Hi All,

I have two MPPT 250/100s in parallel.

I have connected them into the wireless network with the BMV712, which is connected to the CCGX. I have also connected them to the CCGX via the bus to USB converters and then to the CCGX and neither of these systems worked.

The chargers do not play well together as one takes the lead say 70amps out and the other just idles at 15amps.

I also cannot "see" these chargers in the VRM portal or the daily PV yeild which I would very much like to see.

The firmware in all the items was updated last Sunday to the latest.

The inverters I am using are two 48/5000 Pheonix in parallel master/slave configuration.

The BMV 712 also goes into charge disconnect, which I would have thought would be part of the wireless/USB network function

Probably enough questions for now,

Cheers,

Dave

Hi all,

We are employing the SmartSolar MPPT 75/15 in a number of remotely located instrument cabinets that will eventually be inaccessible to people. To remotely monitor the SmartSolar device, we are utilizing a Serial to Ethernet bridge. This device also allows us to also perform any mandatory firmware updates remotely, but with a caveat.

In order for us to be able to take advantage of the SmartSolar’s load current sensing, our load (‘Ethernet Devices’) needs to be connected to the LOAD output. However, during a firmware update, the LOAD output switches off at the 4% mark, thereby causing the firmware update to stop indefinitely. D1 solves this issue by sourcing power directly from the battery (Batt) when the LOAD output switches off (during a firmware update). The side effect of connecting the Batt terminal to the LOAD via D1 is that the LOAD output never comes back on, despite VictronConnect stating that the LOAD is ON. Instead current continues to flow through D1, therefore current sensing on the LOAD terminal never takes place. Only by utilizing D2 does the load current flow through the LOAD terminal and reported in VictronConnect.

Our question: Before we invest time in building a low-power-loss device (FET in place of D2) to circumvent this issue, is Victron able to provide a firmware update that ensures that either the SmartSolar LOAD output always stays on during a firmware update, or at least a firmware update that would allows us to omit D2? And failing a response here, how can we contact Victron directly with this request?

Thanks in advance,

Michael

Hi,

I was hoping i could see how others have implemented the Ziehl anti islanding units in their installations.
I find the schematics in the manual a little overwhelming and would like to see examples in victron installations if possible.

Are you using one or two contactors?

Kind Regards

After the recent firmware update, I can see battery monitor listed in the app, but won't connect... It gets to 20% connection and just hangs they're forever. The mppt connects no problem.

I tried unpairing the Bluetooth and repairing, which didn't help. I tried unplugging the cable from the monitor and replugging it in, but that didn't help either. Any suggestions?

Did a job w/ Multiplus2 and BYD.Updated the firmware to 466 with Victron Connect.The Multi went nuts,running the fan,drawing rapidly fluctuating amps from the battery,wildly importing/exporting from the mains,etc.

Changed firmware on the BYD's to V4.4.12 and V2.V4.25 on the BMU.No luck.Reloaded 466 again,still no luck.

In the end had to go to Victron Professional,get firmware 459,use VE Flash to load it and problem solved.ESS assistant is being used and BYD settings as advised.

Anyone had problems with 466?

I’m seeing something very interesting.

When I disconnect my multiplus from my 12v battery, I see 13.2 volts across the BAT - and +.

The multiplus BAT + is connected to a bus bar that my dc loads are connected to as well. When I flip the breaker for my dc loads, the voltage drops to 4.8 volts. No dc loads are running except for a few control panel LEDS which can’t be more than 50 mA.

Is it possible a capacitor is tied to the positive terminal of my multiplus and it’s getting the voltage from that?

Will the ve.configure work ok with MultiPlus Compact Inverter 24/2000/50-50 120V

I have an issue with SmartSolar 150/85 showing pv voltage equal(-0.5v difference) to battery bank voltage even when no pv input is connected.

As this is a new unit purchased for testing purposes, does anyone have an idea what might be causing this?

The unit can still charge correctly, but after removing input source, the pv voltage shows a higher voltage than battery bank until Remote jumper is removed. Needs to be reset otherwise it stays in Bulk mode even though no pv is connected.

It obviously has been damaged during testing, just not sure what to check for repairing.

Also finding it difficult to remove blue cover :)

Any help would be greatly appreciated.

Victron 150/35 with BT dongle, LiOn Batts at 36 volts, 7X100 watts panels, 12 gauge 25ft cable to the charge controller, when I switch the charge controller to 48 volts, the voltage goes up but the Amperage goes down. If I switch back to 36 volts, the voltage goes down and Amps go up. I understand that is negative resistance, the backup system setup remain the same no other changes, except that when the batteries have been charged at 36 volts to full, I switch to the GTI and divert the charge controller output to the house to use excess power. the GTI can accept 20-60 volts input it can generate up 3.5Kwh on a good day which is half of my daily power consumption year around except during Summer months where my consumption goes way high because of the AC unit.

Hi, I’ve got a SmartSolar controller. I’ve had it setup for a month now and no problems but now Bluetooth light does not illuminate on the controller anymore. My friend has exact same controller and we can both connect to his controller but not mine.
I have an iPhone and he has a Samsung. It must be something wrong with the controller as the blue Bluetooth light does come on.

Should also add that the controller is working and charging my batteries. Fuse is also fine.

Thanks for any help.

When I put the shunt the rj12 port is down side and the utp cable dont look clean, I mean it needs to make a loop that I dont like. If I change the shunt to oposite side is the battery cable 2/0 that has a big and ugly loop. So if I change the little board on the shunt I can run the cables better and make a clean installation.

Also I need only one feet of utp cable, in the box come 30 fts of cable. Can I cut it and just put a new rj12 connector?

thank you so much for help

Hi! I have a question about charging a AGM car battery. The manual says that the "normal" mode (14.4 volts)should be used. As far as I know AGM car batteries needs 14.7 volts, that would be the "high" mode?

Good morning, hope everyone is well?

I am using a CCGX (with firmware version 2.33) to try and connect to two Dyness B4850 lithium batteries. According to the battery supplier, Victron and Dyness are compatible but I cannot seem to get the CAN communication between the two up and running. As a result the batteries are continuously going into protection mode because charge from the 3kW Multiplus and the BlueSolar 150/35 is not regulated by the CCGX.

Are the two products compatible and if so, what can I do to get them working together?

Thank you in advance.

I have 2 100/30 Smartsolar MPPTs integrated with a Quattro 5000 into an ESS, running on 24V lithium batteries.

Everything had been working fine for weeks, but sometime this afternoon the system suddenly and inexplicably went into passthru. At the same time, the solar input dropped to zero.

There seems to be no way to take it out of that mode.

I tried disabling and reenabling the MPPT chargers

Restarting the CCGX

Changing the grid set point, and ESS mode, and Min SOC percentage

Updating the firmware on the MPPTs to the latest

All to no avail.

Ive already gone through the ESS manual (and the appropriate section in it often mentioned in this situation). But none of the presented situations seem to apply here. I do not have a grid tied inverter, do not feed power back to the grid, have the batteries at around 75% SOC and ESS is optimized without battery life. The batteries are managed by their own BMS and are perfectly able to take and deliver a charge.

If I kill the breaker for shore power the system will invert but if I reapply power, it quickly flows from discharging back to passthru.

Any help on this issue is greatly appreciated.

Thanks

I'm upgrading my boat house bank and inverters to supply new heavy loads like induction cooktop, demand water heaters, and A/C. I'm trying to figure out what quattro setup will minimize the quiescent drain. The system is 24v 1300ah LiFePO battery bank, and either two Quattro 24/8000, or 2-3 Quattro 24/5000. I've heard the quiescent drain is rather high on Quattro, especially the 8k version. I would like to avoid high parasitic drains on the system.

If running two Quattro in parallel is the full active Iq going to be drawn by both? or does one step in when the other is heavily loaded?

If I run one Quattro into the second Quattro with the second configured for PowerAssist will that reduce the Iq on the second quattro? What is the Iq of the Quattro when in Powerassist mode, but not supplying current?

Are there any issues with daisy chaining Quattros like this?

Any suggestions on Quattro selection and/or topologies to address my needs would be appreciated.

Greetings

I am new to Victron. I have installed the EasySolar in an off grid setup with 9.6KWh batteries (4 x 12V 200AH LiFePO4 - Non Victron - Built in BMS) and upgraded all the firmware.

I have 5 panels in series delivering just under 110V when disconnected and about 10A in short circuit.

When I connect the panels to the unit it doesn't charge the batteries. It issues error #38 input shutdown due to battery over-voltage. I then have to go through the process of resetting the unit.

Any help with this would be appreciated.

Cheers,

Mahmm.

Having read the Venus GX (and CCGX) Manuals I am somewhat unclear about what is eventually displayed on the glass bridge w/r/t DC activity. I have a Quattro maintaining a 48v bank (electric motor) and a 48/12 DCDC maintaining a 12v bank (house/windlass). I have a BMV-702 that I planned to shunt on the 12v bank. I believe I can connect both the Quattro and the BMV-702 to the Venus GX. I’m not sure if any of the Victron 48/12 DCDC converters can be connected (if so, perhaps this is better solution than the BMV-702). In any case, whether it’s Quattro and BMS on the Venus GX, or Quattro and DCDC Convertor on the Venus GX, it appears from the manual I must pick one DC source to display? Does this mean the glass bridge can only show one? In other words, I can see what‘s going on with the 48v bank, or the 12v bank? If I cannot see both DC banks simultaneously (via Quattro and BMV-702, or Quattro and DCDC, can I toggle between them on the glass bridge (in similar way that I can toggle Battery 1 / Battery 2 on the BMV display iitself? Thanks! Peter

I was wondering if I could post the wiring diagram I have made in preparation for an installation in a 2018 Mercedes Sprinter Motorhome conversion with nearly all Victron equipment. I wanted to check before ordering everything that I hadn't gone overboard nor missed anything out and would really appreciate passing it by someone/s here if anybdy had any time/interest?

Thanks, Ben

Hello, I have a Multiplus 2000/12 connected to a single Battle Born Lithium battery. Every now and then when I turn the Multiplus on (using on/off switch, not the hard switch on the Multiplus) it trips the BMS on the Battle born. Then I have to disconnect the battery and reconnect to reset the BMS. I have no idea what is causing this. This usually starts happening when I turn off the power to the Multiplus without turning off the Multiplus first. Then it starts this vicious cycle of tripping the battery every time I send power to the Multiplus. I have checked all the wires and everything is tight and isolated. It almost seems like something is bad with the Multiplus or Battle Born. Both the Multiplus and Battle born are brand new. I haven't even started using the Inverter yet just the charging.

I did fire up the inverter on a test run and the buzzing was really loud (normal?) and then it too tripped the BMS after 2-3 seconds.

Thanks for any help. I live in Colorado and I can't find anyone I can pay to come and help figure it out. It seems even the distributors of Victron don't know how to service them. Also, I have had Victron pros in this community validate my schematics, but happy to post again.

Hi,

I bought a Victron Blue Smart IP67 12/25. Will be using it to monitor and charge a lead acid battery.

Is it correct that when only the battery is connected (and not 230ac) you can't connect with bluetooth?

Thanks!

Dear community,

I'm trying to set up a Venus GX with a GX GSM. The GSM doesn't show up on the menu of the remote control so I figured I'd update the firmware first (currently 2.18).

The problem is the following: The Venus GX keeps disconnecting from the remote console and wifi after some seconds. It disconnects from the remote control (on built-in WiFi, lan and vrm alike) and also from the hotspot I'm trying to use to do an online update. So I'm able to do some settings if I'm quick but it won't stay connected long enough to do an update.

What could cause this behavior? I have tried two different units of Venus GX and both exhibit the same problem so I don't really believe in a defective device. Also the gx is able to send data to vrm when connected to a hotspot, so it's essentially functional.

Any ideas?

Best regards, Anna

I'd like to remotely switch on and off the inverter ("on" on the front panel) which runs to a conviniently situated switch but also swiches more things at the same time. When I need charging I need to keep the inverter off in case of malfunction or generator running out of fuel. Therefor I want to have the front switch sitting on charger only.

As it is wired now I switch over to another inverter since the multi can only do either or but is then remotly switched off so "charger only" is disabled too.

I then need to take out the two wires and put in a bridge. Is the third port for the charger only side and I can put a bridge there?

How do I need to wire it?

Cheers guys

Hi Folks,

Question:

The Autotransformer inside Inverter is that a fullisolation output?

because Connection to shore power with RCD 30 mA and bridge

between NULL and NULL (blue) ouside Inverter

both ways are then a full european Network TN-S

Possible ? or not ?

I dont like the IT Network (insulation checking is necessary !)

Thanks a lot best regards Questus

Hello,

I'm planning an off-grid installation with four solar panels, a SmartSolar MPPT 100/20 (48V) and a MultiPlus II 48/3000/35-32.

I'm wondering how I could monitor my system and I see (at least) two options:

1) Raspberry py

In this case I'd need to get:

• UTP cable + MK3-USB interface to connect MP II to the Raspy
• VE.direct cable + VE.direct to USB interface to connect the MPPT to the Raspy

Is that right? Or can I connect the MPPT directly to the MP II? In the latter case I don't need to buy VE.direct to USB interface

2) MultiPlus-II GX 48/3000/35-32

In this case I'd need to get only:

• VE.direct cable from MPPT to MP II GX.

Is that right? As MP II GX has only one VE.direct port, is there any other way to connect MPPTs to it, in case I will expand my system?

Do I really need MK3-USB interface with MP II GX? What's the purpose of USB port??

Which option do you suggest?

Sorry for the large amount of questions and thanks in advance for helping me to have clear ideas :-)

I have an issue with the AC output on an off grid system - 10 Kva quattro / 2 x 13.8 Kwh BYD / 6 Kwp DC coupled PV with a Stephill geni (approx 12 Kva). There seems to be a "wobble" in the frequency of the AC out when the transfere switch operates. This seems to be most prevalent on generator shut-down and causes issues with electronic equipment on the AC side of the installation. I have tried the usual "tweeks", any advice as to how I can clean up the output to prevent this ..

Hi Sir, I have a BIPV Solar system with different technologies. I am using 4 Nos. of 150/70 Charge Controller and want to connect the system to Victron Lithium HE Batteries (24V 100AH) along with LYNX ION BMS 400. Please, can you advise if the 150/70 Solar Charge Controller is compatible with Victron Lithium HE Batteries?

Another solution is to use Victron AGME Lead Acid batteries in 24V 100AH configuration. But do I still need a BMS for this to ensure my batteries do not get damaged and are protected against overheating? BMV 700 seems to be only for monitoring and is not going to open or close any contactor for Lead Acid Batteries.

Thanks a lot

Hi.

I've a Multiplus 48/5000/70 with firmware 400. When I connect it with a MK2-USB and the latest version of VEConfigure 3, they retrieve all parameters but if I white new parameters to the inverter, the program stops at init of writing and show me an white error.

If I use an old version of VEConfigure (the version that need the password), is no problem to read/write parameters to the inverter.

The problem is the old version of the firmware?

And, other question: for change the Grid country, i will need a password? What is?

Thanks!

Replace Mastervolt Combi with Victron Multiplus to have better monitoring > Can the Multiplus run with the batteries disconnected?

A potential customer has a Vehicle2Grid system. It a living boat with a grid connection and solar panels and a smaller cruiser boat with battery and electric propulsion. Normally the small cruiser boat is next to the living boat and the battery is connected to the big living boat and grid and solar panels and is being used to maximise self-consumption. The system has Mastervolt lithium batteries on the small boat and some switching to connect the batteries to the electric propulsion and a pluggable cable connection to the big boat. On the big boat the battery cable is connected to a Mastervolt Combi battery inverter, which is also connected to the grid connection. On the AC output (micro grid of the big boat) are the solar panels, connected with a Mastervolt AC PV inverter. The Mastervolt Combi is 5000 VA/Watt. There is 4000 Wattpeak of PV panels and a 6000 Watt AC PV inverter. The Lithium batteries are 4 pieces of MLi Ultra 24/5000 (24 volt 180 Ah) in 48 volt configuration.

The system has a dashboard that is base on the Mastervolt monitoring software. But this is not maintained anymore and has all kinds of problems. This is the mean problem that needs to be fixed. It's also not really handy to select another battery usage mode (switch from Max. self consumption to Keeping batteries full, etc.). Also it runs on a laptop, which only purpose is to run this dashboard, which is a waste of power. Etc.

I suggested changing the Mastervolt Combi 5000 VA for a Victron Multiplus 5000 VA, so we could use the CCGX controller. Then we can have a good monitoring system that is being kept up-to-date and under active development. And it will be much easier to change battery usage mode. This can then also be done remotely, something that is not possible now. Also then they can get rid of the dedicated laptop and then will consume much less power with the CCGX. Also it will be easier to interface with all kinds of stuff, now and in the future.

The big question is: Can I use a Victron Multiplus 5000 for this. Because the system needs to run, also when the battery is disconnected, because this is something that normally the Multiplus doesn't like or even can't do??

I am not sure how this works in the current configuration with the Mastervolt Combi, because I was under the impression that this battery inverter also wouldn't like to run without the battery connected.

Or is there some "trick" I can use to keep the Multiplus running, when the battery is disconnected?

Any suggestions and help is welcome. I would really like to make this system (dashboard) working again with Victron equipment, also because this project would open doors to other interesting solar-battery-grid balancing projects that this customer is involved in.

Thanks in advance for any help! :-)

Does anybody know an electro installateur who has experience in setting up an ESS (victron) for PV in Berlin?

My electro guy is a little afraid.

CCGX + multiplus 2 + pylontec 2000

Is any electrician capable of setting this up?
