0.2 V too low and gradually come up to the set voltage...I'm not sure which is worse.....)

The photo below shows a period of about 7 minutes during bulk charging. The mppt is producing about 18 amps, except for a brief drop at about 4 minutes as a wisp of cloud passed. Initially the caravan fridge is drawing about 3 amps, then cycles off for the next 5 minutes. The BMV showing the correct voltage values is on left, and the inaccurate mppt values are shown on right, displayed simultaneously on two mobile devices. The spike in reported voltage on mppt about a minute after the start of recording, corresponds to the fridge cycling off. That may have briefly disturbed the bluetooth connection, causing the mppt to suddenly “see" its real output terminal voltage (higher of course than the battery voltage) but then over the next few minutes it slowly returned to “seeing” a voltage well below the true battery voltage.

Possibly a glitch in the updated software? A bit annoying as could lead to overcharging of lithium battery.

Cheers, Leslie

The system is hybrid - 3 x Multiplus II 48/3000 in parallel with 30KW of Li Ion batt backup configured with ESS for self consumption with battery life. No feed in (not allowed)

ET112 appears as if it is switching on and off. Sometimes when viewing on the VRM the AC in is shown as 00 or -- then the system will switch back on again and will indicate 230V

And when I look at the history graph for AC In, it is constantly being switched on and off and the AC in is not constant - Is this normal ??

I’ve seen conflicting information for protecting my 3000W Multiplus inverter, in Victron’s system guides they show a Mega fuse. Many installers recommend a Class T fuse.

Does anyone from Victron have a recommendation for which fuse type is best to protect the Multiplus DC input?

Hi guys,

I would kindly ask the owners of 48/5000/70 Multis to confirm here if they ever seen charge currents over 50A in their systems.

I have installed two identical ESS systems in last year and none of them were able to charge with more than 50A even the solar power was plenty enough, all excess power is dumped into the grid. The REC-BMS LFP battery BMS didn't limit the charge current at such a low value.

Please see the pics below for exemplification.

Thanks,

Mihai

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.

Just wondering which use active BMS's ?

hi all

Currently, we are preparing an installation of a number of cabinets for deployment at remote mine sites, each containing a SmartSolar MPPT 75/15s. For remote access to the device, we are utilizing the VE.Direct port, to connect via a Serial to Ethernet bridge to the MS Windows VictronConnect application.

The issue that we have discovered is that during firmware update, the load output of the device switches off at about the 4% mark. The SmartSolar’s load output controls power to all of the down-stream network connectivity hardware, including the Serial-to-Ethernet converter, network switch and Ubuiti WiFi radio. This causes the update to be interrupted, with no possibility of it starting again without physical intervention at the Cabinet. The latter will not be possible as the mine site will eventually be inaccessible.

Any ideas are welcome. Alternative VE direct software, how to block VictronConnnect from checking latest firmware downloads, etc would be appreciated.

Hi Victron gurus

I have multiplus 12/3000/120 attached to a battery bank (12V SLA 550 Ah total new, at least 4 years old) and my Venus is dropping off the portal. The Venus is powered via the second 12V input/ouput which does not have a battery bank attached but is conveniently located to the Venus.

I suspect the battery isolator has been turned off while some work was done by an engineer and forgotten again. Last time this happened I was on the boat and recurring voltage alarms were what alerted me.

Does having the Multiplus (charger) on but the battery isolated do any harm? (If not then I will wait until I get back to the boat to check my suspicions rather than recalling the engineer).

Regards

Chris

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

Need to turn on/off inverter from inside motorhome

Hello,

I'm in the process of upgrading my equipment to Victron but I'm having a few issues with the solar charger voltage.

Currently I have

4x100AH flooded batteries (will be upgraded later)

120w solar panel (will be upgraded later)

Victron 3000w/12/50 inverter

Victron BMV-712 battery monitor

Victron 100/50 Smart solar

On random clear sunny days the solar voltage will drop to 12v but the following day it'll be back up to 21v. It isn't a weather issue nor panel as I've metered the solar voltage from the panel and it registers 21v but when plugged into the solar charger it reports 12v?

Here is photos showing the problem

https://photos.app.goo.gl/JEquFyeC4wyxuQdQ7

Any ideas?

Hello,

hello everybody,

i m using an ESS system, three phase, 2X BYD batteries 10 kW; PV area 9,6 kW, 3 X Multiplus 5 kVA and Fronius Symo 10 kW.

satisfied with more than one year from the installation of system; monitoring for long time with separate devices from VICTRON - i m using also Color GX from Victron as part of system.

for attached pictures, in a cloudy day, at the moment with sun on sky we can see that my house is using energy from grid also and in the same time is injected energy into the grid, even batteries are near empty.

as the ESS system is configured to feed battery first is appear that is not so optimised to do this job , and need some attention .

Can someone from Victron specialist explain what can be the reason of those graphs ?

clear in the another hand, my system is configured with minim injection on grid, approximately 30 W, because in configuration with 0W injection is became more unstable and energy injected on grid is bigger.

thank you,

laurentiu

Hi all,

can some explain the different between this two devices please ?

Multiplus 12/1600/70 vs Multiplus 12/1600/70 compact

Thanks Hoagie

I'm trying to read the firmware version from a mppt 75/15 via Vi.direct (hex). I' was trying the 3 command "App version" but I don't know what the data bites are. With the get command 7 it's clear using the register i.e 0xEDEC for battery temp, but how is this done with comamnd 3?

Get: :7D5ED00[checksum]\n is working for charger voltage

how is the syntax for command 3? :300 [checksum]\n is not working

thanks in advance

Juergen
