Communication Cables advice

Hi all,


We have a client looking to install a hybrid solar system with a small battery backup as well as exporting to the grid. The client wants a Victron system and he has his own panels.


72 x 330W solar panels to be wired with 3 x SmartSolar MPPT 250/100-Tr VE.Can chargers

3 x Quattro 48/10000/140-100/100 inverters (1 for each phase)

1 x Color Control GX


Can you please help me with what cabling and communication I would need to order?

I saw some pictures online with VE Direct cables and network cables, but I am not at all experienced with how the Victron systems communication works.


Thank you in advance, and let me know if there is any additional info needed to help.


Regards,

RV

Can not connect to smart dongle via Bluetooth using Samsung a8

I just purchased a new Samsung a8 and am unable to connect to my 75/15 mppt controller and Bluetooth smart dongle. The dongle is not visible in the Victon connect app device list and does not appear when searching for Bluetooth devices


I can still connect using my old Samsung S5 phone and using my partners Samsung a5. I have updated the mppt and phone to the latest firmware but this did not solve the problem. the Samsung a8 connects to all of my other bluetooth devices such as my laptop, bluetooth speaker and other phone.


Any help would be appreciated

Alternator w/ WS500 and Victron Venus or Cerbo

I love the Victron Venus system and would love to upgrade to the Cerbo (if i can every get my hands on one). I'm currently in the process of upgrading our alternator on our yacht. For this we will use a WS500 regulator which has the ability to get data from the victron BMV shunt in order to control voltage and Amperage coming from the alternator.


My question: is there anyway to see only alternator output through a venus or cerbo device? I know that the WS500 has a CAN bus but i would be unsure how these two devices would communicate or if there would be any way to display that information. It would be very helpful to understand what all the charging systems are doing (solar, wind, alternators, etc) on a single screen.

I do believe the answer is, no, there is no way to do this but i figure i would ask before i close the door to the idea.

Get AC output informations via CAN

Hi,
we are developing an aggregator including 3 Multiplus 48/5000. Our controller is able to communicate via the VE.Bus to VE.Can interface. Currently we can control the inverters and read system informations using proprietary message on the NMEA2000 but cannot get informations about the load because I could not find such VREGs. Which I do not really understand because these informations can be read in the case of other devices.

I would like to ask how I determine the output power, current and voltage data of each phase on the VE.Can.

Thanks,

Communication protocol BMV 7xx <-> Venus GX <-> Smartsolar

It seems as if i have a problem articulating my problem as even #victronsupport has given up on me..!!!

I have to alternate my venus GX firmware every morning to 'activate' comms between my venus and Mppt

My setup is as follows : Venus GX - V2.40 or 2.42, depending on what ran the previous day, MultiPlus 24/3000/70-50 v 433, BMV-700 v3.10 and SmartSolar Charger MPPT 150/60 v1.47.

The issue occured when i updated my mppt to latest firmware. I have tried all permutations of settings to no avail

In the morning when the mppt starts it loops on an error as can be seen in the videohttps://community.victronenergy.com/storage/attachments/7299-whatsapp-video-2020-01-16-at-085946.mp4

From the attached graphs it can be seen that there is some misalignment between the components

Communication protocol BMV 7xx <-> Venus GX

Hi all,

Could someone tell me what kind of "regular" communication is between Venus GX and BMV?

Planned system: MPPT+BMV+Phoenix C + Normal battery + Venus GX ( DVCC + SVS)

Why? I would like to use a monitoring of serial line between BMV and Venus GX (RX line from Venus GX point of view) for regulation purposes ... as a robust way ...

And ... I would like to be sure before buying of BMV and Venus GX ...


A) Is it Master (Venus GX) - Slave (BMV) communication (Victron HEX)? What is the request's frame rate?

B) Is it a type of broadcast communication of BMV (Victron simple TXT)? So Venus GX has every 1s updated information?

I know the Blue Solar MPPT will. Some sources states only Blue Solar...

I've an smart solar MPPT 100/15 (Bluetooth version). Does this version has the VE.direct at the 4 pin connector below the fuse?

And if so what is the serial voltage 3.3 or 5V?

Quattro - Battery data available on VE.Bus?

I am not very familiar with the victron communication universe.

Does the VE.Bus interface of a Quattro provide actual battery voltage and current (charing discharging) data? The device should because these data are necessary for control purposes.

And further more, can these data be logged, either directly on a computer (via MK3--) or via ethernet network (ethernet remote2+Router) without a BMV device?

In this case, can settings be done via this 2 connection options on the device (Quattro) or is an additional device ( VE.Dir. Blue. Smart Dongle ) for this purpose necessary?

The application is actual a test set-up in a Lab.

Kindest regards and thanks for the support.

BMV 712 voltage discrepancies

I have a new RV (Fifth Wheel, caravan, etc.) that came with solar prewired and a residential refrigerator on a 1000W inverter with bypass when AC is present.


I want to maximize what I can do with batteries and solar, I was recommended to Victron. I started with a BMV 712 and a Venus GX, which I've been working with off and on for about a month.

I've been struggling with the no-name cheap batteries (2 x 12vdc lead acid deep cycle) wired in parallel that came in the coach. I wanted to have my math correct before I spent any serious money on high end batteries, so I installed two brand name lead acid batteries with a stated 20 hr capacity of 90 amps each. I configured the BMV 712 to 180 Ah capacity. First, was this correct?

I've been running the inverter and fridge until the battery voltage gets to 12.1vdc per the BMV 712, which I would consider about the maximum discharge to prevent damage on this type battery. Second, does this sound correct?

The refrigerator cycles on and off, but draws an hour over hour average of 45 watts. My WiFi connection draws 5 watts, the Victron gear itself all pulls less than 5 watts together, from metering. Altogether about 55-60 watts, which the BMV agrees with.

The runtime is usually 3-4 hours, which by the math seems very light. Like 1/3 or 1/4 what I should see.

Today I've added a BlueSolar MPPT 100/30 Charge Controller (also connected to the Venus via ve.direct), during that install I was checking the battery pair and noticed the voltage didn't agree with the BMV. A good voltmeter on the battery is showing a voltage typically 25 volts or more than the BMV, so I've been watching this during testing.

I installed the BMV with the shunt, cable, and temperature sensor provided. Is there any troubleshooting or calibration to be checked?

Third, what does the "synchronize SOC" function do, when should I perform it?

Thanks,

Marc

easySolar 48-3000 - communication problem between inverter and color control

I finish to update my BYD battery to latest firmware (after waiting for the special USB to CAN cable from them) so I finally plugged everything and was hopping to have it all to work.

We did the installation a few weeks ago with my PV installer, we did set up to date color control and inverter, and he setted up the victron inverter and color control configuration for them to be ready to discuss with BYD. As the battery was on a too old firmware, I had to wait to update them to latest firmware which is now done (BMU and BMS).

So I finally turned everything on. BYD is recognized by the color control, mppt is charging them, but when I turned on the inverter, it constantly disconnect and reconnect from CCGX.

here is a small video showing what's happening.

https://drive.google.com/open?id=10mD7_XbOBWotqNWOROvzGryRPYZCbU0l

https://drive.google.com/open?id=1-8XvPyB4O5LSNJLkdYXvojTK2sXcuJCP

Any idea what could be happening? How I could fix it?

Also, the inverter has a (quite) loud electrical noise. Is that normal?

Thanks,

Thomas.

Is a GX device required with a Multiplus II + Pylontech US2000 + MK3?

Hi,

I see many discussions using Gx or Venus. Are these guys a "must have" to be able to run Multi II with US2000 batteries ? I only have the MK3, I was told this is enough.

My equipment:

-Multi II version 5010

-A set of 3 US2000 batteries

-18 PV x300Wp, so 5400Wp on the roof including APSSystems YC600 micro inverters

-Multi II AC in : Grid connected wtih the loads

-Multi II ACout1 : PV panels including the micro inverters (so out in 220C ac)

-Multi II ACout2 : empty

Using the VE config and setting up the ESS assistant, the Multi II has initially started in Inverter mode then after 1 min delay in "Mains On", while the sun was down and batteries fully loaded.

So I guess it started to use the batteries to feed the power but as there was no com, it stops.

Can you please confirm my assumptions ? or explain the reasons why I can not today feed the loads from the energy stored in the batteries?

Any workaround ?

Thank you

Fronius Galvo 2.5-1 and Multi 5.0 problems with zero feed in and frequency shift

Hello I have a multiplus 5.0/Venus/Fronius Galvo Grid-connected solar backup system. It Is connected to the local grid and must not feed power back to the grid.

I have set up both systems as described in literature (modbus, ip settings, etc) and added the self consumption hub assistant. The fronius appears in the venus menu and everything seems fine at first.

however, sometimes the fronius is temporarily pushing power onto the grid (up to 1000W for up to 10 seconds) and then resetting itself. This happens when the daytime loads are small and the battery backup is 100%. The fronius will turn on, push power to grid and reset again and again. This also seems to be overcharging the batteries. The whole control system seems very sluggish.

I dont understand why the fronius seems slow to respond to frequency shifting. I feel like I am not using the right assistant for this application. I have read everything about fronius and victron on this website a bunch but just cant get the system to respond right in all situations.

I want to understand better the control mechanism. It seems that while the grid is available the victron multi and venus should be controlling the fronius via modbus, and when the local grid goes down it should switch to frequency control. Am I right? Why cant the venus just control via modbus the whole time? Which assistant would this use?

Alternatively, can I just use a fronius smart meter and separate the two systems? Anyone have experience with this?


Thanks for the any help.

Mqtt or ModbusTCP

HI everyone!

I am about to implement an opportunity load into a Victron ecosystem.

I already have the code to define the amount of power to be derived to the water heater, but I am not sure of which protocol to use, ModbusTCP or MQTT.

I can use both ( as the project is based on a RPi), but I am not sure which of them I should use, as it seems both adequate to my needs of reading variables from the CCGX.

Could you guide me? I have already read the “Data communication with Victron Energy products”, but I found no guidance apart the internet related or not.

FYI: It is for an offgrid system, without WiFi and the connections will be made via an Ethernet cable.

Thanks for your help!

Bidirectional converters controllability

We are currently working on research of PV-based microgrids energy management algorithms. Our facilities include a microgrid with PV panels, PV, grid, wind and and load emulators, batteries (mostly lead-acid) as well as two bidirectional converters with poor user-based external controllability.


We had a look on Victron products to evaluate the possibility to purchase one bidirectional converter depending on their external controllability. In the following we include the grid architecture we are working on as well as a short list of the variables we want to measure/control.

The AC microgrid is composed by two groups of PV generators, the connection to the Utility Grid, an Energy Storage System (composed of a Bidirectional Converter and a Battery Bank) and two types of load demands (Critical and Non-Critical: CL and NCL). PV field 1 with the Utility Grid and the Non-critical loads are connected to the AC input of the Bidirectional Converter and the PV field 2 with the Critical loads are connected to the Bidirectional Converter AC output.

[image]

An external Energy Management System should be able to read and write registers in the Bidirectional converter.

WRITE:

. Power exchange between the Bidirectional converter and the Utility Grid through the AC in port (PBC_ACin)

. Battery Bank absorption time

. Change/discharge or Charge ONLY mode

READ:

. Battery SOC

. Absorption charge flag

All these settings should be modified using a suitable communication protocol via the bidirectional inverter serial port facility.

Is there any Victron bidirectional converter fitting these requirements?
