Hi again,

sorry for asking so many question in the last couple of days...I find it kind of hard to find information sometimes, seams like information is spread out on to many places and there is some stuffs that are left unknown..

so today, i notice the yellow led is flashing every 3 seconds, in the manual there is no information about that, there is 2 condition where the yellow light flash would indicate a fault but it would have to have the green or the blue led flashing too. no condition with only the yellow light flashing....

FW is v1.39

status on the MPPT is
absorption mode at 14,8v @ 6A

Pv roughly 33v @2.8A

temp is 24C
was in bulk for 4 hrs this morning now in absorption for 45 minutes

Have a 100/30 hooked up to two 175W panels. Been using it fine for about a month now. Out of the blue, it has stopped working. It charged the batteries up to 92% and then output 0W (sometimes 2-3). I unplugged everything and replugged it back in and it worked as normal again for a few hours. Then back to 0W (still reading a nominal amount of V both from the battery and from the panels). I unplugged and replugged again, this time it worked for a few minutes. But then stopped. I repeated the process and now it's not charging at all.

I have checked all the connections with a multimeter and everything appears tip top. One thing I noticed is the voltage reading from the battery terminals of the controller do not match the voltage reading from the batteries themselves.

I also wondered if it was my battery monitor being wrong, but when I turn appliances on, the charger still refuses to output any wattage. Is my unit defective? Or is there something else I should try that I'm missing?

I installed a Victron 200w Bluesolar panel and a Smartsolar MPPT 100/20 in my Campervan, charging one Victron AGM 110Ah/12V battery (I'm not a heavy consumer on power).

I used the 'Gel victron deep discharge (2)' presetting on the MPPT for this battery. This looked fine to me for my Victron AGM battery specifications.

Until now I was completely dependent on two Victron wallchargers, one 15A used for the AGM battery and a small 5A charger I installed nearby the lead-acid battery of the car.

But now that I am no longer dependent on fixed power and love to stay for weeks at the same location without moving or using the engine, I have to find a way to keep the car battery also fully charged. And this is especially important for the following winter.

Unfortunately, the roof of the campervan is not very large, and together with the 200w panel, roof domes, etc. I see no way to install an extra small solar panel on the roof to topup my car battery.

Another option would be to use my Victron Phoenix inverter and connect the small 5A charger to this inverter outlet to topup the car battery, or is this a stupid idea and not possible

I would appreciate very much your suggestions.

Is it possible to connect the old (2006) Multi plus inverter/charger to a Venus GX? If not can the motherboard be upgraded to allow it?

I am re-installing a MultiPlus as an ESS-system where it initially was designed/configured as a OffGrid system. There is an energy meter on AC1 to measure incoming AC coupled solar.

I set the ESS for 'No Grid meter' but still it is taking the solar meter as input for power balancing, leading to trying to charge the batteries from the grid even when they are almost full and plenty of solar is available.

Disconnecting the meter from the CCGX got rid of this behavior.

I updated the Venus Gx to the latest software, 2.31. Now, when I connect to it via the build-in WiFi, it keeps kicking me out. Every few seconds I have to reconnect. Any ideas?

Hi. I am new to the Victron world, having recently installed a MPPT solar controller, BMV 712, and Venus GX. MultiPlus in box to install next. All in a RV with new lithium batteries too.

All is working great so far with the exception of the Remote Console via internet with the vrm.victronenergy.com website or the VRM iOS app. I can use remote console when connected to the RV WiFi hotspot or using the built-in IP address in the Venus GX.

Other VRM functions work fine over the internet - and I have it set to update in 1 minute intervals.

I’ve spent hours reading online and trying different settings, without success.

Can someone please give me the specific settings for the Venus GX to enable remote internet Remote Console access? I think I have everything set properly - but it does not work. I must be missing something. Do I need to set SSH? What about 2-way communication?

It seems odd that all other VRM functions work fine via remote internet with the exception of Remote Console.

Thanks!

When charging from the generator-AC1(battery saver selected) or grid-AC2(keep batteries charged) the ESS profile attempts to charge the batteries to 100%. It honors the BMS restrictions of Charge Voltage/Current limits. As the lithium batteries reach 100% the BMS CCL approaches 0. When charge power is coming from an AC source the charge current from the Quattro matches the Charge Current limit, however it does not compensate for additional DC loads. ie, CCL=20A, DC Loads=14A, the resulting charge current is 6A. However, when charging strictly from solar via MPPT controllers, CCL=10A, DCLoads=6A, SolarYield=16A.

The compensation for the Solar/DC Loads only happened recently. Does this need to be added to the AC Charger as well?

I've had a BMV-712 Smart for about 2 months. Now there is no display and the app will not recognize the unit anymore. The power has been checked and is working and the other connector has been removed and reinstalled on both ends. Any ideas?

I have a MultiPlus 48/3000/35 with a BlueSolar Charger MPPT 150/70. Just upgraded to Pylontech US2000B Lithium batteries. As soon as I switch on the inverter, the values on the CCGX display start turning on and off every 2 seconds.

Question: I’m running an ESS setup with ACcoupled PV with feed-in allowed. First I was using only a mppt but for some reasons I temporarily disconnected it and only using ACcoupled PV on ac-out.

Battery setting is optimized with batterylife(because of passive balanced lithium). Al worked well, but now there is only ACcoupled PV available the systems thinks there is no incoming power and it raises the active state of charge limit so it won’t discharge anymore while there is sufficient charge current available each day.

For now I set it to optimized without batterylife but that’s not the way to go. What is going wrong here?

Setup:

Multigrid-2 48/3000/35

ACcoupled PV 440Wp on AC-out

Bmv700

RPI with Venus

8kWh LiFePo4, passive balanced

MPPT150/35(not used, but connected)

I've got a 12v 320Ah Narada Lead Carbon battery bank, a Multiplus 1200/12/50 and 3 SmartSolar MPPT 75/15's connected to 3 separate solar arrays.

The problem I'm having is the MPPT controllers tripping over each other going into float WAY too early. So on the daily chart I'll have one controller yielding as much as 1300Wh while the other two will yield as little as 200Wh each. At the end of the day the battery is not fully charged either.

The dominant controller can be any of the controllers on any given day. The wiring and settings are the same for all three controllers. I guess it just a software race condition which one detects the 1A float first. As soon as is does that 1A load goes to the remain controllers.

Is it possible to have them share better. Does the BMV or Smart Sense Synchronise them at all. As it is they are operating at about 30% efficiency once two drop out.

Seems that only one MPPT controller can be the only charge source in the circuit. Otherwise once any one hits the 1A float threshold it go to sleep and doesn't wake up again. Leaving just one controller to do all the work and the battery no where near charged.

The situation is exacerbated as the Muliplus charger starts up when the generator is fired up. All the MPPT go to sleep because the generator is providing all the charge current. Then when it is turned off often only one charge controller comes back to charge and the other two stay on float even though the battery might only be 30% charged because the float voltage being reached does not wake them all up.

These MPPT charge controllers do not play at all well with other charge sources. Including their own kind. Is there any way to have them act as a simple power supply? That is just providing a voltage to battery and allowing the battery to simply absorb what it can? Or maybe get rid of the 1A threshold or have a timer that checks periodically if the battery can now accept greater than 1A and go back to absorption.

Basically modify the algorithm somehow so they're get back to work when they can. At the moment it's like having an employee that gets things done in the morning then goes to sleep and doesn't bother checking if more work has arrived because the other bloke is doing it all by himself and struggling at it as a result.

Seems theses things are too smart for their own goodand as a result are constantly tripping over each other. After which they don't get up and back to work again for the rest of the day! If it was an employee you'd fire them for not being team players! Lol

Is it possible for me to just move the charge leads from the battery connector to the output connector? If the MPPT can output 15A at say the float setpoint voltage to the output without a battery in the battery connection then that would be better charge controller than all the current "smarts" before the battery connection terminals!

Any solution would be appreciated.

Cheers,

Hello,

I have just installed Easysolar 24/1600/40-16 and Venus GX. I have connected Venus GX with ethernet cable to Easysolar's left RJ45 plug. I have also succesfully added Venus GX to VRM, but I cant get it connected to Easysolar. Should it find it automatically or do I need to do something?

I get no information on VRM atm. Only Venus GX online...

I have 2 12v 160W solar panels wired in parallel. They are wired to my batteries and a MPPT 100/50 SmartSolar Charge controller. The system has been working fine for the last two weeks since I set it up. Yesterday, however, I came out to find that the victron connect app is showing no wattage or voltage coming into the charge controller from the panels. I have measured the current coming in from the solar panels and there is no problem there. They are showing the voltage i expect. The polarity is correct from the battery connection as well as the solar panels to the charge controller and has never been connected wrong. My charge controller is showing no error code on the led light. The bulk led is flashing once every 3 seconds.

Did my charge controller go bad?

Hello,

Does using the Multiplus II optional current transformer remove the need for an energy meter when PV is connected on the input side of the Multiplus?

Hello.

I have a Victron Quattro, CCGX panel, VE Bus to NMEA cable and a VE CAN to NMEA cable.

These 4 items are all connected as per Diagram 1.1 here:
https://www.victronenergy.com/live/ve.can:nmea-2000:start

Data from the Quattro reports fine on the CCGX (NMEA bus OK) - However I am unable to change the Quattro’s mode (On/Off/Charger Only).
The CCGX screen shows the mode change, but nothing actually changes on the Quattro.

Further down on the page link above I did notice that the VE CAN is stated as being “read only”
CCGX does not send any information to the N2K network.

Does this mean the CCGX it will not send out the required data to request the Quattro change mode?

I must add that what I am ultimately trying to achieve with this equipment......

1) I want to have the ability to control the Quattro ON/OFF from the CCGX panel.

-I do not need (or want to) to send any commands from our systems NMEA network to control the Quattro.

2) I would like our vessels NMEA network to be able to monitor the running state of the Quattro.

Best Regards

Hi !

I have recently bought a Bluetooth Dongle to adjust parameters on the MPPT (Bluesolar 150/70) in mye Easysolar 24/3000.

I have big trouble being able to sustain a connection (with a non-flashing blue light on the dongle), and the app on my mobile keep reloading. I have been able to do what I want and have a connection over a few minutes a few times but now I cant anymore, and only once of maybe 20 attempt yesterday did I see the Bluesolar MPPT picture come up on the screen after searching for devices.

The conection to the CCGX works, but it is very easy to pull out. I can also mention that it was not connected when I received the Easysolar one year ago.

I am afraid that if I try to anjust prameters on the MPPT it might cut the process half way and I will be left with and MPPT that I dont know the charging settings for, and that I can not access or change settings on.

What can I do?

I am considering changing the MPPT to a Smartsolar, but this would be a waste of money since the MPPT works fine (althought it has a peak absorption value that is alittle to high -this is what I would like to alter).

How complicated is it to change the MPPT in my Easysolar? And can I upgrade it to a stronger MPPT if I want -if so what which MPPT would be the strongest MPPT I could put into the Easysolar?

Great to be able to ask questions here ! :-D

Sincerly,

I have a Quattro that is charging a large 24v lithium battery set up with the two signal BMS support assistant to control the BMS charging. I can't seem to get the quattro to prioritise the inverter to consume the battery power, in fact the only way I can stop it taking energy from the grid or solar inverter is to isolate the mains input. Do i have to have a Venus GX or Colour Control to set this up?

Any help would be appreciated.

if i put 2 LFP battery 12.8v 60 amp in series and the starting current for the truck reach 600 Amp what happens to the lithium battery?

I’d like to use a temperature sensor connected to my BMV 712, and have my MPPT 75/15 receive that temperature data wirelessly. I currently have a shunt connected to monitor battery battery voltage, but there’s only room for one shunt to be connected to the 712. I can find no manual specific to the temperature sensor, and the manual for the 712 does not provide enough detail on connecting sensors/probes.

Three questions:

1. If I connect the temperature sensor probe, does it also communicate battery voltage to the BMV 712, or must I have two sensors installed, one for temp and one for voltage?

2. For the temperature sensor to function, do I need to select the temperature as the auxiliary input on the BMV 712?

3. And if I do need to set temperature as the auxiliary input, then how do I get the BMV 712 to monitor my starter battery in addition to my house bank?

Regards,

Ed
