I have a Victron Multiplus 48V/5000VA newly installed which charges correctly the batteries with 2000W of solar and also à 6kW desiel generator.

When the 2kW pump starts and the batteries are mostly charged everything works fine. Today with the batteries at 50%, when the pump is on the Multiplus stays on charge for less than a minute, then stops, then restarts, then stops, then restarts, then stops.

If I stop the pump the charger works correctly, but i need the pump to run and to charge the batteries at the same time. When on charge I have 1995W charging the batteries, and 2251w going to the pump, The group seems to be running fine. But the Multiplus switches on and off non stop. When the group is off, the charge to the battery goes up to between 2200W and 2800W.

Should the multiplus auto-limit the energy used to charge the batteries, or do I need to limit the charge. There is a color control installed.

The problem is the client is 600km from me and I'm not looking forward to driving across the country to change a setting on the inverter, but perhaps I will need to.

Cheers,

Jay

This screen shot is from: Manual-Quattro-5k-120V-(firmware-xxxx4xx)a-EN-ES

The main Question is that now there is contradiction in description how the Search mode works. first is say "no-load" then it say you can adjust the "shut down" and "Turn on" levels.

What we are facing as problem is that in reality Search mode will only be active if there is litarly ZERO LOAD AC on the inverter, so what is the need for the load levels defination?!!

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 was wondering why my battery was empty and checked the setup again. Turns out that the charger doesn't seem to show and handle the wattage that is actally put out by the panels:

Charger display: 16v 1.8A

Multimeter readings: 30v 3.4A (measured on the disconnected panel cables)

How is this possible? (The battery is not full, and also pluging in a laptop or something doesn't increase the reading.)

Could this have to do with a firmware update lately? If yes, how can I roll back the firmware?

Thank you

I am adding a balancer to my battery system and want to clarify the wiring set up. I have a 24v 440ah configuration with 4 220ah gel cells. It is now wired with bussbars as recommended by Victron. Looking at the diagram in the balancer install sheet, it appears that the Common connection is simply wired into the midpoint circuit in the bank with the pos and neg terminals connected at the bussbars. Am I interpreting it correctly?

If this is the correct wiring set up, what is the actual balancing provided by the unit? Does it balance across the 2 series connected 24v cells only?

We are trying to get the ACout 2 relay work as "deveriable" load controller, the issue we are facing is that we need the following condition to happen in AND not OR logic to activate our water-heater so we can make sure that we are

1- Not affecting the batteries absorption cycle by sucking current from it during Absorbution, which will be the case if we use ONLY a voltage set point.

2- Create a very narrow operation window for the deveriable load to work in

Is there any possibility to make a programmable relay logic conditions in AND not OR?

This new version of "REC-ABMS for Victron CCGX" communicates with a GX Device using CAN. It sends Max Charge Current & Voltage and Max Discharge Current along with Battery Voltage, Temp & SOC. The GX Device uses DVCC & SVS to control all Inverter / Charger & MPPT Solar controllers to comply with the charging / discharging limits. Ok, so that sounds good, huh? But I also want to have contactors set to voltage levels in case the CAN bus goes down.

The previous version of the BMS suggested just the traditional two contactors - HVD & LVD to provide High Voltage Disconnect of the charge bus and Low Voltage Disconnect of the DC load bus.

But this version offers a Main Contactor for both HVD & LVD for Victron inverter / charger devices. And another Contactor expected to be used for HVD on non-Victron Charging sources. And though it is not shown in this diagram, I am sure they expected a third contactor for LVD to disconnect DC Loads.

[image]

Is this genius or overkill?

I questioned the new functionality, and the manufacturer offered to disable it to make it functionally equivalent to the old version. But I am an Engineer, so I tend to think "here is a Solution, now lets go find a Problem..."

Any thoughts appreciated.....

P.S. And....

I was expecting the fail-safe MultiPlus Inverter/Charger control to be made with a Charge Control signal to AUX1 and Discharge Control to T1 with the Assistant loaded "Two wire BMS (016A)"...

But they are suggesting Charge Control using the Assistant "Input Current Limit Control (0142)" and the AUX1 signal. And programming the Inverter's DC Input Low Shutdown voltage for Discharge Control.

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!

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.

Hi pros,

My isolation transformer 3600 is configured for 230V input and 230V output but still delivers 115V output even though the jumpers are in the right place. This malfunction occurred suddenly after years of proper function. I checked the jumpers to verify they and the pins are in good shape. I suspect some other component is worn out. Any clues?

I'm installing a multiplus 12/3000 with v.net battery controller and blue power panel. System appears to be functioning properly but the overview screen gives me a consistent 9-10 amp drain even with no load. By that I mean completely disconnecting any loads from the battery switches forward. Anyone have a suggestion? 2nd Question. Do I really need that V.net battery monitor box between the Multiplus and Blue Power Panel? Multiplus has all the same connections as the V.net box. The system came to us as a package. I'm hundreds of miles from the nearest dealer and fresh out of ideas.

Not sure where to ask this, but does VE take product suggestions?

If so, a MPPT SmartSolar with 24V PoE out - similar to the PoE solar chargers sold by MSTronic/Tycon Power.

I've been using the 75/15 charger for years now but switched my remote internet gear and need 24V PoE. I'd like to have kept the VE gear, but having a passive injector and junk in my electrical box isn't ideal.

I have a Quattro 48/5000, a Bluesolar MPPT, and a Batrium BMS hooked into the Color Control and when I go to select the limit for AC input current, it is greyed out and says the following:

"This setting is disabled. Possible reasons are "Overruled by remote" is not enabled, or and assistant is preventing the adjustment. Please, check the inverter configuration with VEConfigure"

How do I change the "Overruled by remote" setting? It sounds like I might need to buy the adaptor to connect my computer to the CCGX so I can run VEConfigure on the Quattro and enable "Overruled by remote" on the Quattro.

Am I right with this thinking or is there some other (better) way of doing this?

Thanks!

Hello Guys,

I hope you are doing fine. I have some issues with my installation. I have a 3-phase backup system of quattros and a solar inverter connected at the output of the quattros. AC input of quattros is connected to the grid and feed-in is allowed.

Please have a look at these two pictures

[image]

Here AC-in power = - 4761 W

[image]

But in the menu, AC-in power = - 2324 W

Why the two values are very different? -4761 W is more than the double of - 2324! And I thing -2324 is the correct value as solar production is 2580W and power going into batteries is 216W, then the surplus feed-in energy must be around 2580 - 216 - power loss in quattro.

Thanks for your answer.

I have a MultiPlus C12/1600/70 and 200AH LiFePO4 battery system in a caravan. When not travelling, the caravan lives in a shed so solar panels provide no charge and I leave the MultiPlus running in charger mode. I have some small PV panels on the shed roof but insufficient to keep the battery charge. There are a few DC loads on the battery and nothing on the AC side of the inverter.

With the charger running the battery was sitting at 100% SoC for extended periods and I believe that is not good for lithiums. So I explored Ignore AC function in Virtual Switch and after a bit of fiddling with thresholds the battery now cycles down to about 25% then the charger kicks in and recharges it. Perfect. Exactly how I wanted it to behave - use whatever PV power is available and only use grid power when necessary.

However I realised this configuration works against us when travelling because we DO want the charger to be able to get the battery as full as possible - eg if we stop overnight on a powered site (especially in bad weather and low SoC), we want the charger to fully recharge the battery from the grid, not wait until it drops to 20-30%. In other words when travelling, we need to disable the Virtual Switch configuration (that works so well at home) and have the charger run whenever grid (or generator) power is available.

I know I can (and do) change this in VE Config but I wonder if there's another way without having to fire up my laptop and Mk3? I looked at the options within Virtual Switch but can't see anything that could be triggered manually (eg with a switch). The MultiPlusC has no aux input so that was a dead end. Can anyone suggest a solution I've missed?

Ideally it would be nice to have this available via Victron Connect and VE.Bus dongle - eg the ability top remotely enable/disable a VS configuration. Feature request??

Any suggestions or advice greatly appreciated.

Cheers

Phil

When programming 48V off grid systems with lithium batteries, I have found that the the 'DC input low restart' value's minimum 4V above the 'DC input low shutdown' voltage to be way too high.

My feeling is that this 4V margin is intended for lead-acid batteries, but it is not suitable for the much narrower operating voltage range that many lithium batteries have these days.

It is important to have low voltage shutdown set correctly to protect the batteries from over discharge, however, if this does occur the system won't restart again until the batteries are almost full!

I have also found this to be problematic in the event that a system is at a partial SOC (say 40% for example) and it is shut down manually for maintenance reasons. In the process of shutting the system down the inverter experiences a 'DC input low shutdown' voltage (momentarily before it dies). Then when the battery is reconnected the inverter won't turn on until it reaches the 'DC input low restart' voltage which corresponds to a SOC much higher than 40%.

~~~

Another feature that would be nice would be to be able to shut the inverter down on a set SOC outside of the ESS assistant. Or maybe this is already possible by way of virtual switch, which I haven't explored much yet??

The historical graphing data appears to be missing entirely ie none of the graphs are visible in the VRM. The only reasonable explanation I’ve been able to come up with is an issue on Victron’s end. Is everything operational at the moment?

Question as above. Does any amount of charging count as one cycle?

IE if you charged from 60% to 90% would that count as one cycle?

Or is a cycle only counted when you fully charge the battery to 100%

For instance yesterday my 300ah 24 v bank was at 56% so I ran the genset which charged at @149amps

The skylla tg cut out when the battery voltage reached 28.4v the 24 /3000/ 70 Phoenix inverter carried on charging but at much lower rate

But the app only showed 63% and stayed there. so on my thinking that was time to synchronise to 100%.

And that counts as one cycle?

Sorry if this is stupid question but I’ve just had the Lithium-LiFePO4 fitted and I am anxious to get the charging regime right

Hi,

Is it possible to have mulitple EM24 meters for the PV, looking to use 3 meters.

1. for the Grid

2. PV system 1

3. PV system 2

If you change the Modbus address on each meter to be unique with there be any issues using this with the CCGX or is it only capable of reading one of the meters as the PV system.

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

Hello ¡

I have 4 BMV-700 monitors with 4 different groups od batteries,

It is possible to associate a name to each device within the system summary, in order to identify them in the widgets. ?

The Load Output disconnect rules appear to never override the Streetlight function as the manual states they should.

The light turns on at sunset via the Streetlight function and turns off at sunrise fine. However, if get 2 or 3 cloudy days in a row (which isn't enough for my 45Ah repurposed AGM battery to supply a full night, without going below desired voltage threshold (after second night it is 11.4V,after third night it is 10.5V) it keeps turning on the light via the Streetlight function, even if the battery is below the "on" threshhold of 12.2V and leaves the load connected when it is below the "off" threshhold of 11.5V.

I hate to just assume that Load Output circuitry is damaged, as nothing has happened to the controller that would cause this. Anyone experienced this Load Output behavior on such a small load

I have two MultiPlus inverter/chargers already running ESS, but would like to add some additional charging capacity without the need for additional inverting. I am only interested in doing so if the other Victron charging equipment can be integrated with my Color Control GX, and ideally used with the "Scheduled Charging" feature of the ESS assistant. From what I am reading in the manuals, this does not appear to be possible however. Can anyone provide any input on this?

Silly question about a 2010 vintage inverter. I have two in parallel. The bottom left screw will not come out of either panel on either inverter. What is my dysfunctional brain missing?

I Have a Motorhome 12V system (2 x AGM 110AH) with 100W Solar via MPPT 75/15, Mains hookup Amperor 3 stage charger and a VSR split charge from the crank battery with standard alternator. There is also a BMV 700 & Venus GX. I am looking at ways to prolong the life cycle of the batteries after the current batteries lasted only one season. I have identified that the VSR split charge is a crude method of charging and could be improved with a battery to battery charge system. There are plenty on the market but I would prefer to use Victron products. I have found a Victron Energy Orion 7-35/12-3 Buck-Boost regulator that looks to be something like what I need but am unsure if it will give a charge quality comparable to say a Sterling Power 4 Stage Battery to Battery charger. I would be grateful for any advice or recommendations on the system and suitable products. Any tips on system setup improvements would also be appreciated. Thanks in advance.

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)

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

20190821_143603.jpg. Reset display multiple times because first it was showing a constant 2.8A+/- draw with no load. Then finally reset again and load went to 0A but stayed their regardless of load. Voltage registers. Next reset, updated Batt capacity and then got prompts as in title except where there is a "L" it was really an upside down F. See pic. Hit down again and get next pic.20190821_151858.jpg , and next is 20190821_152751.jpg. Can not reset. Disconnected cable and reconnect, no change. App is showing Voltage but no current usage. Appears apparent display is bad but want to check before returning.

First time in 4 years, my system switched itself off because of a temperature alarm. Problem is, I don't know where it came from. I have a Quattro 48/8000 and a BMV-700 (no temp stuff). The batteries have a temp sensor that goes to the inverter, but not to the ccgx. Was it the inverter telling the ccgx about hot batteries?

I have a RV with six 200ah batteries with two Outback inverters. I want to install a BMV monitor. Should the shunt go between one or both inverters and the battery connection bar?
