Good day everyone, am trying to limit my cabling length runs on a proposed installation, so i thought instead of getting GEN for AC1 In and GRID for AC2 In ..

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.

What is the Modbus TCP unit ID for the Multiplus II GX ?

Please i need an explanation as to what VE.bus inverter state "255" mean and also what MPPT state "131" is?

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

Using the MultiPlus on a small scale Solar installation.

Configured in inverter mode only - operating with 12V (nominal) battery input and AC output to run LED lighting.

It's been operating for 4 months without problem.

The unit then failed. There isn't any LED indication or AC output.

The unit has been left switched off for 30 minutes in an attempt to 'reset' it but is still unresponsive.

The internal fuse is intact and the manual doesn't suggest there is a user replaceable fuse in the enclosure.

I am very disappointed with this early failure. And espectially given the unit isn't operating anywhere close to it's rated maximum power output or on a continuous basis.

Are there any more diagnostic steps that can be run or is this a write-off of almost new equipment?

Six months ago, following multiple user complaints, I posted this, outlining how Victron MPPT controllers consistently fail to fully charge batteries in intermittent sun, due to a bug in their "smart" Absorption timer algorithm.

"Fast" forward to last week, and finally a supposed solution is given in terms of an update to Firmware 1.42.

Except it's not.

Nothing has changed with v1.42 at all. The controller is still resetting to its shortest absorption period every time a cloud goes over, and dropping to float when the batteries are desperate for charge. And yes - I manually ensured the battery V was under 12V every sunrise, and I did isolate all loads during the day for these tests - that difference in Amps between the app and the Trimetric is just Victron's apparently poor accuracy (another problem in its own right).


This isn't some obscure, niche problem. This is core function - reliably controlling the absorption stage length is the fundamental point of a controller. It's been reported again, and again, and again, and again, and again, and again. We have a suspected case where it's ruined someone's batteries as a result. For it to take six months for this to be addressed, while adding pointless gimmick charts to the app instead, was poor enough. For it to now turn out to be a non-solution is unacceptable.

I'm addressing this squarely at you @mvader (Victron Energy Staff). You promised this was being fixed when I first bought it up. Your response here determines whether I take this unit back for a refund.

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

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

Hello,

Is it possible to use the VE. Can Resistive Tank Sender Adapter in a system using a BYD battery if there is a Venus GX in the system?

Also has the second relay on the Venus been made available for use yet?

Thanks

Is it possible to connect 5 smart solar charge controllers and 1 BMV to Color Control GX device??

Hello,

I’m wondering if it’s possible to use Quattro/Multiplus together with Fronius inverter + Fronius Smartmeter and avoiding frequency shifting. That concerns off-grid system. For on-grid systems, a combination Multi/Quattro + Fronius inverter is much stable and operating seamlessly, no doubt.

What I noticed, the frequency shifting is not as much effective or responsive as Fronius Smartmeter can manage energy generation.

Brining the Fronius Inverter from a generating status to a zero-feed point is done in less than 5.0 sec for a wide levels of energy production.

I understand, that there are a great number of different conditions to be met, but the question is if at least, theoretically, such a scheme may correctly operate.

Thanks in advance,

Vyacheslav

After only 6 weeks my 5kVA Multiplus II has failed!!! My installer has taken the faulty unit into the distributor who has submitted all the warranty info. The disappointing thing is the time this all takes and so far I have no idea when a replacement will be coming. It is kind of critical when you are relying on power. Can this process be streamlined, maybe have a swap out or something similar?

Also, I have heard that the Multiplus II is not as reliable as the Mulitplus. Is this true?

17Perth_20190819-1000_to_20190819-1507 1.pdfI am getting error in VRM data for the inverter but no code. Normally during the night i would get low pv error codes and the like. but in the day every now and then i have Error but no code.

Multi with a Fronius Primo on the AC out 1. grid. the Fronius is on the router via an ethernet cable. so comms should not be an issue? how can i track down this error message?

attached a sample of data.

I would like to know if there is any advantage when installing 3 panels in parallel and parallel them at the MPPT versus parallel them at the panels and bring down only 2 wires instead of 6. I'm not looking for cost advantage just for technical advantage/dis-advantage. Both setups of course done with the appropriate cable size.

What are the ambient temperature limits for the VE.Bus Smart Dongle?

Cannot find any data here:

Please help.

Hi,

Anybody has information about what's the maximum string voltage of LFP- Smart 25,6/200 connected in series. I couldn't find it anywhere in the documentation.

I assume we won't be using Lynx since it's limited to 48VDC (if remember well) nor Quattro, etc.

KR,

Lucas

not working at all , only 12v dc connected - all 8 leds flash on both settings.

any idea what to do?

Hi all,

my CCGX actually runs firmware 2.18. Now I want to update to the newest version via Internet but I am getting always the following Error and loud Beeps after the updating process has finished: "Hardware problem detected #42; Alarm; Storage is corrupt on this device."

It looks like that the CCGX is running fine after the update, but I cannot reset this error. The only solution for me is to use my backup firmware and downgrade to my previous Version 2.18.

I suggest, I cannot update because at least one of my Linux partition of the CCGX is faulty.

Is there a way to fully reset the CCGX or to format all of the CCGX partitions?

Best regardes

Hi, I have some concerns about power quality when the generator is on.

The generator is manually turn on every night for about 20 minutes. As you can see from the picture attached the inverter VE.BUS State changes continuously and the output power and current are fluctuating.

My load is very stable (300W). It is very important to have a good power quality for my loads.

Because of fluctuating VE.BUS states the generator does not automatically stop with VS setting.

I have a client that wanted a Multiplus 48/5000 but he wants to limit the inverters output power to 3000W. I did this under ESS, I am then however not able to use "Keep Batteries Charged" as the limited output is not available under this option.

The problem that I have is that the system does not have PV. Is there another option besides scheduled charging to get the batteries to charge from the grid?

My Multiplus 24/3000/70 switches on, but then after a few seconds flags an overload error.

I have already upgraded the firmware to 1941209 and executed the calibration program as specified by Victron. All was implemented successfully.

It happens with, or without, any load. I have not added any 'assistants' yet.

Anyone have any idea how to reset/cure this issue?

Should I use the BMV-700 device in my system that contains 3 quatrros, 4 charge controllers, CCGX?? or is it ok NOT to use the BMV-700 ?

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 was curious what the difference between these modes are and which would I would use to connect my BMV-712 so that I could shut it off when it reaches a certain SOC.

I'd assume relay mode is the one I want but I am not quite sure.

My multiplus compact is going straight to passthrough instead of going to charge mode. The batteries are not fully charged, so I think it should go to bulk. If I reset it,it does goes to bulk.

Please confirm that my wiring on left for my bank works.

Trying to work out if my green, orange and blue lines (and single red and black lines) match what the manual suggests. The series and midpoints links don’t allow connecting midway on cable, so I placed on one side. For red and black, use same terminals as inverter.

1, 2 and 3 (blue) are the 3 battery balancers.
