How do I set the Quatro 8000 to shut down at 30% SOC on a completely off grid system. It is connected to 2 SmartSolars and 2 Freedom Won batteries of each 15/11 kWh. There are no assistants on the system. I tried to set the shut down with VEConnect on the Quatro but it goes down to below 10% SOC before shutting down.

I've been reading for a while to see whether the above is possible, and if so how to accomplish it with what is already installed.

Currently I have a Smart MPPT100/30 and the BMV-712 (and a 12/30 charger, that won't talk to the other two...) installed in a case along with a set of 3 x 130Ah AGM batteries. There's a real chance the temperature may become higher than desirable so I need to be able to switch on a fan to get some air through the case.

Basically, can I switch on that small fan without adding anything more or do I need to add in something like a temp sensor to the 712 to accomplish this? I'm not looking for accurate temperature data, just turn the fan on when it's too warm and turn off when it's all cool enough without adding anything unnecessary.

I've got an idea that it might be possible, but I haven't figured out how to do it yet and hope someone out there already knows how it is done and save me some angst working it out for myself.

And if possible, can someone quickly tell me if the 'relay' on the 712 can switch something like a <1A load, or if I need to add in a proper relay. Maybe I've missed that on the read throughs of the manual...

Thanks in advance, I hope.

(And if no answers I'll find out for myself soon enough. Would very much like to get back to it with a plan rather than a hope/dream.)

Hello,

is it possible to read out the internal multiplus temperature?

i need it because i have the multiplus in a case because of heavy noises.

so i would like to start external fans with this temperature.

best regards

For past month my smartsolar is starting a newday in the history at around 1.30 in the afternoon. This happens even though the batteries are still bulk charging. I've reset the mppt via the Bluetooth app but the problem persists. Any suggestions how to get the newday to start at sunrise like it should?

What does new feature Switch "Inverter Only" actually mean on Multiplus/ Quattro? Does it mean ignor Grid or Generator? It is just opposite to Charger off ?

I have problem to charge six 2v batteries connected serial that give 12 v . There are 270Ah batteries. I have MPPT 75\15 charger. Since I am from Montenegro we have a plenty of Sun. OK not this year but still in cloudy weather I get 15.16v from solar panel on sunny it goes up to 20v . I use this for charging batteries for sea light that has 20w light. Still my battery drains. This sea light is not close to me so I can not check it regularly but it happens on 15-16 v from solar to not have charging at all. What is the problem. I do not have a bluetoothe dongle. Please help I am tired of driving to sea light once a week to charge drained batteries with generator

Isolation Transformer 3600W

Has anyone else had this problem

would be nice if I could get a full circuit diagram

but to my understanding there should be no electrical path between Boat PE and shore

Good Day

Please could I ask for some guidance / advice here.

I'm upgrading my existing system from 2 x 5kw Axpert inverters to a Quatrro 10000va.

My existing array is potentially 7840w - I don't want to have to lose any panels, and or have to add any more panels.

From my existing system, I already have an array of 28 x 280w monocrystalline panels. They are divided into 4 strings of 7 panels each. I've used the Victron mppt calculator, and I'm getting an answer of the SmartSolar MPPT 250/100 MC4.

My panel specs are as follows:

1. Vmp = 31.4v
2. Imp = 8.96A
3. Voc = 39.1V
4. Isc = 9.50A
5. Eff = 17.2%
6. Temp coefficient of Voc = -0.33%/c
7. Temp coefficient of Isc = 0.059%/c

My questions are:

1. If I keep my strings as 7 x 39.1Voc = 273.7 (I'm not taking any inefficiencies into account yet), do I potentiely risk running to much voltage into my charge controller? Should I rather re-string my array as follows 7 strings of 4 panels which would be then 4 x 39.1Voc = 156.4v?
2. Do I need two charge controllers to compensate for the amperage? I'm running 4 x 2.4Kwh pylontech batteries on a 48v system.

Many thanks in advance

When can i say that batteries are full? When SOC are 100% or when charged power(amps) are close to zero? See pitcure

Hello! I have Multiplus 24/5000, batteries, and a Fronius Primo 3.0 connected on the Ac output. I recentrly conneccted a Color Control GX to the system. The problem is that the Color control cannot show the AC LOADS correctly. When the solar power produced by the PV panels is bigger than the AC loads the Color Control shows that the Ac loads is ZERO. The calculation of the energy returing t the grid is also wrong. It becomes almost the double of the PV production. When the solar panel energy is smaller than the Ac loads (or Fronius is OFF), all things appear correctly.I had the HUB2 ver3 installed. I changed it to ESS but still the same problem. I changed it to PV support still the same problem.

Hi I'm Marian
My off-grid installation consists of: 
Inverter MultiPlus 12/3000 / 120-50 Firmware version 465;
Venus GX Firmware version v2.33;
Battery Monitor BMV-700 Firmware version v3.10; 
Controller Xantrax MMPT60x150; 8 panel 200W
PV Inverter Fronius Primo6.0-1; 15 panel 320W. 

1. When installing ESS assisant whatever it is in VE config 3 is not found in VRM.
 Why? What's wrong? 
2. How do I disable grid code selection Germany? I accidentally entered without a password and I cannot unblock grid Germany anymore. 
I attach the screens with my settings.
Thanks

Hi,

I just finished an installation of three 5kVA Quattros in threephase configuration and a 380Ah AGM batterybank supervised by a Venus GX.

I'm using the Lynx shunt and PowerIn/Distribution.

When i configured the ESS to always keep batteries charged, one of the quattros started to make a strange noise. Is this normal behaviour or sould i be worried?

I would also like to know how to get the SOC visable in remote console, i believed the Lynx shunt would do this automatically, but it doesnt.

As of now i have ESS mode Optimized (with BatteryLife) configured and minimum SOC is 80%.

The LEDs that are on now is Mains On, Absorption and Inverter on, guess that is normal?

Kind Regards

M

Good morning,

we are challenging some big data consumption on our differents sites.

I have found the Q18 : What is the data usage of the Color Control GX, but it does not answer all my question.

We have 2 differents type of site :

Model A : Color Control GX + QUattro 48/15000 + BMV-702 + Blue solar Charger MPPT 150/85

Model B : Colo Control GX + QUattro 48/15000 + PV Inverter Fronius Symo 12.5-3M

On our side, the consumption of data between our 2 models is more then X2 and we would like to understand if it can be link to our Victron technology , as the site is not synchronizing regularly due to our lack of data.

Second question : Firmware update mentionned in the Q18 ; how can we be awarded of those update and weight in MB ?

Thanks a lot

Hello,

I am trying to use a Battery Protect with my travel trailer. The issue is the manual says not to reverse the current from OUT to IN. My travel trailer has a DC converter/charger on board. So when I am connected to short power, the battery will charge. When I am not connected to shore power, the travel trailer will use the battery power. So I thought the solution was to use use three Battery Protects, a 225A for the inverter I also have in there, then two 65A's for the trailer, The trailer 12v load panel with the converter/charger would be connected to the IN on one 65BP (referred to as B65P1) and OUT on the other 65BP (referred to as 65BP2). When I am connected to shore power, I would turn on only the 65BP1. When I am not connected to shore power, it would turn on 65BP2. (See diagram)

The issue: When I am connected to shore power, the BP2 eventually shows E3 and BP1 gets very warm. So I guess this won't work. So how does one use this in a travel trailer? It is very common in travel trailers and RVs to have this converter/charger.

Any help would be appreciated.

Portal access via andriod app is fine however windows login rejects me with a red 'Login Required' message! Any suggestions?

Hi I have a Victron MultiPlus 48/5000/70-100 used in a utility backup solution, which has been working fine. Recently I received two alarm notifications per email: 'Overload L1 on VE.Bus System' and 'High discharge current warning on Battery Monitor', followed by two emails 1 minute later: 'High discharge current warning cleared on Battery Monitor' and 'Overload L1 cleared on VE.Bus System'. Is this something to be concerned about? Have never had them before. Many thanks

Will it show the temperature/Voltage in the VRM portal?

..if i link the smart battery sense to BMV-712 to Ve.Smart Networking

..if i used wire temperature sensor to the Stater Battery

Did an App update on my Victron Connect app and then when i went in it found the inverter as normal but then said I needed to do an Firmware update on the dongle...

I click on the UPDATE button but nothing happens.
Currently just leaving it for about an hour but still nothing.
It did an update quickly when I first bought it and updated.

Can anyone help me as I cannot monitor my inverter or use it remotely via the dongle and I need to!

CheersMat

I have a SmartSolar 75/15 here and im powering it for a test from a bench power supply. The power supply has a max voltage of 20v, but my batteries are 24v. It's not attempting to draw any current with this configuration.

I was under the impression from some other forum posts that it was able to step up the voltage to charge the batteries. Is this not true? Not a huge deal if it cant just an annoyance that I will have to work around.

Greetings,

Currently having issues updating Smartsolar MPPT 75/15's with app version v5.14. The VictronConnect App freezes on the update screen when connecting to the regulator and does not allow connection or update. I have managed to update regulators using the older version of the app (v5.13) of which then allows devices with the current v5.14 to connect to regulator.

Is anyone else experiencing this issue?

Many Thanks,

Adam

I have 3 of these controllers connected to separate 100 watt panels. At 4pm in the Bahamas with good light battery v is at 12.5 with less than 3 amps coming in. Never in the day was the bank of 4 GC-2s near full voltage.

Both lights are always flashing the same on all 3 controllers (2x/sec) whenever I look. All controllers are wired direct to the main panel switch and not direct to the bank if that might matter.

I am looking for an easy answer or at least be able to rule out some possibilities.

Thx

My MPPT 100/30 firmware updated, but the firmware for the Smart Battery Sense will not allow me to update it. VictronConnect will go to the screen with the update button, but the button is not active and the screen freezes.

HI guys,

Can someone with expertise with the Argofet help me, I want to add an Argofet to split charge my VRSLA start battery and my LFP house bank. Easy so far. I want to connect an MPPT controller to the input of the FET and utilize the alternator energize circuit to tell the MPPT that there is voltage. The solar controller needs to see voltage at the battery terminals or it wont start charging.

This is what I had in mind, will it work?

The following is from Victron ArgoFet documentation...

Alternator energize input
Some alternators need DC voltage on the B+ output to start charging.
Obviously, DC will be present when the alternator is directly connected to
a battery. Inserting a Diode or FET splitter will however prevent any
return voltage/current from the batteries to the B+, and the alternator will
not start.
The new Argofet isolators have a special current limited energize input
that will power the B+ when the engine run/stop switch is closed.

Have connected a 5KW Honda generator and after the power line on a Multiplus 48/5000, and in both cases, the batteries start to discharge. Have checked all connections of Multiplus and BMV with the suppliers and, everything seems normal. I'm off-grid and have 8 Vicron 220AH batteries. Can someone help? Thanks.

Is it possible to have the MPPT not starting a new charge cycle every day? In fact i only want to start a new cycle if the voltage drops below the re-bulk offset. This to save my LFP batteries when there are no power consumers since they don't like te be at high SOC for longer time.

How is this taken care of with victron lithium batteries? I assume, since they have the same chemestry, they also don't like to sit at 100%soc for a longer time?

Hi, due to some unexpected water damage, my circuit board for my shunt has been destroyed.

Where can I buy a new PCB? The shunt itself is fine.

Hi Seems load output on my MPPT 100/20 not working correctly after this last update done today V1.46 I updated both the 100/20 and my BMV 712 V4.03 and strange things are going on with the load output of the MPPT. I use it to remote power on my Victron inverter so if the battery is low it switches off.

Every time I connect to the MPPT via the VictronConnect program to monitor them via usb it turns the load output off then starts to cycle on and off every few minutes.

Been working fine for a year + I tried my user def algorithm that's set to off 11.8v and on 13.8v my currently battery is 98% SOC at 13.4v under full load when output is on. The a few minutes later the output turn off there is no way it going as low as 11.8v.

Tried presets con1 and con2 both show the same problem only one that seems to keep load output on is batterylife.

Going in and out of the VictronConnect on the PC causes the load output to switch every time too from on to off then back on. Also seeming loads of VictronConnect program lockups and crashes.

Need some help can't run my system at all like this.

Mike

If so, is it ok to go with a 50am even if I will mostly plug into 15amp shore?

(We will have 200ah lithium @24v and 1600w solar)

I read a discussion topic on this board that stated that the bluetooth enable ve.direct mppt controllers were due to get a synchronization feature a while back. Did this ever happen? If not, is it still being worked on?

Thanks
