Hello,

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

Thank you!

Smart Battery un-balancing zero load

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?

Venus gx VRM portal battery voltage data

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

PV Inverter assistant. What effect do the settings have on frequency regulation?

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.

Centaur not charging

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!

MPPT 75/15 bulk current

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

Orion dc dc charger

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

Quattro Inverter in Passthru

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.

Orion DC DC Charger - when will it be networkable?

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?

Phoenix 12/3000 parallel running individually

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

Adapted plans supporting performance optimizers?

Dear Victron-Team,

PV module performance optimiser get more and more meaning in difficult environments, but also in terms of emergency shoutdown for all PV modules.

Since Tigo is supported in the meantime by a series of inverter manufactures (e.g. Fronius, SMA, Solax, Growatt, Omron, Kostal, Sungrow, Schneider Electric, etc.), I would appreciate, if you could consider the support with Victron MPPTs on near term.

Are there already any plans contrary to your statement from 2019?

Multiplus 24/5000/120 settings: search mode, max charge current, input current limit

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.

Help with Victron 702 Settings Both RV charge controller and Solar used

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?

How to connect the alternator to the shunt bus bar for Victron BMV 712

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?

Multiplus 2 stops accepting the grid and then overloads ESS

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.
