System shutting down when batteries reach around 26 degrees..

We have a fairly new set up on our narrowboat with 2 X 150 AH Lifepo4s. Charging from engine or solar. We are using a relatively low amount of power, and the batteries have barely been below 80% charge. A couple of weeks ago we noticed the system seemed to shut down for no obvious reason. At the time we thought it coincided with new appliances being added, eg a 12v fan or using a new tool/phone charger (via the multiplies). Now it is more frequent and we think is linked to charging and battery temperature. It happens when we enable the solar to charge or when we run the engine to cruise or heat water in the calorifier. And it always happens when the batteries reach around 26 degrees or go above this. The red LED (Cell <4V or temperature) on our VE BUS BMS comes on at the same time. Whatever it is, this doesn't seem like it should be a problematic temperature, but as soon as the system shuts itself down we're then powerless to do anything; either to investigate the issue, or to use basic on board facilities.

VRM Reporting Error

I'm not sure if this is the right place to put this, but I can't change the fuel price to what it actually is.

It is limited to a maximum value of 5, which when working in Euros (€), Dollars ($) and Pounds (£) I am sure it is perfect, but when working in Rands (R) it doesn't work. Our fuel price fluctuates between R13/l - R16/l, I guess it can always go even higher than that. Is it possible that the slider can be extended?

On a totally separate note, is it not possible to also create a scenario where it generates your actual electricity bill, not a comparison report?

Quattro 48/5000/70-100/100 120V Bulk and absorption LEDs flash synchronously and Vdc shown at VE Configure monitor is different to the battery actual voltage

Problem description:

After installation the equipment performed fine, completing the battery charging cycle. After the first grid AC power outage it switches to the inverter function and supplied energy from the batteries to the loads for about four (hours). When the grid AC power returns it switched to the charger function but showing continuous LED light in the mains on indicator and the bulk and absorption LEDs flash synchronously (simultaneously). Low battery is shown shortly on startup.

[image]

After switching off and on the equipment the error indication remains and the batteries are not charged. After recharging the batteries using an external charger and reconnecting them to the Quattro it doesn’t start using the manual switch.

Using VE Configure III the Quattro restarted and it shows that all default setting are OK. However the monitor shows DC voltage Vdc = 24.9V which is completely different to the 48 V measured using an external voltage meter. The SoC bar I the monitor also shows the battery charged . Bulk and absorption LEDs remains flashing synchronously.

[image]

Can anyone provide any orientation about this failure and its resolution procedure?

Phoenix Multi Compact 12/800/35-16 Overload Warning and Low Battery Alarm

Dear all, we have recently bought a Multi compact 12/800VA together with a SB SUNLIGHT AccuForce 12V - 150Ah Solar VRLA Battery in order to replace an ONLINE UPS in a on-Grid Photovoltaic 500kWp installation. The system works in 12V mode. The inverter charger is connected to the AC grid and the only load is the Protection Relay (SEPAM) from Schneider Electric installed on the Medium Voltage Switchgears Board. The charging mode is 99% in "Storage" mode cause the load is very little. The problem we are facing is that after two or three days of operating the Inverter goes to fault mode and the alarms we got is overload and today together with a Low Battery Alarm and the PV station goes out of the Grid. The only thing we do when the fault comes is to go and turn off and on the inverter/charger and the problem is (temporary) solved. Today the fault happened, we got a "grid lost" e-mail message, when we reached the inverter the fault was gone (only the green light when on), as it seems the inverter was inverting. We turned off and on the inverter and the inverter "saw" again the AC grid.

Since we bought the inverter we did not do any optimizations or changed any settings for example for the current output (everything is as it came from the distributor). The system also has a Color Control GX and we can monitor the system from the VRM Portal. Please see attached pictures, videos. Any ideas for the fault or settings needed are much appreciated! No clue why thr fault takes place, on the other hand the overload maybe comes because the SEPAM maybe draws a lot of current in order to power the motorized central medium voltage circuit breaker.20200316 Status Monitoring2.jpgfaults.jpginput current limit.jpgMV SEPAM.jpgBattery.jpgGrid connection restore.mp4

bluesolar panel voltage during night > 0 ???

I am not sure if this is normal, so my question is to all of you that use mppt bluesolar charger. While the battery is connected to the charger, I can also measure similar voltage on the solar input terminals. This is regardless if solar panels are connected or not. So if voltage of the battery is 50V, on the PV terminals I can measure 50+ something volts also. Same is displayed in victron connect screen. Does your charger displays solar voltage > 0 during the night also? Shouldn't it be 0V during the night? Perhaps something got fried in mine :-/

Lots of problems with ESS multiplus 2 (error 24)

I Installed a multiplus 2 with 10kWh of BYD batteries in an ESS system first half of the year, it worked well for a month or two then started bringing up error 24, I followed the instructions for what to do for error 24 and sent them off to my victron distributor, victron decided to send me a new unit, I intsalled the unit and instantly had the same problems, after lots of return visits and firmware updates in the hope the issue had been found and resolved which is costing me lots of time and money ive realised that the unit will go straight into error 24 with the current sensor plugged in, If i remove the sensor and restart the unit it starts fine then plug it in it begins to act as an ESS system should with no error code, the problem being that i simulated a power cut by turning the AC isolator off and then back on, and as the sensor is in it goes into error 24, i have updated the firmware twice and replaced the unit. Its a real shame as its also costing the customers confidence in the system i have installed for them, and I cant keep going back to resolve this I have seen on the VRM it is in error 24 again today and i went to them on friday. It has the latest 2629 467 firmware intalled and the UK G98/G99 grid code. Please can you sort a resolution for this ASAP.

MultiPlus-II 48/5000/70 continuous overload shutdown

MultiPlus-II 48/5000/70 is shutting down continuously with an overload error after some issues on the grid network.

Batteries are full and the external grid is off (as the mains circuit breaker failed). BlueSolar Charger MPPT 150/70 is connected and providing power (as the sun is up...)

Now the MultiPlus keeps trying to start up, but fails within a couple of seconds with an overload error. However, the circuit breaker towards the load is off as well, so there literally cannot be any load on the inverter at all.

Is this a bricked MultiPlus or is something else going on?

Tried a lot of stuff, including restarting the system through the Color Control GX as well as with the on/off button itself.

Anything else to try?

The system is installed in the south of France, and I'm asking for someone else, so troubleshooting is going to be a pain.

Another overload has occurred with no obvious reason

Quattro 10k with ESS Grid connected / solar / CCGX.

Previous overload switched off system and due to lock out could not be re started without intervention by un plugging CCGX. Freezer contents lost as we were away.

Just now a year later same overload situation. No warnings - system tripped off.

Overload LED lit. Prior to event Voltage was 48v and load was around 500w. System was discharging as it was after sunset.

At 18.00 voltage dipped from 49.90v to 46.40v and current dipped from -11.40amps to -44.20 amps which was the event. Reset the quattro = 50.20 v and 0.10amps then it reverts to 48v and -7.60 amps which is normal.

No errors or warnings recorded.

The only loads to stress system would be well pump/ freezers no other loads with high inrush.

These loads are running all day without a problem.

So what causes a massive dip in current????

Multiplus II 3000 GX External Current Sensor Error 24

Good Evening Victron Community,

I have installed a Multiplus II GX in a topology with all Non-Critical Loads upstream of the AC Input. Critical Loads on AC Output 1 as usual.

When installing the External current sensor on the Main Circuit and returning from an Outage the Inverter gave an Error 24 related to the backfeed relay.

Although the error makes sense to me regarding it seeing Current (from the external sensor) while it was expecting no current (Ac-In relay open) I would think that selecting the External Current Sensor Connected tick box in VEConfigure would tell it to ignore this discrepancy?

I have since removed the Current Sensor (and unticked the tick box) and have tested the exact same outage successfully without Error24.

Although this post mostly serves as a possible bug flag, I would like to end it with a question.

Would it be possible for me to install a three phase Grid Meter upstream of the AC Input and non critical loads (Carlo Gavazzi 65A) instead of the Current Sensor and still avoid this Error 24 Situation?

If yes, would I be able to add an unpowered USB hub onto the USB port to have both an external Wifi adapter and USB to RS485 adapter on the GX portion in order to connect the Grid Meter?

Kind Regards

What does blue tooth have to do with clearing an E1 error?

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.

PV rapidly fluctuates between 1 and 130w in Bulk - Battery voltage spikes to 14.65 then drops.

Hi, I'm getting some worrying behavior from my set up today. Not something I've seen before. It's a mixed day with clouds and then full sun.

When overcast everything seems normal.

When the sun comes out the PV wattage jumps right up and the battery voltage spikes to about 14.65 volts. Then the wattage then immediately cuts right back to 1 and the battery voltage reduces to 13.3ish. The watts and voltage then jump up and rapidly max out again, and the cycle repeats.

It is doing this in both absorption and bulk mode. The absorption voltage is set to 14.4v and float is set to 13.67v.

My equipment is:

  • 100/20 MTTP
  • MTTP Control
  • 200w 24v Victron Panel
  • 100Ah 12v pure lead/carbon battery
  • BMV 700

Having done this all morning - rapidly fluctuate between 1w to 130w PV and 13.3v to 14.65v battery in both absorption and bulk modes - it's now stable in float at 35w and 13.64v.

Is this normal?

I hope someone could answer my questions and might offer some advise what to do until the legal dispute is solved and may have some experience if i should be worried about possible battery or system damage or not. Further background Information: the victron expert my contractual partner added to the system for customizing etc quitted the service since they changed settings without my konwledge which heated the solar chargers up to 56 degrees... / Ich hoffe hier kann jemand meine Fragen beantworten und hat vielleicht noch einen Rat für mich oder Erfahrung mit diesen Meldungen und weiss ob ich mir Sorgen machen muss um potentielle Schäden an der Batterie oder der Anlage.

Erroneous Readings: >700A Idle consumption, only 7.1V (Multi-meter confirmed 13.8V)

I have a 12V 2 batteries in parallel system with two revolution power lithium 60Ah batteries with 1m of 2B&S cable running from the positive to a circuit breaker then load. The Victron shunt probe (Supply cable) is connected to the line side of the circuit breaker (I.e. always on and before any load). All load, charger and earth are connected to the correct side of the shunt with only both batteries connected to the other side.

All load components are working normally and voltage is as expected around 13V however my Victron BMV712 is only reading 7V and says that there is an idle draw of over 700A, This is definitely false.

I've tried factory reset and linking to my phone to update firmware, the errors persist.

Any Ideas what's going on or if I've done anything wrong? is the unit just faulty?

Multiplus temperature problem

I have a 12/3000/120 multiplus inverter charger linked to a 345ah Rolls agm housebank and start battery in a yacht.

The charger was set at 60amps by the installer. Year one in the uk it worked perfectly. Last year in Southern Brittany the overheating link would occasionally blink, even when the batteries were not warm to the touch. It was warmer in Southern Brittany.

This year in Galicia, NW Spain, temperatures have recently risen and I am getting this problem again, but for the last two days turning off for a while and back on again is not clearing the problem - but it has been over 30c in the boat.

My question is this - is the temperature sensor function programmable and if so could the setting have been set too low?

Or - could this be a faulty sensor?

If the problem is a programming setting, could I reset it? I recall that the installer had to download software onto his laptop to enable him to configure the charge settings.

Many thanks in advance for any advice preferred!

this was during normal operation of our camping car. whilst no change was done to anything...
i checked the "real" battery voltage using a DMO and it was 13.x volt.
i quickly inspected all the cabling, but all seemed correct. (and all other values including current from the shunt looked correct..
I then did a reset to factory settings and the voltage was back to normal display (but it started with 100% capacity..) .
It seems to me like a software problem as the only thing i did to resolve it was a factory reset...
