Hello,

Our previous system setup was the following:

• Color Control GX
• Quattro 48/5000/70
• Pro 2.5-10.0 battery box with 2 Lithium Ion Battery Cells
• BlueSolar charge controller MPPT 150/85

As BYD batteries require using a Ve.Can port of Color Control GX, we were not able to communicate MPPT with our system and charge batteries with solar panels.

We have bought a new Venus GX and have replaced the Color Control GX.

MPPT was connected to the Venus GX using its 2nd Ve.Can port.

MPPT turns on in Bulk mode, batteries are charging but Venus does not detect MPPT, it shows the system inverting (system is currently off-grid) while batteries are actually charging.

How could we solve this problem?

Thanks in advance.

Good day Matthijs.

I still have a problem with CCGX, getting it to communicate with Multiplus.

CCGX bought around 2014/15, but not installed/connected. Now wanting to add to system, running a BMV700.

CCGX does not "boot"?

What to do?

I have the EasySolar 48/3000/35-50 mppt150/70 with 4 12.8V Lithium (LiFePO4) batteries connected in series. All works fine, but the CCGX don't display SOC. I guess this might be firmware related, but I'm new to Victron products. The multiplus inside the EasySolar has firmware version 413, the MPTT runs on v1.39 and the CCGX on 2.23. Should I update the Multiplus? Greatful for any guidance here, thx :)

I have two mppt charge controllers (100|50) who charge a battery. I would like to connect these charge controllers (with each a VE terminal) to the my inverter multiplus compact 24v|2000. This inverter has just one UTP terminal left. How can I both charge controllers connect with the inverter?

3 x multipus 24/3000 in parallel

Issue if I set the input current limit to say 20 amps. and then apply loads of say 18 amps then the input current exceeds this buy the battery charger setting power.

I then have to limit the battery current way down to say 6 amps per unit at 24 volts so that I can stay under the 20 amp current limit. while running other loads

I would have thought that the charging would have been reduced first to zero rather then exceeds the max current limit set when other loads are used.

also if I raise the max charge rate to 70 per inverter then the amps drawn goes way over the 20 amp limit eve with no loads.

have tried this with the DMC and the CCGX and by checking that the changes have been applied correctly to each inverter with ve config and they have been

firmware version 459

any ideas out there, pain in the backside changing the battery current limit setting all the time

The site has 3 multiplus units all on 459 firmware all in parallel

the site works fine using the DCM or the CCGX NOW but connect both and the DMC works fine but the CCGX keeps dropping out and then back on then out again

by this I mean it shows the correct infor then the info drops out and the display says OFF, however the DMC still stays working and so does do the inverters

I have tried new cables and changed them ALL to Cat 6 Cables with plastic plug ends

History

1. first of all I installed the CCGX to the site with the DCM connected and all worked well. this had a 20 mtr cat 5 cable from the inverters to the ccgx then a 1 mtr to the DMC the CCGX on 2.23 FW

2. then I changed the inverters battery cable lengths so they where all identical

3. I then upgraded the firmware from 419 to 459

After the above had been done

The CCGX would not connect AT all and I also could not get a connection with the MK3 but the MK2 would work.

I then ran a temp new victron cat 5 - 10 mtr cable and the CCGX would then work but connect the DCM and the CCGX would go off line, use a 5 mtr cable and all worked fine, but this is way to short and I cant leave it like that on the boat.

I then had the original cable shortened to the Min length I could get about 9 mtrs, and the inverter interconnects also replaced with cat 6 and shortened it min lengths posable.

in the end to even get the CCGX to work on and off on off etc I shortened the ve bus internect cables and this then allowed the CCGX to work abate not to well, I even tried putting it up to the release candidate firmware as well

Now the CCGX works in and out when the DMC is connected but fine on its own.

*******

My suspicions are that the VE bus signal from the inverters has decreased in output power somehow, with the firmware upgrade.

the site is available via VRM if needed its setup as B2 on my site list plus the DMC is not currently connected so the CCGX and the VRM are working fine.

Note the CCGX is using the victron wifi dongle

Any one got any fancy ideas or tips

My MultiPlus II 48/3000 is still on backorder and I am busy preparing the mounting area. What is the measurement of the bracket bolts position to the top or bottom of the unit when mounted? I know the unit itself is 499x268x141mm.

I have a 3600 isolation transformer. Recently one of the jumpers on the AC input started overheating to the point of smoking. This is the jumper between J17 and J20 used for 115 V input. The transformer feeds through a Victron inverter/charger to my AC panel. I have had this setup for several years with no problems but with usually small AC loads, Just installed an air conditioner that draws 10-12 amps running. Ran this setup for a few days at the yard before moving to a marina. Ran fine plugged into 30 amp 115V shore power at the yard and I didn't notice any problems. Moved to the marina also connected to a 30 amp 115V outlet. Noticed two things. One, the air con has trouble starting and the inverter kicks in to boost the shore power when the compressor first tries to start. Then after the air con had run a while I started smelling smoke. Shut down all power and checked all the wiring AC and DC and could find nothing even warm. Restarted everything and smelled smoke again and finally traced it to the isolation transformer. Open the case and found the jumper smoking and very hot. My guess is there's a problem with the shore power at this marina but would welcome any comments or suggestions.

We are to install Trojan Trillium LiPo Batteries on a vessel that will have 8KW Quattro's and a Colour GX system, the Trojan lithium batteries have an inbuilt BMS that can communicate/ report status via CanBus.

Can I connect and display this information on the Colour GX using the VE.Can connection?

Dear friends,

I have experienced a problem with a customer's ESS system. Multiplus and Fronius inverters are connected in parallel to the grid. There is a TOPzS batteries installed. ET112 meter and BMV700 is installed too.

My customer told me he noticed 2 power outages. I think the problem comes from the BMV monitor, but a problem from the grid meter has more sense as I have read in FAQ4 from ESS manual. I attached pictures from the VRM portal:

The previous night of a power outage, I found some error from the BMV monitor:

And this 25th april when I enter in the VRM portal, It showed an error message in a red window, it says something like "a device is trying to send data". I had to restore the token authorization in order to solve the problem But before restoring the token, I noticed this:

I called my Victron Seller in order to request them to write to level3support mail. But I have no news and no technical explanations.

Please, could you help me? If you need more information, please let me know.

Best regards,

Daniel.

I am planning on installing 12 x 270W panels with 4 panels connected in series creating 3 strings that will be connected in parallel. I will have shade in the morning (winter) on the one string. The charge controller I will be using is the MPPT 250/100 (to allow for expansion). My questions are:

1. Each string will be producing different amount of power as one string will be in the shade and the other two in full sun. Does the controller handle this?
2. How many individual strings can be connected to this controller (assuming I am not exceeding the volts or amps of the controller?
3. What is the difference between the Tr and MC4? I assume the connections? The MC4 seems to allow for 3 separate connections, so is it limited to 3 strings?

Good evening Guy.

Please advise/confirm connection of Multiplus 3000, CCGX and BMV700.

According to schematics a VE.Bus to Ve.Can interface, part number ASS030520105 should be used?

I have been informed that there are 2 versions now: Part numbers ASS030710018 VE Can to Can Bus Type A cable 1.8M, and ASS030720018 VE Can to Can Bus Type B cable 1.8M?

These seems to be VE.CAN units, and not VE.Bus?

I could not get the CCGX to communicate with the MULTI so far.

Thanks for the advice!

Hi There,

This might be quite elementary to solve, however I keep getting high voltage alarms from the Pylontech battery at times of high solar yield.

What can be done to solve the problem. The alarms tend to show up at voltages below the recommended charge voltage settings, ie max voltage for absorption charging 53.2V and Float 53V in accordance with the manual.

I have downloaded logs for some of the alarm events, these can be found at the following link.

https://drive.google.com/open?id=19c45KZUPvGrVP4q_MgFSeSdjDPtzZu3r

Where could the alarm be triggered and why, and how could the setup/settings be changed to avoid or reduce the alarm event. At present it is a once a week occurrence.

Best Regards

Riaan

Hi there community, busy with a design for a 3 phase ESS installation. I was going to use Fronius or SMA here however no stock for awhile to come. Going to need 12kW of PV so either use an ABB Trio 12kW or use MPPTs. Due to the low loads but 3 phase i have gone with 3 x 5kVA Multiplus 2s to create 3phase. Going to have a 14kWh Pylontech battery bank here which ideally would be used for daily consumption and if there is a poor grid supply to then change it to be fully charged for scheduled power outages.
Also want to make sure there is nothing i am missing. I do have a Color Control.

Thanks all.

hoi,

can someone tell when for example the quattro 8000 goes back from float to bulk again?

on what voltage?

or when he goes from absorption back to bulk, because myn can stay for days in absorption , even when voltage is around 50v ( iets an 48v battery bank)

max absortion time is set in ve.config to 6h max.

thanks kristof

After a low battery reboot the CCGX is stuck on the boot screen "Victon". I've tried soft rebooting (page and menu buttons at the same time) and the screen goes black then white then back to the boot screen.

I tried disconnecting D.C. power to the CCGX and when it boots it is still stuck on the splash screen.

I disconnected solar, ac, and batteries for 1 minute plus and when it boots it is still stuck on theboot splash screen.

Any suggestions?

In Blue Smart IP67 battery charger datahseet it is stated that it can be used as a power supply. Is there any mode select buton on the device to use it as a power supply?

Some chargers have ground/leakage currents because of the filter capacitors used in the input line of the charger. What is the leakage current (ground curent) of the IP67 Battery Charger?
