Hello what size altenators are required to supply the inverter with enough power. We have 2 1000cca batteries.

Bonjour

I have MultiPlus Compact 12 | 2000 | 80-30 230V with BMV 702 and a Phoenix Multi Control. Till a month the Absorption & the Float orange ledlights are flashing all the time. Is this normal? Everything works well but I don't know why is it flashing like that. Thank's in advance.

Hi,

I have a multiplus 24/3000/70 connected to a pair of tesla modules.

The pack voltage has dropped to 20v and the multiplus won't charge anymore. Any suggestions as how to resolve this?

Thanks in advance

Hi All -

Is it possible that when you update the MPPT to the latest firmware that some of the battery settings can be reset to default?

I could be mistaken on what my settings were before but I am a pretty detailed person and wouldn't expect that I had my MPPT settings incorrect.

That said, I just upgraded my MPPT firmware to the latest, 2.19 or 1.42, (idk which one to reference) and I noticed that 2 of my settings were off:

1. The Temperature Compensation setting was set to -36.00mV/F, which I believe is the default. I would have had that set to -20.00mV/F as I have Lifeline AGM batteries.

2. The Maximum Absorption Time setting was set to 2H, when I would have had that setting to 6H.

Again, while very unlikely, there is a possibility that I set these to what I saw but I just wanted to check if I need to be checking my settings after every update.

Thanks,

Tom

Is it possible (or recommended) to use ESS in an OFF-GRID system for a household, using the following components:

• AGM Lead-Acid batteries (in a hybrid li-ion / lead-acid battery system) but the system can see only the lead-acid battery side. So it is typically like having an AGM battery ONLY connected to the inverter (in case if you are not familiar with Hybrid li-ion/lead-acid batteries setup).
• Quattro 120V / 5000 VA
• Genset connected on AC in 1 with LOM Type B
• 48 V DC system

This may be an academic question for the moment, however a customer is keen to have an energy meter approx 100m (and several walls) away from the CCGX and installation. The standard zigbee may not be enough; are there any known supported zigbee repeaters that might work for this purpose or a longer range, higher power unit? Alternatively would the ET112 RS485 signal support an RS485 wireless bridge? Thanks

Hello,

I am new to Victron Community and have done 6 Victron solar installations - all single phase.

I now have a 3 phase, 380V with 3 MultiPlus II's solar installation coming up and need to prepare myself properly. I have done extensive internet searches for training or "how to" video's in this regard, and found just 1 video and then the Victron Parallel & Three Phase VE.Bus Systems manual.

Don't know if my search term is incorrect, since there are many ways to write "3 phase", eg 3-phase, 3 phase, three phase, 3PH.

I would appreciate it if anyone can point me in the right direction, where I can find such videos.

Thank you very much!

Anyone else using a Tesla battery? I'm surprised to find that I can not turn on my inverter below 21.8V. Do I have to return this inverter?

The tesla battery is supposed to be 20% SOC at 19V, 100% SOC at 25V. Please help me utilize my full battery. Thanks.

i have set charge voltage and float voltage to rolls recommended voltages but i can not set the absorption time. i am in user defined setting. it should be 4.2 hrs and it is stuck on 6hrs.

any ideas please

Is there a way to connect the bmv 712 to either a bp220 or bp100 to stop charging when temperatures are above or below a lithium batteries charging specs? I currently have one bp220 in place to cut loads when voltage is too low. I'm planning to add a 2nd battery protect after the charge connector to stop charging. Any help will be greatly appreciated, thanks.

My Fan never comes on-

at what point / how / by what is the fan triggered?

How can it be diagnosed?

The casing literally gets too hot to comfortably touch,(*) I have had the intermittent Temp LED and on one day a constant Temp light.

If this where a laptop it would be going straight back to the manufacturer: If it is getting too hot - (for ANY reason) then the fan should come on - surely!

(*)This is NOT a ventilation/ load issue & the EasySolar < 2 months old

I use my new 100/20 smartsolar and I don't understand maximum and minimum values indicated using bluetooth on my phone.

please note that there is nothing connected to the battery only the smartsolar to charge battery. nothing is connected to the load output.

for instance, right now battery voltage is 13.6V

and for today, history indicates :

max battery voltage : 14.41V

min battery voltage : 10.99V

how can the max battery voltage be acheaved ? as battery is currently only 13.6V ???

the same for the minimum battery voltage : 10.99V.... how this value can be achieved ? during the night when there is no sun and the smartsolar is using current of the battery ? it would be insane...

Does it mean that my Pb battery is completely dead ?

As far for the min value there could be an explanation but I don't have any explanation for the 14.41V

is there a way to see voltage battery during the day with more precision ? by hour ?

Hello,

actuall my consumers are direct connected to the battery, not using the "load" from the charger.

Now I will change my cables and connect the consumer to the charger to see the consumptions etc.

Question:
Where is the measure? Plus or minus?

I think, Plus or Minus (one of them) from Solar, Battery and Load will be connected together (have a direct electric connection). In my case I only have the need to change one wire (plus or minus) and bring this wire to chargers "Load" (and the other can be still direct connected with the battery (plus or minus). And mot both from my consumers ...

Hi

After remotely from VRM upgrading SmartSolar to 1.42 my battery doesn’t get charged fully. It charges to example at 92% and today 89% and then just stops and only matches the solar yield to the DC consumption even when there is lots of sun.

I got an error “#68 Network misconfigured” from the SmartSolar after upgrade so I had to exclude it from the SmartNetwork. That is clearly show on the graphs as the big dip starting 2019-04-24.

Both times it has got back to SOC 99 or 100% was after a shutdown and power off whole system and starting it up again.

I have notice the BMV-712 in not correct in SQC and stated 100% when the battery is not. But the VenusGX is set to use Battery Monitor “Pylontech battery on CAN-bus”. Can it be the BMV that is still being in control of SOC in some way? SmartSolar is disconnected from the SmartNetwork but it still feels like it stops charging when BMV get near 100%

The system has been working very good until now.

I have checked the settings against https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

Pure DC system with 3500w PV and

VenusGX (2.33)

SmartSolar Charger MPPT 250/100 rev2 (1.42)

BMV-712 Smart (4.01)

Pylontech US2000B.

512 = Pylontech
260 = BMV-712 Smart

This is a remote location and I can only use VRM unless I take the trip there.

Dear people

I am preparing project for my master degree, and my subject is off-grid solar powered electric vehicle charger. I need your help to check my calculations. I am bulding 9kWh solar system which will aproximetly produce 54.23kW daily. This calculation is done with average daily sun hours 6.3h with Victron solar panel mono 360W (working with 85% of their max). I need to install 28 panells 7 in series and 4 in parallel directions. Each panell is producing 1.9kW daily. 28 panell produce 8.56 KW per hour. Can I put my system to work on 48V, if solar pannel max. power V is 38.4V ? and my batteries are working on 25.6V ? Second question is choosing right charge controller. SmartSolar MPPT charge controller 250/100 can handle 100A and 250V. If I connect my 28 panells in way that I described (7 in series and 4 in parallel) how many charge controllers I need to handle all this power from solar panells ?(With my calculations that system require 2 * 250/100 MPPT charge controllers). And my DC load is going for Level 2 EV charging with 7.7kWh and rest DC current for Lithium Iron Phosphate batteries charging through quattro hybrid inverter/charger. Thank you very much.

Kind regards

Hallo, ich habe meine Batterie durch zu hohe Ladespannung gekillt. Ich habe einen Quatro, einen BMV und einen MPPT und 6x280ah Batterien auf 24 Volt verbaut. Der Quatro lädt die Batterien über einen längeren Zeitraum mit bis 28,2 Volt. Der BMV schlägt dann immer Alarm zu hoher Batteriespannung. Ich habe gedacht, die Spannung ist nur während des Ladens und des BMV weiß das ja nicht und nach dem Laden geht die Spannung wieder runter und alles ist gut. Aber leider sind die Batterien nach einem Jahr zwar noch bei 25-26 Volt und mehr, aber wenn ich zuletzt Last , also den Backofen laufen hatte, sind sie sofort auf 22 Volt gefallen bin. Welche Einstellung muss ich vornehmen, dass die Spannung nicht wieder so hoch geht? Oder habe ich einen anderen Denkfehler Und es gibt eine Möglichkeit die 1 Jahr alten Batterien noch zu retten?

instead get phase one Live and phase two Live from the output of a changeover to feed Quattro AC 1 In and AC2 In respectively and save the cost of running multiple cables.

Please advice. being racking my brain all day long.

isolated system with quattro8k, AC and DC coupled chargers.freq shifting from 50.5-52.5hz,off at 53hz.(SMA inverters).at end of day freq stays stuck at 52.7hz through the night, failing to reset to 50hz, battery voltage is now 49,1V 82% SOC. turning on the generator resets the freq, but this is no real solution.suggestions?

Hi,

I run 2 pairs of 180W Victron solar panel with MPPT 75/15 for 7 years, and today while in absorption mode, one MPPT stopped charging. Inspection showed that 'solar minus' (third attachment after battery +, battery-) is burned. I also checked voltage of associated solar panel and was showing 13-14V instead of 40-42V which was shown on my other MPPT controller that is connected to another Victron solar panel).

MPPT 75/15 will have to be replaced but wonder what caused this 'event'. Ii appears solar panel malfunctioned and killed MPPT ? What can possibly cause that ?

After connected faulty solar panel to good MPPT for diagnosis, it appears I stuffed up the second MPPT 75/15 as well as it is now showing 0.01V, although second solar panel voltage is around 41, measured by instrument.

thanks heaps for any insight

On the panel that I purchased the individual breaker amperage is not clearly marked on the panel nor is it possible to see it on the breakers itself.

Can I assume that the amperages are as stated below from top to bottom?

In order for the system panel to control the backlight, where should I put the negative wire, as it is not clear on the diagram below nor on the panel itself?

I have two quattro 8kVA's in parallel set to export excess PV to grid. This is all DC-coupled PV.

This works well, but I'd like to confirm the limitations of the system.

I intend to expand the system.

1.) Is the combined export to grid capability of the quattro's 16 kW or 6.5kW x2 = 13 kW at present?

2.) Observing the 1:1 rule, if I add 16kW of PV inverter capability on the quattros' output is the new export capability now 1.) plus 16kW?

Thank you.

I have a parallel setup of Quattro 8000 and i would like to add a small 3.4kVA generator to my setup.

Being unable to use the AC inputs on the Quattros due to the current limiter being too high, i'm looking at another way to do it.

If I run the Quattros in inverter mode, and then connect the generator to the output through a hot bus synchroniser, this would frequency and phase match the generators output with the inverters before closing a solenoid to connect them.

I know this method works well for linking multiple generators together, but how does the Quattro respond to it? Will it just treat it like a AC coupled solar array?

I have just installed a Victron bmv 712 unit in my boat. Setup for house and started battery banks. The display shows voltage of main and auxillary batteries, but is giving a fixed amp and watt reading, both positive and both excessive, I have worked the setup program and consulted the manual, making sure all functions are turned on. I tried the synchronize and zero calibrate functions on both the head unit and phone and they do nothing. I did this with all input power shut off, batteries fully charged. Then applied fridge & other components to see the draw...no change. ie. it is not reading current or power. I tried reversing the negative battery terminals on the shunt...no change.

I see others have had similar problems but do not clearly see the answer. Is this a defective unit? Surely not the cable. I have not taken a photo of the shunt installation but will attach soon.

Thanks.

I have some 24v victron smart lifepo4 batteries to connect in series, i see in the manual it states they should be charged to 28.4 for volts for several hours just wondering how people are doing this? I have various chargers but i dont think i have one with a settable output voltage unless it has cell info e.g i have junsi smart chargers where it would need to see all the individual cell voltages i dont think this will be possible with victrons batteries. Any tips? Thanks Jack

Hi, I still receive different errors on my 3 phase Quattro system. Most of them have no effect but sometimes it causes the whole system to collapse resulting in failing my vessel propulsion system. Not nice on IJsselmeer under heavy windy conditions. :-(

Please note the screenshot I took from VRM portal.

Is there any way we can dive deeper into what is causing these problems? I’ve double checked cabling (even replaced some UTP cables), system settings, etc. One of the units has been replaced recently but these errors were there before. After the replaced unit, all units have been upgraded to recent firmware.

I have the idea that most (if not all) errors occur when the system is running on generator and is in absorption or in float state.

I have 800Ah of LiFePO4 batteries connected to a Pheonix 3K inverter running at standard settings of 230v/50Hz. I am attempting to run my French bought Bosch Serie 2 washing machine from the inverter. I get very inconsistent results. Sometimes the program will run through without problems, other times it will stick in the wash phase etc. Whenever I connect to mains electricity the machine works without fault. Without wishing to lead suggestions I have started to focus on the drain pump. I have a suspicion that it does not always manage to start up and as a result the "smart" washing machine stalls in it's logic. For example there are times when it will not enter the spin cycle and this would be logical if a drain cycle just before that has failed to initiate.

I am looking for ideas as to what may be causing my symptoms and what I can try to get around them. The machine is definitely a 50Hz item so I am loathe to try upping the frequency. Is my 'pure sine wave' Pheonix producing a clean waveform? .... I do not have access to an oscilloscope to check. I'm considering buying a 'Bosch compatible' drain pump to see if subtle manufacturing differences may alter the outcome. Any ideas gratefully received.

Hi people, I installed a Multiplus II 48/3000/35 with a 2.4kw pylontech battery and a smart solar charger fed by 3.2kwh of PV panels. During installation I first had the PV to Smart Solar charger to Pylontech batteries connected and the battery was charged thru the expected cycle of Bulk then Absorption and finally Float. This cycle repeated for many days and all seemed in order. Once the Multiplus was connected the charging cycle has changed to Bulk and then Absorption. It never reaches float any more, does not matter which charging MODE setting in ESS I choose. I also notice from the downloaded .xls kwh files that the power delivered/fed from the battery is about 18% of the power fed to the battery either via grid or PV. not sure if this is normal. I know this is a brief explanation, happy to supply more detail if required.

Thanks

Hallo !

For the second time this summer I have lost data in VRM - no data on dashboard or in advanced

(the system itself works fine :-)

The first time was in July, and I found out that it probably was caused by an update on July 14th.

-see post from that issue here:

https://community.victronenergy.com/questions/24318/missing-data-history-in-vrm-easysolar-24-3kva-july.html

The same thing happened on the 10th of august, which i rectified on 14th of august.
(I am not sure, but I may have switched og the main "output" switch on the 10th of August -but this shouldnt affect the CCGX/VRM /data history....?)

Both times I have rebooted the system (on site) and solved the problem.

(The system is on an island away from where I live (in Oslo) I have no means of checking on the system when I am not there.)

Very curious to why this happens....
