Hallo Community,

ich möchte den Gesamt-Solarertrag (von meinen 8 MPPTs eines Fremdherstellers) über einen Victron-Shunt messen und ins VRM einbinden. Wie bekomme ich die Kachel rechts unten angezeigt, die normalerweise "PV-Charger" oder "PV-Power" zeigt?

Geht das? Wenn ja, wie?

Vielen Dank im Voraus.

A new beta came out today that includes smartshunt 2.33. It failed during the upgrade. I now cannot connect. I get the message to install the firmware. Tried the officially released version and it fails also. the smartshunt is connected to my color control and appears to be reporting fine. I just can’t connect to it via Bluetooth without getting the message to upgrade the firmware.

I have the controller set at the default 2 position on the dial. The first time I set it up, it got up to 14.4v and went to absorption, then to float. My battery was fully charged. The last two days (everything is new) my battery seems to get “stuck” at around 12.7 volts. I have 200 watts of solar. My battery is back up to 12.6 by noon, but it’s never getting higher Despite it being sunny. All afternoon I see anywhere from 70- 100 watts and 5-6 amps from my panels, but my battery voltage is refusing to rise.

FWIW, the battery and charger are in the same space and are the same temperature. Connections look tight. Things worked on my first charging run also, but not now. It was also in full Sun and got that day too. I’m stumped. Any ideas?

If I look to my statistics in VRM on 30 days there is a big difference between how many power that comes from or go’s to the battery. In my opinion this difference can only be as large as my battery size.

setup: multiplus II go 48/5000 , 6 x Pylontech 2000 battery and a mppt 450/100

Is this combination of components possible to utilize for the desired outcome of a 33v charge?

I've currently got the 12/24v buck boost converter in use but it can only charge my batteries to 30v. (my batteries are 28-33v operational)

I want to take that 30v and boost it to 33v and it seems the only way would be to use the Orion converter then send that into an MPPT.

Is this possible?

Thanks!

I want to make sure I've configured my MultiPlus' correctly. So far when I've used more than one 'Switch condition' all conditions were natually met so I still don't know if selecting multiple conditions are 'AND' values (all must be met), and not 'OR' (any combination).

I was able to verify the 'Extra drive options' are OR values by selecting 'in case of general system failure' and the assistant worked despite being selected. I've created quite a few programable relays to ensure they're evaluated as 'OR' values.

I suppose I can add another programmable relay with mutually exclusive switch conditions. I'd rather know from the source how they are supposed to behave rather than assume and potentially get tripped up on a new firmware release.

Hi all,

My Multiplus 1600 has been working faultlessly for the last 4 and half years, but after putting it on yesterday, it cut out and the alarm led lit solid. Turned it off and on and after a couple of mins did the same thing. No flashing of error code, just straight to alarm on. Tried charging through shoreline connection and that worked fine. Put it to on after an hour of charging and within 20 mins it cuts out again. The manual states error codes for a flashing alarm led, but mine just goes straight to solid on. The voltage at the dc input terminals was 12.6v and I removed both ac input and output connections and it still cuts out. Any help would be greatly appreciated.

Guys, there have been several request now cause there are numerous applications, where a user wants to switch devices based on the SoC, WITHOUT changing the discharge floor.

In my application, I want to use the BMV-700 relay to switch a large power relay to reverse IN/OUT of my Orion, to charge the starter battery as soon as the AUX battery SoC is above 95%. But in regards to the time-to-go, I want to leave the discharge floor at 25% (75% DoD).

I urge you to take these request into account when determining the scope of the next firmware update. Please !!

After upgrading the firmware of my Venus GX to version 2.72 I am having issues with it not continuously publishing to the mqtt broker.
When I connect a client to the broker in the GX I receive the subscribed messages for about a minute after which an empty message is received and no more messages are received until about 1 minute or 2 later. This just keeps on repeating.
I suspect there is a timeout issue or it somehow does not get the keep-alive messages.

I was unable to find a change-log for 2.70 to 2.72.
I would also rather not roll back but I also cant seem to find a way to even roll back the firmware.

EDIT:
After creating a profesional account I am able to access the changelog. Though that did not really explain why mqtt is misbehaving in 2.72.
It did however point out how to roll back so I rolled back to 2.66 which resolved the mqtt issues.

However that may cause me to be unable to configure my EM24 ethernet as that was not yet added in 2.66.

It seems that my Blue Solar 75/10 is slow ramping up power when in float and the battery voltage suddenly drops.

Is there a handle to make it compensate quicker? Re-bulk ia way too slow with a fixed delay of 1 minute.

I've built some solar power systems in the past around lead-acid batteries, and they're generally fairly straightforward because of the ease of charging lead-acid. For example, I could feed a lead-acid pack with both a solar charge controller and a wind charge controller wired in parallel.

But now I want to build something with more options based around lithium battery chemistry. I feel like this has been done over and over, but I'm having a hard time finding an overview.

I want a battery-powered system of DC and AC loads (this part is easy enough), with solar, wind, and grid power inputs. The grid power has to be flexible, 120/240 V, 50/60 Hz. And it needs grid isolation (this is a marine application). And the batteries are lithium (probably LiFePO4), with all their attendant charging requirements (I know a lot of large Li batteries have some built-in BMS capability). And note that the DC load can be quite large at times (peaks of 20 - 40 kW). I don't think Victron makes anything that operates over 48 V, but 72V or 96V for the pack voltage would be a nice perk.

Are there any resources describing such a system? Thanks!

Hey!

I got myself a SmartSolar MPPT 150/45 - TR with the Display option. I switched from my 100/20 to the 150/45 because the smaller one was on its limit.

The problem that I encountering now: The new MPPT doesn't go into float.

It's connected via VE. Smart Network to a SmartBMV 712 and a SmartBatterySense. On the app, the MPPT says it's using external voltage and external Battery current sense from the BMV and Battery Temperature from Battery Sense.

Its also connected to a Raspberry Pi running VenusOS.

Right now, the MPPT is set to a maximum absorption time of 6h and an Absorption Tail Current of 4A. The MPPT as I'm writing this is charging the Battery with 3.1A (MPPT Reading) where 2A go to Battery (BMV Reading)

From my understanding, the MPPT should go into Float if the Absportion time is at max 6h or the Battery Current goes under 4A for one Minute.

Today it started charging with 11.8V and is in absorption for 4 hours.

Typical days are, charging bulk over the day, going to Absorption, Battery Current falls under 4A, and MPPT still in absorption. Then, when I come home and using the energy, it goes back to bulk if the sun is going down. Or if I'm not using Power, the MPPT going straight from Absortion to off.

2 Days ago it once was in float for 20 Minutes then the Sun gone down.

I think it is not good for the battery if it's continuing this. Does someone know an answer to this?

CANvu GX is suggested to be used for harsh environments and is the only GX device that supports an extended temperature range up to 70 degrees.
Therefore I want to use this GX device.

However, there is no wall mount for CANvu GX and also no mounting for the IO extension and wiring kit. How are other users installing this GX device? In what type of box are other users installing this GX device?

Thank you.

My camper has a Lithium battery and a none Victron BMS. I’d like to use relay 1 on a Cerbo GX (which I have in my system) configured to start/stop generator using SOC <98% start >99% stop so the Cyrix can switch on/off the alternator charge to the leisure battery. My question is how do I wire the cerbo GX relay and Cyrix Li-ct.

Lightening blew out my system. So we replaced 2x 5kva Multiplusses, the Venus GX and the Freedom Won BMS that got blown. The RS485 usb connector to the ET112 was also replaced as dead. The ET112 seemed to be alive but the Venus refused to detect it. I then replaced the ET112 with a new unit. Sadly still no detection. Is there perhaps a trick I am missing? On the VRM Portal I deleted the old ET112 Device as it was last seen on the day of the lightening strike. Was that perhaps a mistake? Any help will be appreciated.

I have a new MultiPlus-II GX with a Hubble AM-2 5.5kW battery installed for 3 weeks now.
The output of the unit feeds a 3kVA APC UPS loaded at about 1kW.

Every time the battery charging current goes below two(2) amps after the battery was charged or top-up, the output voltage and current drop "Spike" - 97Vac and 0.9A - 230Vac and 3.7A is the normal running values, so low that MY APC UPS has to go onto battery to keep my servers running.
See attached image.

Any idea where we can start to look why the output dips?

Hi Community new here am having a problem with my new syatem i put shore power on, last night it shut down when i put 2 heaters on the inverter was sitting at 4400w with shore power for about 7min then shut the shore power of saying overload and loss of grid power i have the quattro 24/8000 after that i reset the notifications rebooted the gx and swithed inverter off then back on still not working then i changed ac 2 in as shore power and iton ac 2 in either is there aomething else i need to reset i am on our trip and in toowomba the inverter has not missed a beat been great every stop we have been at,i can here the imverter click when i put the shore power in again also so its registering that the shore powers being connected and then throws up the notification in picture attached,oh also charge only does not work either

Hello to all,

I had the following “On grid” configuration:

• 1 Fronius Symo 10.0.3
• 1 Multiplus 2 GX - 5000/48 “hooked” on phase 1
• 1 three phases Smartmeter
• 1 Smartshunt 500/50ma
• 220 Ah Li Ion batteries
• 18 solar panels 370 wh each in two strings – 10 on one string and 8 o the other. (intention is to install another 10 panels)

As this year the grid electricity starts dropping every week (they are replacing the old network) I decided to get an MPPT 450/100 to make it work in parallel (Off-grid during the electricity outages) therefore I disconnect the 8 panels string from Fronius and I connected it to the MPPT.

MPPT and Smartshunt are connected to the MP2 via VE.Direct.

The main issues are as you can see in the prinscreen of VRM or console:

• When there is a high load, the system is getting the power from the batteries and the MPPT goes to 0
• Is throttling the Fronius inverted to 50-60% of normal production and is getting the difference from grid.

[image]

The funny part is that if I am connecting to the MPPT via Bluetooth or in the console and I am looking for the production of MPPT is shows about the right amount but somehow this is not showed in the VRM neither console Pages. I have no idea which ones are the right values.

Hi everyone,

I can't find a lot of detailed information on the Smart BMS CL 12/100 and was hoping for some insight on how I've applied it to my system. The main reason I wanted to use it was it provides more amperage than the Orion.

(I have yet to add wire size, fuses and breakers to my diagram)

Any help, insight or suggestions would be greatly appreciated.

(Van is a MB Sprinter, 2 x 200ah Lithium Victron Batteries, BMS is connect directly to start battery)

Thanks!

I am planning to upgrade the 12v house bank in my boat to lithium. In the process I need a new 230v charger, with 3 outputs to charge this new lithium bank, plus agm starter batteries, plus windlass/thruster battery.

looking for high capacity as well as keeping it on more or less constantly to maintain and keep all batteries topped up and in good shape.

the Skylla 12/70-3 was recommended to me but then I was warned that it would not cope with batteries of a different type.

Also, I already have the Argofet 200-3 mounted, and it works great. But again, someone said it would not work with one battery bank being lithium. As that bank is so power hungry the theory is that no charging current from the engine will reach the two other banks until the lithium bank is full.

Is it true? Or will it work? This lithium upgrade is turning into a headache before it started.

Hello everyone, I am almost confuse about to monitoring 3 MPPT Smartolar charge controllers that we are going to connect to the Cerbo GX. Because the solar installation is more than 20 years old, "unfortunately" we have 3 string of solar panels connected with 3 battery banks and after by schottky diodes to the load (MM.WW. system), but we can´t optimize the banks because the space of each one is limited to joint them on one battery bank. for that reason we should monitor each MPPT Charge controller separately. Is it possible to monitor each MPPT (PV power, BAT power and load consume) or each MPPT should be connected to a GX device?.

Thanks for your support.

Hi. I am the lucky new owner of a Multiplus-II 24/3000-70/32. Just installed it and started using it. I have two questions, the first purely informative and the second more practical.

1. It's humming loudly (relatively). The less load on the inverter the louder. As I go long days with low loads (50-250W) it seems that it will be humming a lot under my ownership. I'm just thinking - sound means vibration and vibration means wear. How will all the solder joints, capacitors and everything hold up with that constant vibration. Maybe I am just paranoid but no other inverter I have used before have had that kind of hum constantly. Can someone put my mind to ease about this and explain if it is just the way they are designed and that it is ok, or otherwise?

2. I have PowerAssist in this inverter which is supposed to combine the inverter ac current with incoming current from the grid or genset if needed upon high enough demand. I have a 900W 24V sine wave inverter from another brand laying around. I wonder if, in the situation I needed it, I can connect that other inverter to the battery pack and feed it into the multiplus to get 2400+900=3300W? Is that a dumb idea or a reasonable thing to do in a pinch?

Best Regards,

Hi

I have an Phoenix 12/1200 in my motorhome, and it makes a buzzing sound when it`s turned on. And when I put a load on it, when charging our e-bikes with 160w AC, the buzzing gets really high.

I did return it to the seller in Germany, But they said it is like that with Victron inverters… so they sent it back to me and they also send me some rubber ”feets” to put between the inverter and the wall so The sound dont get amplified from the wall

Is this normal?

is there anyone else with similar problem?

Until yesterday all was working fine. No error lights on the Quattro. Since today of we want to charge by generator, the Quattro stops charging. Quattro is first switched to charging mode from gender and then switched off again (we can hear the clicks). Generator is working fine, that is tested. All other functions working fine (solar comes in, Quattro is inverting). Both BMV and Venus work well and show all other functions. Does somebody have an idea what we can do?

Hello,

On a new Quattro 10000 after firmware upgrade to the last version, with VictronConfigure3, in gris tab, "France: VDE0126-1" is not available.

Why ? Is it dependant of firmware version ?

Thank you for your help.

the fan of my multiplus II is blocked at night during its shutdown and in the morning I have to restart it by hand.

I ordered a new fan, in the meantime can we force the fan to run permanently

Hello everyone

I need some information:

my system: multiplus II GX 3000VA 48

: MPPT 150-60

:COUNTER

ESS, DVCC charging current limit 60A

lifepo4 200Ah 16x 3.2v

voltage absorption 56v

Float voltage 54v

with a -1000w network, 1600W MPPT power

the charging current peaks at 40A?

which parameter is blocking?

Hello ,

I was able to have the SMA party AC recognized

but here is another example of limitation

The output power of the multiplus is limited to 1000w why?

the battery should provide the missing power

How to control the operation of the cooling fans of the multiplus

I find the multiplus II very hot and I don't hear the noise of the fans running

Good evening, I opened the lid of multiplus II GX, the fan was blocked, which explains the current limitation in charge and discharge to limit the temperature of the devices

Hello everybody,

I am a bit of a beginner in all of this electric wiring, so forgive me if I dont use the right terms etc.

I recentlly got myself a 90Ah Victron Life4po Battery, the victron BMS 12/200, bmv 712 and a 100 watt solar panel with mppt 75/15 module.

I did all the wiring as shown in the graphic. The setup is used in an old mercedes 307D van and I wanted to use it seperately from the starter battery and alternator. I was a bit worried that my alternator could be to weak (it only delivers 55A) to permantly charge the lithium battery and I am only using the van in summer when sunlight is not an issue for charging.

So I connected the mppt minus to the Load Minus of the BMS and the mppt plus cable to the plus of the battery. The bms charge led is green with this setting and the bmv shows some Ah which have been generated by the solar system.

So far so good, but once I connect electrical consumers there seems to be an issue. For instance I connected a 12V USB charging station, the plus cable to the plus of the battery and minus to the LB Load minus. Now, my phone will charge but the current seems to switch on and of all the time. The "Output on LED" of the BMS is not green ( dont know if thats the issue) and in the bmv it is not shown that current is drawn from the battery.

As a Newbie to electrics I am unsure what else I could check or how to trace the error. I also tried to connect a compressor fridge likewise. The display will turn on but the compressor doesn t start.

I would really apreciate any hint on what to do in order to find a solution.

Hello together,

I try it again...

I have an installation with Cerbo GX and BMV-712 Smart.

I used a VE direct to VE direct cable to connect the BMV-712 Smart to the Cerbo GX.

Unfortunately the BMV-712 Smart is not visible in the Cerbo GX device list.

I didn´t find anything to fix this.

I hope there is anybody who can help.

Thanks in advance

Jens

Hope someone can help,

This particular site doesn't show the Venus correctly in the device list Gateway section, installation also isn't visible on Victron Connect.

Site is accessible via Remote Console, Venus firmware is V2.72 and the Multi is on the latest FW.

Any ideas?
