Where is the detailed excel Modbus-TCP register list?

The GX Modbus-TCP Manual (https://www.victronenergy.com/live/ccgx:modbustcp_faq) keeps talking about an excel spread sheet, but I can't find it. The above manual also has a link for white papers that would include the spread sheet (https://www.victronenergy.com/support-and-downloads/technical-information), but it's not there either.

The GX Modbus-TCP Manual includes the following example: "The Modbus-TCP reply will contain 2302. Divide it by 10, as specified in cell E3, and then you have the voltage: 230.2 Volts AC."

Does anyone know where I can find this excel spread sheet? TIA...

Question about the CAN IDs of the Venus GX (VGX) messages

Hello, I am using a Venus GX to communicate with an MPPT. I have connected a PCAN transceiver to the CAN 2 port of the VGX (not the VE.Can port) and I receive frames with the following CAN IDs:

0x305

0x307

0x18EAE1E1

0x18EAFFE1

0x18EEFFE1

0x19F014E1

0x1CEFE1E1

0x1CEFFFE1

I would like to know which information is within each CAN frame so a PLC can use it for analysis. Can anybody please help me to find any document which explains the information sent by this port? In the Victron's documentation I've found only the PGNs but this is not useful as I want to use the information sent by the raw CAN bus.

Lynx Shunt VE.Can specs and setup

Hi,

I am trying to find a datasheet of the Lynx Shunt VE.Can but am not able to.

More specifically I would like to know the resolution and accuracy of the current measurement.

I intend to use this together with some own developed components and interface through CAN, but will I need a CCGX, VGX to set up the Lynx shunt? Or is it possible to set it up through the CAN interface?

250 Kbits/s battery on Multiplus II-GX ?

Hello!

We are installing lithium batteries with their own BMS working at 250 kbits/s using EasySolar-II GX and Multiplus-II GX units. It seems the Multiplus-II GX units do not have the 250 kbit/s baud rate option, as do all the other GX units.

[image]

Is there a way to get the Multiplus-II-GX to work at 250 kbit/s? Changing firmware perhaps?

The batteries have been tested with a Color Control GX and work fine. But it is not working with the Multiplus-II GX.


Any help is appreciated. We have 450 units of those standing by...

Can API be used for discharge / recharge import / export grid?

Hi there,

I live in an area with notoriously bad dirty (low voltage) power issues and as a result have an interesting spike in power price. I am wondering if the API can be used to instruct discharge when price is high and similarly charge from grid when price is low?

I have not been able to deduce these commands from the api docs here: https://docs.victronenergy.com/vrmapi/overview.html#introduction

I have written a program to handle spot price already, I am just trying to figure out the best way to instruct victron.

Color Control showing inverter in "Off" State

We have a small off-grid system that includes a Color Control, BMV, Phoenix Inverter and Solar Charger.

In the system overview screen, the Color Control shows the inverter as "Off", despite showing AC loads. In the "devices" list, the inverter shows up, and we are able to see the details and see that its state is "inverting". (see attached screenshots).


Firmware on all devices is up to date and we have checked the pins on the VE.Direct cable to ensure there is no damage/debris.


The system is still working fine, the only issue is the erroneous state, but obviously we would like the customer to have a fault-free system. What could be the issue here?

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.

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

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?

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,

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
