Hello,

In 24v system, with 4 lithium batteries does the order of the battery interconnection with M8 circular connector matter?

Thank you!

Hi Everyone,

I recently got a 100Ah smart battery. On initial receiving the battery before i took it out of the box cell #2 and #3 were 0.3 Volt lower than the Cells #1 and #4.

This was a bigger difference than i expected on a brand new premium battery but I figured it was within tolerance.

I've ran the battery on a very slow charge and got all cells balanced to within 0.01 V.

I've used the battery a for one small discharge test of maybe 15 or 20% taken out of the batteries.

let the charger recharge back up to 100% and it was balanced within 0.1V across all cells after the charger went into float.

I've now left the battery and charger in float for 2 days and I'm back to a cell voltage difference of 0.05 V in just 2 days with no load on the battery at all.

0.05 V in-balance in 2 days with no load looks very poor.

This worries me. it looks like i might have a couple of bad cells.

Any thoughts?

Hey everyone,

I’m looking to get battery voltage data as a data point on the vrm portal, I can see the information on the 1hr chart but not on the daily or weekly information it only shows me battery capacity %age

as the BMV 712 only really give you an estimate battery capacity I like being able to look at battery voltage as data point as a fail safe. How could I make this happen? This is what I want to to see but across all points of time history.

Thanks in advance x

I use the PV-Inverter assistant in an off grid setup with lithium battery. At end of charge when the BMS doesn´t admit more charge, the battery voltage still rises more quickly than the Victron increases the frequency. This leads to an unstable system. Therefore I try to tune the frequency response of Victron by adjusting the values in the PV-Inverter assistant. Especially I would like to understand the effect of the values "PV inverter power" and "PV panel power" on the frequency regulation.

Just installed a new Centaur 12/30 on two LA banks totalling 300Ah . On applying 120vac the led lights, fan runs but outputs sit at battery voltage only. No charging happening. I’ve checked the wiring and disconnected and reconnected in the correct order according to the manual. No impact.

Any suggestions before I box it up and take it back?

Thanks!

I have 4 MPPT 75/15 working in parallel with the latest software allowing them to all go into the various modes at the same time. In the manual under equalization it says "The current is limited to 8% or 25% of the bulk current" would that be 25% of one controller as they are woking together or add the 4 together and take 25% of that?

thank you

Hi! Just installed a bmv-712 in my boat. Use to my 12V 100ah liPo4 Battery. I use it to my trollingmotor but don’t need to charge the battery after every session so I disconect it and Like-well disconect the +pol from the battery . When l conect it again to synchronize the battery to my bmv 712 it says 13,3 v but indicate to charge the battery so i can’t synchronize the bmv to the battery and set the right precent remaining.

Someone who have a clue?

I have just installed the Orion-tr dc dc charger 360W , I thought the alternator could handle the load but apparently it can't, the charger killed my starter battery in 5-10 min whist the engine was running, it cycled on and off as the voltage quickly went up and down. The starter battery is just a box standard lead acid battery and the battery bank im trying to charge is a lithium bank, changing the alternator is no small job to replace as it's pretty well integrated into the engine, so my question is ... is there custom firmware available to allow you to choose the charge rate ? I thought this option would have been there as standard but maybe it can be added in a future firmware release ?

Update * the alternator is rated at 60A

Hi Guys/Girls :)

I am new to the victron community, I just aquired a bluesolar MPPT 100/50 and VE.direct bluetooth dongle.

I am trying to set up the battery but I am confused as to what preset to use. can you please help, I have attached my battery specs below.

I have 8x of these batteries wired in parralel and the wiring is balanced :)

what is the cyclic charge? in my case does it mean absoption or equalization.

how shall I set the settings below:

- Maximum absorption time
- Rebulk Voltage offset
- Equalization voltage
- Equalization current percentage
- Automatic equalization
- Maximum Equalization duration
- Tail current
- Temp compensation

and the rest of the settings

I have attached the battery specs below as well as screent victron connect battery setting.

I will very much appreciate if you can help me with the preset.

Many thanks for your help :)

Hi There,

I have a Victron Quattro system that goes into "passthru" and then stays there for extended periods of time. I have noticed that this is somehow related to communication with the ET112 single phase grid meter which is connected to a color control gx.

Enabling and disabling the energy meter as well as restarting the color control solves the issue consistently.

Below is a list of components with the current firmware versions

Color Control GX - v2.54

5kVA Quattro - 2657430

Freedomwon Battery Monitor - v6.8

250/70 MPPT - v1.50

3.6kVA Fronius Inverter - 3.13.2-2

Please let me know if I'm missing something.

Best Regards

Riaan

I have a basic question - or confirmation

Is there a schematic of the L, E and Neutral wiring for the AC In and AC out. This is for the newer Multiplus 48v 1200 VA 13

It uses GST 18 male and female connector -

Can someone please anotate it on the diagram - just wanted to double check before I wire things up

Hi,

Is there a way of combining the eco mode and refrigerators with digital thermostat? I understand from a Facebook-group that mechanical thermostats work, but probably not a digital one.

Hi All, I have a camper that runs solar on the roof, and via a Smart DC DC Orion 24/24 - 17 charger in my truck camper. Currently these are not networked as I am driving along which does cause them to sometimes be in different charging states.

Posts on here have asked the question but have not been updated recently - when will the Orion DC DC chargers join the Victron Networked family?

I am very keen to have all devices working on the same charging algorithm. Is there a workaround with the Victron Dongle?

Does anyone know when these will be networkable?

Cheers

Hello people, I have 2 victron Phoenix 12/3000 I recently purchased for my boat. One wasn’t quite enough to handle my cooktop and oven if both running maxed out. I probably could have got by with just one but I like the thaught of redundancy. I’m still not sure if to run them parallel or on seperate ac circuits. If I parallel the units do they both have to be on to operate? Or if I’m not going to be using much power can I just turn the master on and leave the slave off? Just a thought I had and couldn’t find an answer in my reading so far

Cheers

I just installed an FET isolator and it seems to be working fine. Is it ok if when my boat is parked at the house I connect up a standard 12V battery charger to the isolator and charge both batteries at the same time just like the alternator would if the engine was running?

I purchased the dongle from a Victron rep. It works well when connected to my laptop. However the dongle power LED does not light when plugged into either USB port on the CCGX. I tried another CCGX, resulting with same no apparent dongle power. The CCGX works fine with all attached devices, and is powered by 24V from the coach battery system.

Hi

I need activate a auxiliary relay K2 in a quattro 24/5000/120 100-100 firmware 433, with a battery temp sensor , in the programable relay assistant, I don't find this option, is it possible do it with other metod ?

Hi,

I have the above Multiplus, BlueSolar MPPT 100/30, 2x200W/12V serial PVs, 2x200Ah/12V serial AGM batteries, Honda EU2200i generator and have the following questions about three settings:

1. If I have both the search mode and AES switched on, which is over-riding the other or can they work together?

1. For the 400Ah/24V battery set it doesn’t seem possible to set the maximum charge current as low as the generators continuous output 1800W/230V=7,8A. The lowest setting is 25% of something (percentage of what is still unclear? Maybe 100A x 25% = 25A?).

3. The input current limit can only be set to the following values:6,3A (1.4kVA at 230V),10A (2.3kVA at 230V),12A (2.8kVA at 230V),16A (3.7kVA at 230V),20A (4.6kVA at 230V), 25A (5.7kVA at 230V),30A (6.9kVA at 230V), 50A (11.5kVA at 230V). The question is how this setting affects the charging on different loads. It is clear that I should not have this setting to more than the generator’s continuous output power. But is it so, that 1) at no load the genset is charging with current of the setting (e.g. 6,3A), 2) when there is load up until the setting (6,3A), the load will be supplied 100% by the genset and the rest is used for charging and 3) when the limit setting (6,3A) is passed then the load will be covered by the genset AND the batteries and no charging will happen?

Thx.

I recently installed a solar panel on my RV, the Victron was installed last year and seemed to be working fine. Now with the solar it seems the settings are all messed up.

My solar charger has a boost voltage of 14.6 V and my RV Charge controller has an absorption of 13.6.

My batteries are 2x6v 235Ah batteries, I am just trying to figure out what are the best settings when both are used.

I have seen people say set the voltage to 14.1v and the tail current to 4% and set the charge time Higher like 15 min+. Any help would be greatly appreciated.

how does setting the voltage higher then the rv charge controller affect the BMW when the solar is not on but only the charge controller is used?

Thanks everyone

Hello.

We have purchased a Phoenix 24/5000 inverter in order to integrate it with our system using a VE.Bus to VE.CAN interface and a VE.CAN to NMEA2000 interface. Is this connection possible as we didn't receive anything in our CAN bus system. In what status we have to put the Remote Switch?

We know this connection is deprecated and we are going to use the VE.Bus to NMEA2000 interface instead.

Thanks in advance.

I have a sailing boat with BMV 712 connected to a service battery bank and a crank battery for the engine. The main battery bank which BMV is full monitoring is the service one with 460AH. I have a Perko switch where the two positives of the banks are connected. Where I turn my engine on and uses battery 2 bank on the switch I was supposed to see the alternator charge to this bank (I Have an Yanmar 29hp engine), which is not happening. I did not connect any alternator cable to the battery 2 bank where the BMV shunt is connected, where I think the problem resides in.

Can you help me and let me know what alternator cable I should have wired to the bus bar that connects to the shunt?

I see that Fischer Panda have established interfaces with Victron kit, but is the equivalent interface to DSE/Beta generators either available or in development? I am loathed to start developing one myself if this would be duplicating effort.

Is there a way of settting gen start for entering the night time period with fully charged battery? As well as set for overload and low battery ?

Hi,

We have a customer that's their Multiplus 2 occasionally(3 times in the last month) stops accepting the grid and then goes into overload and cuts out. Meaning they lose their emergency circuits, while the grid powered circuits stay on...the opposite of what we want.

When the overload takes place, there is not a lot of current being drawn through the inverter.

Has anyone experienced this?

Voltage and frequency input is normal.

Thanks Dean

Hallo, auf meinem Boot habe ich einen Phoenix-Lader 50 A und ein MultiPlus 12/70/1600 sowie ein MultiControl in Betrieb.Folgende Symptomatik ist aufgetreten: am MultiControll blinkte die Temperaturwarnung wiederholt 1x, 2x und 3x auf. Der Ladevorgang war auf der Stufe Absorption. Nach Erreichen der Float-Stufe schien alles wieder normal. Am Folgetag stellte ich fest, dass die Lader in der Stufe Float über 8 Stunden mit ca 8-12 A geladen haben. Frage: was hat das Blinken der Temperatur-Warnung zu bedeuten (Fehlercode?) und zerstört eine Stromstärke von 8-12A mir nicht die Batterien. die ja bereits voll geladen waren? Ich freue mich auf eure Antworten und Erfahrungen

BMV shows SOC at 94% and only used 19AH. Why is my voltage so low? Did I get bad batteries?

We have VE.bus smart dongel connect to Multiplus and we use VictronConnect to control and monitoring the Multiplus.

From time to time we can't turn off the Multiplus. Multiplus just does not react at all. Whoever VictronConnect show green as the MultiPlus should be off.

Any ideas what to do?

I installed a 48V 3000 Easysolar II GX in Feb this year, when I was commissioning the plant and setting it up on the portal we had an issue with the Wifi network from the Venus and for the life of me couldnt get it to come on again. Does anyone know what we can do to sort this out? I know on the Venus you can reset the wifi network but with the Easysolar its not easy to get to the Venus.
