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.

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

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

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?

I am looking at the log data available from VRM and am trying to distinguish between the normal DC load and the dc load due to the inverter. It seems the current and voltage are in the logs but i am unable to find a log of the input KWhs. Is this available anywhere?

I would like to see my power usage on AC vs DC systems.

Thanks,

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

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?

We had lightning hit the electrical kiosk in the road and power was off for 2 days when power came back on the AC in is not accepting or reading any voltage it just shows 2v I have tested and and I get 230v what could the problem be.

Many thanks

I have EasySolar 24/1600 and I have same problem like this EasySolar ESS randomly switches charging-discharging mode. This problem is only in ESS mode, in HUB1 mode works stable and without problems. The problem occurs, when it is broadcast remote command on the 216,7 Hz. Tone frequency 216,7Hz is superimposed to mains during broadcast remote commands. This tone frequency is used most of the region in Czech and Slovak Republic.

Hi from a longtime Victron reseller in Colorado. I have a solar home sales opportunity where there are no code inspections--hence little worry that Quattro has no American style UL1741 label.

AC coupling or DC coupling is still undecided but either way I need approval to "sell" excess energy into the "mains". Lawfully grid-tied Victron may be a first for this side of the pond.

The public power company wants compliance with "IEEE Standard 1547 Guide for Distributed Generation Interconnection". Here's a link:

https://standards.ieee.org/standard/1547-2018.html

but is that equivalent to any of these grid code standards in VEConfig3?

The mains engineers are more likely to approve the intertie if I can document Victron compliance with IEEE1547.

How about that Victron Energy Staff? Any thoughts or help? Thanks in advance~

Hi all,

a friend has an older off-grid solution with inverter 24/5000 and lot of lead batteries.

Now he wants to upgrade with Multiplus2, BYD Box Pro 13.8, AC-coupled Fronius and CCGX.

The question is, can he use the older inverter like a generator only for emergency power ?

And will the CCGX be able to communicate with the inverter ?

to illustrate the idea.......

Hello

I have a question about battery cycling .

For example, a Victron battery Gel is give to 1800 cycle with 30% of discharge

With a solar charger regulator, I'm ok if the day the battery is charged and if I discharge the battery the night to 30% max / ok > 1 cycle

but when my regulator Victron charge the battery with the sun and when I have a load on the battery the day ( a phoenix 220V converter for example ) , the regulator can on a day pass bulk mode to absorption to float and if the sun is not enough , it pass again in bulk or absorption

So, on a bad day how many cycle count if multiple charge mode but never discharge < 30% battery discharge ?

float to bulk = 1 cycle ? > multiple cycle on a bad day ?

Thank for response

Hi, I have an installation with :

- 1 phoenix 48/3000/35

- 24 batteries Hoppecke OPzS 720 (468 Ah C10)/2V

After updating the firmware of the phoenix from 2622209 to 2622431 , i configurated the shut-down on SOC in the phoenix.

[image]

The system worked well a week and then stopped. Since that, the inverter couldn't restart.

Is the shut-down well set? How does it work? Could it be the reason of the troubleshoot of the inverter?

Thanks for your help.

All cables and mk3 switch have been replaced and proper pc programs are being used but still cant conect
